new nokia x5 reviews

Nokia has a tradition of delivering handsets that are designed a little different from the norm, and the Nokia X5 is the latest in this line up of quirky handsets. Part of the X Series range of phones, the Nokia X5 is designed to be noticed and get you noticed. But unique looks are not enough to make a mark on their own, the style needs to be backed up with a certain amount of substance, and we’re going to take a closer look at the X5 to see what secrets are laying beneath the square shaped body.

The square design is instantly recognisable, although the X5 is not perfectly square, measuring 74.3 x 66.4 x 16.8mm. At almost 17mm, the Nokia X5 seems to be rather chunky, but the reason for the thickness is because Nokia have included a full, four row slide-out QWERTY keyboard, for quick and easy text entry. The keys are compact, and laid out with no space between one key and the next, but each key is slightly rounded on top, to help with ensuring quick, but accurate data entry. The main display on the device is a QVGA TFT display, supporting up to 256,000 colours, measuring 2.36 inches from point to point. Directly above the screen sits the earpiece, and to one side of this is the light sensor. Common on most Nokia devices, the light sensor allows the device to automatically control the keypad backlight, determining whether the ambient lighting conditions require the keypad light to come on, or not, which is a great help with preserving battery life, by not lighting the keypad when it is not necessary. The shape of the phone means there is ample space for the main navigation controls on the phone; located directly under the main display, the central, 5-way Navi key is flanked by two soft option keys, and the call send/end keys. On the far left is a key with a home symbol on it, which accesses the main menu, whilst on the far right of the device is the dedicated music key. (more…)

two style of modification

Young people always want their vehicles to looks fierce and sporty, they had to do a lot of modifications on their car such as the addition of accessories and make the settings so the performance of their cars increase. generally, modification can be separated by two part there is simple modification and total modification.

simple modification

simple modification is modification that limited to maximize the physical appearance of their vehicles like adding billet grills, adding bumper and spoiler, while total modifications are modifications that alter the overall weight of the car which include physical changes and changes in the engine.

total modification

so what type of modifications are you? make sure that matches your taste and style.

seiko movements

When the word Seiko is thrown around in casuall conversation,most consumers think good quartz watches. Even those that have come to recognize seiko with quality usually think in terms of the ubiquitous automatic,the 7s26. Here it is in a dejeweld version,the 7002.

While it can be agreed that the 7s family of movements are very functional,theres a economy of form that is readily apparent in the finish.

But it wasnt too long ago that if you bought a Seiko,You where getting a serious peice of horology.

I`d like to take a short step back in time,and show you some Seikos that really packed a punch. All of these save one are from my personal collection. All are heavily jeweled,most offer hand winding. For those that think of Seikos as a lower branch on the tree of horology,I offer these pictures. Unfortunately,I hav`nt listed these in eny particular order. I have removed the winding rotor in almost all examples,so as to give the reader a better look at “what makes them tick”. I will try to add what specifacations I know about the movement,but as always,if I Boo-Boo,or omit something,please feel free to correct me,or add aditional details I`m not aware of.

Let the show begin………….

Below is the Cal 5246. A high beat movement,its beating at 28,800 bph. Covered in 25 jeweles,it has a micro regulator. It can be handwound,both day and date can be quick set at the crown,and the second hand can be hacked (stoped for accurate time setting).

seiko sumo reviews

INTRODUCTION

I’ve owned a large variety of watches in the past year. When money was coming in nicely and all was well, I had the luck of getting to “rent” (I say rent as I had to resell them in short order) two phenomenal Omega watches: the Speedmaster Professional and the 2254 Seamaster Professional. When things got rougher and a lot of my industry went out of work (we’re largely freelancers) I had to settle for something a little less. After a brief flirtation with Suunto watches, I returned to mechanical movements happily with Seiko’s 6R15 lineup. The Green Alpinist was my first, and ended up being just not quite my style. I reviewed earlier in the spring. While the outer appearance may not have suited me perfectly, the 6R15 movement was incredible. It kept time nearly as well as an Omega but for a fraction of the price. I found myself in -4 / +4 territory per day, and that was precisely where I wanted to be. Trading off the Alpinist, I decided to go for a watch I had casually looked at many times in the past.

THE INITIAL IMPRESSION

You’re greeted by a familiar sight when you pop open a box with a JDM (Japanese Domestic Market) Seiko. A white outer carton, and a stronger cardboard presentation box inside. Instructions (Japanese and English) for the watch itself and warranty info are usually packed in the white carton as well. Open up the presentation box and you’re greeted with a plastic wrapped Seiko with several hang-tags (in Japanese with Yen values) on a tiny pillow. While nothing particularly fancy, I’ve been keeping watch bands in this presentation box and swap them out often… that means the box itself has gotten a great deal of usage (above and beyond just bringing the watch to you) and has not shown any wear and tear. The box seems to be coated with an almost fabric like substance which appears quite durable.

The Sumo is, indeed quite large and immediately pops at you inside the box.

THE CASE

The Sumo has a very “Seiko” diver appearance about it. At first glance Seiko divers often appear to be a playful interpretation of the Submariner style. At closer examination, you’ll find much more to them. I lovingly refer to this particular watch as my “Cartoon Rolex.”

By “Find much more” I actually mean that this watch pays homage more to older Seiko divers, and bears a great deal of influence from modern Omega divers. The case itself reminds me a great deal of the 2254 I had, and the Planet Oceans I have held. It is close in heft and quality to the Planet Ocean, as it is a bit thicker than the 2254. The lugs too are curved in a very similar way, but do not end up “completing the curve” down to the connection with the pin. I would prefer that this curve continued in a Speedmaster Professional way, rather than terminating sharply as it does. This particular edge is at odds with the rest of the case; it simply is not finished as well. A little bit of polish by a watchmaker to soften this would go a very long way. All is forgiven though with the inclusion of drilled lugs. How on earth did I get by without these before? It’s so easy to swap things on and off with only one simple tool, and because of this I can actually change the watch in a matter of minutes every morning based on what I’m wearing on that given day. I understand the design motive of removing these for a clean surface, but they’re just so damned useful.

Another lovely innovation on this watch is the bezel guard. The bezel (described in depth later) is very thick, and without this guard I’d imagine it would be bumped frequently. It’s a great consideration and it plays well with the other curves on the side of the case. I haven’t seen anything like it on anything else, and others should really consider such a feature. At first I was concerned that my fingers might be pinched when turning said bezel by this guard… not at all. It is well finished and smooth, and the curve of the lug travels up to meet in in a way that ensures you’ll never be caught. Excellent design.

The bottom of the case is very nicely to fit around the wrist ever so slightly, and has no sharp edges in any way. The back is of brushed texture but has that nice Seiko Diver “Wave” emblem just as a Speedmaster would have the Seahorse in the center.

THE CROWN / THE MOVEMENT

I’ve opted to put these two categories together simply because the crown is an extension of the movement: it is the only part of the inside that you the wearer will interact directly with.

The crown itself is very slightly inset into the case of the Sumo, and when fully screwed feels exceptionally sturdy. It grips very easily and the machined “S” looks extremely nice in person. A few counter clockwise screws and the crown pops out. This at first felt a bit rough, as if there was a little sand in caught inside. Over the past two months this has smoothened out immensely and feels quite similar to the 2254 when unscrewing.

The crown wobbles a bit when fully unscrewed. I don’t particularly like this, but I do hand wind it frequently (I do miss that Speedmaster) and it hasn’t posed any problem thus far. The watch hacks when fully extended, and given that it runs ever so slightly fast (about +1 per day) I’ve only had to re-calibrate it for the atomic clock three times (I don’t like it going over 15 seconds fast) since I’ve owned it.

This leads into the movement itself, which is absolutely fantastic. As I mentioned before, this Sumo gains less than a second per day. A lot of physical activity or running around (I wore this watch while performing a large move, for example) and it will run perhaps closer to +2 per day. As a rule I wear a watch when I sleep, so I do not regulate it by placing it in a specific way overnight. Some would argue that this Seiko doesn’t beat at a fast enough rate, but you really can’t take such a complaint seriously for what is a very tool-like watch. This movement isn’t about horological fanciness, it’s much more about solid, reliable timekeeping.

THE DIAL / THE BEZEL

The Sumo has an excellent dial. Extremely readable, you are always able to tell where 12 o’clock is and everything has a wonderful rim of highly polished silver around it so even if the lume dies (impossible) you’re still able to catch light and quickly read it. The lume itself is absolutely phenomenal, and may actually keep you awake if you’re sensitive to light when you sleep. If I go to sleep at midnight, the watch is easily readable until the sun rises again, or if I have the blinds closed it retains its glow for beyond 7 hours.

The Hands are finished in identical fashion with generous lume, and will remain lit just as long as the dial. I find this style of hands to be much more useful than the Seamaster Bond style hands, and they do an excellent job for very quick (sub one second) glancing to read the time. The second hand does not have as smooth a sweep as a more expensive diver, but this is due to the slower beat rate of the movement. Again, I feel that this is an acceptable sacrifice.

The Bezel is by far the most pleasing thing about this watch. Large and easy to grip (though less easy to grip underwater) the bezel on mine is quite solid and has no play whatsoever. It squeaked a bit at first but now only makes two types of click: solid on each minute, and a smaller less solid click at the halfway between each. Frequently used for the timing of things (how long has that laundry been in the machine?) the bezel is incredibly useful around the house and shows no sign of wearing down / loosening so far.

This area of the watch is finished off with a Hardlex crystal. I’d of course prefer an AR coated Sapphire, but I see no reason to switch to one until the Hardlex is scuffed up. It may not be as clean / clear as a Sapphire but it is domed slightly so you don’t get a reflection from any angle that will obscure the view.

My Sumo is blue, and is far more subtle than the blue I’ve seen on the Ti Samurai. In direct sun light it’s a very rich blue that pops, and inside it is a darker navy blue. I’m glad that I was able to get this color rather than the black, as I think it goes incredibly well with the design.

THE INCLUDED BRACELET

The Sumo has a very interesting lug design for such a large watch: rather than taking a 22mm band, it takes a 20mm. This reminds me in many ways of the older Seiko divers with cushion cases, melded with the Omega curved lug. I personally like this design very much, but I can see some people being turned off by it.

Consequently, the included bracelet can at times look a little odd on the Sumo as it doesn’t really “flow” from the case design as many other bracelets do. While quite squeaky at first, the Sumo bracelet quiets and wears in very nicely over time, and ended up being a good though not perfect wear option for me personally. It is finished quite well with soft edges and a sturdy buckle, though I’d definitely like to see some kind of screw system for removing links rather than the pin and collar setup it has. The highlight of this bracelet is certainly its solid end links, which do try to make some sort of reconciliation with the case design.

I personally only wear the bracelet when I travel, and want a little extra security in keeping such a large and nice looking watch on my wrist. I really prefer the Sumo on my brown NATO strap, and with the black rubber band as shown below. Because of the 20mm lug size, you’ve got an incredible wealth of options for accenting a Sumo. And because of the drilled lugs, you can swap them off and on easily.

OVERALL

The Sumo is an excellent watch, and if Seiko had sold it for $1,000 rather than what it goes for now, I don’t think anyone would have complained. It is finished incredibly well for a watch at this price point, features a movement that keeps amazing time for a mechanical, and appears to be very sturdy. If you’ve been looking at the Planet Ocean and wishing that it were just a little less expensive or perhaps felt that the price would keep you from wearing it outside or while doing things that would fulfill its purpose, the Sumo might be a perfect watch for you.

knife review | master of defense

Masters of Defense came around in the late 90’s and produced some deadly designs, all of which were collaborations with well-known knife makers or martial artists and self-defense instructors. After they were sold to Blackhawk!, these were made with cheaper materials such as 440C steel instead of 154CM steel, and the Duane Dieter name was removed from the brand.

I’m not sure exactly when the transition occured, but this model is pre-blackhawk, and is incredibly well made. It harkens back to the days of the old Microtechs, and certainly brings back great memories of the all the top-quality US-made knives of yore. Its no secret that Blackhawk! is not liked by many in the online knife-world, but I really can’t comment on their quality since I never owned nor have I handled their products.

The Dieter CQD has fantastic ergonomics, and is designed to work well in a gloved hand, since many military users often wear gloves when operating their knives. The grip-tape is fantastic for retention and there are two ridges on the front of the handle that prevent your hand from slipping onto the blade. The blade is a modified spear point design by Vaughn Neeley, founder of Timberline Knives.

There is a discreet saftety on the thumb ramp of the handle, which works well. The carbide glass-breaker is also at the front of the handle, making it impossible to use unless the blade is closed. This is probably a good idea. The back end of the handle has a line/seat belt cutter, which is well concealed so that you can’t accidently cut yourself with it. The reversible pocket clip is only for tip down carry, which is also probably a good idea since otherwise you might accidently catch the line cutter on your pocket and cut that up.

Blade is black, and razor sharp. This Masters of Defense version was available in Bead Blast as well as Damascus and PVD coated blades. The current Blackhawk version appears to only be available in black.

The CQD is probably my favourite automatic knife in my collection at the moment, with a quality unmatched by any automatic in this price range. While I can only speak for the MOD version, this is still relevant to collectors purchasing on the secondary market. The Blackhawk version, while designed in a similar style, may not have the same level of quality in the finish.

Blade Length: 3.75”
Overall Length: 9.5″
Blade Material: 154CM Stainless Steel
Blade Finish: Black PVD coating
Handle Material: CNC Machined 6061-T6 Aluminum

bright orange bike review

SE Bikes and DC Shoes have done an exceptional job over the years at meeting the demands of riders with its collaboration efforts. The two companies first collaborated in 2007 with ‘30 Years of Radness’, a limited edition project to celebrate SE’s 30-year anniversary. Coming to the market in 2009 was the DC x SE PK Ripper Fixed Gear, which received mixed reviews. Today, DC and SE have teamed up once again to bring you a PK Ripper Fixed Gear for 2010.

After 2 months of rigorously testing the 2010 model, we have reached a consensus on the latest PK Ripper:

In 2009 the DC x SE fixed gear collaboration captivated the fixed gear world with its appeal – and this year’s revamp is turning out to be no different. Like its predecessor, the PK Ripper for 2010 is a fixed gear bike with accents of nostalgic BMX influence. Its floval tubing, bear trap style pedals, landing gear fork, and loop tail rear end are some of the hallmarks found on the PK Ripper that were prevalent in the ’70s BMX era, including some of the earlier PK Ripper collections.

next apple iPhone 4G

You are looking at Apple’s next iPhone. It was found lost in a bar in Redwood City, camouflaged to look like an iPhone 3GS. We got it. We disassembled it. It’s the real thing, and here are all the details. Update: click here to see the iPhone 4 definitive guide, with all the features officially announced by Apple.

While Apple may tinker with the final packaging and design of the final phone, it’s clear that the features in this lost-and-found next-generation iPhone are drastically new and drastically different from what came before. Here’s the detailed list of our findings:

What’s new

• Front-facing video chat camera
• Improved regular back-camera (the lens is quite noticeably larger than the iPhone 3GS)
• Camera flash
• Micro-SIM instead of standard SIM (like the iPad)
• Improved display. It’s unclear if it’s the 960×640 display thrown around before—it certainly looks like it, with the “Connect to iTunes” screen displaying much higher resolution than on a 3GS.
• What looks to be a secondary mic for noise cancellation, at the top, next to the headphone jack
• Split buttons for volume
• Power, mute, and volume buttons are all metallic

What’s changed

• The back is entirely flat, made of either glass (more likely) or ceramic or shiny plastic in order for the cell signal to poke through. Tapping on the back makes a more hollow and higher pitched sound compared to tapping on the glass on the front/screen, but that could just be the orientation of components inside making for a different sound
• An aluminum border going completely around the outside
• Slightly smaller screen than the 3GS (but seemingly higher resolution)
• Everything is more squared off
• 3 grams heavier
• 16% Larger battery
• Internals components are shrunken, miniaturized and reduced to make room for the larger battery

How it was lost

Here is a detailed account of how the phone was lost. (more…)
