5.0 out of 5 stars Great Watch for the Right Expectations February 5, 2010

I ordered this watch for my 20th birthday, and it's been 11 days that I've worn it so far. I love it. Here's my review:

Casio's SGW100-1V (Sports Gear Watch 100-1V), offers an above-average set of capabilities for its price range. I bought this watch for its high water resistance, sleek-rugged design, its 10yr. non-solar battery, and water-blue accents on the face. Also, it just looks sexy in person. I can never stop staring at it.

The Watch band is made of a sturdy, pliable, resin in Black color, fits snugly around the wrist and is comfortable to wear. Usually, I wear my watch bands all the way to the bottom of the wrist, but the face of the watch is almost two inches and there is some restriction with the dial when I move my hand up and down. So I had to wear this a little above where I like to have my watches. However, because the watch doesn't move around, it can stay there all the time without re-adjusting at all. It looks a lot better there anyway.

The Dial or Watch face is slim, but pretty wide across. The case is 1.87 inches in diameter and 1.32 centimeters (or about a 1/2 inch) thick. It might sound big, but it's really slim to wear. It doesn't look bulky like the G-shocks, but it's got the same rugged accents to go with it. Six top dial screws add durability, protection, and an asthetic element to the face. The watch is extremely easy to read while wet or dry, thanks to its clear display and face size. The numbers and letterings are crisp and clear in any light. The dial also has a teal colored backlight that illuminates the digits and characters only, instead of the whole face, which makes identification easy on the eyes at night. Don't expect to use the light in place of a flashlight though, because it lights for approximately one second (timed using the watch) and is not bright enough for anything else. Also, the light is electro-luminescent and its power and duration will diminish when the battery becomes too low signaling that it's time to replace.

The watch's main features include the "Twin Sensor", compass-thermometer device functions. Readings are displayed digitally as an arrow and degree for direction and degrees in F or C for temerature. They last for 10 seconds before going blank and returning to the Timekeeping Mode by default.

Neither of the two sensors are as accurate as their authentic instruments. The Twin Sensor does give average, general readings. However, that is to be expected given that the watch is to be worn and not always situated perfectly horizontal. The instruction manual does provide that "The measurement functions built into this watch are not intended for use in taking measurements that require professional or industrial precision." Some drawbacks in calibration include that the compass be re-calibrated every 3 months for accuracy (reccomended) and that the watch must sit for 30 minutes when being re-calibrated for temperature to acclamate to the surrounding air. It takes readings while on the wrist though, so I don't know what people are saying about taking the watch off every time to measure temperature or direction. It works on the wrist.

What I like about the watch though is the 200M water resistance. Standard Casio depth. Not that I'm going to be going that far down, but it's a nice ensurance.

Without hard suits or sub-marine vehicles, a safe diving limit for humans is around 100ft. 200M and below, being the hazardous limit. So, as with the Casio G-shocks, where the watch will survive as much G's (acceleration due to gravity) taken as the human body can accept, Casio also provides the deepest limit the human body can safely endure under pressure of water.

Like all of the other Casio wathces, it's got the basic setup of funtionalities for Local Time, Date/Day, World Time, Stopwatch, Timer, and an Alarm which boasts a set of four different alarms, an hourly alarm setting, and an optional snooze timer. You have the adjustment button on the top left, Light buttion on the top right, Mode on bottom-left, and Comp (computer for compass and thermometer readings) on the bottom right.

So for under 50 bucks, the Casio SGW100-1V offers a variety of funtionality, a solid construction, and clean design elements. The watch is perfect for surfing. It's not heavy, but light on the hand and easy-to-read, good solid watch. Just be sure to replace the battery. As with all watches, it's reccomended that you know what you're getting to get the most for your money. With this watch, I got all I wanted/needed, so that's why I rated 5/5 stars. Thanks for reading, hope this helps.

This is a great watch. About accuracy: After performing the compass calibration, I can say it is fairly accurate. I always get acceptable direction of where the north should be. Temperature is also accurate but it is true, you need to take off the watch for about 10 to 15 min to get a good reading. If not, then you get a constant 31 degrees.
About size, I think it does has a very good size, big numbers, clear display and very nice to press buttons.
Band is resin.
I gave 4 stars because I think alarm is dim but that is just a personal point of view.
Very nice to use. In all, I am happy with my purchase.

Update dic 21 08: Yes, time is display normally in the central area of the screen, where the 330° is shown on picture. This picture here in amazon shows the compass mode. I have added some images for size and display info.

By Somedayscratch

I was looking for a watch with a compass built into it to use when on holiday in strange cities so that I could get oriented after getting out of subways, etc. This was the least expensive of the bunch. It works great and has helped me to navigate home from the pub already! If you don't need an altimeter or anything like that it serves the purpose.

Product Description

Amazon.com

Innovative technology and sleek, sporty style combine in Casio's Twin Sensor Watch #SGW100-1V. Temperature and direction readings make this rugged timepiece ideal for workouts, outdoor adventures, and water sports. There's also world time (29 time zones/48 cities), declination correction, a convenient stopwatch, four daily alarms and one snooze alarm, auto calendar, and a mineral glass for extra protection against scratching. Direction readings and time are indicated on a large LCD that is divided into three segments for a clear, easy-to-understand display. Water resistance to 660 feet and a rugged resin band ensure durability, while digital quartz movement provides reliable precision.

The Casio Story

With the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.

In developing its own wristwatches Casio began with the basic question, ""What is a wristwatch?"" Rather than simply making a digital version of the conventional mechanical watch, we thought that the ideal wristwatch should be something that shows all facets of time in a consistent way. Based on this, Casio was able to create a watch that displayed the precise time including the second, minute, hour, day, and month — not to mention a.m. or p.m., and the day of the week. It was the first watch in the world with a digital automatic calendar function that eliminated the need to reset the calendar due the variation in month length. Rather than using a conventional watch face and hands, a digital liquid crystal display was adopted to better show all the information. This culminated in the 1974 launch of the CASIOTRON, the world’s first digital watch with automatic calendar. The CASIOTRON won acclaim as a groundbreaking product that represented a complete departure from the conventional wristwatch.

Casio transformed the concept of the watch — from a mere timepiece to an information device for the wrist — and undertook product planning based on this innovative idea. We developed not only time functions such as global time zone watches, but also other radical new functions using Casio’s own digital technology, including calculator and dictionary functions, as well as a phonebook feature based on memory technology, and even a thermometer function using a built-in sensor. The memory-function watches became our DATA BANK product series, while the sensor watches developed into two unique Casio product lines of today: the Pathfinder series displaying altitude, atmospheric pressure, and compass readings.

In 1983, Casio launched the shock-resistant G-SHOCK watch. This product shattered the notion that a watch is a fragile piece of jewelry that needs to be handled with care, and was the result of Casio engineers taking on the challenge of creating the world’s toughest watch. Using a triple-protection design for the parts, module, and case, the G-SHOCK offered a radical new type of watch that was unaffected by strong impacts or shaking. Its practicality was immediately recognized, and its unique look, which embodied its functionality, became wildly popular, resulting in explosive sales in the early 1990s. The G-SHOCK soon adopted various new sensors, solar-powered radio-controlled technology (described below), and new materials for even better durability. By always employing the latest technology, and continuing to transcend conventional thinking about the watch, the G-SHOCK brand has become Casio’s flagship timepiece product.

Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, and the radio-controlled function means users never have to reset the time. In particular, the radio-controlled function represents a revolution in time-keeping technology similar to the impact created when mechanical watches gave way to quartz technology. Through the further development of high radio-wave sensitivity, miniaturization, and improved energy efficiency, Casio continues to produce a whole range of radio-controlled models.
