The New Sinn 657

Tough solar, shock resistant with a 7 month power reserve.Waterproof to 200m (660ft)Mineral crystal, well-protected by the bezel and protecting plastic bits.Analog hour and minute hand, seconds are on the 3 o'clock LCD displayStopwatch, 1/100th second resolution, up to 1 hour.6-minute countdown timer.Automatic backlight that illuminates on wrist twist in the dark. Illumination is a yellow LED at 6 o'clock, so the LED displays are not readable.Single *** alarm, optional hourly chimeMetal case, resin band.5-band 'atomic' timekeeping, meaning that it receives radio signals up to six times per day to set the time.I had previously owned a GW-1310, and this is a nice improvement in small ways: The hour hand makes the time more readable at a glance, and the bronze bezel is understated and attractive. The watch is quite subdued as G-Shocks go, with the reverse LCD displays giving a nice touch of the unusual. The AWG101-1V also has some other improvements that I greatly appreciate. For one, you can see in this picture that the band has notches on the inside. You don't notice them while wearing it, but the strap keeper is held in place by them, and thus the end of the strap doesn't work loose while you're active. A nice touch, that.Casio also added luminescent material to the face of the watch on the hands and indices, which unfortunately fades quite quickly.
