Casio Men's WVA430J-1 Waveceptor Solar Atomic Ana-Digi Sport Watch

With this non-stop, self-adjusting Casio Waveceptor timepiece, you don't have to worry about replacing batteries because it's solar powered and you'll have confidence of always knowing the correct time via the integrated atomic timekeeping technology. This stylish watch is suitable for both professional and casual wear, and it's complemented by a contemporary black resin strap. It includes a stopwatch function that can measure events down to 1/100 of a second for the first 60 minutes (and down to 1 second from 60 minutes to 100 hours), and it offers elapsed and split time modes, and 1st-2nd place times. Other timekeeping features include:

• World Time: 29 time zones (30 cities), city code display, daylight saving on/off
• 3 Daily Alarms
• Hourly Time Signal
• 12/24 Hour Formats

This timepiece also features an Auto Calendar (pre-programmed until the year 2039), ±15-second accuracy per month, Afterglow backlighting, and water resistance to 100 meters (330 feet)--offering protection from accidental splashes as well suitable for swimming, snorkeling, and light recreational diving. This solar-powered watch has a battery life of up to 5 months on a full charge (without further exposure to light).

This multi-band radio-controlled watch receives a time calibration signal transmitted from several locations across the globe (the U.S. and Japan), and it has an auto receive function (up to 6 times per day). You can choose to automatically receive this signal four times a day, or manually update the watch to the atomic clock.
