Citizen Perpetual AT
Citizen Perpetual Calendar A-T watches have it all! They synchronize with the atomic clock for accuracy within milliseconds, are powered by light so you never need to change a battery, and automatically adjust for months with 30, 31, 28 or 29 days. The correct time every time, all the time -- it doesn't get any more carefree than this. Citizen also has a 5 Year Manufacturer Warranty, one of the longest in the industry.
