Moon phase
Eco-Drive radio-controlled watch with world time and perpetual calendar
At first look, you wouldn't know it from the classic-looking BY1030-50L men's model with moon phase function (full moon to new moon), but it's packed with numerous features.
These includes a light-powered and radio-controlled Eco-Drive movement (Radio Controlled), which receives signals from atomic clocks around the globe, a perpetual calendar, world time and a power reserve indicator.
This watch also has a sapphire glass and is anti-magnetic. The model is equipped with a blue dial on a stainless steel strap.
