Eco-Drive power and radio-controlled precision
At the heart of the watch is the Eco-Drive solar power system, which converts any light source into energy. A fully charged battery keeps the watch running for up to 10 months, even in complete darkness, and a power-saving mode is also available for extended life. Absolute precision is handled by radio control, which automatically receives signals from atomic clocks in Europe (DCF), the USA (WWVB), Japan (JJY), and China (BPC). This means the time and calendar adjust themselves, so you can always rely on the correct data without manual corrections.
Durable construction and practical features
The watch is designed for demanding conditions. The case and strap are made of stainless steel, and the dial is protected by a sapphire crystal, which is exceptionally scratch-resistant. With water resistance to 200 metres (20 ATM), you can confidently use the watch for swimming or recreational diving. For measuring time intervals, you'll appreciate the chronograph with 1/20-second accuracy and a measuring capacity of up to 60 minutes. Other features include a fully automatic calendar, a world time display, and a 24-hour indicator.
