Advantages

The combination of a resin case and stainless steel band provides durability while keeping the watch lightweight and comfortable for daily use. LED illumination ensures readability in low light, while the 1/100-second stopwatch and daily alarm add practical timing functions for routines and short activities. The automatic calendar and 12/24-hour display reduce the need for frequent manual adjustments. A seven-year battery life minimises maintenance frequency.

Replace the battery only with compatible types and have seals inspected if the watch is exposed to moisture often.
