It displays hour, minute, second, date, and day of the week functions, powered by the H-40 caliber with an 80-hour power reserve. This timepiece is designed for everyday wear, offering Super-LumiNova illumination, a sapphire crystal, and water resistance up to 10 bar (100m).
Decide between quartz (accurate, low maintenance) or mechanical (craftsmanship, sweeping hand, requires servicing). Match the case diameter to your wrist size to avoid looking disproportionate. Available from $1,125.
