Historically limited to military personnel only, the Regulus Mk-1 is not your ordinary outdoors digital watch. It’s designed for the elite. The only features included are those guaranteed to get your back during a pinch, including day and date, auto calendar through 2099, dual chronographs, alarm, silent mode and adjustable LED backlight. The ultra-durable and shock-absorbing case goes anywhere you go. The comfortably high-tech band never leaves your wrist. If you know, you know.
