The Regulus watch by Nixon is inspired by the Special Operations community and as such, it's super tough, shock absorbing, and durable. Functions include dual time, time of day (12 or 24 hour), day/date, auto calendar through 2099, dual chronographs with 1/100 second resolution visible from all mode screens, count down timer, 3 independent alarms, adjustable LED backlight, and silent mode.Tested waterproof to 100 meter/10 ATM (good for all water sports except diving), the 46mm custom injection molded TR90 case with polycarbonate pushers looks sleek and the tapered, custom injection molded, free-swing TPU 80 band is comfortable to wear. A water flow texture on the skin-side of the band, patented locking looper, and stainless steel buckle with stainless steel screw bar complete the timepiece.
