TIMEX MK1 Aluminum Chronograph Watch 40 mm

Rugged Military-Inspired Chronograph

The Timex MK1 Aluminum Chronograph Watch combines a lightweight bronze-tone aluminum case with a durable army green fabric strap for outdoor utility and retro field styling. Its olive green dial features luminescent silver-tone hands and Arabic numeral hour markers with a fine minute track around the rim. A multi-functional quartz chronograph movement powers three sub-dials tracking 60 seconds, 30 minutes, and 1/10th of a second alongside a date window at 4 o'clock.

30 Metre Splash Resistance Limits

Water resistance is rated to 30 metres or 100 feet, protecting the movement against everyday splashes and brief immersion only. The scratch-resistant mineral crystal and solid case back shield the dial and mechanism from daily knocks. A pull-push crown operates the chronograph functions and time setting without a screw-down seal, so the watch is not suited for swimming, diving, or sustained water pressure.

Upgrade From Basic Analog Field Watch

This model replaces a simple time-only field watch by adding full chronograph timing, a date complication, and luminescent hands for low-light legibility. The jump is worth it when you need to measure elapsed intervals down to 1/10th of a second or track a second time zone using the sub-dials. Buyers who want a slimmer profile under 13 mm thickness or a bracelet instead of a fabric strap should look elsewhere.
