The STS ‑99 Chronometer launched our Mission Collection and quite literally went to space. The original Towson watch accompanied a NASA astronaut aboard Space Shuttle Endeavour on mission STS ‑99 in 2000. This commercial edition faithfully recreates that timepiece with a COSC‑certified movement and a gold‑plated rotor hand‑engraved by Jochen Benzinger. Its 40 mm stainless steel case, satin‑brushed with sapphire crystal, houses a high‑contrast dial designed for legibility in microgravity and Monday meetings alike. It’s a slice of orbital history you can strap on your wrist — minus the zero‑G training.

A standard triple- chronograph display of engine-turned sub-dials and a stamped textured center, featuring painted roman numerals and indices. Marked with the TWC initial logo. The triple-chronograph includes a minute counter at 12 o’clock, sweep-second at 9 o’clock and hour-counter at 6 o’clock. Surrounded by a tachymeter. The minute, hour and chronograph hands operate from the center with a push-pull crown and start/stop pushers aside it. The high-polish case is water resistant to 50 meters, shock absorbent, and capable of being worn in space. An exhibition case-back reveals the Swiss Caliber 7750 movement that is decorated, assembled, and calibrated in-house.
