Housed in a round 42mm stainless steel case, this Aquaracer Professional 300 is built around a uni-directional rotating black ceramic bezel and a scratch-resistant sapphire crystal. The screw-down crown and solid case back contribute to water resistance rated at 300 meters / 1,000 feet, making it a serious tool watch for aquatic environments.
The black dial is fitted with silver-tone hands and baton hour markers, both treated with luminescent material for low-light legibility, alongside luminescent dot and index hour markers and minute markers circling the outer rim. A date display sits at the 6 o'clock position, rounding out the core time-and-date functions.
Power comes from an automatic movement with an 80-hour power reserve. The stainless steel bracelet is secured by a fold-over clasp with a safety release. Swiss made, this example is accompanied by its original box and papers.
