Housed in a 43mm dodecagon-shaped stainless steel case, the Aquaracer Professional 300 presents a blue dial fitted with silver-tone luminescent hands and luminescent index and dot hour markers, with minute markers running along the outer rim. A date display sits at the 6 o'clock position, while a uni-directional rotating ceramic bezel in blue and white with a 24-hour scale completes the dive-ready aesthetic. The scratch-resistant sapphire crystal and solid case back round out the case construction.
Power comes from the Tag Heuer Calibre 7 automatic movement, based on the ETA 2892-A2 and housing 25 jewels. It beats at 28,800 vph and delivers a power reserve of approximately 46 hours. Functions include date, GMT, second time zone, hour, minute, and second.
The watch is secured on a stainless steel bracelet fastened by a folding clasp with push-button release. Swiss made and offered complete with its original box and papers, this is a capable and well-appointed sports watch built for serious water use.
