Rooted in Breitling's professional instrument tradition, the Colt reference A1738811/BD44 pairs a round 44mm stainless steel case with a custom diamond-set bezel — a combination that sets this particular example apart from the standard line. Scratch-resistant sapphire crystal protects the black dial, which features luminescent hour markers and matching luminescent hands for consistent legibility in varying light conditions. A date display sits at the 3 o'clock position, rounding out the practical layout.
Inside, the watch runs on the Caliber 17, a movement based on the ETA 2824-2 and carrying Swiss Made designation. Water resistance reaches 200 meters (660 feet), making the piece capable across swimming, snorkeling, and professional marine use. The stainless steel bracelet completes the build, keeping the overall profile consistent with the Colt's sports-tool character.
This is a used, customized example offered without original box or papers. The diamond bezel adds a luxury dimension to an otherwise purpose-driven design, giving the watch a presence that moves comfortably between active and dressed-up settings.
