Blancpain Fifty Fathoms Bathyscaphe Chronograph - 43.6mm (2023)

Description:

The Blancpain Fifty Fathoms Bathyscaphe Chronographe Flyback ref. 5200-0153-NABA is a striking all-ceramic dive chronograph that makes an immediate visual statement. Its 43.6 mm satin-brushed black ceramic case is crowned by a unidirectional rotating bezel set with a vivid green ceramic insert, featuring a Liquidmetal™ 60-minute scale and luminous starting point — a seamless green-on-green aesthetic from bezel to sunburst dial. The bold green sunburst dial is populated with luminous grey hands and applied circle and stick hour markers, three chronograph sub-dials, and a date display positioned between 4 and 5 o'clock. A sapphire crystal with anti-reflective treatment and a transparent case back showcase both dial and movement, while the screw-down crown ensures the watch's formidable 300-metre water resistance.

Beating at the heart is Blancpain's in-house Calibre F385, operating at a high-frequency 5 Hz (36,000 vph) for 1/10th second chronograph precision. The flyback function allows the chronograph to be instantly reset and restarted with a single push of the pusher — indispensable for timing consecutive events. The movement is composed of 322 parts, 37 jewels, and incorporates a silicon balance spring for superior magnetic resistance and long-term precision, backed by a 50-hour power reserve. The watch is presented on a black NATO strap secured with a ceramic pin buckle, lending it a robust yet refined sporting character.

This piece presents as a full set with box and papers, circa 2023.
