With the flyback chronograph allowing instantaneous restarting with a single push of a button and the legible, contrasting dial, this is a true member of the Fifty Fathoms collection in terms of being the perfect companion underwater. Water resistant to 300m, the satin-brushed black ceramic 43.60mm case features sapphire crystal back and bezel with ceramic fill, Liquidmetal indication and luminous dot at 12 o'clock. Nested inside is the self-winding F385 with 50-hour power reserve and 37 jewels, fitted with silicon balance-spring. The sunburst black dial with luminescent hour markers and hour and minute hands along with red-tipped flyback chronograph seconds hand offers great legibility. It displays date in an aperture as well as sub-dials for seconds, 30-minute counter and 12-hour counter. The black sail-canvas strap is secured on the wrist with a tang clasp.
