Breitling Superocean A17040 41.5 mm

The Colt Superocean A17040 is a 41.5 mm stainless-steel diver with the purposeful proportions of a late professional tool watch. A unidirectional bezel and screw-locked crown support its formidable 1,000-metre water resistance, while the 15 mm case gives the watch the physical authority expected of a deep-rated instrument. Its restrained time-and-date layout stays immediately legible without adding a chronograph's visual density.

Breitling Calibre 17 is an automatic movement based on the ETA 2824-2. It beats at 4 Hz, uses a bidirectional rotor, contains 25 jewels and provides a 38-hour reserve. The date is its sole calendar complication, and hacking seconds allow the balance to stop when the crown is pulled. The result is a straightforward mechanism matched to the watch's practical brief.
