Breitling Navitimer B01 Chronograph 43 Ice Blue Watch AB0138241C1P1

The Breitling Navitimer B01 Chronograph 43 in Ice Blue, reference AB0138241C1P1, is a modern take on the pilot’s chronograph first introduced in 1952. Willy Breitling developed the original with a circular slide rule so pilots could carry out flight calculations from the wrist, and in 1954 the Aircraft Owners and Pilots Association (AOPA) adopted it as its official watch. Over the decades it was worn by airline captains, aviation enthusiasts and public figures, and it has remained one of Breitling’s most recognised models.

This version keeps the classic Navitimer layout with a few refinements. The slide rule is flatter and the sapphire crystal is domed, which gives the watch a slimmer look on the wrist. Polished and brushed surfaces alternate across the case, and the AOPA wings are back at 12 o’clock, where they sat on early models. The Ice Blue dial is part of the newer colour range, and a date aperture sits on the dial. The bidirectional bezel carries the slide rule.

Inside is the Breitling 01 manufacture calibre, a self-winding chronograph movement with 47 jewels, a 28,800 vph beat rate and a power reserve of approximately 70 hours. The chronograph records 1/4 seconds, 30 minutes and 12 hours. The screw-in caseback is sapphire crystal, so the movement is visible from the back of the watch.

The stainless steel case measures 43mm in diameter and 13.69mm thick, with a 22mm lug width. The cambered sapphire crystal is glareproofed on both sides, the crown is non screw-locked with two gaskets, and water resistance is 3 bar (30m / 99ft). It comes on a black alligator leather strap that tapers from 22mm to 18mm, fitted with a stainless steel folding clasp.
