Breitling Navitimer 1 35 Automatic Red Gold R17395211A1P1

It keeps the Navitimer's circular slide-rule bezel without a chronograph, in a case 35 mm across and 9.92 mm thick that takes an 18 mm strap. Inside is the self-winding Breitling Caliber 17, a COSC-certified chronometer with about 38 hours of power reserve, and the case is water-resistant to 30 m.

The same red gold and mother-of-pearl watch comes with a folding clasp as R17395211A1P2 and on a red gold bracelet as R17395211A1R1. The U17395211A1P3 pairs steel with red gold on the same strap and buckle, and the A17395211A1P5 is the all-steel version. The Navitimer 1 Chronograph 41 (A13324121B1P1) is 41 mm and 14.44 mm thick, so the 35 wears far slimmer.
