Strap for Navitimer B01 Chronograph 43 Stainless Steel - Red Gold / USA

The lug width of the Breitling Navitimer UB01384A1B1P1 is 22 mm. This measurement is taken internally between the two lugs using a millimetre calliper. It is essential to use this exact measurement when selecting an aftermarket strap to ensure correct fitment without forcing or lateral play.

For the red gold and steel variant, a cognac or honey alligator strap in vegetable-tanned leather is the most aesthetically coherent choice: the scale texture complements the warmth of the metal without overwhelming the dial. Alternatively, natural Tuscan calf leather or burgundy shell cordovan offer more understated yet equally refined options. For sporting use, vulcanised rubber provides durability and water resistance.

The strap on the Navitimer UB01384A1B1P1 is removed using a flat-tip or forked spring bar tool inserted into the lateral slot of the 22 mm spring bars. It is advisable to work on a soft surface to protect the case. The replacement does not require professional tools, but care should be taken to avoid scratching the lugs, particularly on the red gold-finished version.

Yes. Any strap with a 22 mm attachment and standard spring bars is compatible with the Navitimer UB01384A1B1P1.

The lifespan of a leather strap depends on the quality of the hide, maintenance habits, and frequency of wear. A high-quality alligator or calf leather strap, rotated with other straps and kept away from excessive moisture, can last between three and six years while maintaining structural integrity and aesthetic appeal. Milano Straps straps carry an 18-month warranty against manufacturing defects.
