Strap for Navitimer B01 Chronograph 43 Red Gold / Starlux

The Breitling Navitimer RB01386A1G1P1 features 22mm lugs. This measurement refers to the internal distance between the two case lugs, i.e. the width the strap must measure at the attachment point. To confirm the measurement on your own piece, it is advisable to use a digital calliper placed between the inner surfaces of the lugs.

For the steel Navitimer RB01386A1G1P1, the most suitable choices are vegetable-tanned calfskin for versatile everyday wear, smooth-belly alligator for formal occasions, and technical nylon NATO to reference the model's aeronautical origins. A steel pin buckle or a deployant clasp completes the pairing in a manner consistent with the watch's instrumental character.

The strap on the Navitimer RB01386A1G1P1 is removed using a fine-tipped spring bar tool, inserted into the lateral hole of the lug to compress the spring bar and release the strap. No professional tools are required, though it is advisable to work on a soft surface to protect the polished case surfaces. The new strap is fitted by snapping the spring bar into position.

Yes, any strap with a 22mm attachment width is compatible with the Navitimer RB01386A1G1P1. Milano Straps offers a selection of Italian artisan straps in 22mm, crafted from materials such as Tuscan calfskin, alligator and technical nylon, all compatible with the original Breitling lugs without the need for adapters.

The lifespan of a leather strap depends on the quality of the hide, daily use and maintenance. A high-quality calfskin or alligator strap, with regular use, typically lasts between two and four years. Avoiding prolonged contact with water and perspiration, and occasionally applying a leather conditioner, will significantly extend the strap's service life.
