Strap for Navitimer Quartz 32 Stainless Steel - Red Gold / MOP / Bracelet

The Breitling Navitimer U77320E61A1U1 has a lug width of 16mm. This measurement is taken between the two lugs at their narrowest point and defines the exact strap width required for a correct fit. Using a strap of a different width will compromise both the aesthetics and the proper function of the keeper.

For the Navitimer U77320E61A1U1 in red gold and mother-of-pearl, a vegetable-tanned alligator strap in bordeaux, cognac or dark chocolate represents the most coherent choice given the piece's positioning. The alligator grain texture complements the complexity of the mother-of-pearl dial, while a deployant clasp extends the leather's lifespan by preventing fold marks at the pin hole.

To replace the strap on the Navitimer U77320E61A1U1, the spring bars securing the strap to the case lugs must be released. A curved spring bar tool is inserted into the side hole of each bar and gently levered to avoid scratching the red gold lugs. The operation takes approximately two minutes for an experienced hand; if in doubt, it is advisable to consult a watchmaker or atelier.

Yes: any strap with a 16mm attachment is technically compatible with the Navitimer U77320E61A1U1, provided the spring bars are standard. Milano Straps offers handcrafted 16mm straps in various materials — alligator, calf, shell cordovan, NATO — available bespoke or ready to ship, with finishes suited to both the steel and red gold elements of the case.

The lifespan of a leather strap depends on the quality of the hide, frequency of use and exposure to perspiration and environmental conditions. A high-grade vegetable-tanned alligator strap, with moderate daily use and proper care (avoiding prolonged moisture, applying leather conditioner periodically), typically lasts between three and five years. Using a deployant clasp reduces mechanical stress at the pin hole, noticeably extending the strap's service life.
