Strap for Cosmonaute

The Breitling Navitimer D2232212/B657 features a lug width of 22 mm. This measurement is standard across the larger-diameter Navitimer references (41.5 mm case) and determines compatibility with any aftermarket strap. It is advisable to verify the measurement using a digital calliper placed internally between the lugs before purchasing a replacement strap.

For the D2232212/B657 in steel and yellow gold, the most suitable straps are: alligator belly in cognac or honey tones to complement the warm gold hues, vegetable-tanned calf leather in tobacco for a natural patina over time, vulcanised rubber for sporting use, and shell cordovan in burgundy or moss green for an exceptional choice. A deployant clasp in yellow gold or brushed steel is the recommended fastening.

To replace the strap on the Navitimer D2232212/B657, the spring bars must be removed using a dedicated spring bar tool with a forked tip. The Navitimer's lugs feature a pronounced curve: it is essential that the new strap has curved ends to sit flush against the case profile. The operation can be carried out independently with the correct tools or entrusted to a watchmaker or the Casati Milano atelier.

Yes, numerous aftermarket straps are compatible with the Breitling Navitimer D2232212/B657, provided they measure 22 mm at the lug and feature curved ends suited to the case profile. Milano Straps offers a selection of handcrafted straps in leather, alligator, shell cordovan and rubber, specifically sized for this width, with the option of customised ends upon request.

The lifespan of a leather strap depends on material quality, frequency of use and exposure to perspiration and moisture. A quality calf leather strap has an average lifespan of 12 to 24 months with daily wear; alligator or shell cordovan, being denser and more resilient materials, can last between 3 and 5 years with proper care. Milano Straps straps are covered by an 18-month guarantee against manufacturing defects.
