Strap for Cosmonaute

The Breitling Navitimer A2232212/B600 has a lug width of 22 mm. This measurement is taken internally between the two lugs of the case and is compatible with all standard 22 mm aftermarket straps.

For the Navitimer A2232212/B600, the most coherent choices with the instrument-grade nature of the watch are: hornback alligator leather for an elegant pairing, vegetable-tanned Tuscan calfskin for an authentic patina, or a ballistic nylon NATO strap to preserve the tool-watch character. A brushed steel deployant clasp is recommended for those seeking chromatic continuity with the case.

Strap replacement requires a spring bar tool or lever-type screwdriver. The 22 mm spring bars are compressed laterally to release the lugs. It is advisable to work on a soft surface to protect the crystal and case, or to entrust the operation to a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 22 mm lug width and standard length (approximately 120/75 mm) is compatible. Milano Straps offers a curated selection of handcrafted leather, NATO and rubber straps specifically sized for the Navitimer, with ardillon buckles or deployant clasps in steel to match the original case.

Longevity depends on leather type and usage: a vegetable-tanned calfskin strap typically lasts 2–4 years with daily wear, developing a distinctive patina over time. Alligator leather, owing to its dense fibre structure, can exceed 5 years if kept away from excessive moisture and perspiration. Milano Straps straps carry an 18-month warranty against manufacturing defects.
