Strap for Navitimer 8 Automatic Day & Date 41 Stainless Steel / Blue / Black Calf / Pin

The lug width of the Breitling AVI A45330101C1X1 is 21 mm. This is an atypical dimension within the sport-heritage segment. To maintain the correct visual proportions with the case lugs, only straps measuring exactly 21 mm at the attachment point should be used.

For the Breitling AVI A45330101C1X1, the most appropriate materials given its avionic character are vegetable-tanned calfskin with a military grain, Mississippiensis alligator in a bombed finish for formal settings, and Horween shell cordovan for those who appreciate a developing patina. Vulcanised rubber is the practical choice for intensive or summer use.

Remove the strap using a T-tip or blade-style spring bar tool inserted into the lug slot to compress the spring bars. Work on a soft surface to protect the case. Breitling's original spring bars have a 1.5 mm diameter; check their integrity before fitting a new 21 mm strap.

Yes. Aftermarket straps with a 21 mm lug width tapering to 18 or 19 mm at the buckle are compatible with the Breitling AVI A45330101C1X1. Milano Straps offers a curated selection of handcrafted straps in various materials, specifically sized for this lug width, available with a standard buckle or stainless steel deployant clasp.

Leather strap longevity depends on the material and frequency of wear. A quality vegetable-tanned calfskin strap typically lasts 18 to 36 months with regular use; alligator, owing to its scale structure and tanning process, can exceed three to four years. Shell cordovan is the most resistant to deformation at the fold point. Periodic conditioning with a neutral cream significantly extends strap life.
