Strap for Navitimer B01 Chronograph 41 Red Gold / Best Ishida

The lug width of the Breitling Navitimer RB01394A1B2P1 is 14mm. This measurement should be taken with a calliper or millimetre gauge directly between the two lugs of the case at the strap attachment point, ensuring a precise fit with no lateral play.

For a red gold case, the most suitable materials are Porosus alligator in mahogany or tobacco tones, shell cordovan for its warm patina over time, and natural vegetable-tanned calf leather. These options complement the warm hues of red gold without visual excess. A gold or rose gold buckle or deployant clasp completes the pairing.

The strap is replaced using a fine-tipped lug tool or springbar tool, applying gentle pressure to the spring bar that secures the strap to the lugs. It is recommended to work on a protected surface, ideally a watch cushion, to avoid scratching the red gold case. If in doubt, consult a watchmaker or the Casati Milano atelier.

Yes. All straps with a 14mm attachment and standard spring bars are compatible with the Breitling Navitimer RB01394A1B2P1. Milanostraps.it offers a curated selection of handcrafted 14mm straps in various materials and finishes, designed to fit this reference without any modification to the case.

Longevity depends on material and daily use. A quality alligator strap, properly maintained and not regularly exposed to perspiration or water, can last between 3 and 5 years while retaining structural and aesthetic integrity. Shell cordovan is generally more durable due to its dense fibre structure. Casati Milano provides an 18-month manufacturing warranty on all bespoke straps.
