Strap for Premier B01 Chronograph 42 Red Gold / Silver / Alligator

The lug width of the Breitling Premier RB0118371G1P1 is 22mm. This measurement should be taken with a vernier calliper at the innermost point of the lugs, where the strap meets the case. The tail of the strap is typically 20mm wide to ensure correct alignment on the buckle.

For the 18k red gold version, the most coherent choice is a Mississippi alligator strap in dark brown or chocolate, paired with a matching red gold buckle. Alternatively, a shell cordovan in bordeaux or a vegetable-tanned calfskin in cognac develops a warm patina that complements the red gold tones without overwhelming them.

The strap is replaced by releasing the spring bars connecting it to the case lugs. A spring bar tool — either a forked or pointed type — is used to compress the spring bars and slide the strap free. It is advisable to work on a soft mat to avoid scratching the red gold case. No brand-specific tools are required and the operation takes only a few minutes.

Yes. Any strap with a 22mm lug end and a 20mm tail is technically compatible with the Breitling Premier RB0118371G1P1, provided the spring bars fit the standard internal lug width of approximately 20mm. Milano Straps offers a curated selection of handcrafted 22mm straps in alligator, calfskin and shell cordovan, with the option to customise the buckle material.

Longevity depends on the material and frequency of use. A quality alligator strap, when rotated with other watches, typically lasts 2 to 4 years before showing significant wear. Vegetable-tanned calfskin develops a pleasing patina over time but is more susceptible to moisture. Shell cordovan is the most resistant to deformation and can last over 5 years with basic maintenance. Casati Milano provides an 18-month guarantee against manufacturing defects.
