Strap for Premier Heritage B21 Chronograph Tourbillon Red Gold / Beige - Rainbow

The lug width of the Breitling Premier RB21205A1G1P1 is 20mm. This measurement is taken with a digital calliper at the inner distance between the two lugs at the bottom of the case, where the strap fits. Any 20mm strap is compatible with this reference.

For an 18k red gold case such as that of the Premier RB21205A1G1P1, a glossy alligator strap in cognac or bordeaux tones represents the most coherent choice with the watch's aesthetic identity. Alternatively, shell cordovan in dark brown or hand-burnished calfskin in tobacco offer a more personal character, developing a distinguished patina over time.

The strap on the Breitling Premier RB21205A1G1P1 is removed using a fine-tip spring bar tool or a thin flat-head screwdriver, carefully depressing the spring bars connecting the strap to the lugs. Care should be taken not to scratch the red gold case; it is advisable to protect the lugs with masking tape before proceeding.

Yes. Any 20mm strap with straight ends is compatible with the Breitling Premier RB21205A1G1P1.

The lifespan of a leather strap depends on the quality of the tanning, daily use and care. An alligator or shell cordovan strap with vegetable tanning, rotated with other straps and kept away from excessive moisture, can last between three and five years whilst retaining a distinguished texture. Regular treatment with natural wax and prompt replacement of stitching can significantly extend its useful life.
