Strap for Premier Heritage B21 Chronograph Tourbillon Red Gold / Red / Japan

For an 18-carat red gold case such as that of the Premier RB21202A1K1P1, a vegetable-tanned alligator strap in burgundy, tobacco or dark brown tones is the most aesthetically coherent choice. A deployant clasp in red gold completes the pairing while preserving chromatic symmetry.

Strap replacement on the Breitling Premier RB21202A1K1P1 is carried out using standard 20mm spring bars. A flat-tipped spring bar tool is sufficient to remove the bars from the lug holes and swap the strap in a matter of minutes, without any intervention on the watch itself.
