Strap for Chronomat B01 42 Giannis Antetokounmpo Unique Piece

The lug width of the Breitling Chronomat B01 42 RB01344A1L2R1 is 22mm. This measurement refers to the internal distance between the lugs where the strap is fitted. To verify it on your own piece, use a digital calliper placed between the lugs in contact with the case middle.

For the red gold version of the Chronomat B01 42, the most suitable materials are vegetable-tanned alligator — preferably in burgundy, chocolate brown or matte black — and hand-burnished calfskin. Shell cordovan is a refined alternative for those who appreciate a natural patina developing over time. In all cases, the correct lug width to fit is 22mm, with a recommended taper to 20mm or 18mm at the keeper.

The strap on the Chronomat B01 42 is secured by standard 1.5mm spring bars. To replace it, use a spring bar tool with a forked tip to release the bars from the lugs and fit the new strap. The operation does not require a watchmaker, but care should be taken when working on a red gold case to avoid scratching the finished surfaces.

The lifespan of a leather strap depends primarily on the quality of the hide, the tanning method and daily use. A high-quality vegetable-tanned alligator strap, with proper care — avoiding prolonged contact with water and perspiration, and conditioning every 2 to 3 months — can last between 3 and 7 years. Milano Straps provides an 18-month guarantee covering manufacturing defects on all its straps.
