The lug width of the Breitling Chronomat B01 44 IB011012/G687 is 22mm. This measurement is consistent across the entire Chronomat B01 44 family and determines compatibility with any aftermarket or replacement strap.

What is the best strap for the Breitling Chronomat B01 44 IB011012/G687?

For the two-tone steel and rose gold version such as the IB011012/G687, straps in bordeaux or cognac alligator with contrast stitching complement the warm tones of the rose gold case. Alternatively, a polished-finish calfskin strap or a two-tone nylon NATO preserve the model's original sporting character.

How do you change the strap on the Breitling Chronomat B01 44 IB011012/G687?

The strap on the Chronomat B01 44 is replaced by removing the spring bars from the lugs using a dedicated springbar tool. The integrated rider tabs on the bezel do not interfere with the operation.

How long does a leather strap last on a Breitling Chronomat B01 44?
