Strap for Chronomat 44 Stainless Steel / Diamond / Carbon Black / Croco

The lug width of the Breitling Chronomat B01 44 AB011053.M524.743P is 22 mm. This measurement is taken between the two case lugs using a millimetre calliper held perpendicular to the lugs. Any 22 mm strap will be compatible with this reference.

The most suitable straps for the Chronomat B01 44 are: vegetable-tanned alligator for formal settings, boxy calf leather for versatile daily wear, vulcanised rubber for sport use, and ballistic nylon NATO to reference the model's military heritage. The choice depends on intended use and aesthetic preference. Milano Straps offers all these options in 22 mm.

To replace the strap on the Breitling Chronomat B01 44, you will need a spring bar tool. Insert the tip into the slot on the side of the lug, compress the spring bar and slide the strap free. Care must be taken to avoid scratching the case. If in doubt, it is advisable to entrust the operation to a watchmaker or to the Casati Milano atelier.

The lifespan of a leather strap depends on material quality, care and use.

Milano Straps provides an 18-month warranty against manufacturing defects. Regular conditioning with a leather cream will significantly extend the strap's life.
