Strap for Chronomat 44 Stainless Steel / Rose Gold / Diamond / Antarctica White / Bracelet

The lug width of the Breitling Chronomat B01 44 CB011053.A696.375C is 22mm. This measurement refers to the internal distance between the two lugs of the case, where the strap is fitted via spring bars. It is essential to respect this measurement to ensure a correct fit and aesthetically proportionate result.

For the Chronomat B01 44 in rose gold and steel, the most suitable options are alligator leather with vegetable tanning for formal contexts — in Hornback grain in tobacco or black — and Tuscan pull-up calf leather for everyday wear. Vulcanised rubber is preferable for sporting or aquatic environments. In all cases, the width must be 22mm to respect the proportions of the 44mm case.

The strap on the Chronomat B01 44 is removed using a spring bar tool: insert the tip into the small slot on the side of the lug, compress the spring bar and slide out the strap. The operation requires care to avoid scratching the steel and rose gold case. It is advisable to consult a watchmaker or the Casati Milano atelier for the first replacement, particularly when working with polished finishes.

Yes, any strap with a standard 22mm fitting is compatible with the Breitling Chronomat B01 44 CB011053.A696.375C, provided it uses 1.5mm diameter spring bars. Milano Straps offers a selection of artisan 22mm straps made in Italy, with bespoke customisation available through the Casati Milano atelier. The recommended standard length is 115/75mm.

The lifespan of a leather strap depends on the quality of the tanning, daily use and maintenance. An artisan-quality alligator or vegetable-tanned Tuscan calf strap, rotated with other straps, can last between 3 and 5 years while retaining its structure and patina. Milano Straps offers an 18-month guarantee against manufacturing defects. Prolonged contact with water and perspiration should be avoided to preserve the leather fibres.
