Frequently asked questions
What is the lug width of the Breitling Chronomat B01 42 AB01342B1O1S1?
The lug width of the Breitling Chronomat B01 42 AB01342B1O1S1 is 22 mm. This measurement is essential when selecting an aftermarket strap: any replacement strap must have a 22 mm attachment width, and ideally it should accommodate the pronounced lug curvature typical of this model.
What is the best strap for the Breitling Chronomat B01 42?
For the Chronomat B01 42, the most fitting options include alligator leather with a pronounced grain and matte finish, vegetable-tanned calf leather that develops a natural patina over time, or vulcanised rubber for sporting use. A NATO nylon strap is an excellent choice to reference the model's aeronautical heritage. The correct attachment width is 22 mm in all cases.
How do you change the strap on a Breitling Chronomat B01 42?
To replace the strap on the Chronomat B01 42, use a spring bar tool to release the spring bars securing the strap to the lugs. This can be carried out at home with care, or entrusted to a watchmaker or specialist atelier. It is advisable to use a tool with a plastic or nylon tip on the outer side of the lug to avoid scratching the stainless steel case.
Are there aftermarket straps compatible with the Breitling Chronomat B01 42 AB01342B1O1S1?

How long does a leather strap last on a Breitling Chronomat B01 42?
The lifespan of a leather strap depends on hide quality, tanning method, and daily care. A high-quality vegetable-tanned calf strap used regularly but not subjected to constant moisture or perspiration can last between two and five years while retaining a well-kept appearance. Top-grade alligator leather, owing to its density and scale structure, typically lasts even longer. MilanoStraps provides an 18-month guarantee against manufacturing defects on all straps.
