To replace the strap on the Breitling Montbrillant AB013012.G709.718P, use a 1.5 mm fine-tip spring bar tool. Insert the tool into the lateral hole of the lug, compress the spring bar and slide the strap out. Work on a soft surface to protect the case. The original spring bar (1.8 mm diameter) can be reused with the new strap.

The lifespan of a leather strap depends on the material and usage habits. A quality vegetable-tanned box-calf strap typically lasts 2–4 years with daily wear, developing a characteristic patina over time. Shell cordovan may exceed 5 years due to its dense fibre structure. Frequent exposure to water or perspiration significantly reduces longevity; in such cases it is advisable to alternate with a rubber or NATO strap.
