FAQ

What is the lug width of the Breitling Premier A13315351B1X1?

The lug width of the Breitling Premier A13315351B1X1 is 20mm. This measurement should be taken with a digital calliper directly between the case lugs to ensure correct compatibility with any aftermarket strap.

What is the best strap for the Breitling Premier A13315351B1X1?

For the stainless steel Premier A13315351B1X1, an alligator strap in black or midnight blue with hornback grain is the most coherent choice given the model's elegant-sports character. Alternatively, a vegetable-tanned calf leather strap in tobacco brown develops a patina over time that complements the dial tones. For a more casual look, a NATO nylon strap references the Premier's aeronautical origins.

How do I change the strap on the Breitling Premier A13315351B1X1?

To replace the strap on the Premier A13315351B1X1, a dedicated springbar tool is required to remove the spring bars from the case lugs. Work on a soft surface to protect the case finishing and ensure the new spring bars have the correct diameter for the 20mm lugs. If in doubt, the operation can be carried out by a watchmaker or at the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling Premier A13315351B1X1?

Yes, any strap with a 20mm lug width is dimensionally compatible with the Breitling Premier A13315351B1X1. Milanostraps.it offers a selection of handcrafted straps in various leathers and materials, all produced in the correct lug size. It is important to verify that the strap end is appropriately shaped to follow the curve of the Premier's lugs.

How long does a leather strap last on a Breitling Premier A13315351B1X1?

The lifespan of a leather strap depends on the material, frequency of use and conditions of wear. A high-quality vegetable-tanned alligator strap worn daily under normal conditions typically lasts between 2 and 4 years. Calf leather has a similar lifespan but is more susceptible to moisture. Avoiding prolonged contact with water and perspiration significantly extends the strap's life. Casati Milano straps carry an 18-month warranty against manufacturing defects.
