Strap for Premier Automatic 40 Stainless Steel / Silver / Nubuck Anthracite / Folding

The lug width of the Breitling Premier A37340351G1X1 is 20 mm. This measurement should be taken with a digital calliper positioned between the two parallel lugs, flush against the case, to obtain an accurate reading rather than relying on visual estimation.

For the Breitling Premier A37340351G1X1, the most suitable materials are vegetable-tanned calf leather for everyday and business wear, alligator belly or hornback for formal and evening occasions, and shell cordovan for those seeking a leather that develops a deep patina over time. The standard configuration is a 20 mm straight end at the lug tapering to 18 mm at the buckle.

To replace the strap on the Breitling Premier A37340351G1X1, a double-tipped springbar tool is required. Insert the tool into the gap between the lug and the strap, compress the springbar and slide the strap out. Care should be taken to avoid scratching the steel lugs; it is advisable to protect the case with a soft cloth before proceeding.

The lifespan of a leather strap depends on the quality of the tanning process and daily usage. A quality vegetable-tanned calf strap has an average life of 12 to 24 months with daily wear; alligator or shell cordovan, owing to the density of their fibres, can exceed 3 to 4 years when properly maintained with natural conditioners and protected from excessive moisture. Casati Milano offers an 18-month warranty against manufacturing defects.
