Frequently asked questions

What is the lug width of the Breitling Premier A37340351G1P1?

The lug width of the Breitling Premier A37340351G1P1 is 20mm. This measurement must be taken between the inner edges of the two lugs at the point where the strap attaches to the case. It is the critical figure for selecting a compatible strap that fits without lateral play or friction.

What is the best strap for the Breitling Premier A37340351G1P1?

For the stainless steel Breitling Premier A37340351G1P1, the most fitting choices are an alligator Mississippiensis strap with a brushed steel buckle or deployant clasp, a vegetable-tanned calf leather strap for a smart-casual register, or a shell cordovan strap for those seeking natural lustre and outstanding durability. The final choice depends on primary use: formal, business, or leisure.

How do you change the strap on a Breitling Premier A37340351G1P1?

The strap on the Breitling Premier A37340351G1P1 is replaced using a springbar tool. Insert the tip into the lug slot to compress the spring bars and slide the strap free. Care should be taken to avoid scratching the brushed-and-polished steel case. Alternatively, any watchmaker or the Casati Milano atelier can perform the swap by appointment.

Are there aftermarket straps compatible with the Breitling Premier A37340351G1P1?

Yes: any strap with a 20mm lug width is compatible with the Breitling Premier A37340351G1P1, provided that measurement is exact. Milanostraps.it offers a curated selection of handcrafted 20mm straps in various leathers and finishes, designed to fit this class of timepiece without adapters or modifications.

How long does a leather strap last on the Breitling Premier A37340351G1P1?

The lifespan of a leather strap depends on the quality of the hide and how the wearer cares for it. A high-grade alligator or shell cordovan strap, worn regularly but not daily, typically lasts between three and five years whilst retaining its shape and grain. Vegetable-tanned leather develops a natural patina but should be kept away from prolonged moisture. The 18-month production defect warranty offered by Casati Milano provides added peace of mind from the outset.
