The Heritage

The Breitling Premier Automatic 40 Stainless Steel A37340351C1X2 belongs to a line created as a direct tribute to Breitling's 1940s production, designed for urban and discerning clients away from the aviation world. The 40mm stainless steel case features balanced proportions with a rounded silhouette recalling classic dress watch forms. The silvered dial with applied indices and leaf-shaped hands ensures immediate readability. The Breitling Caliber 37 automatic movement powers hours, minutes, small seconds at 6 o'clock, and date. The 20mm lug width accommodates standard straps in leather, rubber, and other materials without interchangeability with adjacent sizes.

FAQ

What is the lug width of the Breitling Premier A37340351C1X2?

The lug width of the Breitling Premier A37340351C1X2 is 20mm. This measurement corresponds to the internal distance between the two lugs at the strap attachment point and must be respected precisely to ensure a correct aesthetic and functional pairing.

What is the best strap for the Breitling Premier A37340351C1X2?

For the Breitling Premier A37340351C1X2, a vegetable-tanned alligator strap in 20mm is the most coherent choice with the watch's sartorial character. Smooth vegetable-tanned calf leather is the most versatile alternative for daily use, developing a personal patina over time. Both complement the silver dial and stainless steel case perfectly.

How do you change the strap on the Breitling Premier A37340351C1X2?

To replace the strap on the Breitling Premier A37340351C1X2, a spring bar tool is required to remove the spring bars connecting the strap to the lugs. Insert the tool tip into the spring bar slot, compress it and slide it out laterally. Care must be taken not to scratch the stainless steel lugs. If in doubt, a watchmaker or the Casati Milano atelier can carry out the replacement.

Are there aftermarket straps compatible with the Breitling Premier A37340351C1X2?

How long does a leather strap last on the Breitling Premier A37340351C1X2?

The lifespan of a leather strap for the Breitling Premier A37340351C1X2 depends on the material and maintenance.
