FAQ

What is the lug width of the Breitling Premier A45340241B1P1?

The lug width of the Breitling Premier A45340241B1P1 is 20mm. This measurement is taken with a digital calliper positioned internally between the two lugs, flush with the case bezel, excluding any lateral protrusions.

What is the best strap for the Breitling Premier A45340241B1P1?

For the Premier A45340241B1P1, a vegetable-tanned alligator strap is the most coherent choice given the watch's formal-sport character. The bombé belly grain complements the case's mixed finishes. Alternatively, smooth calf or shell cordovan develop a distinguished patina over time. For active use, vulcanised rubber provides comfort and moisture resistance.

How do you change the strap on a Breitling Premier A45340241B1P1?

The strap is removed using a fine-tipped springbar tool, carefully levering out the spring bars lodged within the 20mm lugs. Care must be taken not to scratch the satin-finished case surfaces. For the first replacement, it is advisable to consult a watchmaker or a specialist atelier.

Are there aftermarket straps compatible with the Breitling Premier A45340241B1P1?

Yes, any strap with a 20mm attachment width is compatible with the Breitling Premier A45340241B1P1. Milano Straps offers a curated selection of handcrafted straps in alligator, calf, shell cordovan, NATO weave and rubber, all verified at 20mm and available with buckle or deployant clasp.

How long does a leather strap last on a Breitling Premier A45340241B1P1?

The lifespan of a leather strap depends on the material, tanning method and frequency of wear. A quality vegetable-tanned alligator strap, rotated with a second strap, can last between three and six years while developing a distinguished patina. Shell cordovan offers superior surface abrasion resistance. Prolonged contact with water and perspiration should be avoided; a deployant clasp is recommended to reduce mechanical stress on the leather.
