Breitling
Premier A37340351B1P1— lug 20mm

The Breitling Premier A37340351B1P1 has a lug width of 20mm at the upper attachment point. This measurement should be taken with a digital calliper inserted between the lugs, not across the outer surface. Some tapered straps narrow to 18mm at the lower attachment, which enhances the elegance of the overall profile.

For the Premier A37340351B1P1, an alligator strap with vegetable tanning is the most coherent choice given the line's aesthetic: the belly grain complements the geometric character of the stainless steel case. Smooth box-calf leather offers the most versatile alternative, while a cordura NATO or vulcanised rubber strap suits more active or informal settings without undermining the model's character.

The strap on the Breitling Premier A37340351B1P1 is secured by standard 20mm spring bars. To replace it, use a spring bar tool or a thin flat-head screwdriver: compress the spring bar towards the inside of the lug, slide out the existing strap and fit the new one. The operation can be carried out independently or by a watchmaker to avoid any risk of scratching the case.

Yes, any strap with a 20mm lug width is technically compatible with the Breitling Premier A37340351B1P1. Milano Straps offers a curated selection of handcrafted leather, NATO and rubber straps specifically suited to this lug size. It is advisable to select straps supplied with spring bars and with a tail end profile compatible with the Premier's lug geometry.

The lifespan of a leather strap depends on the quality of the hide, the tanning process and daily wear conditions. A high-quality alligator or calf leather strap with vegetable tanning, kept away from excessive moisture and perspiration and stored correctly, can last between two and five years of regular use. Casati Milano provides an 18-month guarantee against production defects on all its handcrafted straps.
