Frequently asked questions

What is the lug width of the Breitling Premier R37340351G1P1?

The lug width of the Breitling Premier R37340351G1P1 is 20mm. This measurement refers to the internal distance between the two lugs on the red gold case and determines the correct strap size. For an accurate reading, use a digital calliper placed inside the lugs, parallel to the case.

What is the best strap for the Breitling Premier R37340351G1P1 in red gold?

For the red gold version of the Premier, an alligator strap with vegetable tanning in warm tones such as cognac, bordeaux or dark brown is the most fitting choice. Shell cordovan in a smooth finish is a refined alternative for those seeking a more compact surface. In both cases, a red gold buckle or deployant clasp ensures full metallic coherence across the watch.

How do I change the strap on the Breitling Premier R37340351G1P1?

To replace the strap on the Breitling Premier R37340351G1P1, the spring bars securing the strap to the case lugs must be removed using a dedicated spring bar tool or a forked screwdriver. When working on a red gold case, use a soft surface to prevent scratches. For a safe installation, it is advisable to consult a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling Premier R37340351G1P1?

Yes. The 20mm lug width of the R37340351G1P1 is a widely adopted standard, ensuring broad availability of high-quality aftermarket straps. On milanostraps.it you will find a curated selection of 20mm straps in alligator, calf leather, shell cordovan and rubber, all handcrafted and compatible with the original Breitling case lugs.

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

The lifespan of a leather strap depends on the quality of the tanning, the thickness and the conditions of use. A premium vegetable-tanned alligator strap, cared for properly and kept away from moisture and perspiration, can last between three and six years while retaining an impeccable appearance.
