Breitling
Premier R37340351G1P1— lug 20mm

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.

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.

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.
