Breguet
Tradition 7027BB/G9/9V6— lug 20mm

The Breguet Tradition 7027BB/G9/9V6 is fitted with a 20 mm lug width. To verify aftermarket strap compatibility, measure the internal distance between the two lugs at the point of contact with the case using a caliper, ensuring the measurement corresponds exactly to 20 mm.

For the white gold case and skeletonized dial of the caliber 507DR, an alligator strap with vegetable tanning—preferably in midnight blue or slate grey tones—represents the most coherent pairing with the Haute Horlogerie aesthetic of the piece. Box calf leather is an excellent alternative for those who prefer smooth surfaces and formal refinement.

Strap replacement is accomplished using standard 20 mm spring bars housed in the case lugs. A dedicated spring bar tool is required to compress the bars and remove the strap. It is recommended to work on a soft surface to protect the white gold case from accidental scratches.

Yes, any strap with a 20 mm lug width and standard spring bars is compatible. Milano Straps offers a selection of artisanal 20 mm straps in various materials—alligator, calf, rubber—designed to match both aesthetically and dimensionally the 37 mm Breguet Tradition references.

The lifespan of a leather strap depends on the quality of the tanning and conditions of use. A high-quality vegetable-tanned alligator strap, with regular but not extreme use, maintains structural and aesthetic integrity for 2-4 years. Moisture is the primary threat: it is advisable to avoid prolonged water contact and periodically apply a conditioner formulated for fine leather.
