Breguet
Classique 7147BB/29/9WU— lug 18mm

The Breguet Classique 7147BB/29/9WU is fitted with lugs that measure 18mm in width at the root, measured internally between the two lugs at the point of contact with the case. This is the measurement to specify when purchasing a compatible replacement strap.

For a white gold case with guillochage dial, a strap in belly alligator with fine grain or vegetable-tanned calf leather represents the choice most consistent with the model's neoclassical aesthetic. Tobacco brown, midnight blue, or matte black colors coordinate most effectively with the blued pomme hands and cool tone of the white gold.

The strap is removed using a flat-tip spring bar tool or thin-blade screwdriver, carefully prying the spring bar that connects the strap to the lugs. Given the delicate nature of the white gold lugs and the case's reduced thickness, it is recommended to entrust this operation to a watchmaker or use a tool with a plastic tip to avoid scratching.

Yes. Any 18mm strap with straight ends and heel thickness not exceeding 3.5mm is technically compatible with the Breguet Classique 7147BB/29/9WU. Milano Straps offers a selection of artisanal 18mm straps made specifically for classic watches with thin lugs, available in alligator, calf, nylon, and vulcanized rubber.

The average lifespan of a quality leather strap — alligator or vegetable-tanned calf — ranges from 18 to 36 months with regular daily use, provided prolonged exposure to water and perspiration is avoided. Rotating between two or three straps significantly extends the life of each one. Milano Straps straps are covered by an 18-month warranty against manufacturing defects.
