FAQ

What is the lug width of the Breguet Tradition 7097BB/GY/9WU?

The Breguet Tradition 7097BB/GY/9WU is fitted with an 18mm lug width. To verify this, measure with a digital caliper the distance between the two case lugs at the spring bar position: the correct value is exactly 18mm.

What is the best strap for the Breguet Tradition 7097BB/GY/9WU?

For the white gold case of the 7097BB/GY/9WU, a slate grey or anthracite alligator belly strap is the most coherent choice: the natural texture of the scales complements the guilloché surfaces of the movement, and the color echoes the original dial palette. Polished black box calf is the universal formal alternative.

How do you change the strap on the Breguet Tradition 7097BB/GY/9WU?

Strap replacement requires a spring bar tool with a fine tip. The lugs on the Tradition are slender, so a thin instrument is recommended to avoid scratching the white gold case. If you lack experience, it is advisable to consult a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Breguet Tradition 7097BB/GY/9WU?

Yes: any strap with an 18mm attachment is technically compatible. Milano Straps offers a selection of artisanal leather, rubber, and nylon straps specifically designed for 18mm lugs, with custom finishing that replicates the curve of Breguet lugs for a perfect fit.

How long does a leather strap last on a Breguet Tradition 7097BB/GY/9WU?

A quality leather strap — alligator or vegetable-tanned calf — typically lasts between 18 and 36 months with regular wear, depending on exposure to sweat and humidity. Casati Milano straps carry an 18-month warranty against manufacturing defects. Rotating between two straps significantly extends the life of both.
