Breguet
Héritage 5497PT/12/PB0— lug 20mm

The lug width of the Breguet Héritage 5497PT/12/PB0 is 20mm. This is the standard width at the case lugs for this reference and determines the size needed when purchasing any compatible strap, whether original or aftermarket.

For a platinum Héritage with guilloché dial, the most appropriate strap is alligator belly or hornback with polished finish, in shades of cognac, cordovan, or midnight blue. Smooth black box-calf is the most formal alternative. Both options respect the dress-watch vocation and artisanal character of the Breguet tourbillon.

The strap is replaced by removing the spring bars seated in the case lugs, using a dedicated spring bar tool or lever. The operation is reversible and does not require a watchmaker's intervention, but for a platinum Breguet, care should be taken to avoid scratching the case. The original Breguet spring bars measure 20mm between centers.

Yes. Any strap with a 20mm lug width is technically compatible. Milano Straps produces custom artisanal aftermarket straps in alligator, calf, and other materials sized for this reference, with leather quality and finishing comparable—and in some cases superior—to the original factory strap.

A quality leather strap—alligator or box-calf—typically lasts between 2 to 4 years with daily wear, depending on exposure to sweat, water, and abrasion. With proper care, rotation with other straps, and protection from prolonged moisture, useful life extends significantly. Milano Straps offers an 18-month warranty against manufacturing defects.
