Breguet
Héritage 5410BB/12/9VV— lug 18mm

The Breguet Héritage 5410BB/12/9VV is fitted with an 18mm lug width at the root, which is the attachment point between the case and the strap. This measurement is essential for compatibility with any aftermarket or custom strap.

For a 35mm white gold case with a guilloché dial, a polished smooth alligator strap in deep blue, burgundy, or black tones is the most coherent choice with the model's neoclassical DNA. Box calf is an excellent alternative for daily wear, thanks to the patina it develops over time and its fine grain that does not compete visually with the guilloché.

The strap is replaced using a dedicated springbar tool, a fine-pointed instrument that compresses the spring bars housed in the lugs. It is recommended to have this operation performed by a watchmaker or specialized retailer to avoid scratching the white gold case, a material particularly sensitive to abrasion.

Yes. Any strap with an 18mm attachment is compatible with the Breguet Héritage 5410BB/12/9VV, provided the thickness of the attachment end is suited to the model's lugs. Milano Straps offers a selection of 18mm artisanal straps made from leather and other materials, designed with proportions consistent with the slenderness of the Breguet case.

The lifespan of a leather strap depends on the leather quality, frequency of use, and exposure to sweat and humidity. A high-quality alligator or calf strap, with regular but not intensive use, has an average lifespan of 18–36 months. Casati Milano straps are covered by an 18-month warranty against manufacturing defects and are made with leathers selected to maximize longevity.
