Breguet
Classique 5177BA/12/AV0— lug 18mm

The lug width of the Breguet Classique 5177BA/12/AV0 is 18 mm. This is the measurement to use when selecting any compatible strap, whether purchasing online or for bespoke work at Casati Milano.

For a Classique in yellow gold, the most suitable strap is Mississippi alligator or hornback leather with fine grain, in bordeaux, tobacco, or cognac tones. High-quality crocodile leather complements the guilloché dial and pairs chromically with the 18-karat yellow gold case. Polished box-calf leather is an alternative of absolute formal quality.

The strap is replaced using a fine-tipped springbar tool, leveraging between the lug and strap to compress the spring bars. It is recommended to work on a soft surface to avoid scratches to the yellow gold case and to use replacement spring bars with a diameter compatible with the original Breguet lugs.

Yes. All straps with 18 mm attachment and standard termination are compatible. Milanostraps.it offers a selection of 18 mm straps in leather and premium materials, with bespoke options through Casati Milano for those who want custom work with choice of leather, color, and stitching type.

A high-quality alligator or calf leather strap, with regular but careful use, has an average lifespan of 2-4 years. Longevity depends on exposure to sweat, water, and UV rays. Rotating between two straps, avoiding prolonged water contact, and occasionally applying conditioner to fine leather are practices that maximize durability and preserve the patina.
