Strap for De Ville Prestige Co-Axial 36.8 Yellow Gold / MOP Butterfly / Diamond

The lug width of the De Ville 424.57.37.20.55.001 is 19 millimetres. This construction specification is characteristic of this particular reference in 18k yellow gold and requires specific straps. Measuring correctly the internal distance between the case lugs is essential before ordering an aftermarket strap online.

Authentic alligator is the premium choice: fine grain and natural patina create visual continuity with yellow gold, remaining elegantly thin (1.2mm). Medium-grain calf represents the most versatile alternative: thicker (1.5mm), it develops a fascinating patina of wear over time and absorbs warmth from sun rays. For informal occasions, dirty white calf contrasts splendidly with warm gold.

The De Ville 424.57.37.20.55.001 uses straight spring bars (no integrated deployant). With a dedicated tool (spring bar remover), gently push the pin ends inward to release the old strap. Insert the new strap by aligning it to the lugs, verify that the spring bar is perfectly in place. If you are unsure, contact the Casati Milano atelier for professional assistance.

An authentic alligator or calf strap lasts on average 3-4 years with daily use, developing a fascinating patina over time. Durability depends on the environment (humidity, UV, sweat) and care (regular drying, annual conditioning with natural wax). The Casati Milano atelier guarantees 18 months on its own bespoke work and offers regeneration services to extend the strap's life.
