Strap for Classic Date 37 Stainless Steel - Rose Gold / Black / Bracelet

The lug width of this model is precisely 18 millimetres. This dimension was conceived during the design phase as an aesthetic invariant: it ensures correct case curvature of the 37mm diameter against the wrist and must be strictly respected when changing the strap.

For this model we recommend three options: a polished alligator in cognac tones for maximum formality, a vegetable-tanned calf that develops natural patina over time, or a Jacquard canvas NATO for a refined sporty impression. FKM rubber is ideal if you subject the watch to environmental stress.

Position the watch with the dial facing downwards. Using a spring bar tool, gently press inward on the case to release the anchor bar of the left lug width. Remove the bar completely, take off the old strap and insert the new one ensuring that both sides of the bar sit securely in the case cavities.

Yes, any strap with an 18 millimetre lug width is compatible with the lugs of reference 01 733 7578 4334-07 8 18 63. Width is the only relevant technical parameter: verify it before purchase to avoid excessive dilation or constraint between the passants.

A quality artisanal calf strap, if maintained with periodic cleaning and hydration, lasts between 3 and 5 years of daily use. Vegetable-tanned leather develops natural patina that extends its aesthetic life. Deterioration accelerates under conditions of constant humidity or prolonged direct sun exposure.
