Strap for De Ville Trésor 36 Stainless Steel / Brown - Roman / Alligator

The lug width of the Omega Trésor 428.18.36.60.13.001 is 18 millimetres. This dimension is a classic standard that characterises many timepieces of medium proportions. To verify compatibility with a strap, measure the distance between the two lugs with a digital calliper: the value must be 18.00 ± 0.1 mm. Precise measurement prevents ordering errors.

For this timepiece characterised by understated elegance and minimalist design, deep black or slate grey alligator represents the ideal choice, creating an aesthetic continuum with the brushed steel case. Alternatively, a vegetable-tanned calf in cognac brown or hazelnut tones introduces warmth while maintaining the formal character. For everyday versatility, consider NATO straps in high-density fabric or FKM rubber, although these require a more sporty aesthetic setting.

Changing the strap requires the use of a specific tool called a spring bar tool, available in precision kits. Position the watch on a soft cloth with the lugs facing upward. Insert the tool into the small slot at the base of each lug, exerting gentle downward pressure to release the internal spring. Completely remove the old strap and proceed to insert the new one, ensuring the spring is firmly positioned. For those unfamiliar with the procedure, a professional watchmaker can complete the operation in a few minutes.

Yes, any strap with an 18 millimetre lug width is compatible with the Trésor 428.18.36.60.13.001. The important thing is that the width is accurate and that the overall length adapts to your personal wrist measurements. Artisanal straps offer superior construction quality and choice of materials (alligator, calf, cordovan, cotton) compared to OEM offerings, allowing you to personalise the timepiece according to your style.

The lifespan of a leather strap depends on the material, construction quality and frequency of use. A high-quality artisanal alligator or shell cordovan strap, with proper maintenance, offers 3–5 years of daily wear before requiring replacement. A vegetable-tanned calf, being softer, tends to last 2–3 years. The patina that develops over time testifies to usage and personal connection with the watch. Protecting the strap from excessive moisture and prolonged water exposure significantly extends its life.
