Strap for De Ville Trésor 36 Stainless Steel / Silver - Frangipani / Alligator

The lug width of the Trésor 428.18.36.60.02.002 is exactly 18mm. This measurement is binding for the choice of aftermarket strap or bracelet: even half a millimetre deviation compromises the attachment. Verify by measuring it between the two pins on the case before ordering.

For the Trésor 36mm we recommend vegetable-tanned alligator in brown or black for formal wear: the fine grain respects the sobriety of the instrument. Vegetable-tanned calf for those desiring quick patina and softness on the wrist. Cotton-linen NATO for more sporting contexts. The material must be coherent with the Trésor's understated identity.

The Trésor strap is replaced via spring bars: use a spring bar tool to depress the lateral pins. Insert the tool into the small slot under the lug, compress the pin, extract the bar. Repeat on the other side. When mounting the new strap, verify that the pins are well seated in their slots and that the strap is centered.

Yes, but with rigorous attention to the 18mm lug width specification. Generic straps online often fail to respect this specificity, causing defective attachments. Online you will find collections dedicated to Omega models with compatibility certification. The atelier Casati Milano customizes to measure, guaranteeing perfect fit and artisanal construction quality.

A quality leather strap (vegetable-tanned alligator, calf, shell cordovan) lasts 3-5 years with responsible daily wear. Longevity depends on exposure to moisture, sweat and sunlight. Vegetable-tanned leathers patina and age nobly even as they deteriorate; synthetic leathers last less. Light maintenance (periodic cleaning, summer rest) extends the strap's life.
