Strap for De Ville Trésor 39 Stainless Steel / Blue - Roman / Alligator

The Omega Trésor 428.18.39.60.03.001 has a lug width of 19mm. This dimension is measured between the two internal lugs of the case and represents the exact width that the strap must have to fit correctly on the watch.

For the Trésor 428.18.39.60.03.001 we recommend alligator or vegetable-tanned calf leather straps, which enhance the dark blue dial of the steel case. Recommended shades: cognac, bordeaux, polished black or taupe. For sports use, the artificial silk NATO strap remains a versatile and reliable choice.

The Trésor features fixed lugs (not spring bars), so strap replacement requires a dedicated tool or the intervention of a watchmaker. We recommend seeking professional assistance to avoid damage to the case, or contacting the Casati Milano atelier for strap installation.

Yes, provided the strap has a certified 19mm lug width. On milanostraps.it you will find a selection of artisanal 19mm straps, customizable and compatible with your Trésor, with a guarantee of quality and precise fit.

The lifespan depends on usage and tanning method. An alligator or vegetable-tanned calf leather strap lasts 4-7 years with daily wear; the patina that develops increases aesthetic character. Casati Milano offers an 18-month warranty on artisanal straps and assists with maintenance and replacement.
