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

The lug width of the Omega Trésor 428.15.36.60.02.001 is 18 millimetres. This dimension is the historical standard for mid-size watches and requires straps specifically constructed to this specification. Measuring the lug width correctly is essential: position a ruler between the two spring bars that support the strap on the case and read the distance between their outer edges.

The Trésor 428.15.36.60.02.001 pairs beautifully with genuine alligator, vegetable-tanned shell cordovan, or naturally tanned calf leather. Alligator emphasises formal elegance, cordovan guarantees absolute longevity and unique patina over time, while calf offers softness and daily versatility. The choice depends on use: pure elegance for alligator, historical investment for cordovan, elegant practicality for calf.

The two spring bars supporting the Trésor strap are removed using a dedicated tool called a spring bar tool, available from any watch retailer or online. Position the tool under the spring bar, apply gentle pressure inward to compress the internal spring, and the bar will come free. Repeat for both bars. Installation of the new strap is the reverse: insert the spring bars into the case lugs, ensuring the internal spring is fully compressed and locked.

An aftermarket strap is compatible with the Trésor 428.15.36.60.02.001 if explicitly constructed for 18mm lug width. Always verify this specification before purchase. Superior quality straps are made from alligator, shell cordovan, calf, NATO canvas and eco-friendly rubber. MilanoStraps offers a dedicated collection of 18mm straps customisable in length, colour and stitching thread.

A good quality calf strap, with vegetable tanning and correct stitching, typically lasts 3-5 years of daily wear. Shell cordovan resists for 10-15 years or more, developing a fascinating patina. Genuine alligator has a lifespan similar to cordovan if made with traditional methods. Longevity depends on environmental humidity, frequency of wear, leather care and stitching quality. MilanoStraps guarantees 18 months on all artisanal straps made in atelier.
