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

The Omega Trésor 428.18.36.60.11.001 has a lug width of 18 millimetres. This dimension is fundamental for compatibility with aftermarket straps: all straps featuring 18mm lugs are directly compatible with this model. You can manually verify the measurement with a digital caliper by measuring the distance between the two lateral attachment points of the case.

For the Omega Trésor 428.18.36.60.11.001, alligator leather straps are ideal, as the absence of pronounced grain maintains the minimalist elegance of the watch. Dark blue or cognac alligator pairs perfectly with the Trésor blue dial. Alternatively, structured calf leather and shell cordovan offer a more pronounced tactile sensation, while rubber or NATO fabric straps are perfect for casual contexts without compromising the sobriety of the design.

Strap replacement is a straightforward operation: position the watch on a stable surface, and you will notice two small pins (spring bars) connecting the strap to the lugs. With a specific tool or small lever, press the pin to unlock it and slide the strap out of the lug. Repeat the operation on the other lug. To install the new strap, insert one end into the lug, then position the spring bar pin and press until it clicks into place. The operation takes only a few minutes and requires no special skills.

Yes, all straps with 18 millimetre lugs are compatible with the Omega Trésor 428.18.36.60.11.001. Compatibility is guaranteed by the standardisation of lug width: a handcrafted 18mm strap from any brand will fit perfectly to the case attachment points. However, it is important to consider strap thickness: materials that are too rigid may exert excessive pressure on the spring bars, compromising durability over time. Handcrafted leather straps offer the right flexibility.

A quality leather strap, worn daily, has an average lifespan of 4–7 years depending on use, climate and care. Genuine leather naturally patinas over time, acquiring visual character. Alligator and shell cordovan straps, being denser materials, tend to last beyond 7 years. Maintenance is essential: avoid prolonged exposure to direct moisture and occasionally apply specific conditioning oils. Rubber or NATO fabric straps have comparable lifespans, with the advantage of requiring minimal maintenance.
