Trésor 428.58.36.60.11.001— lug 18mm

The lug width of the Omega Trésor 36mm reference 428.58.36.60.11.001 is 18mm. This measurement is essential for purchasing compatible straps. To verify it, measure the distance between the inner lugs of the case using a digital caliper or millimeter ruler, positioned perpendicularly. An 18mm strap is the only format that fits correctly onto the case spring bars.

Alligator represents the most elegant and durable choice for the Trésor in Moonshine Gold. The natural grain of crocodile leather creates a sophisticated texture that pairs perfectly with the neutral tone of the case. Alternatively, vegetable-tanned calf leather in tobacco brown, burgundy, or deep black offers softness and develops a beautiful patina over time. Avoid excessively light straps to prevent chromatic imbalance with the lunar gold of the case.

The strap is changed by removing the spring bars that secure it to the lugs. Position the watch with the strap facing upward, use a dedicated tool (spring bar tool) to compress the internal spring, extract it from the lug, and remove the strap. To install the new 18mm strap, align the holes with the spring bars, compress the internal spring, and insert firmly until you hear a click. If you lack experience, entrust the task to a specialized workshop such as Casati Milano.

Any strap with an 18mm lug width is compatible with the Trésor 428.58.36.60.11.001, provided it is of artisanal quality. On milanostraps.it you will find a selection of 18mm straps in alligator, calf, shell cordovan, and rubber, ready for shipment. The Casati Milano atelier also creates custom straps with your choice of leathers and personalizations (initials, thread color) backed by an 18-month warranty.

The lifespan of a leather strap depends on frequency of use and material quality. An alligator or vegetable-tanned calf strap, if worn 4-5 days per week, maintains structural integrity for 3-5 years before requiring replacement. Wear occurs mainly on the keeper (bending area) and at the strap end. With a rotation of at least two straps, the lifespan of each extends significantly. Casati Milano offers an 18-month warranty on custom creations.
