Frequently asked questions
What is the lug width of the Omega Trésor 428.57.36.60.04.001?
The lug width of the Omega Trésor 428.57.36.60.04.001 is 18 millimetres. This dimensional standard is specific to the 36mm model and allows the use of any artisanal strap compatible with this width, measured between the internal attachment pins.
What is the best strap material for the Trésor 428.57.36.60.04.001?
For the Trésor we recommend alligator for its natural grain that enhances the elegance of Moonshine Gold, or shell cordovan if you desire a patina that evolves over time. Vegetable-tanned calf leather is ideal for those who prioritise initial softness and structural durability.
How do I change the strap on my Omega Trésor 428.57.36.60.04.001?
Remove the original strap by locating the attachment pins at the lugs. Using a spring bar tool, press the small lateral button of the pin towards the centre to release the end, then extract the pin. Repeat the operation on the other side. Insert the new strap by aligning the holes to the upper lug, compress the pin until the locking click, and verify stability.
Can I use an aftermarket 18mm custom strap?
Absolutely yes. Any artisanal strap with 18mm lug width is compatible with the Trésor 428.57.36.60.04.001. Explore our 18mm strap collection to discover options in alligator, shell cordovan and calf leather with customisable deployant.
How long does a leather strap last on the 428.57.36.60.04.001 reference?
A quality leather strap, with vegetable tanning, maintains structural integrity between 4 and 7 years with daily use and proper maintenance.
