FAQ
What is the lug width of the Omega Trésor 428.18.39.60.04.001?
The Omega Trésor 428.18.39.60.04.001 has a lug width of 19mm, measured at the inner shoulder of the case terminals. This measurement is critical for selecting compatible straps and ensuring proper fit without lateral play.
What strap do you recommend for the Omega Trésor 428.18.39.60.04.001?
For this model we recommend vegetable-tanned alligator in black or grey, which elegantly complements the silvered dial. Valid alternatives: honey-brown calf for warm tones, or dark grey NATO for everyday versatility. The choice depends on the desired aesthetic register.
How do you change the strap on the 428.18.39.60.04.001?
The strap is removed by inserting a flat tool (spring bar tool) between the case lug and the strap, gently compressing the internal spring until the pin is released. This procedure must be repeated on both sides of the case. The operation requires care to avoid scratches.
Can I use an aftermarket strap on this Omega?
Yes, any strap with a 19mm lug width is compatible with the 428.18.39.60.04.001. Verify that the strap is free from dents and that the spring bar soldering is robust. Reliable brands offer compatibility and construction quality guarantees.
How long does a leather strap last on the Trésor?
A quality alligator or calf strap, with vegetable tanning, lasts an average of 3-5 years in daily use. Lifespan depends on humidity, frequency of changes, and maintenance (periodic cleaning). Avoiding prolonged immersion extends the life of the strap.
