The Heritage

The Omega De Ville Trésor 428.55.36.60.99.002 is a contemporary reinterpretation of the 1960s Ladymatic, featuring a 36mm Moonshine Gold case with a champagne dial. Powered by the METAS-certified Omega caliber 4061 movement, it offers excellent chronometry and magnetic resistance. The 18mm lug width is proportioned for optimal balance on the wrist, with 30m water resistance suitable for daily wear.

FAQ

What is the lug width of the Omega Trésor 428.55.36.60.99.002?

The lug width of the Omega Trésor 428.55.36.60.99.002 is 18mm, standard for cases of 36mm diameter. This dimension is crucial to ensure balanced proportions and a perfect fit to the wrist without unsightly overhangs.

Which strap pairs best with the Omega Trésor Moonshine Gold?

Alligator with vegetable tanning remains the primary choice: the deep grain naturally dialogues with the silvery reflections of Moonshine Gold. Bordeaux shell cordovan and gray-tortoiseshell calf are also harmonious pairings that enhance the champagne dial.

How do you change the strap on an Omega Trésor 36mm?

Use a spring bar tool to compress the suspension pins that secure the strap to the case lugs. Insert the tool into the small hole below the bracket, gently release the pressure and slide the strap. Reverse the procedure with the new strap, verifying that the pins engage completely.

Which aftermarket straps are compatible with the 428.55.36.60.99.002?

All straps with 18mm lug width are compatible. We recommend Italian alligator, full-grain calf, shell cordovan and premium NATO straps. Casati Milano straps are customizable in length and feature Omega-compatible finishes.

How long does a natural leather strap last on a daily-wear watch?

With daily use, a high-quality leather strap lasts on average 3-4 years. Durability depends on climate, humidity and frequency of wear. Vegetable tanning develops natural patina and ages elegantly; chrome tanning requires more frequent maintenance. Casati Milano offers an 18-month warranty on all artisanal straps.
