The Trésor 428.58.39.60.02.001 (aka: 42858396002001), seen from the bench

The Omega De Ville Trésor 428.58.39.60.02.001 is a sophisticated reinterpretation of the Swiss manufacture's watchmaking heritage, featuring a 39mm Moonshine Gold case paired with an Omega 4061 quartz movement displaying hours and minutes only. The case offers 100 meters of water resistance and features a sapphire caseback revealing the movement's construction. The 18mm lug width is proportionally calculated for this model's diameter and ensures balanced visual and functional performance on the wrist.

Frequently asked questions

What is the correct lug width of the Omega Trésor 428.58.39.60.02.001?

The lug width of the Omega Trésor 428.58.39.60.02.001 is exactly 18mm. This measurement is determined by the distance between the two case lugs. Ensure that any strap you purchase strictly adheres to this 18mm tolerance to guarantee compatibility and stable wear.

What is the best strap material for the Trésor in Moonshine Gold?

For Moonshine Gold we recommend straps in natural alligator with fine grain, which reflects light similarly to the case gold. Dark cognac alligator, deep black, or dark blue complement Moonshine Gold excellently. Shell cordovan (for rigidity and natural lustre) and vegetable-tanned calfskin (for evolving patina over time) are also excellent choices.

How do I change the strap on my Omega Trésor 428.58.39.60.02.001?

Strap changes are performed by extracting the spring bars from the case using a dedicated tool (spring bar tool). The spring bars, connected to the old strap via internal springs, are disengaged gently to avoid damaging the metal lugs. The new 18mm strap aligns with the lug holes and the spring bars are reinserted until they click into place. If you are inexperienced, we recommend the strap change service at an authorized watchmaker.

Are aftermarket straps truly compatible with the 428.58.39.60.02.001?

Yes, any strap with an 18mm lug width is mechanically compatible. However, aesthetic compatibility is subjective: the Moonshine Gold case design and the 39mm proportions require straps of elevated construction quality. Generic or poor-quality straps diminish the character of the watch. We recommend fine leathers (alligator, cordovan, vegetable-tanned calfskin) to preserve the watch's narrative coherence.

How long does a leather strap last on my Omega Trésor?

Durability depends on material and use. High-quality alligator, with vegetable tanning and artisanal craftsmanship, lasts 4–6 years in daily wear. Shell cordovan, being more rigid, can last 5–7 years. Vegetable-tanned calfskin evolves gradually and can exceed 8 years. Frequency of sun exposure, humidity, and skin perspiration accelerate aging. Regular maintenance (hydration with specific creams) extends useful life by at least two years.

The next step

The right strap isn't chosen. It is built, together.
