Frequently asked questions

What is the lug width of the Omega Trésor 428.18.36.60.10.003?

The lug width of the Trésor 428.18.36.60.10.003 is exactly 18mm. This measurement is critical when purchasing a compatible strap: a 20mm or 16mm strap would not fit correctly between the case lugs. To verify this measurement, position a digital caliper between the two lateral lugs of the case at the innermost point.

Which strap material is best suited for the Trésor 428.18.36.60.10.003?

For a 36mm watch with a Globemaster blue dial, dark brown alligator or vegetable-tanned calf leather offer the best aesthetic and functional balance. Alligator creates visible texture and natural patina over time; calf ensures minimalist simplicity. Rubber is ideal for intense daily use or nautical wear, while reinforced canvas NATO allows quick changes and practicality.

How do you change the strap on the Trésor 428.18.36.60.10.003?

The Trésor 428.18.36.60.10.003 uses standard spring bar attachments. To change the strap: 1) obtain a spring bar tool; 2) insert the tip into the spring bar slot to lift it; 3) remove the spring bar from the lugs; 4) repeat on the other side; 5) align the new strap lugs with the attachment axes and reinsert the spring bars. This procedure requires precision but no specialized tools.

Is there a verified aftermarket strap compatible with the Trésor 428.18.36.60.10.003?

Yes, milanostraps.it offers an extensive collection of artisanal 18mm straps specifically designed for this lug width. All straps are crafted from premium leathers (alligator, shell cordovan, vegetable-tanned calf) and are customizable for length, initials, and stitching type. Consult the 18mm strap section to see available options.

How long does a leather strap last on a daily-worn watch like the Trésor?

A quality leather strap, with vegetable tanning or shell cordovan, lasts an average of 3-5 years with daily use and regular maintenance (periodic cleaning, drying after moisture). Alligator tends to last longer due to its more compact dermic structure. Rubber offers superior durability (5-8 years) but requires less maintenance. Casati Milano offers an 18-month warranty on all straps, with the option of leather regeneration through specific treatments.
