What I'm asked about the Omega Trésor 428.17.39.60.01.001
What strap size does the Omega Trésor 428.17.39.60.01.001 take?
The Omega Trésor 428.17.39.60.01.001 needs 19 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Omega Trésor 428.17.39.60.01.001 be changed?
Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.
Can I put a leather strap on the Omega Trésor 428.17.39.60.01.001?
Yes, in 19 mm leather. On a 39 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Omega Trésor 428.17.39.60.01.001?
A thin 19 mm alligator. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
Which strap is best suited for the Omega Trésor 39 mm 428.17.39.60.01.001?
For the formal restraint and lacquered black dial of the 428.17.39.60.01.001, alligator straps with vegetable tanning or shell cordovan are the most coherent choice. In dark alligator, the strap enhances the case geometry without distraction. Alternatively, chocolate brown vegetable calf with steel deployant offers versatility for daily wear.
Is an aftermarket 19 mm strap truly compatible with the 428.17.39.60.01.001?
Yes, provided the lug width is specifically designed for a 19 mm measurement. Many generic suppliers offer 20 mm straps mislabeled as 19 mm: this creates excessive play that accelerates wear. Casati Milano artisanal straps are custom-made with precision tolerances, guaranteeing perfect compatibility.
How long does a natural leather strap last on a daily-worn watch?
A high-quality artisanal alligator or shell cordovan strap lasts 5–8 years with daily wear, depending on tanning type and maintenance. Natural leather patinas and changes appearance over time, but this is intentional. A vegetable calf strap tends to give way sooner (3–5 years), unless regularly conditioned with natural oils. Casati Milano warranty is 18 months against manufacturing defects.
The next step
The right strap isn't chosen. It is built, together.
