Frequently asked questions

What is the exact lug width of the Omega Constellation 131.20.36.20.08.001?

The lug width of this model is 22mm (inner to inner). You can verify this measurement with a digital calliper positioned between the two strap attachment pins. Always ensure that any aftermarket strap is cut specifically for 22mm to guarantee compatibility.

Which strap material pairs best with the Constellation 131.20.36.20.08.001?

Alligator in black, burgundy or brown tones represents the most elegant choice for the two-tone configuration (gold and steel). Alternatively, vegetable-tanned calf leather offers daily versatility and ages with character. For a more sporty spirit, a woven cotton NATO strap maintains sobriety without compromise.

How do I change the strap on my 36mm Omega Constellation?

The change requires a spring bar tool available online. Position the watch on a soft cloth, insert the tool into the small slot next to the pin until you extract the retention spring, then pull out the pin. Repeat from the opposite side. Align the new strap, reinsert the pins ensuring they click into place. If you are unsure, consult a qualified watchmaker.

Which aftermarket straps are compatible with the Constellation 131.20.36.20.08.001?

Any strap cut for 22mm lug width is compatible. On milanostraps.it you will find a complete collection of 22mm straps in alligator, calf, shell cordovan, NATO and rubber, all verified for compatibility with Omega Constellation and other models in this case category.

How long does a leather strap last on a watch worn daily?

A quality alligator or calf strap, with vegetable tanning, has an average lifespan of 3-5 years with daily wear. Longevity depends on maintenance (periodic cleaning, drying after water contact) and the degree of exposure to sweat and humidity. Casati Milano artisanal straps include 18-month warranty and can be refurbished at the atelier.
