Frequently asked questions

What is the lug width of the Omega Constellation 111.20.36.10.52.002?

The lug width of the Constellation 111.20.36.10.52.002 measures 20 millimetres. This measurement, taken between the two integrated lugs on the case, is specific to this model and represents a rare proportion in the contemporary watchmaking landscape, reserved for watches with a compact case diameter (22.50mm).

What is the best strap for the Constellation 111.20.36.10.52.002?

The choice depends on use and aesthetic statement. For continuity of luxury, black or burgundy alligator leather dialogues perfectly with the two-tone structure in rose gold and steel. Vegetable-tanned calf leather allows patina to develop over time and offers character. A cotton NATO is suited for daily wear. The decisive element is that the strap recognises the chromatic hierarchy of the case: rose gold must tonally prevail.

How do I change the strap on my Constellation 111.20.36.10.52.002?

The lug of the Constellation is integrated into the case, so it is not removable. The new strap must be inserted through the lug itself, an operation that requires delicacy. We recommend entrusting this to a professional: the Casati Milano atelier performs this operation with dedicated tools and verifies that the 20mm width is correct to avoid visible friction on the case.

Are aftermarket straps compatible with the Constellation 111.20.36.10.52.002?

Yes, provided that the strap is specifically constructed for the 20mm lug width. Not all 20mm straps are identical in attachment shape. On milanostraps.it you will find 20mm straps already tested for compatibility with this model, with customisation options in leather, size and stitching.

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

An alligator strap with vegetable tanning, worn daily, maintains structural integrity for 3-5 years, developing patina and character. Duration depends on intensity of use, humidity and climatic conditions. Casati Milano straps include an 18-month warranty on manufacturing defects, and can be regenerated or replaced at the end of their useful life at lower costs than the initial purchase.

The next step

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

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
