Frequently asked questions

What is the lug width of the Omega Constellation 131.55.28.60.55.004?

The lug width for this model is 18mm. This measurement is crucial when selecting a compatible strap. You can verify the measurement by measuring the space between the case lugs on the outer side: it must be exactly 18mm.

What is the best strap for the Omega Constellation 28mm Sedna Gold?

We recommend brown alligator with natural grain for warm contrast with the rose gold, or vegetable-tanned calf leather for those preferring a smooth texture and dignified aging. Black calf is ideal for formal occasions, while a navy NATO offers practicality and casual style.

How do I change the strap on my Omega Constellation 131.55.28.60.55.004?

Strap changing requires two tools: a spring bar tool (pointed extractor) and another point to hold the pin in position. Insert the point into the pin hole from the lower part of the lug, press gently upward until the pin retracts, then extract the strap. Repeat on the other side. Lower the pin into the new strap until it clicks into place.

Can I use an 18mm aftermarket strap on this Omega?

Yes, any strap with an 18mm lug width is compatible. You can choose from alligator, calf leather, shell cordovan, vegetable tanning, NATO, rubber or fabric, as long as the width is exactly 18mm. On milanostraps.it you will find a selection of handcrafted straps ready for shipment and customizable.

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

A quality vegetable-tanned leather strap, worn daily on a lightweight 28mm watch like the Constellation, maintains full functionality for 3-5 years. Wear depends on frequency of use, sun exposure and humidity. Casati Milano straps come with an 18-month warranty and can be repaired or replaced at the atelier.
