Frequently asked questions

What is the lug width of the Omega Constellation 131.25.29.20.58.002?

The lug width is exactly 18mm. This is the fundamental parameter for strap compatibility. Always verify by directly measuring the distance between the attachment pins with a caliper, as the catalog specification should be confirmed on your specific watch.

What is the best strap for the Omega Constellation 29mm two-tone Moonshine Gold?

Italian alligator leather in vegetable tanning remains the most sophisticated choice: fine grain, regular texture, and patina that evolves over time. French calf in vegetable tanning is an excellent alternative for those who prefer leather with marked color evolution. Pair with a steel deployant clasp to further elevate elegance.

How do I change the strap on my Omega Constellation 131.25.29.20.58.002?

Use a spring bar tool to gently remove the pins from the lugs. Position the tool under the pin, apply light lateral pressure, and pull the pin toward you. Install the new strap using the same reverse method. If you are not experienced, consult a watchmaker: the job takes less than 5 minutes but requires precision to avoid damaging the lugs.

Which aftermarket straps are compatible with the Omega Constellation 18mm?

All straps with 18mm attachment fittings are compatible. On milanostraps.it the collection has been specifically selected for this size. Always verify that the strap has the correct internal spaces (keepers) to slide onto the lugs without friction, especially if you purchase vintage models with thicker lugs.

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

A quality alligator or calf leather strap with vegetable tanning lasts on average 3-5 years with daily wear. Durability depends on personal perspiration, ambient humidity, and care. We recommend letting it air dry after exposure to water or perspiration, and applying a leather conditioner (such as diluted mink oil) every 6-8 months. Shell cordovan, due to its intrinsic density, can last up to 7-10 years.
