Frequently asked questions

What is the best strap for the Omega Constellation 123.20.35.20.02.006?

It depends on usage and aesthetic preferences. For formal occasions, we recommend vegetable-tanned alligator for the patina that develops over time. For daily wear, fine-grained calf offers superior color versatility. Shell cordovan creates deep visual narrative, while vulcanized rubber is ideal for summer and casual contexts.

How do you change the strap on the Omega Constellation 123.20.35.20.02.006?

This requires a spring bar tool (specialized watch tool). Position the watch in a padded vice, gently push the pin from the opposite side until it detaches. Remove the old strap, insert the new one by aligning the holes, and reinsert the pin until the locking click engages. If inexperienced, entrust a certified watchmaker to avoid case damage.

How long does a leather strap last on the 123.20.35.20.02.006?

A quality alligator or calf strap lasts 3-5 years with regular daily wear. Shell cordovan, due to superior material density, reaches 5-7 years. Durability depends on frequency of wear, sun exposure, sweat, and humidity. Patina acceleration does not indicate wear, but rather natural aesthetic evolution of the leather.
