FAQ

What is the lug width of the Omega Constellation 121.57.35.50.02.001?

The Omega Constellation 121.57.35.50.02.001 has a lug width of 18mm. This is the distance between the case lugs where the strap or bracelet attaches. To verify it, measure the space between the lug pins (lug-to-lug).

What strap do you recommend for the Constellation 121.57.35.50.02.001 in white gold?

For this white gold reference, we recommend black or dark brown alligator to maintain formal sophistication, or calf leather in contrasting tones (burgundy, blue) for a more dynamic character. Vegetable tanning is ideal if you desire leather that patinas and transforms over the years, developing a unique tactile history.

How do I change the strap on the Omega Constellation 121.57.35.50.02.001?

You will need a springbar tool or should consult a watchmaker. Locate the small pins that pass through the case lugs, gently extract them and remove the old strap. Insert the new strap by aligning the holes with the pins, then reinsert the pins. Verify that they are fully engaged on both sides.

Are there aftermarket straps compatible with the Omega Constellation 121.57.35.50.02.001?

Yes, all straps with 18mm lug width are compatible with this model. Milano Straps offers a wide selection of 18mm straps in leather, fabric and rubber, customizable to your specifications with options for length and material suited to your aesthetic preferences.

How long does a leather strap last on a watch like the Constellation?

A quality leather strap, such as alligator or vegetable-tanned leather, has a durability of 3-5 years with regular use, depending on the type of tanning and frequency of use. The leather develops a natural patina that enriches the aesthetics over time. Periodic maintenance (gentle cleaning and conditioning treatment) significantly extends its longevity.
