Frequently asked questions

What is the lug width of the Omega Constellation 123.55.24.60.55.006?

The lug width is 20mm. You can verify it by measuring the space between the lateral lugs (the holes in the case that secure the strap). This dimension is standardized by Omega for this model and ensures compatibility with certified artisanal straps.

Which strap material pairs best with the rose gold of the Constellation?

Cognac alligator is the classic choice to emphasize the warm tones of rose gold. Burgundy or black shell cordovan offers elegant contrast and develops a natural patina over time. For everyday wear, vegetable-tanned calf combines durability and neutral tones that enhance the case without competing visually.

How do I change the strap on my Omega Constellation?

The Omega Constellation features an integrated strap with Griffes, which means strap changes occur through the lateral lugs. This requires care: use a dedicated tool (strap removal tool) or consult a professional to avoid damage to the rose gold case.

Are all straps compatible with the Omega Constellation the same width?

Yes, all straps compatible with this model must have a width of 20mm at the case attachment. However, total length varies depending on wrist circumference. Milano Straps offers length-customizable straps with fitting options through Casati Milano atelier for a perfect fit.

How long does a leather strap last on the Omega Constellation?

Durability depends on usage, humidity exposure, and material. An artisanal alligator or shell cordovan strap lasts an average of 3-5 years with regular maintenance. Vegetable-tanned calf tends to age more quickly (2-4 years) but develops an appreciated natural patina. Milano Straps offers an 18-month warranty on all bespoke straps.
