Frequently asked questions

What is the lug width of the Omega Constellation 123.20.27.60.02.001?

The lug width of this model is exactly 16 millimetres. The lug width is the distance between the two metal lugs of the case where the strap is attached. Always verify this measurement by placing a ruler parallel to the two lugs and measuring at the center.

Which strap material pairs best with the Constellation 123.20.27.60.02.001?

Alligator represents the ultimate choice for elegance, especially in cognac or dark brown shades, which enhance the warmth of rose gold. Vegetable-tanned calf offers versatility and develops a natural patina over time. For a contemporary sporty approach, a neutral canvas NATO strap creates striking contrast with the steel and rose gold case.

How do you change the strap on this watch?

The strap is changed by removing the spring bars (the metal pins that secure the strap to the case lugs). Use a dedicated tool or a small flat lever to gently slide the pin laterally. Once removed, the strap detaches easily. Insert the new strap by aligning it with the holes and reinsert the pins until they click into place.

Is a 16mm aftermarket strap compatible with the Constellation 123.20.27.60.02.001?

Yes, any artisanal strap made with a 16 millimetre lug width is compatible with this model. Ensure the strap does not have a different lug width, otherwise you will experience mechanical play or it will not fit into the case lugs.

How long does a leather strap last before it needs to be replaced?

Durability depends on usage and material quality. A high-quality alligator or calf strap, with regular maintenance (drying after moisture exposure), can last 3-5 years of daily wear. Vegetable-tanned leather tends to age better aesthetically, developing a desirable patina. A canvas NATO strap has similar durability, with less maintenance required.
