Frequently asked questions
What is the lug width of the Omega Constellation 131.20.39.20.52.001?
The Omega Constellation 131.20.39.20.52.001 has a lug width of 24mm. This measurement is the space between the two case lugs where the strap is inserted. Always verify compatibility before purchasing.
Which strap material is most suitable for the two-tone Sedna Gold and steel Constellation?
Natural alligator represents the most elegant choice thanks to its characteristic grain that pairs perfectly with Sedna Gold. Shell cordovan offers robustness and noble aging. Italian calf leather is the most practical and versatile alternative, especially in dark brown or grey.
How do you change the strap on the Omega Constellation 131.20.39.20.52.001?
The strap is replaced by removing the spring bars (the elements that connect the strap to the lugs). Use a dedicated tool (spring bar tool) to compress the internal spring and extract the pin. Insert the new strap by applying the same pin. If you are not experienced, consult a specialized watchmaker.
Can I use aftermarket straps on an Omega Constellation in this price category?
Absolutely yes. Artisanal straps in alligator, shell cordovan or superior quality calf leather are compatible and often elevate the overall aesthetics of the watch. The important thing is to verify that they have the correct lug width (24mm) and lugs suitable for the case diameter.
How long does a quality leather strap last on a daily wear wristwatch?
A quality alligator or shell cordovan strap, with proper maintenance (drying after rain, protection from impacts), typically lasts 3-5 years of intense daily use. Vegetable tanning ages magnificently and can last even longer, developing an increasingly rich patina.
