Frequently asked questions
What is the correct lug width for the Omega Constellation 111.20.23.60.55.002?
The Omega Constellation 111.20.23.60.55.002 features an 18mm lug width. This sizing is standard for the dress models in the Constellation family in the 22.50mm case diameter version. Always measure from the inner lug shoulder to the opposite shoulder to verify exact strap compatibility.
Which strap is best suited for an Omega Constellation with mother-of-pearl dial and rose gold?
Alligator remains the most harmonious choice: the natural grain creates texture that dialogues with mother-of-pearl without competing visually. Opt for neutral tones (black, dark brown, burgundy) and prefer vegetable tanning that develops patina over time. Smooth calf is a refined alternative if you prefer absolute minimalism.
How do you change the strap on this Constellation without damaging the case?
Use a dedicated spring bar tool, inserting the tip into the thin slot between the lug and the case. Gently press to release the elastic pin, extract the old strap, and insert the new one by aligning the holes. Do not use screwdrivers or sharp objects that could scratch the rose gold and steel.
Which aftermarket strap brands are compatible with the 18mm lug width?
Any strap with 18mm lugs is physically compatible, but for this Constellation we recommend brands specializing in luxury leather: genuine alligator, shell cordovan, or calf with vegetable tanning. Always verify that the spring bars are the correct size and that the buckle/deployant clasp is proportioned to the case diameter.
How long does an alligator or calf leather strap last on a watch worn daily?
A quality alligator strap with vegetable tanning typically lasts 3-5 years of daily wear, developing natural patina and character in the process. Calf tends to wear slightly sooner (2-4 years) but maintains superior elegance if given proper maintenance. Durability depends on wrist conditions, perspiration, and moisture exposure.
