Strap for Museum Collection Beijing Winter Olympics 2022 Sedna Gold / Enamel

The model 522.52.39.21.04.001 features a lug width of exactly 20 millimetres. This is Omega's intermediate standard, characterizing many classic models with a 39mm diameter. To verify strap compatibility, measure the distance between the two metal pins (lugs) inside the case: it must be 20mm. An 18mm strap will not fit, and a 22mm strap will have unacceptable play.

It depends on intended use. For formal dress watch wear, black or anthracite grey alligator creates elegant contrast with the rosy tone of Sedna Gold. For a narrative look that ages beautifully, dark brown calf leather in vegetable tanning is ideal. Those seeking everyday versatility can opt for grey NATO or anthracite FKM rubber. Each choice enhances the baguette dial differently while maintaining instrumental legibility as priority.

The procedure is straightforward: insert a spring bar tool into the small hole on the side of the metal lug, apply pressure until the internal pin retracts, and remove the old strap. Repeat on the opposite lug. To install the new strap, align the holes in the leather or fabric with the pins, insert the strap into the first lug, then snap the second pin into place. The operation takes less than two minutes and requires no technical expertise.

Yes, provided the lug width is exactly 20mm. Artisanal straps of superior quality—crafted from premium leathers such as alligator or shell cordovan—often deliver superior aesthetic and tactile performance compared to originals. What matters is that the pins insert correctly into the Omega lugs without play. Online you'll find a selection of compatible 20mm straps, as well as the option to commission bespoke creations from specialised ateliers.

Durability depends on leather quality and intensity of use. Well-maintained alligator in vegetable tanning can last 5-7 years with regular care (gentle cleaning, drying, occasional conditioning). Standard calf leather lasts 2-3 years. FKM rubber is more durable over time, though less refined aesthetically. Users wearing the watch daily in humid environments (bathroom, gym) accelerate wear. A strap is not a permanent component: replacing it periodically keeps the 39mm fresh and allows exploration of new colour combinations.
