Museum Collection 522.53.45.52.04.001— lug 18mm

The lug width of the Omega Museum Collection 522.53.45.52.04.001 is 18 millimetres. This measurement is standard in the aftermarket strap market and allows for a wide selection of materials and finishes. Always verify the measurement by placing a calliper perpendicular to the lugs of the watch.

For Sedna Gold we recommend alligator with vegetable tanning (dark brown or black tones), or shell cordovan from Italian tanneries. These materials develop character over time and create aesthetic harmony with the preciousness of the case. Vegetable-tanned calf remains the versatile option for daily wear. A deployant clasp is essential to protect the lugs.

Position the watch on a padded surface (rubber mouse pad). Locate the small spring bars inside the lugs. Use a dedicated tool or thin screwdriver to apply inward pressure, releasing the pin. Remove the old strap and insert the new one until it clicks into place. Avoid hammering and excessive force on the lugs.

Yes, absolutely. The 18mm lug width is an industry standard. Just ensure the strap is of artisanal quality (alligator, cordovan, vegetable-tanned calf) and features robust stitching. Avoid poor-quality materials: the Sedna Gold deserves aesthetic cohesion. Our Milan Straps are certified for this measurement.

A strap with vegetable tanning lasts 3–5 years with regular use, up to 7–8 years if rotated with other straps. Shell cordovan resists longer (5–7 years of intensive wear). Durability depends on body perspiration, ambient humidity and maintenance. We recommend periodically conditioning the leather and not exposing the strap to direct heat sources. The Milan Straps warranty covers manufacturing defects for 18 months.
