The lug width of this reference is exactly 20 millimeters, measured between the internal points of the pins that emerge from the case lugs. This dimension is fundamental to ensure correct strap interchangeability and maintain the original Omega aesthetic proportions.

Black alligator with écru stitching represents the most versatile and durable solution. However, vegetable-tanned calf leather offers patina evolution over time, while shell cordovan represents a refined alternative. For intensive marine use, FKM rubber strap guarantees superior resistance to chemical agents and chlorine.

The strap is replaced by removing the pins that pass through the case lugs using a dedicated tool (spring bar remover). Insert the pin into the lower hole of the bracket to disengage the spring bar, then extract the old strap. Insert the new strap and reinsert the pin until it locks correctly.

Yes, any strap with a 20mm lug width is compatible. The quality of the aftermarket strap depends on the artisan workshop: premium leather, precise finishing and constructive durability are factors that characterize straps made by specialized ateliers such as Milano Straps.

With regular use, an alligator strap lasts 5-8 years. Vegetable-tanned calf leather has a similar lifespan but develops patina over time. Longevity depends on frequency of use, exposure to moisture, storage and periodic maintenance (conditioning with specific products). A vulcanized rubber strap lasts an average of 4-6 years with intensive use.
