Strap for Seamaster Diver 300M Automatic 41 Stainless Steel / Black / Bracelet / Maccabiah

The lug width of the 2255.50.00 is 20 millimetres. However, the integrated lugs of the Omega case feature specific geometries and tolerances: not all generic 20mm straps fit perfectly. It is advisable to verify compatibility with models designed to the authentic Omega lug profile to avoid vibrations and excessive play at the terminals.

It depends on use. For formal everyday wear, a cognac brown alligator or bordeaux shell cordovan with steel deployante offers elegance and durability. For saltwater, a NATO nylon or FKM rubber strap becomes essential. Many owners maintain a dual setup: alligator for the office, rubber or NATO for swimming.

The strap is changed by extracting the pins that connect the strap to the case using a dedicated tool (removable pins). There is no need to disassemble the movement. Simply insert the new strap into the 20mm lug terminals, ensuring the fit is perfect and symmetrical. The operation takes just a few minutes and requires no watchmaking expertise.

Technically yes, but it is not recommended. Standard 20mm straps often present tolerances that cause slight play in the terminals of the 2255.50.00. For a perfect fit and optimal tactile feel, it is preferable to choose straps modelled on the authentic Omega lug profile or commission a custom strap from a specialised atelier.

Durability depends on the material and usage. High-quality alligator resists freshwater well and develops a natural patina; saltwater shortens its lifespan. A NATO or FKM rubber strap is nearly indestructible in water. If the strap is subjected to frequent immersion, we recommend having an alternative rubber setup and quickly drying the leather after each water contact. With proper maintenance, an alligator strap lasts 3 to 7 years.
