Strap for Seamaster Diver 300M Automatic 41 Red Gold / Black / Rubber

The Omega Seamaster Diver 300M reference 2636.50.91 features a 20mm lug width. This measurement is the standard proportion for 41mm cases and is measured perpendicular to the attachment guides between the terminals. A 20mm strap fits onto the case guides without adapters or reducers.

The optimal strap depends on usage: for maximum aesthetic refinement, dark brown or cognac alligator enhances the warmth of the rose gold. For sporting versatility while maintaining elegance, vegetable-tanned calf in tobacco color offers durability and natural patina. For frequent diving, a dark rubber strap with a textured finish combines total water resistance and practicality.

The Omega Seamaster Diver 300M is equipped with straight terminals without proprietary removable bars. Use a dedicated tool to push the lug pins from the inside outward, releasing the strap. Insert the new 20mm strap by sliding the pins through the holes of the internal lugs, ensuring the strap adheres perfectly to the case guides without any play.

Yes, many. Any artisanal or industrial strap with a 20mm lug width is compatible with the 2636.50.91. For superior quality and full customization, high-end artisanal straps in alligator, shell cordovan, and vegetable-tanned calf guarantee longevity and aesthetics equal to or superior to original Omega straps.

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts on average 3-5 years with moderate daily wear. Lifespan depends on frequency of wear, water exposure, type of tanning, and maintenance. Vegetable-tanned straps develop natural patina and can last longer. The standard warranty for artisanal straps is 18 months, including minor repairs.
