Strap for Seamaster Diver 300M Automatic 41 Yellow Gold / Skeleton / Bracelet / 50th Anniversary

The lug width is 20mm, consistent across both lugs. This dimension is specific to the model and represents the ideal proportion ratio between the 41mm case and the strap, ensuring visual balance and wrist stability.

For an 18K yellow gold Seamaster we recommend alligator in dark shades (aged cognac, cigar brown) or vegetable-tanned calf to enhance the patina of the gold. Alternatively, a premium rubber strap with satin yellow gold lugs offers practicality while maintaining aesthetic consistency with authorized Omega sports versions.

Use a dedicated spring bar tool to gently compress the elastic pins of the lugs and extract them from the case. Insert the new strap by correctly aligning the holes and reset the pins in the case seats. Avoid scratching the case with precise movements and seek specialized assistance for gold models.

Yes, any strap with 20mm lug width is physically compatible with the case. However, for aesthetic reasons we recommend verifying the strap thickness: the Seamaster Diver 300M pairs best with straps between 3.5 and 4.5mm total thickness.

A quality leather strap (alligator or vegetable-tanned calf) lasts 3-5 years in daily use with proper maintenance. Salt exposure and humidity accelerate aging: we recommend periodic treatments with natural wax and drying after contact with seawater. The Casati Milano warranty is 18 months.
