Strap for Seamaster Diver 300M Quartz 36.25 Stainless Steel / Black / Bracelet / Japan

The Seamaster Diver 300M reference 2260.50.00 has a lug width of 20mm. This width is integrated into the case and compatible with all 20mm artisanal straps. To verify the measurement, place a digital caliper between the spring bar terminals and measure the external distance: it must be exactly 20mm.

For the Seamaster Diver 300M we recommend vegetable-tanned alligator for formal wear (natural evolving patina), shell cordovan for uncompromising elegance, brushed calf for everyday versatility, or Tropic rubber if you frequently dive. The choice depends on the dial: dark blue pairs well with medium brown, black requires chestnut or cognac tones, light blue prefers neutrals such as grey or black.

The 2260.50.00 features integrated lugs with spring bar mechanisms. Use a dedicated tool (spring bar tool) to compress the lateral spring and remove the old strap. Align the spring bar terminals of the new strap with the lug seats and push until the attachment clicks into place. Verify the fastening by attempting to lift the strap from the sides: it must be secure and free of play.

All straps with 20mm attachment are compatible with the Seamaster Diver 300M 2260.50.00, provided the lugs are specific to Omega geometry. Artisanal straps from milanostraps.it are crafted with custom-fitted lugs and premium materials, ensuring precise fit and coherent aesthetics. Avoid straps with universal lugs that cause play or incorrect pressure.

A premium leather strap (alligator, cordovan, calf) typically lasts 3-7 years of regular use, depending on frequency of bathing, perspiration, and humidity. Vegetable-tanned alligator develops patina after 18-24 months, improving aesthetically. Milanostraps.it straps include an 18-month warranty and maintenance upon request. To extend longevity, avoid immersions with leather straps: use rubber during intense water activities.
