Strap for Seamaster Diver 300M Quartz 28 Stainless Steel / Electric Blue / Bracelet

The lug width of the Seamaster Diver 300M 2285.80.00 is precisely 20mm. This measurement is specific to the 28mm model and should be verified before purchasing a replacement strap. Measure the lug width by placing a digital caliper between the case lugs or consult the original Omega documentation.

Vegetable-tanned alligator represents the ideal compromise between elegance and functionality for the Seamaster Diver 300M. Alligator offers characteristic grain, evolving patina over time, and aesthetic compatibility with the model's sport-elegant style. Valid alternatives are shell cordovan (for those who appreciate density and chromatic evolution) and natural rubber (for a pure, waterproof approach).

To change the strap, you must remove the spring bars that connect the original bracelet to the case. Use a spring bar tool (a specific tool for spring bars) to compress the spring and extract the pin. Perform the operation gently to avoid damage. Insert the new strap into the spring bars and ensure the pin is completely locked on both sides. If uncertain, entrust the operation to a specialized atelier such as Casati Milano.

Yes, a strap with a 20mm lug width is compatible with the Seamaster Diver 300M 2285.80.00. It is essential to verify the exact measurement before purchase. Quality artisanal straps made from premium leather (alligator, calf, shell cordovan) or natural rubber adapt perfectly while maintaining correct proportions and wrist comfort.

A premium leather strap, crafted with artisanal techniques and vegetable tanning, has a lifespan of 5-7 years of daily use. Longevity depends on: frequency of use, water exposure, periodic care (gentle cleaning with a soft cloth), and type of leather. Alligator and shell cordovan, due to natural density, require less maintenance. A natural rubber strap can last 3-5 years before showing visible signs of wear. Casati Milano offers an 18-month warranty on all custom straps.
