Strap for Seamaster Diver 300M Co-Axial 36.25 Stainless Steel / Blue / Bracelet

The lug width of the 2222.80.00 is 20mm. This dimension should be verified with a caliper by measuring it between the two case lugs. It is essential to choose a strap compatible with this width to ensure proper attachment and accessory stability.

The ideal strap depends on its use: for diving purposes, a technical rubber or NATO fabric strap maintains diver authenticity. For elegant everyday wear, a strap in alligator, vegetable-tanned calf leather, or shell cordovan imparts sophistication without betraying the model's sporty character. Neutral tones (black, brown, grey) enhance the wave dial and blue bezel.

The strap is replaced by removing the lug pins using a spring bar tool. Insert the tool into the pin access hole, release the spring and extract the pin from the case. Repeat on the other side, then position the new strap by aligning the holes with the lugs and reinsert the pins until the click closes. If uncertain, trust a certified professional.

Yes, the aftermarket offers excellent options. On milanostraps.it you will find a selection of 20mm straps made with highest quality leather (alligator, Italian calf, shell cordovan), customizable and ready for shipment. The Casati Milano atelier also creates custom straps with tailored finishing and 18-month warranty.

The durability of a leather strap depends on tanning quality, use and maintenance. A strap in vegetable-tanned calf leather or shell cordovan typically lasts 3-5 years with daily use and regular care (occasional cleaning, drying after fresh water contact). Technical rubber straps have an average lifespan of 4-7 years before replacement is needed. The warranty offered by specialized artisans typically covers 18 months against manufacturing defects.
