Strap for Seamaster Diver 300M Co-Axial 41 Stainless Steel / Blue / Bracelet

The lug width of the 2220.80.00 is 20mm. This measurement corresponds to the distance between the lateral lugs of the case and is essential for selecting compatible straps. Measuring perpendicularly between the two lugs with a ruler ensures absolute precision.

The choice depends on usage: vegetable-tanned alligator offers elegance and natural patina for formal occasions; shell cordovan resists moisture and salt water exceptionally well for water activities; calfskin provides a versatile compromise. For frequent diving, an FKM rubber or NATO nylon strap is the most technical and durable solution.

Remove the old strap using a springbar tool to push the elastic pins inward. Insert the new strap by aligning it with the holes, then reposition the pins. Ensure that both sides are fully engaged before wearing the watch.

A strap is compatible only if it has an exact lug width of 20mm. Always verify the seller's specifications: even 1mm difference makes the strap unusable. milanostraps.it offers a curated selection of 20mm straps verified for compatibility with this reference.

A quality leather strap (alligator, cordovan, premium calfskin) lasts 3-5 years with regular use and proper maintenance: dry after accidental water contact, avoid prolonged direct sun exposure, occasionally apply conditioning balms. Frequent water use (chlorine, salt) reduces durability to 2-3 years; in this case it is advisable to alternate with technical rubber straps.
