Seamaster Diver 300M 2562.20.00— lug 20mm

The lug width is 20mm. This measurement is the standard for professional diving watches and is extremely easy to find. To verify it, measure the distance between the two holes where the spring bars are inserted: it must be exactly 20mm. All our straps for this lug width are compatible with the 2562.20.00 model without any adjustments needed.

It depends on your use and personal taste. For a formal pairing, we recommend black alligator in vegetable tanning, which develops patina over time. Shell cordovan in cognac tone is ideal if you seek a strap that ages beautifully. Soft calf in beige is a contemporary choice that lightens the overall appearance. For daily versatility, brown in mottled calf offers character without excess.

The change is simple: remove the spring bars that connect the strap to the case using a small specialized tool (spring bar remover). Be careful not to lose the bars, especially if removing for the first time. Insert the new bars into the aftermarket strap, verify that they are firmly seated in their slots, and you're done. Most quality artisanal straps already include the bars or provide them free of charge.

Yes, absolutely. The important thing is that the lug width is 20mm. Artisanal quality straps such as those made by Milano Straps are crafted with robust stainless steel bars and offer regular stitching that does not damage the steel case. Always verify that the seller specifies the lug width: for your Seamaster exactly 20mm is required.

Durability depends on use, leather type, and stitching. A quality alligator or shell cordovan with vegetable tanning easily lasts 3-5 years of daily use. Calf is slightly less resistant, with a lifespan of 2-4 years. Artisanal stitching with robust thread doubles the life of the strap compared to industrial straps. Casati Milano offers an 18-month warranty on all artisanal straps, a sign of confidence in durability.
