Strap for Seamaster Planet Ocean 600M Co-Axial 37.5 Stainless Steel / White / Alligator

The lug width is 18 mm. This dimension is specific to the 232.33.38.20.04.001 model and has been ergonomically calculated to maintain balanced proportions on the wrist. You can verify it by measuring with a calibrated ruler the space between the two lateral lugs of the case.

Alligator is the most sophisticated choice for formal occasions, while vegetable-tanned calf leather offers superior resistance and ages elegantly. Shell cordovan combines elegance with water resistance. For sports use, rubber with steel deployant is practical and lightweight. We do not recommend NATO straps, which tend to disproportionately enlarge the compact diameter of this model.

The strap is inserted into the two lateral lugs of the case (18 mm lug width). Using a specialized tool or spring bar tool, gently remove the current strap from the lugs, then insert the new one by sliding the ends into the same holes. Ensure the strap is firmly seated before wearing the watch.

Any strap with an 18 mm lug width is compatible. On milanostraps.it you will find a selection of artisanal straps in alligator, calf leather, shell cordovan and rubber, all in 18 mm and customizable. The Casati Milano atelier also offers bespoke custom straps with an 18-month warranty.

An artisanal alligator or calf leather strap typically lasts 5-8 years with regular use, depending on frequency of wear and exposure to moisture. Shell cordovan, being more water-resistant, can reach 7-10 years. Casati Milano straps include an 18-month warranty and allow replacement of the lugs to extend the life of the product.
