Strap for Seamaster Diver 300M Master Co-Axial 42 Moonshine Gold / Green / Rubber

The lug width of reference 210.62.42.20.10.001 is 20mm. This measurement represents the linear distance between the two attachment pins and determines the compatibility of any aftermarket strap. It is essential to verify this measurement before purchase to avoid fitting errors.

For the 210.62.42.20.10.001 model in Moonshine Gold, we recommend dark brown alligator, burgundy shell cordovan, or vegetable-tanned red-leather calf. For pure underwater use, vulcanized FKM rubber offers the best salt water resistance. The choice depends on the desired balance between elegance and technical functionality.

The 210.62.42.20.10.001 model uses standard spring bars. Position the watch on a soft support, use a spring bar tool to release the pins from their housings, remove the old strap and insert the new one by aligning the pins to the lugs. We recommend entrusting the operation to professionals to avoid scratches on the case ceramic.

All straps with a 20mm lug width are compatible with reference 210.62.42.20.10.001. Multiple options are available in leather (alligator, calf, shell cordovan), fabric (NATO) and vulcanized rubber. At milanostraps.it you will find a complete selection of customizable 20mm straps.

Durability depends on the material and usage. A quality alligator or shell cordovan, with vegetable tanning, maintains structural integrity for 4-6 years of daily use, developing natural patina. Vegetable calf is slightly more delicate in aquatic environments. Casati Milano straps include 18 months warranty and ongoing maintenance through WhatsApp support.
