Strap for Seamaster Planet Ocean 600M Co-Axial 42 Stainless Steel / Orange / Bracelet

The lug width is 20mm, measured from the inner point of the lug to the opposite side of the case. This measurement is constant across all examples of this reference and allows strap changes without risk of misalignment.

The optimal choice depends on usage: vegetable-tanned alligator offers formal elegance and controlled aging; shell cordovan ensures historical patina and durability exceeding 10 years; vulcanized rubber is ideal for diving and sports activity. All available custom-made in the 20mm version.

The Seamaster Planet Ocean uses standard spring-loaded lugs. Insert a pin removal tool under the first lug, apply gentle pressure to push the retention pin. Repeat on the opposite lug. The strap slides off easily. Installation is the reverse: align the lug holes with the lugs, insert the pin and verify visual engagement.

Yes. Any strap constructed with a 20mm lug is compatible, provided the lug does not exceed 20.3mm external width (to avoid friction on the case). Artisanal straps with certified 20mm brushed steel lugs are the optimal choice for mechanical reliability and aesthetic consistency with the original case.

An alligator or calf strap with vegetable tanning, worn 5-6 days a week, lasts 4-6 years before replacement due to natural wear. Shell cordovan extends to 8-10 years. Durability increases if the strap is rotated (used non-consecutively) and protected from prolonged moisture and direct heat sources.
