Strap for Seamaster Planet Ocean 600M Co-Axial 42 Titanium / LiquidMetal / Rubber

The lug width of reference 232.92.42.21.03.001 is 20mm. This dimension is specific to this model and requires straps compatible with 20mm attachments. To verify accuracy, measure the distance between the inner edges of the two lugs machined into the titanium case.

It depends on usage: premium alligator creates visual sophistication with titanium and is ideal for mixed wear; vegetable-tanned calf offers initial softness and natural patina over time; high-density nylon NATO or FKM rubber are technical choices for regular diving and humid environments. We recommend alligator or calf for 90% of owners.

Strap replacement is done by disengaging the lugs from the case: many modern Seamasters feature a deployant clasp with quick-release button, which facilitates the operation. If not present, use a dedicated tool (spring bar tool) to gently push the retention pin. Always verify that the new strap has attachments dimensioned exactly at 20mm.

Yes, provided it is dimensioned at 20mm lug width. Italian artisanal straps in alligator, calf, or rubber with 20mm attachments are fully compatible and guarantee superior quality to many original straps. Always verify that the attachment hole to the pin is precise.

A quality alligator or calf strap, used regularly (not while diving), lasts between 5 and 8 years before requiring replacement. Constant exposure to salt water or fresh water reduces durability to 2-3 years. For frequent diving, we recommend FKM rubber straps, which last 7-10 years regardless of moisture.
