Strap for Seamaster Planet Ocean 600M Co-Axial 45.5 Mécanique 24 Sapphires

The lug width of the 2902.50.38 is 22mm. This measurement corresponds to the distance between the case lugs. To verify it, position a millimeter ruler between the two horizontal pins of the attachments (not on the case): you will read exactly 22mm. It is important to measure it with precision to ensure strap compatibility.

A black alligator or cognac brown strap represents the most elegant choice for this model. Alligator amplifies the perception of luxury thanks to its fine and regular texture, creating a sophisticated contrast with white gold and mother-of-pearl. Alternatively, superior quality calf in warm tones (bourbon, mahogany) establishes a chromatic dialogue with the mother-of-pearl itself.

Changing the strap requires minimal tools: a spring bar tool (a specific tool for the lug pins) and a stable work surface. Remove the old strap by pushing the elastic pin inward with the spring bar tool on one side, repeat on the other. Insert the new strap by aligning its attachments with the case pins, then push the pin into its housing until it clicks. Check that the strap is securely fastened on both sides before wearing the watch.

Yes, any aftermarket strap with 22mm lug width is compatible with your Planet Ocean. Milano Straps offers a wide selection of 22mm straps in various materials (alligator, calf, rubber, fabric), both standard and customizable models. Compatibility is guaranteed by the lug width: simply verify that it is exactly 22mm.

A quality leather strap (alligator or calf) lasts an average of 3-5 years with intensive daily use. Longevity depends on climate (humidity accelerates aging), frequency of use, and care. Vegetable-tanned straps develop a natural patina over time, becoming softer and more distinctive. Rubber and fabric last longer (5-8 years). Milano Straps provides an 18-month warranty on straps from the Casati Milano atelier.
