Strap for Seamaster Planet Ocean 600M Co-Axial 45.5 Chronograph Stainless Steel / Orange Numerals / Bracelet

The lug width of the Seamaster Planet Ocean reference 232.30.46.51.01.003 is 22mm. This specific width ensures proper compatibility between the strap lugs and the steel case lugs. To measure accurately, use a digital caliper and verify the distance from center to center of the two attachment holes.

For this oversized chronograph we recommend alligator leather straps for uncompromising elegance, vegetable-tanned Tuscan leather for natural aging and patina development, or fluorosilicone rubber for frequent use in marine environments. A deployant clasp is the ideal closure for a case of this size (45.50mm).

Remove the watch from your wrist. Using a spring bar tool (a specialized tool for spring bars), insert the tip into the lateral hole of the lug, gently lift the pin and slide the strap out. Align the new strap with the lugs, reinsert the pin with the spring bar tool and verify that it clicks into place.

Any strap with a 22mm lug width is compatible with this reference. Online you will find a wide range of customizable artisanal straps in leather, color, stitching and length options, with warranty and the possibility of custom adjustment at specialized ateliers.

The durability of a leather strap depends on the tanning method, usage and UV exposure. A well-maintained vegetable-tanned leather strap lasts 3-5 years under normal conditions, developing patina over time. Fluorosilicone rubber is more durable (5-7 years), while high-quality alligator can reach 7-10 years while maintaining elasticity. Periodically washing the strap with fresh water and drying it thoroughly extends its lifespan.
