Strap for Seamaster Planet Ocean 600M Co-Axial 43.5 GMT Stainless Steel / Orange Numerals / Bracelet

The lug width of the Seamaster Planet Ocean 232.30.44.22.01.002 is 21mm, measured from the inner edge of one lug to the other. This dimension is specific to the 43.5mm case and is determined by the proportional relationship between the case diameter and crown depth. It cannot be modified without structural intervention on the case.

For this model we recommend Nile crocodile leather in vegetable tanning for sophistication, box-calf for formal versatility, or Formula 1 rubber if you frequently use the watch in aquatic environments. The stainless steel deployant buckle is the ideal solution to protect the leather and ensure controlled opening.

The replacement requires two specific tools: a spring bar tool and a stable surface. Position the watch with the case face down, locate the small groove on the inner end of the lug, gently insert the tool to compress the spring, remove the pin. Repeat the operation on the other lug. We recommend performing this operation on a soft surface (microfiber cloth) to avoid scratches.

Yes, any strap with a 21mm lug width is compatible with the 232.30.44.22.01.002. Always verify that the strap has been made with this exact specification. On milanostraps.it you can choose from various artisanal solutions, all tested for geometric and functional compatibility with this case.

A high-quality artisanal crocodile or calf leather strap, if subjected to ordinary maintenance (quick drying after water contact and annual treatment with odorless balm), lasts 4-6 years. Prolonged exposure to chlorine or salt water reduces longevity to 2-3 years. A rubber strap has similar durability but degrades differently: it gradually loses elasticity after 3-4 years of intensive use.
