Strap for Seamaster Planet Ocean 600M Co-Axial 43.5 GMT Platinum / Diamond / Abu Dhabi

The lug width of the Seamaster Planet Ocean 232.98.44.22.01.005 is 21 millimetres. This width is specific to this reference and ensures perfect visual integration between the 43.50mm case and the strap. Always verify compatibility by measuring the internal distance between the lug pins before ordering an aftermarket strap.

For a timepiece of this calibre in platinum, natural alligator remains the traditional solution: the regular grain of the leather creates aesthetic balance with the metal's patina. Alternatively, shell cordovan in burgundy or deep brown offers a more substantial texture, ideal for formal occasions. For actual underwater use, a technical NATO or FKM rubber ensures maximum functionality.

The change is performed by removing the lug pins through small lateral holes on the case. Use a precision tool (pin remover) to extract the pin from both sides, taking care not to scratch the platinum case. Once the pin is removed, the strap comes off. Reinsert the pin into the new strap and secure it from both sides. If you prefer to avoid the risk of damage, consult a professional watchmaker.

Durability depends on the material and usage. A quality artisanal alligator strap, with regular maintenance (gentle cleaning, conditioning every 6-12 months), lasts 5-7 years of daily wear. Shell cordovan, being more resistant, can last 8-10 years. Vegetable-tanned leather tends to age more quickly (3-5 years) but develops a unique patina. If you use the Seamaster in frequent underwater contexts, an FKM rubber strap offers unlimited durability with no maintenance.
