Strap for Seamaster Planet Ocean 600M Co-Axial 37.5 Stainless Steel / Orange Numerals / Bracelet

The lug width (pin-to-pin) is 18 millimetres. This is one of the most distinctive aspects of this compact model: always verify with a digital calliper before purchasing a compatible strap, measuring the distance between the two lower pins of the lug.

There is no universal choice, but rather choices dependent on use. Vegetable-tanned alligator enhances contemporary elegance while maintaining versatility; shell cordovan develops an amber patina parallel to the case steel; NATO or FKM rubber are ideal for those in aquatic environments. The compact proportion of 37.50 mm accommodates high-quality straps well, even slimmer ones that do not overburden the wrist.

The Seamaster uses classic spring bars. You will need: a dedicated tool for extracting spring bars, patience and a stable surface. Position the tool under the lower pin of the lug, push gently inward to release the spring, extract the pin, and repeat from the other side. To avoid damage to the crystal or finishing, use controlled movements. If inexperienced, entrust the operation to a professional.

Absolutely yes. The 18mm lug width is the international standard for this size: any quality strap with the correct 18mm spring bars is compatible. Avoid generic straps from e-commerce platforms; choose specialist brands that guarantee precise tolerances and lug finishing appropriate to the luxury status of the Omega case.

A quality leather (alligator, shell cordovan, vegetable-tanned calf) lasts on average 3-5 years with moderate daily use and correct maintenance: avoid prolonged exposure to direct sunlight, dry quickly after contact with water, and store in a cool, dry environment. Durability increases significantly if the watch is alternated with other models. Rubber or NATO straps last longer, potentially beyond 7-10 years.
