Strap for Seamaster Planet Ocean 600M Co-Axial 45.5 Master Chronometer Chronograph Stainless Steel / Grey / Bracelet

The lug width is 22mm. This width is specific to reference 215.30.46.51.99.001 and is not interchangeable with previous Seamaster models. Verify by measuring the distance between the case lugs: it must correspond exactly to 22mm to ensure perfect strap compatibility.

For this 45.5mm case we recommend vegetable-tanned alligator in black, dark brown or midnight blue with thickness 4.5-5mm. Alligator offers pronounced grain and natural elasticity. Shell cordovan is the refined alternative with patina that develops over time. For technical underwater use, FKM rubber remains the unbeatable option.

The Seamaster uses removable pins of 1.5mm diameter. You can request strap changes at authorized Omega service centres, which have specific tools and replacement pins available. Specialized craftsmen can perform the service keeping the watch perfectly intact without risk of case scratches.

Yes, provided the lug width is exactly 22mm and the pins are 1.5mm diameter. Leather or rubber straps handcrafted specifically for this width guarantee total compatibility and often offer superior construction quality compared to standard straps.

On a 45.5mm watch weighing 195 grams, a quality alligator or calf leather strap lasts 3-5 years in daily use, slightly stretching over time. Lifespan depends on sun exposure, humidity and frequency of immersions. Shell cordovan resists longer thanks to superior structural hardness. Regular maintenance and treatment with natural balms extends its life.
