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

The Omega Seamaster Planet Ocean 2900.51.82 uses straps with a lug width of 22mm. This dimension is specific to this generation of professional divers and is essential to ensure a perfect fit to the case lugs without play or misalignment.

For this 45.50mm diver we recommend leather straps with vegetable tanning (cognac, dark brown or black) for everyday wear, or FKM rubber and NATO fabric for diving. Alligator is appropriate for formal contexts. Choose generous thicknesses (1.4-1.6mm) that support the weight of the case without bending.

Unscrew the crown, then use a spring bar tool to compress the parallel attachment rings located at the ends of the strap. Once released, remove the old strap and insert the new one by aligning it with the case lugs. Make sure the lugs are correctly positioned before wearing the watch.

Any strap with a 22mm lug width is compatible with the 2900.51.82. On milanostraps.it you will find a selection of 22mm models in vegetable leather, alligator, rubber and NATO fabric, all made with artisanal quality and customizable according to your preferences.

A vegetable-tanned leather strap typically lasts 3-5 years with moderate daily use, developing a characteristic patina over time. With frequent diving the lifespan is reduced to 2-3 years. FKM rubber lasts 5-7 years. Wear depends on frequency of wetting, sun exposure and leather maintenance (occasional protective treatments).
