Strap for Seamaster Planet Ocean 600M Co-Axial 45.5 Chronograph Stainless Steel / Diamond / Black / Alligator

The lug width is 22mm. This measurement is specific to the Planet Ocean 45.50mm model and represents Omega's design choice to maintain optimal proportions between the large case diameter and the strap width. To verify compatibility, measure the distance between the two lugs protruding from the case sides: they must be exactly 22mm wide.

Alligator in Havana Brown tone is the most versatile choice: the natural grain creates a unique geometric pattern and the leather has extremely strong structural density. Alternatively, vegetable-tanned calf develops a fascinating patina over time. For those preferring maximum sportiness, the nautical NATO strap in polyamide does not absorb water and allows for quick changes.

Strap replacement is a simple operation: position the watch on a soft support, identify the 22mm lateral lugs that anchor the strap to the case. Using a small tool (spring bar tool), gently press inward to release the lug spring, then extract the strap. Repeat for the opposite side. Finally, insert the new strap by snapping the lugs into the case holes until you hear the locking click.

All straps with 22mm lug width are compatible with the Seamaster Planet Ocean 222.18.46.50.01.001. Milanostraps offers a complete collection of 22mm straps in leather, alligator, shell cordovan, rubber, and technical fabrics. The straps are customizable in length, thread color, and finishes. Compatibility is also guaranteed with Omega OEM straps and other artisanal productions.

A quality leather strap (vegetable-tanned or alligator) lasts on average 3-5 years with daily use, considering frequent exposure to the marine humidity typical of the Planet Ocean. Durability depends on: frequency of water use, sun exposure, cleaning, and periodic maintenance with specific oils. A fluoroelastomeric rubber strap has greater longevity (5-7 years), precisely because it does not absorb moisture. Casati Milano offers an 18-month warranty on all manufactured straps.
