Strap for Seamaster Planet Ocean 600M Co-Axial 42 Stainless Steel / Orange Numerals / Bracelet

The Seamaster Planet Ocean 2201.51.00 has a lug width of 20mm. This is the distance between the two holes of the case lugs where the strap is attached. It is important not to confuse the lug width with the total case diameter (42mm). All our 20mm straps are compatible with this reference and fit correctly without modifications.

The best strap depends on the intended use and aesthetic preferences. For elegance and longevity we recommend alligator or shell cordovan; for everyday robustness, vegetable-tanned calf leather. The 42mm steel case demands a leather solution that honors its visual weight and instrumental vocation. Avoid straps that are too thin or have light textures: the Seamaster deserves constructive and visually proportionate proposals.

The change is simple and does not require specialized tools. Locate the pins that attach the strap to the case lugs (one on each side). Use a spring bar tool to compress the pin and slide it out of the lug. Remove the old strap, insert the new one by aligning the holes with the lugs, and reinsert the pins. Make sure they click correctly into their seats. If you prefer professional assistance, the Casati Milano atelier offers personalized service.

Yes, all straps with 20mm lug width are compatible with the Seamaster Planet Ocean 2201.51.00. On milanostraps.it you will find a selection of 20mm straps handcrafted in quality leather (alligator, calf, shell cordovan) and technical materials, all ready to ship with the option of customization in sizes, initials, and thread color.

Durability depends on the tanning method and use. Vegetable tanning on calf leather offers superior robustness and quick recovery after exposure to moisture, with an estimated 3-5 years of intensive use. Alligator, more sensitive to humidity, is best used in formal settings and requires greater maintenance. Shell cordovan is the longest-lasting solution, resisting time well. All our straps include an 18-month warranty and specific care instructions.
