Strap for Seamaster Planet Ocean 600M Co-Axial 45.5 Master Chronometer GMT Deep White Sapphire

The lug width of the Seamaster Planet Ocean 215.98.46.22.05.001 is 22mm. This measurement is the space between the lateral lugs of the case and allows the use of artisanal straps specifically constructed for this dimension. To measure correctly, position a caliper at the case shoulders (lateral zones) with the strap removed.

For a Planet Ocean of this caliber, black or dark blue alligator represents the most coherent choice: the geometric grain amplifies the perception of technical control and develops a natural patina over time. Regenerated calf (box calf) offers greater tactile softness, while structured rubber guarantees total water resistance and aesthetic continuity with the ceramic case. Ballistic nylon NATO straps are the most functional solution for extreme environments.

To change the strap, remove the titanium lugs that connect the strap to the case shoulders. Use a spring bar tool or flat-head spatula to gently disengage the pins. Insert the new 22mm strap into the lugs, ensuring the ansa enters with millimetric precision without play. Check that the lugs are well secured after assembly. If you are not experienced, entrust the task to a certified Omega watchmaker.

The 22mm artisanal straps available online from milanostraps.it are fully compatible with the Seamaster Planet Ocean 215.98.46.22.05.001. We recommend quality materials (alligator with vegetable tanning, box calf leather, structured rubber) with <a href="/pages/termine-glossario/deployante">deployante</a> in titanium or stainless steel. Custom straps by Casati Milano, made to measure, guarantee total personalization and an 18-month warranty.

A premium quality leather strap (alligator with vegetable tanning, regenerated calf) on a watch worn daily lasts an average of 3-5 years, with significant variations based on frequency of use, water exposure, and body perspiration. Structured rubber has greater resistance (5-7 years). Leather aging is not deterioration, but aesthetic evolution: the patina that develops amplifies the historical value of the watch. Regular maintenance (cleaning, hydration with specific creams) significantly extends the life of the strap.
