Strap for Seamaster Planet Ocean 600M Co-Axial 45.5 Master Chronometer Chronograph Deep Black ETNZ

The lug width of reference 215.92.46.51.01.003 is exactly 22mm. This width is calibrated for the 45.50mm case and ensures harmonious proportions. You can verify it by measuring the distance between the two lugs of the case (the strap attachment points).

The choice depends on your use: a Tuscan vegetable-tanned leather strap offers elegance and natural patina that improves over time; alligator leather provides a sophisticated texture; an FKM rubber strap is ideal for diving. We always recommend a deployant clasp for optimal pressure distribution.

Strap replacement is done by unscrewing the spring bars from the case lugs. It is recommended to use a specific tool to avoid scratching the ceramic. If you are not experienced, Casati Milano can perform the change by appointment at its bespoke atelier.

Yes, any 22mm strap is compatible with this model. Milano Straps offers a collection dedicated to 22mm straps in various materials: Tuscan leather, alligator, NATO, and rubber, all customizable in sizes and stitching thread.

The lifespan depends on use and environmental conditions. A vegetable-tanned Tuscan leather strap typically lasts 3-5 years with regular use. Prolonged exposure to water, sun, and sweat accelerates wear. Casati Milano guarantees 18 months on its bespoke straps and recommends periodic maintenance.
