Strap for Planetarium

The CKPT2225 features a 20mm lug width, the ergonomic standard for medium to large European wrists. This measurement ensures uniform pressure distribution on the forearm, essential given the specific weight of the platinum case. Verify compatibility by measuring the distance between the two lugs where the strap attaches to the case.

Selection depends on intended use and personal aesthetics. Alligator leather with vegetable tanning and pronounced grain creates magnificent contrast with platinum. Shell cordovan represents the noblest alternative, with a natural patina that ages coherently with the metal. For casual versatility, a silk NATO with metal deployant is ideal. Rubber remains the solution for maritime environments.

Use a dedicated spring bar tool to gently remove the spring-loaded pins securing the strap to the case. Insert the tool tip into the small hole beneath the lug, pushing laterally to release spring tension. Extract the pin vertically, remove the old strap, and insert the new one, verifying that the pins click correctly into place. Never use sharp objects that could scratch the platinum.

Absolutely. Milano Straps offers a comprehensive selection of straps compatible with 20mm lug width in various materials and finishes. The essential requirement is verifying that the attachment width is precisely 20mm and that the thickness proportion matches the case lugs. Quality aftermarket straps guarantee the same reliability and durability as original equipment, with the added benefit of aesthetic personalisation.

Durability depends on material and usage. Alligator with vegetable tanning can last 5-7 years of daily wear, developing a natural patina over time. Shell cordovan is more resilient and can exceed 10 years. Longevity increases if the strap is protected from excessive humidity and prolonged direct sunlight. Milano Straps recommends applying a protective treatment every 6 months to extend longevity.
