Strap for DS Action Diver Powermatic 80 Stainless Steel / Blue / Bracelet

The lug width of the Certina DS Action C032.407.11.041.00 is 20 millimetres. This measurement is determined by the distance between the inner pins of the case lugs. We recommend verifying the lug width using a digital calliper, positioning the arms between the inner points of both lugs, to ensure an accurate order with no margin for error.

The choice of strap depends on the intended use. For professional and sports applications, a vulcanised rubber strap offers indefinite durability and minimal maintenance. For formal urban contexts, alligator leather with vegetable tanning ensures an elegant patina developing over time. A Swiss canvas NATO strap represents the most versatile solution, permitting rapid changes without specialist tools. Vegetable-tanned calfskin is the most sustainable choice for daily-wear watches.

Strap replacement is accomplished by removing the lateral pins using a spring bar tool. Position the tool beneath the pin, gently lift upward to release the internal spring, and slide the pin horizontally to extract it completely. Repeat for the second pin. Insert the new pins into the compatible 20mm strap and, using the spring bar tool, compress the springs and insert the pins into the case lugs until they lock audibly. Avoid excessive pressure to prevent damage to the lugs.

All straps with a lug width of 20 millimetres are compatible, regardless of manufacturer. This includes straps in alligator, calfskin, aniline leather, NATO canvas, suede, butyl rubber and vulcanised elastomer, provided the 20mm dimension is confirmed. Milano Straps offers a dedicated collection of Italian leather artisanal straps in this size, customisable according to colour and finish preferences.

Durability depends on tanning method and usage patterns. A vegetable-tanned leather strap, worn daily in an urban environment, retains functional properties for 3–4 years before replacement becomes necessary for aesthetic reasons. Frequent exposure to salt water, intense perspiration or direct sunlight accelerates ageing to 12–18 months. A rubber or vulcanised elastomer strap has virtually indefinite longevity (10+ years) when subjected to intensive use in marine environments. Regular maintenance with dedicated vegetable leather balms significantly extends lifespan.
