Strap for DS Action Black Rubber

The lug width for the Certina DS Action C013.410.17.057.00 is 20mm. This measurement represents the internal distance between the lugs of the case and is essential for strap compatibility. Universal straps cannot be used; a strap specifically manufactured for this dimension is required.

The choice depends on intended use and personal preferences. For formal-sport contexts, an alligator strap with vegetable tanning is recommended; for humid environments or manual work, vulcanised rubber offers superior durability and grip; for daily versatility, a canvas NATO ensures ease of change. The Certina DS Action accommodates any of these options thanks to its robust 40.50mm steel case.

The strap is secured to the lugs via spring bars, two small metal pins located at the extremities of the lugs. Using a dedicated tool (spring bar tool), push the pin towards the case centre, remove the old strap, and insert the new one, aligning it with the lug holes. The procedure requires care to avoid scratching the steel case.

Yes, provided the strap is manufactured for 20mm lug width. Aftermarket straps of artisanal quality—made from leather with vegetable tanning, shell cordovan or rubber—are fully compatible. Avoid universal-fit straps, which cause excessive play between strap and lugs, compromising aesthetics and functionality.

A quality leather strap with vegetable tanning and protective treatments has an average lifespan of 3-5 years with daily wear. Longevity depends on humidity, perspiration and frequency of use. An alligator or shell cordovan strap, if properly maintained, can exceed 7 years. Vulcanised rubber maintains its properties for approximately 4-6 years.
