Strap for DS Action Blue

The lug width is 20 mm, a widely compatible standard for aftermarket straps. This measurement is obtained by positioning a digital calliper between the inner poles of the lugs, yielding 20.00 mm of usable width. It is essential to verify this dimension before purchasing a strap to avoid instability or mechanical stress on the lugs.

The most suitable strap depends on your intended usage. For formal elegance, an alligator with vegetable tanning or shell cordovan are excellent choices. For a sport-casual approach, we recommend a gummed calf strap, heavyweight cotton NATO, or natural rubber. The latter represents the purest functional solution, particularly if the watch is used for water activities.

The strap is replaced using a dedicated spring bar tool to remove the lug pins. Insert the tool into the spring hole, press gently outward to compress the spring, then slide the pin out of the lug. Repeat on the other lug, maintaining stability and care to avoid scratching the case. Install the new strap by reversing the procedure.

Yes, many high-quality aftermarket straps are compatible with the 20 mm lug width of the Certina DS Action. Always verify that the strap is manufactured for this specific measurement. Artisan suppliers offer options in fine leathers, rubber, or NATO, allowing you to personalise the watch according to your aesthetic and functional requirements.

The lifespan of a leather strap varies based on material composition and usage patterns. If regularly exposed to water (showers, pools), a natural leather strap typically lasts 2–3 years. With more conservative use, it may last 5–7 years. Vegetable-tanned leather is more water-resistant than traditional chrome-tanned leather, but remains an organic material subject to wear. We recommend alternating straps and drying thoroughly after every water contact.
