FAQ

What is the lug width of the Certina DS Action C032.251.21.031.00?

The lug width of the Certina DS Action C032.251.21.031.00 is 17 mm. This dimension requires bespoke, artisanal straps: standard catalogue straps do not fit correctly. To verify, measure the distance between the base of both lugs using a digital calliper, positioned perpendicularly.

Which strap is most suitable for the Certina DS Action C032.251.21.031.00?

We recommend vegetable-tanned alligator leather for those seeking elegance and natural patina development over time, or structured matt black calf leather to emphasise the sports character of the case. For intensive use in aquatic environments, NATO straps or vulcanised rubber guarantee resistance and minimal maintenance.

How do I change the strap on the Certina DS Action C032.251.21.031.00?

Remove the original strap using a spring bar tool to compress the internal elastic pins. Position the new strap by inserting the elastic pins into the case attachments. Ensure the pins are parallel to the lugs during the operation. If you lack experience, contact our atelier for professional strap replacement.

Will an aftermarket strap compatible with 17 mm work with the Certina DS Action C032.251.21.031.00?

Yes, provided it has been specifically designed for the 17 mm lug width. Not all straps declared "17 mm" guarantee the same fit: leather thickness, base rigidity and lug geometry all affect the final result. Our straps are verified and tested on this specific model.

How long does a leather strap last on the Certina DS Action C032.251.21.031.00?

A high-quality artisanal strap with vegetable tanning typically lasts 4–6 years in moderate daily use. Longevity depends on exposure to moisture, perspiration, UV rays and frequency of use. Regular maintenance—gentle cleaning and occasional conditioning—extends the strap's lifespan.
