Strap for DS Action Diver

The lug width of the Certina DS Action C013.407.17.041.00 is 20mm. This measurement should be taken with the watch positioned face down, measuring the distance between the two horizontal pins that hold the original bracelet. It is essential to ensure the ruler is perfectly perpendicular to the pins for accurate measurement.

The Certina DS Action C013.407.17.041.00, with its sporty 43mm case and black dial, pairs ideally with alligator straps in medium brown or burgundy, NATO straps in dark blue or military green, or anthracite rubber. For formal wear, we recommend vegetable-tanned alligator with stainless steel deployante; for daily sport use, NATO maintains the original tactical character; for water exposure, rubber is the ultimate technical choice.

To change the strap, position the watch on a soft surface with the case face down. Use a dedicated spring bar tool to compress the lateral horizontal pins: insert the small fork of the tool under the pin, apply pressure toward the opposite side, and the pin will retract allowing removal of the old strap. Align the holes of the new strap with the pins and reinsert using the same procedure, ensuring the pin is fully inserted and clicked into position.

Yes, any strap with 20mm lugs and standard pin attachments is compatible with the C013.407.17.041.00. However, it is advisable to prioritise artisanal straps of elevated build quality: vegetable-tanned leather with refined edge painting, robust textile pass-through, and adequately spaced lugs. Low-to-medium quality aftermarket options may compromise the aesthetic balance of a technical movement such as the ETA 2824-2.

The durability of a leather strap depends on usage intensity and exposure to environmental factors. An artisanal vegetable-tanned leather strap of quality construction, subjected to moderate daily use, maintains structural integrity and aesthetic appeal between 18 and 36 months. Exposure to perspiration, fresh water, or salt water accelerates ageing. The natural patina that develops is a feature, not a defect: it represents the visual evolution of the material. To extend durability, periodically rotate the strap and apply protective creams based on natural ingredients.
