Strap for DS Action Diver Chronograph Stainless Steel / Blue

The lug width of the Certina DS Action C013.427.11.041.00 is precisely 20mm. This standard measurement ensures compatibility with the vast majority of aftermarket straps available on the market, providing considerable freedom of choice amongst materials and finishes whilst maintaining construction certainty.

For the C013.427.11.041.00 we recommend alligator leather with vegetable tanning in dark tones for formal wear, vegetable-tanned calf for those desiring natural patina development over time, or NATO and rubber for sporting use and humid environments. Choice depends upon intended use and personal aesthetic preference.

Strap replacement requires extraction of the spring bars positioned between the case and original bracelet. Using a dedicated spring bar tool, apply gentle pressure to one end of the bar until it releases from its housing, then remove completely. Repeat on the opposite side. Next, align the new strap holes with case extremities and reintroduce the spring bars until fully secured.

Yes, absolutely. The 20mm lug width of the C013.427.11.041.00 is standard and permits use of quality aftermarket straps. It is essential to verify that the chosen strap is genuinely dimensioned for 20mm and that the strap lug itself is compatible with the geometric profile of the Certina case.

A quality leather strap (alligator or vegetable-tanned calf), subjected to moderate-to-heavy use, has a serviceable lifespan of between 4 and 7 years. This variability depends upon frequency of wear, moisture exposure, solar radiation and maintenance quality. Leather conditioned periodically with specialist oils and dried immediately after water contact significantly extends practical lifespan.
