FAQ
What is the lug width of the Certina DS Action C013.417.44.087.00?
The lug width (ansa in Italian) of the Certina DS Action C013.417.44.087.00 is precisely 21 mm. This dimension is specific to this model and requires custom-made straps, excluding universal or generic accessories. The spring bars must be positioned with accuracy to ensure the strap adheres correctly to the titanium case without compression at the lugs.
Which strap is most suitable for the Certina DS Action C013.417.44.087.00?
For the DS Action we recommend three primary options: vegetable-tanned alligator for those seeking patina and character over time; vegetable-tanned calf for sober elegance and daily durability; FKM rubber for users operating the chronograph in diving or extreme environments. The choice depends on actual usage: if the DS Action is primarily a dive instrument, rubber is logical; if worn also in formal contexts, alligator adds sophistication.
How do you change the strap on a Certina DS Action C013.417.44.087.00?
The change requires a dedicated tool (spring bar tool) and seconds per lug. Position the tool on the small hole of the spring bar, apply light pressure to slide the bar out, remove the old strap. The new 21mm strap is inserted by threading one end of the spring bar into the lug seat first, then the other. Verify that both sides are perfectly seated. The operation is reversible and requires no specialised knowledge.
Is there a compatible aftermarket strap available for this lug width?
Yes, numerous quality manufacturers offer 21mm straps. Certina itself supplies original variants, but the artisanal market—especially European—offers alternatives superior in raw materials and construction. A 21mm leather aftermarket strap allows you to change the aesthetic character of the DS Action without modifying the case, maintaining full mechanical and structural compatibility.
How long does a leather strap last on a watch like the DS Action?
A quality vegetable-tanned leather strap on a daily-worn instrument like the DS Action has an average lifespan of 3–5 years before showing structural degradation signs (tears, lug-wear). Black leather resists slightly longer than brown due to tintorial stability, but the primary variable is wearing frequency and moisture exposure. A rotated strap with others achieves significantly longer life. Rubber, by comparison, exceeds 10 years without sensible degradation.
