Strap for DS First Ceramic Chronograph Titanium

The Certina DS First C0144174408100 features a 22mm lug width. This measurement refers to the distance between the two lateral cusps of the lug horns where the strap sits. It is an intermediate standard characteristic of compact chronographs and 41mm sports watches.

A Tuscan leather strap with vegetable tanning in rich tones—midnight blue, dark brown, or black—creates the finest dialogue with the titanium and ceramic case. Alternatively, African alligator offers sober formality, whilst vulcanised rubber amplifies the chronograph's sporty vocation. NATO straps in ballistic canvas represent a versatile choice for frequent changes.

The strap is changed using a specific tool: the spring bar removal tool. Position the small hook inside the current strap's lug, gently lift the spring bar, and the strap slides away. Insert the new strap by sliding both cusps of its lug into the lateral cusps of the case. Release slowly to allow the spring bar to return into position. Never force: the movement must be fluid.

Yes, a 22mm aftermarket strap is completely compatible if of adequate construction quality. Artisanal straps in leather, NATO, rubber, and alligator from 22mm fit precisely onto the case cusps. We recommend verifying that the strap does not exceed laterally the case edges: the fit must be precise with no play.

A high-quality Tuscan vegetable-tanned leather strap lasts between 3 to 7 years, depending on frequency of wear, sun exposure, humidity levels, and maintenance. A sports watch like the C0144174408100, worn daily in active contexts, wears a strap faster than a dress model. Oiling the leather every 12–18 months and drying it after humidity exposure significantly extends durability.
