DS Caimano C0174071603701— lug 20mm

The Certina DS Caimano C0174071603701 has a lug width of precisely 20 millimetres. This dimension corresponds to the width of the spring bars connecting the case to the original bracelet. To verify compatibility with an aftermarket strap, measure with a digital calliper the internal distance between the bar shoulders: it must be exactly 20mm.

We recommend an authentic alligator strap with vegetable tanning as the primary choice, as it replicates the case's stylistic elegance. Alternatively, vegetable-tanned calf with aged patina creates an accessible yet refined character. For a sportive functional profile, select a NATO strap in Ballistic-grade nylon or FKM rubber if you intend to use the watch for diving.

Obtain a dedicated spring bar remover tool. Place the watch face-down on a soft cloth. Insert the flat tip of the tool beneath the spring bar and press gently: the spring will retract partially. Extract the bar, remove the old strap. Insert the new strap's bars first into one case lug, then arc the strap around your wrist and secure the opposite lug. Verify that both bars are firmly seated.

Yes, provided it meets certified artisanal manufacturing standards. In our workshops, 20mm straps for the DS Caimano are measured with tolerance of ±0.1mm and tensile-tested to guarantee durability identical to OEM components. Materials source from established European tanneries with UTIC certification.

An authentic alligator or superior-grade calf strap will last 4–6 years with daily use and periodic maintenance (damp cloth cleaning, conditioner application every 12 months). Longevity depends on exposure to sweat, humidity, and direct sunlight. In protected environments, leather can remain intact for 8–10 years. FKM rubber has slightly greater longevity (6–8 years) due to resistance to chemical degradation.
