Strap for DS Caimano Powermatic 80 Stainless Steel / Black / Strap

The lug width of the Certina DS Caimano C035.407.16.057.00 is 20mm. This measurement represents the distance between the two horizontal lugs (pins) of the case and determines compatibility with aftermarket straps. Measurement must be taken on the internal width of the space between the lugs, not on the external case diameter.

The ideal strap depends on the context of use and aesthetic preference. For formal and daytime environments, alligator leather in brown or vegetable-tanned calf provides elegance and durability over time. For sports or summer wear, natural rubber or ripstop NATO straps offer moisture resistance and ease of maintenance. The stainless steel case of the Caimano pairs well with all these solutions.

To change the strap, you will need a dedicated tool (spring bar tool) or the assistance of a watchmaker. The horizontal pins on the case, known as spring bars, must be extracted carefully using the small flathead screwdriver of the tool, inserted into the appropriate slot. Once the pin is removed, the old strap slides away. The new 20mm strap is positioned and the pin is reintegrated, ensuring it is correctly locked on both sides.

Yes, any strap with a 20mm lug width is compatible with the Certina DS Caimano C035.407.16.057.00. Artisanal straps in leather, rubber, canvas, or synthetic material available from specialised suppliers install easily using the original case spring bars, provided they respect the 20mm width specification.

The lifespan of a leather strap depends on the material, tanning method, and intensity of use. An alligator strap with vegetable tanning, worn daily, has a useful life of 3–5 years before requiring replacement. Surface-dyed calf typically lasts 2–3 years. Factors such as sun exposure, humidity, perspiration, and mechanical wear significantly affect longevity. Regular maintenance (gentle cleaning and conditioning) extends the strap's lifespan.
