Strap for DS-2 Powermatic 80 Stainless Steel / Red

The Certina Heritage Collection C024.407.17.421.00 features lug width of 20mm. This measurement represents the distance between the internal attachment holes of the case lugs and determines the compatible width of all aftermarket straps. To verify it precisely, remove the existing strap and measure the internal space between the lugs.

The Certina Heritage Collection accepts multiple materials with aesthetic coherence. An alligator strap with vegetable tanning emphasises formal vocations; full-grain leather offers versatility between office and casual wear; a cotton NATO conveys sporty pragmatism; vulcanised rubber provides technical functionality. Selection depends on primary usage and wearing context.

Changing the strap on a timepiece with 20mm lugs requires a specific tool—a spring bar tool or thin flathead screwdriver. Place the watch on a soft surface, locate the pins traversing the lugs, extract one by gently pressing laterally, remove the old strap, and insert the new one after reinstalling the pin in the opposite lug. Simple operation, but care must be taken to avoid scratching the case.

All straps featuring 20mm lug width are compatible. milanostraps.it offers a dedicated selection: natural leather (alligator, calf, shell cordovan), NATO straps in cotton and synthetics, vulcanised rubber. Each option is verified to guarantee perfect fit on the case lugs.

The lifespan of a full-grain calf or alligator strap depends on usage and maintenance. With daily, moderate wear, an artisanal-quality strap maintains functionality and aesthetics for 3-5 years. Continuous exposure to humidity, perspiration, and UV rays accelerates ageing. Periodic maintenance (gentle cleaning, conditioning with specialist creams) significantly extends strap longevity.
