Strap for DS 1 Lady

The lug width (ansa width) of the Certina DS-1 C0062071105100 is 20mm. This technical specification identifies the distance between the two lateral lugs of the case and determines which strap width is compatible. To verify this measurement, use a digital calliper positioned perpendicularly between the two lugs: the result must be exactly 20mm. This dimension remains constant over time and represents a standard value that allows you to fit any handcrafted strap of the same width.

The ideal strap depends on your personal style and the watch's intended use. For an elegant and formal aesthetic, we recommend a strap in vegetable-tanned leather or alligator, which enhance the understated sophistication of the stainless steel case. If you seek versatility, a NATO strap in reinforced silk or resistant cotton offers practicality without sacrificing elegance. For those who alternate between formal and informal environments, vulcanised rubber ensures grip and durability. Regardless of your choice, all 20mm lug-width straps are compatible with this model.

Changing the strap takes just a few minutes and requires no professional tools. Obtain a springbar tool or a small flat-head screwdriver. Position the watch with the case facing downwards and locate the small holes on the lateral lugs. Insert the blade of the springbar tool gently into the hole, pushing towards the case centre: this will lift the small internal spring of the lug. Simultaneously, remove the old strap. Repeat the operation on the other lug. To fit the new 20mm strap, insert both ends into the housings and ensure the lugs are fully seated until the final click.

Yes, all handcrafted straps with a 20mm lug width are fully compatible with the Certina DS-1 C0062071105100. Aftermarket straps of sartorial quality do not alter the watch's value; rather, they allow further personalisation of the timepiece according to your colour and material preferences. Straps crafted in vegetable-tanned leather, alligator, high-quality calf or technical materials such as NATO and vulcanised rubber mount via the same lugs without any case modification. This compatibility is one of the principal advantages of Certina models with 20mm lugs: you have an almost unlimited range of artisanal options.

The durability of a natural leather strap depends on intensity of use, tanning method, leather type and maintenance. A vegetable-tanned leather strap of quality, worn daily, maintains structural integrity for 2–4 years; surface patina and creasing are part of the natural ageing process. Premium alligator or calf can last longer, even 5–7 years, thanks to more resistant fibre. Visible wear (edge scuffing, slight discolouration) is normal and desirable: it bears witness to the watch's memory. To extend service life, apply a conditioner for natural leathers every 6–12 months and dry any moisture quickly. Strap replacement remains economical and swift thanks to the simplicity of the 20mm lug.
