Strap for DS Podium Lap Timer PVD / Black

The lug width (measure ansa) of the Certina DS Podium C034.453.36.057.10 is exactly 21.00 mm. This dimension is specific to this model and is not interchangeable. When searching for an aftermarket strap compatible with this watch, you must verify that it is specifically designed for the 21mm lug width to ensure an optimal fit between the case lugs.

For a sport-elegant chronograph of 42mm such as the DS Podium, we recommend a strap in natural leather with vegetable tanning (dark brown, mahogany) or an alligator strap for those preferring a more refined appearance. If your use is primarily sport or outdoor-oriented, a NATO strap in technical cotton or FKM rubber offers superior practicality and water resistance. The 21mm lug width accommodates all these materials with correct proportions to the case.

Strap replacement is accomplished through the case lugs using a specialised tool: a spring bar tool. Position the tool beneath the strap pass-through (passante), gently press to compress the internal spring (spring bar), and slide the old strap outward. Repeat on the opposite side. To install the new 21mm strap, thread it under one lug, then compress the spring again to insert the pass-through into the opposite eyelet. Verify that the strap is correctly positioned before wearing the watch.

Yes, aftermarket straps are completely compatible with the DS Podium C034.453.36.057.10, provided they are designated for the 21mm lug width. Many artisanal manufacturers offer straps in leather, alligator and technical materials constructed specifically for this lug size. An artisanal strap allows greater personalisation in terms of colour, texture and buckle finish compared to standard Certina options, whilst maintaining identical compatibility specifications.

The lifespan of a leather strap depends on material quality, usage and maintenance. A high-quality vegetable-tanned leather strap has an average longevity of 3-5 years with daily and moderate use, extendable to 7-8 years with rotation among multiple straps and regular maintenance (cleaning with damp cloth, annual conditioning). An alligator or shell cordovan strap resists time significantly better, reaching 10+ years. FKM rubber has a lifespan comparable to leather, whilst technical fabric NATO straps can last indefinitely if rinsed periodically.
