DS Podium C0252172201700— lug 17mm

The lug width of the Certina DS Podium C0252172201700 is 17.00 mm. This measurement refers to the internal distance between the metal lug bars of the case where the strap is attached. It is important not to confuse the lug width with the external width of the strap itself: the Podium's lug bars have a thickness of approximately 2.5 mm, so a 17 mm strap will fit perfectly in the lugs without excessive play.

For the C0252172201700 we recommend three choices in order of elegance and practicality: 1) Polished alligator in black or brown, which reflects the geometric design of the case. 2) Vegetable-tanned calf leather (brown, cognac or grey) for those seeking a natural patina that develops over time. 3) NATO in gabardine for everyday sports use. Shell cordovan is an exceptional but less common choice, ideal for those seeking uniqueness. FKM rubber remains the best solution for water and summer months.

Changing the strap is a straightforward operation. Turn the watch upside down and locate the spring bar pins connecting the strap to the case lugs (one on each side). Use a dedicated tool (spring bar tool) to compress the small internal spring of the pin and slide it out. Once both pins are removed, the old strap comes off. Insert the new strap, aligning it with the lugs, and reinsert the spring bar pins ensuring the spring is positioned correctly. If you are uncertain, contact an authorised Certina service centre.

Yes, any strap with a 17 mm lug width is compatible with the C0252172201700. There are high-quality artisanal straps made by specialised ateliers that often exceed the quality of OEM (Original Equipment Manufacturer) Certina straps. Ensure that the aftermarket strap has metal lug bars (lugs) internally 17 mm wide and that the curve is suited to a 34.50 mm diameter case. The best aftermarket leather straps are made from alligator, calf or shell cordovan with vegetable tanning and offer multi-year durability.

A high-quality leather strap for the C0252172201700, with premium material (alligator or vegetable-tanned calf), lasts on average 4–7 years of daily use. Durability depends on: frequency of use, climate (humidity accelerates ageing), perspiration and periodic care (cleaning with damp cloth, occasional application of neutral balm). Shell cordovan has even longer durability due to fibre density. A NATO strap lasts 5–10 years thanks to the nature of gabardine fabric. Periodic strap replacement is recommended to maintain the watch in impeccable aesthetic condition without compromising the timepiece's functionality.
