Made to Measure

The strap for this watch is made to measure

On the Certina DS-1 the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

How do I change the strap on the Certina DS-1 C0062071103100?

Strap replacement is performed using a spring bar tool. Gently remove the elastic pins at the lug ends, extract the old strap, insert the new one ensuring correct alignment, and secure the pins. Consult the manufacturer's manual for detailed procedures or contact an authorised service centre.

How long does a leather strap last on the Certina DS-1?

A quality leather strap (crocodile or vegetable-tanned calf) typically lasts 5-7 years with regular use and proper maintenance. Natural ageing is not deterioration but patina development. Avoid prolonged exposure to salt water and extreme humidity, and dry promptly after accidental liquid contact.
