The strap for this watch is made to measure
On the Certina DS Prime 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.

How do I change the strap on the Certina DS Prime C0043101111700?
Strap replacement requires a specialised tool: a spring bar tool or lug lever. Position the tool beneath the metal spring that secures the lug, apply gentle downward pressure to release one end, then fully extract the spring. Insert the new strap under the lugs, reposition the spring ensuring it is centred, and verify the lock engages properly. If unfamiliar with the procedure, we recommend having the replacement performed by a qualified watchsmith.
How long does a leather strap last on the Certina DS Prime C0043101111700?
A quality leather strap, finished with vegetable tanning, typically lasts 3-5 years with daily wear, provided proper maintenance is observed: avoid prolonged water exposure, dry promptly if wet, and periodically apply a natural-based protector. The ageing process creates a patina that enriches aesthetics, whilst mechanical wear at the lugs represents the most common durability limit. An FKM rubber strap endures 5-7 years with superior performance in challenging environments.
