Frequently asked questions

What is the lug width of the Certina DS-1 C006.414.16.051.00?

The lug width is 20 millimetres. Measure precisely by positioning a ruler between the two metal lugs at the attachment points—no approximations. This specification ensures only 20mm straps will fit correctly.

Which strap is recommended for the Certina DS-1 C006.414.16.051.00?

Genuine alligator leather is the preferred choice due to its distinctive geometric texture that amplifies the watch's technical character. Alternatively, vegetable-tanned calf, synthetic NATO, or vulcanised rubber for dynamic use.

How do you change the strap on this watch?

Remove the watch from your wrist and position the case face-down. Use a spring bar tool to carefully push the pins from one side to the other. Never force manually; the movement must be fluid and controlled.

Is an alligator strap compatible with the Certina DS-1 C006.414.16.051.00?

Yes, provided it is certified genuine alligator with lugs measuring exactly 20 millimetres. Natural alligator develops an evolving patina over time, becoming a true companion piece.

How long does a leather strap last on this watch?

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years with regular maintenance and rotation with other straps. Durability depends on usage frequency, humidity exposure, and fibre care.
