Frequently asked questions

What is the lug width of the Certina DS First C0144072208100?

The lug width of the Certina DS First C0144072208100 is 18 millimetres, measured between the two inner attachment pins. This dimension offers compatibility with numerous artisanal and industrial straps, making it a standard width in the sports-elegant category.

Which strap is most suitable for the Certina DS First?

Selection depends on intended use: for formal elegance, we recommend shell cordovan with vegetable tanning or black alligator with deployante. For daily versatility and water resistance, a NATO strap in Cordura or FKM rubber is ideal. On dark grey dials, prefer dark brown or black tones; on black dials, bold colour options (burgundy, navy blue) are appropriate.

How do you change a strap on a watch with 18mm lugs?

Position the watch on a soft surface. Use a spring bar removal tool: insert the flat end into the lateral slot of the pin, apply gentle inward pressure, remove the old strap. Insert the new strap by aligning the holes with the pins, press until the spring bar clicks into place. Verify that both attachments are secure.

Is an aftermarket strap compatible with the Certina DS First C0144072208100?

Yes, provided the lug width is 18 millimetres. All artisanal and industrial straps designed for this measurement (alligator, calf leather, NATO, rubber) fit the Certina DS First perfectly. Always verify that the attachment holes align with the case lugs.

What is the lifespan of a leather strap on a wristwatch?

A quality leather strap under moderate daily use (5–6 days weekly) has an average lifespan of 4–6 years. Humid environments (shower, swimming) accelerate ageing. Vegetable-tanned leathers develop patina naturally and remain functional beyond 7 years. FKM rubber and Cordura NATO straps easily exceed 10 years without structural failure.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
