FAQ
What is the lug width of the Certina DS First C0142173605100?
The Certina DS First C0142173605100 features a lug width of 17.00 mm, measured centre-to-centre between the suspension pins. This specific dimension reflects the proportions of the 34.80 mm case and requires straps dedicated to this exact measurement.
What is the best strap for the Certina DS First C0142173605100?
The choice depends on intended use. For formal occasions, we recommend alligator or vegetable-tanned calf leather with mature patina. For sport wear, NATO fabric ensures practicality and reversibility. FKM rubber suits aquatic or high-humidity environments. All our 17 mm straps are compatible with the original lugs.
How do you change straps on a watch with 17 mm lugs?
The operation requires a spring bar tool to extract the elastic pins supporting the strap. Position the tool in the pin groove, press gently downward to release the old strap, then insert the new strap by aligning the holes and pushing the pin until it clicks into place. Avoid forcing: 17 mm lugs are manufactured to precise tolerances.
Is an aftermarket 17 mm strap compatible with the C0142173605100?
Yes, provided the strap is specifically cut for 17 mm lug width. The manufacturing tolerance is ±0.5 mm, so values between 16.5 and 17.5 mm ensure compatibility. Our artisan straps respect these tolerances, guaranteeing a perfect fit without forcing.
How long does a leather strap last on the Certina DS First C0142173605100?
Longevity depends on material and treatment. Vegetable-tanned calf typically lasts 3–5 years with regular maintenance (weekly cleaning, water protection). Alligator, being more resistant, reaches 5–7 years. FKM rubber exceeds 10 years. The natural patina of leather becomes an aesthetic asset, a mark of conscious wear rather than a defect.
