Certina
DS PH C036.407.16.040.00— lug 20mm

The lug width of the Certina DS PH C036.407.16.040.00 is 20 mm. This dimension represents the outer space between the case lugs and determines compatibility with any aftermarket strap. It is essential to verify this measurement before purchasing a strap to avoid incompatibilities.

For the Certina DS PH C036.407.16.040.00, we recommend alligator leather for an elegant-sporty look, vegetable-tanned calf for a patina that evolves over time, NATO for extreme practicality, or FKM rubber for water-based activities. The choice depends on the intended use: formal, daily, or performance.

Strap changing is straightforward: use a spring bar tool to press the small elastic pins positioned in the lugs. Once released, the original strap slides away. Insert the new strap by aligning the spring bar holes with the lugs and press until the pins engage securely with the case.

Yes, any strap with a 20 mm lug width is compatible with the Certina DS PH C036.407.16.040.00. However, verify that the strap thickness in the lug area (approximately 3-4 mm) allows correct adhesion without lateral play or excessive friction with the case.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 2-4 years with daily use, depending on exposure to humidity and perspiration. Vegetable-tanned leather, though less durable than alligator, develops a fascinating natural patina. With proper maintenance (periodic cleaning and protective treatments), longevity increases considerably.
