Strap for DS Super PH500M Stainless Steel / Blue / Sea Turtle Conservancy

The lug width of the Certina DS PH C037.407.18.040.10 is 20 millimetres. This measurement refers to the distance between the metal attachments on the watch case where the strap is fitted. It is essential to order a strap of exactly 20mm to ensure perfect compatibility and correct installation.

For the C037.407.18.040.10, we recommend an alligator strap in cognac brown or shell cordovan for an elegant-sporty profile, or a NATO strap in high-density polyamide or FKM rubber strap for maximum practicality. The choice depends on your intended use: leather for formal occasions, synthetic materials for casual or diving activities.

The C037.407.18.040.10 strap is changed by removing the spring bar pin that connects the strap to the case lugs. Use a dedicated spring bar tool to compress the pin and extract it gently, then insert the new strap by aligning the hole and releasing the pin until it clicks into place. Repeat for both attachments.

Yes, any strap with a 20mm lug width is compatible with the C037.407.18.040.10. Milano Straps offers 20mm straps in artisanal leather, NATO and rubber, customisable according to your aesthetic and functional preferences, guaranteeing construction quality equal to or superior to original accessories.

The lifespan of a leather strap depends on the material, frequency of use and maintenance. A high-quality artisanal alligator or shell cordovan strap typically lasts 3-5 years under normal conditions. Leather naturally develops a patina over time. In prolonged humid environments (regular diving), alternating with rubber or NATO straps is recommended to preserve the leather.
