Certina
DS PH C036.407.36.050.00— lug 20mm

The lug width of the Certina DS PH C036.407.36.050.00 is 20 mm. This measurement represents the distance between the two lugs that support the strap. It is essential to verify this dimension before purchasing an aftermarket strap to ensure perfect compatibility with the case.

The Certina DS PH C036.407.36.050.00 offers remarkable aesthetic versatility. For an elegant appearance, we recommend alligator with uniform grain or vegetable-tanned calfskin naturally aged, which emphasise the severity of the ceramic bezel. For sporting applications, a NATO strap in cordura or cold-vulcanised rubber maintains the scientific heritage of the watch without constructive compromises.

To change the strap, you must remove the spring bar pins using a dedicated spring bar tool. Position the tool beneath the pin from inside the case, gently push to compress the spring, extract the pin and remove the worn strap. Insert the new strap by aligning the holes with the lugs, reinsert the pin and verify it is fully locked. We recommend this operation with a professional watchmaker.

Yes, absolutely. The C036.407.36.050.00 with its 20 mm lug width is compatible with any artisanal strap of quality crafted for this width. Aftermarket straps often offer superior materials compared to original equipment, such as authentic alligator, shell cordovan or vegetable-tanned calfskin, allowing you to personalise the watch according to your aesthetic and functional preferences.

The durability of a leather strap depends on material quality, usage and maintenance. A high-quality artisanal alligator or vegetable-tanned calfskin strap can last 5-8 years with regular wear, developing a natural patina that enhances aesthetic value. Organic leather requires periodic aeration, drying after salt water contact and protection from prolonged UV exposure. Vulcanised rubber, although more resistant, tends to degrade after 3-4 years of exposure to chlorine or ozone.
