Strap for DS PH200M Stainless Steel / Black / NATO

The lug width of the Certina DS PH C036.407.16.050.00 is precisely 20 mm. This dimension is measured using a digital calliper positioned between the spring bar lugs. It is essential to verify this specification before purchasing any aftermarket strap, as even a minimal deviation renders the strap incompatible.

For the Certina DS PH C036.407.16.050.00, coloured alligator straps (navy, dark brown) are ideal for formal elegance, vegetable-tanned calf leather for aesthetic longevity, NATO in technical fabric for versatility, and vulcanised or FKM rubber for diving use. Your choice depends on primary use and the maintenance time you wish to dedicate to the material.

Remove the spring bar pins using a dedicated tool (spring bar tool), applying firm yet controlled downward pressure on one side. Once the pins are extracted, slide off the old strap and insert the new one, ensuring the pins are correctly positioned in the lugs. Verify that the strap is securely fastened by pulling gently in both directions.

A high-quality leather strap with vegetable tanning has an average lifespan of 3–5 years with moderate daily wear. Longevity depends on wearing frequency, exposure to moisture and heat, and maintenance (periodic cleaning and conditioning). Alligator or shell cordovan straps tend to last longer owing to the more robust fibre structure of exotic hides.
