Strap for DS-8 Lady Quartz Stainless Steel - Yellow Gold / Silver / Bracelet

The lug width of the Certina DS-8 C045.010.22.031.00 is 16mm. This is the internal distance between the two lugs of the case, measured from wall to wall. This width is specific to this model and requires straps constructed precisely to this measurement to ensure a correct fit without gaps or distortion.

The best strap depends on your intended use. For formal and business occasions, we recommend natural brown or black alligator, which enhances the delicate proportions of the 31mm case. For daily wear, vegetable-tanned calf leather in tobacco tones or a neutral-coloured NATO strap offer both practicality and balanced aesthetics. For sports or water activities, vulcanised rubber in grey or blue ensures grip and durability.

Changing the strap requires removal of the spring bars (the metal pins that pass through the lugs). You will need a spring bar tool or dedicated removal tool to free the pin. Once the old strap is removed, thread the new strap by aligning the lugs in the correct position and reinsert the pin until you hear the locking click. We recommend consulting a watchmaker if you lack experience.

Any strap constructed for a 16mm lug width is compatible, regardless of material. This includes alligator, shell cordovan, calf leather, vegetable-tanned leather, NATO straps, fabric, vulcanised rubber and metal. The important thing is to verify that the width is exactly 16mm and that the base thickness does not exceed 3-4mm to avoid tension on the lugs.

The lifespan of a leather strap varies depending on the material, treatment and intensity of use. A high-quality alligator or shell cordovan with vegetable tanning can last 3-5 years with regular use and proper maintenance. A less structured calf leather tends to wear out sooner, approximately 2-3 years. Lifespan increases significantly if the strap is rotated among multiple watches and kept dry, protected from direct sunlight and chemical agents.
