Strap for DS First Lady Ceramic Black

The lug width of the Certina DS First C0142351705100 is 18mm. This measurement represents the distance between the two lugs on the case where the strap attaches. Accurate measurement from the inner side of the lugs is essential to ensure the new strap fits perfectly without lateral movement or pressure on the case.

For the Certina DS First C0142351705100 in ceramic and stainless steel, recommended options include: vegetable-tanned alligator for classical elegance, shell cordovan for colour evolution over time, cotton-nylon NATO for contemporary practicality, and FKM rubber for technical resilience. The choice depends on intended use and desired chromatic contrast with the ceramic bezel.

To change the strap on a Certina DS First, use a spring bar tool to extract the spring bars from the lug holes. Position the tool in the lateral groove of the spring bar, apply gentle pressure to compress the spring, and remove the old strap. Insert the new 18mm strap, aligning the holes with the spring bars, and verify that the strap lugs are firmly positioned on both sides of the case.

Yes, any strap with an 18mm lug width is compatible with the Certina DS First C0142351705100. High-quality aftermarket straps in full-grain leather, shell cordovan, alligator or technical rubber fit perfectly thanks to standard spring bars. We recommend choosing straps from specialist suppliers who guarantee precise finishing and material stability.

The lifespan of a leather strap depends on usage and maintenance. A full-grain leather or shell cordovan strap, when worn regularly with seasonal rotation and proper care (gentle cleaning, conditioning with neutral oils), typically lasts 3–5 years. Constant exposure to perspiration, water and sunlight accelerates deterioration. Cotton-nylon NATO straps have greater durability, whilst FKM rubber resists deterioration for over 5 years if protected from extreme temperatures.
