Strap for Chemin Des Tourelles Powermatic 80 34 Stainless Steel / MOP

The lug width of the Tissot Chemin des Tourelles T139.207.16.111.00 is 18 mm. This measurement is critical for selecting compatible straps: the strap ends must measure exactly 18 mm in thickness to fit correctly into the case lugs. Use a ruler or calliper to verify the measurement with precision.

The most suitable strap depends on your intended use and aesthetic preferences. For formal elegance, we recommend alligator or calf leather with vegetable tanning, which enhance the case's classical design. For daily versatility, a calf strap in brown or black with a deployant clasp offers comfort and practicality. NATO straps are ideal for casual-sport styling in warmer months. The 18 mm width ensures full compatibility with any strap of this dimension.

To change the strap, you have two options: (1) use a springbar tool by inserting the lever into the lateral spaces of the case to lift the springbar, or (2) visit a professional watchmaker who will complete the operation in minutes. The springbar is the small metal pin that holds the strap in the case lugs. Once the old strap is removed, insert the new one ensuring the strap is centred and the springbar is fully seated in the attachment holes.

Yes, you can use aftermarket straps from any manufacturer provided they measure 18 mm in lug width. Milano Straps produces artisanal straps in premium leather, rubber and technical textiles, all compatible with this reference. Using alternative straps does not compromise case integrity and permits complete aesthetic personalisation without voiding the Tissot warranty (unless the case itself is modified).

The lifespan of a leather strap depends on material, usage and maintenance. An alligator or shell cordovan strap of artisanal quality lasts 3–5 years with daily wear if maintained periodically (cleaning, conditioning). Vegetable-tanned calf leather has similar longevity but develops an ageing patina that enhances its aesthetic value. Rubber straps last 5–7 years. Replacement is straightforward, so you can rotate straps to extend the life of each and adapt to seasonal changes.
