Strap for Chemin Des Tourelles Powermatic 80 34 Stainless Steel / Silver / Bracelet

The lug width is 18mm. This measurement represents the distance between the two attachment points of the strap to the case. Precise measurement is essential for acquiring compatible straps: position a ruler from the centre of one attachment to the other, excluding the metal pins. The 18mm lug width is characteristic of classical models with 34mm cases and emphasises the original harmonious proportions of the timepiece.

The choice depends on intended use and aesthetic preference. For consistency with the vintage spirit of the model, we recommend vegetable-tanned leather (brown, tobacco, black): it ages naturally and acquires patina over time. Polished alligator confers impeccable formality, ideal for professional occasions. NATO straps in canvas or nylon maintain balanced proportions thanks to the 18mm lug width, perfect for a sporty-elegant daily approach. For humid environments or water contact, FKM rubber ensures durability without aesthetic compromise.

Procure a spring bar tool or small flathead screwdriver. Position the watch on a soft surface (cotton cloth) to prevent scratches. Locate the attachment pins at the ends of the lug (18mm). Gently push the pin towards the opposite side, pressing lightly to release the strap. Repeat from the other side. Insert the new strap by aligning the holes with the pins, then push until locked. Verify that the pins are fully inserted before wearing the watch.

Yes, provided the lug width is exactly 18mm. Many high-quality aftermarket straps from specialised artisans fit the Tissot Chemin Des Tourelles T139.207.11.031.00 perfectly. Verify technical specifications with the vendor before purchase. Leather, NATO, rubber and alligator straps from specialist manufacturers maintain original aesthetics whilst offering choice versatility. The stainless steel case accepts any material without compromise.

Longevity depends on tanning method and usage. Vegetable-tanned leather resists 18–36 months with daily wear and moderate maintenance (protection from excessive moisture, natural air-drying). Satin calf and alligator offer similar or superior longevity (24–48 months). Regular maintenance—cleaning with a damp cloth, application of specialist balms every 3–4 months, natural air-drying—significantly extends service life. Vegetable-tanned straps age with elegance, acquiring precious patina. The 18mm lug width of the T139.207.11.031.00 favours balanced wear, reducing mechanical stress on the band.
