The Chemin Des Tourelles T139.807.36.031.00 (aka: T1398073603100), seen from the bench

The Tissot Chemin Des Tourelles T139.807.36.031.00 is a 39 mm manual-winding watch featuring an ETA caliber C07.111 movement and a 316L stainless steel case. The dial displays applied indices in Super-LumiNova, lance-shaped hands, and a date window at 3 o'clock. With a 20 mm lug width and 50 meters water resistance, this model emphasizes balanced proportions and functional design rather than nostalgic revival.

Frequently asked questions

What is the lug width of the Tissot Chemin Des Tourelles T139.807.36.031.00?

The lug width of the Tissot Chemin Des Tourelles T139.807.36.031.00 is 20 millimetres. This specific width requires dedicated straps, not universal ones. To measure correctly, position a calliper between the two lugs at the innermost point, excluding gaskets or adhesives.

Which strap is best suited to the Tissot Chemin Des Tourelles?

For the anthracite grey dial of this model, we recommend a vegetable-tanned alligator in cognac or medium brown, or shell cordovan for those desiring natural ageing patina. High-quality vegetable-tanned calf represents the ideal compromise between quality and versatility. For casual contexts, a biological NATO or natural Vibram rubber adds practicality whilst maintaining visual character.

How do I change the strap on the Tissot Chemin Des Tourelles T139.807.36.031.00?

The strap is changed by extracting the pins (splines) positioned laterally on the lugs. Use a dedicated tool (spring bar or pin remover) to gently withdraw the pin from its seat, applying leverage from bottom to top. Avoid sharp tools that could scratch the case. The new strap must be exactly 20 millimetres in lug width to ensure correct fit and stability.

Can I use a 20mm aftermarket-compatible strap on this Tissot?

Yes, provided the strap is specifically constructed for a 20 millimetre lug width and meets technical specifications. Straps from specialist suppliers (such as those offered by Milano Straps) guarantee compatibility, secure fastening, and superior construction quality compared to generic products. Always verify that the strap lugs are correctly dimensioned for the Chemin Des Tourelles case.

How long does a natural leather strap last on a watch like the Chemin Des Tourelles?

A high-quality leather strap (alligator, vegetable-tanned calf, or shell cordovan) under moderate daily wear typically lasts 3-5 years. Ageing is a characteristic, not a defect: the patina that forms documents use and imparts individuality. Longevity depends on exposure to humidity, temperature, and frequency of wear. Periodic maintenance (cleaning and conditioning) significantly extends strap lifespan.
