Frequently asked questions

What is the lug width of the Tissot T-Pocket T866.410.99.013.01?

The lug width of the Tissot T-Pocket T866.410.99.013.01 is 20mm, measured between the two lugs soldered to the case. This dimension is standard for pocket watch category timepieces and allows the use of a wide range of compatible aftermarket leather straps.

What is the best strap for the Tissot T-Pocket T866.410.99.013.01?

For the T-Pocket T866.410.99.013.01, we recommend an alligator strap with vegetable tanning, in cognac brown or slate grey, to respect the classical vocation of the palladium case. Alternatively, warm cognac calf leather or shell cordovan that evolves chromatically over time offer elegance without aesthetic compromise.

How do I change the strap on the Tissot T-Pocket T866.410.99.013.01?

Strap replacement requires a specific tool (spring bar tool) to release the lug terminals from the case. Position the tool in the tension spring groove, gently lift until the spring retracts, then extract the terminal. Insert the new strap by reversing the procedure. For models with non-standard integrated lugs, we recommend consulting a specialised watchmaker.

Is an aftermarket strap compatible with the Tissot T-Pocket T866.410.99.013.01?

Yes, any strap with a 20mm lug width is compatible with the T866.410.99.013.01, provided the passants are shaped to accommodate a lug thickness between 2.5 and 3 millimetres. Our artisanal 20mm collection straps have been verified for mechanical and aesthetic compatibility with this Tissot reference.

How long does a leather strap last on the Tissot T-Pocket T866.410.99.013.01?

The lifespan of a leather strap depends on the tanning method, material quality and intensity of use. An alligator or shell cordovan strap with vegetable tanning lasts an average of 5-8 years with daily wear. Calf leather offers 3-5 years. Regular maintenance (cleaning, conditioning with specific creams) significantly extends the strap's lifespan.
