The Touch T110.420.47.051.00 (aka: T1104204705100), seen from the bench

The Tissot T-Touch T110.420.47.051.00 represents a landmark in contemporary Swiss watchmaking: the first tactile timepiece in history, born in 1999. The 45mm titanium and black ceramic case houses the ETA E84.301 calibre, powering a complex movement with perpetual calendar, chronograph, thermometer, and altitude indicator accessible via sapphire touchscreen. The 13mm lug width is specific to this model, requiring dedicated straps. Titanium's lower density ensures lightness despite the generously sized case, while the black ceramic reinforces the 6 o'clock lugs.

Frequently asked questions

What is the lug width of the Tissot Touch T110.420.47.051.00?

The lug width (misura ansa) of the Tissot Touch T110.420.47.051.00 is 13mm. This measurement indicates the distance between the lugs that attach the strap to the case. A 13mm lug width is specific to this model and requires compatible straps with this standard. Accurate measurement is essential to ensure proper fit and avoid gaps or overlaps between the lugs and strap.

Which strap is best suited for the Tissot Touch T110.420.47.051.00?

For the T110.420.47.051.00, alligator leather in vegetable tanning represents the ideal choice: the geometric grain creates dialogue with the titanium, mitigating the technical appearance while respecting its identity. Shell cordovan offers unparalleled durability and natural patina. Vertical-grained calf leather ensures constructive solidity. For sporty, daily use, NATO straps in ballistic nylon honour the model's multi-functional heritage. FKM rubber dialogues directly with the ceramic case, creating material coherence.

How do you change the strap on a Tissot Touch T110.420.47.051.00?

Strap replacement requires a spring bar tool to remove the pins from the lugs. Position the tool in the crescent groove of the pin, push inward and lift gently. The pin retracts, allowing strap removal. Proceed with care: titanium is not fragile, but a 45mm case warrants conscious handling. Reinsert the pins into the new strap, aligning the ends with the lugs and verifying complete locking before wearing.

Can I use an aftermarket strap with the Tissot Touch T110.420.47.051.00?

Yes, provided the strap is designed for 13mm lug width. Aftermarket straps of artisanal quality—such as those in alligator, shell cordovan, or calf—ensure total compatibility with the T110.420.47.051.00, as long as they respect standard pinning. Always verify that the strap ends are correctly dimensioned to accommodate 13mm spring bars. Milano Straps provides a dedicated collection of 13mm straps, tested for compatibility.

How long does a leather strap last on the Tissot Touch T110.420.47.051.00?

Durability depends on material and usage. Vegetable-tanned alligator guarantees 5-8 years with ordinary maintenance; shell cordovan, thanks to natural vitrification, can exceed 10-12 years. Vertical-grained calf offers 3-5 years under moderate daily use. NATO straps in ballistic nylon resist 7-10 years, becoming virtually immortal with minimal care. FKM rubber has limited duration (2-4 years) but is economical and quickly replaceable. The determining factor is protection from excess moisture and direct sunlight.
