Frequently asked questions

What is the exact lug width of the Tissot Touch T047.420.44.051.00?

The lug width of the Tissot Touch T047.420.44.051.00 is 21.00 mm. This dimension is specific to this model and represents the distance between the two spring bar holes protruding from the case lugs. It is essential to measure accurately using a digital calliper, from the outer edge of one lug to the outer edge of the other, to ensure compatibility with aftermarket straps.

Which strap pairs best with the Tissot Touch T047.420.44.051.00?

The Tissot Touch, with its brushed titanium case and touch-sensitive complications, pairs exceptionally well with alligator straps in anthracite-grey or black, which create visual coherence with the metal. For sport contexts, vulcanised rubber in dark grey maintains tactile accessibility and environmental protection. A vegetable-tanned calf leather offers versatility for daily wear and develops natural patina over time.

How do I change the strap on the Tissot Touch T047.420.44.051.00?

To change the strap, obtain a spring bar removal tool or consult a qualified watchmaker. Position the strap on a soft cushion and insert the tool into the lateral gaps between the spring bar and lug, extracting the bar with decisive movement. Repeat on the opposite side. When inserting the new strap, ensure that the spring bars click correctly into their seats—you should feel an audible click from both sides.

Are aftermarket straps compatible with the Tissot Touch T047.420.44.051.00?

Yes, aftermarket straps with 21 mm lug width are fully compatible with the T047.420.44.051.00. However, 21 mm is a relatively uncommon size in mass-market production. MilanoStraps offers a dedicated collection of handcrafted 21 mm straps, manufactured with premium materials including alligator, Italian calf, FKM rubber, and NATO textiles, guaranteeing superior construction quality to standard factory equipment.

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

The durability of a leather strap varies based on tanning method, usage frequency, and storage conditions. An alligator strap with vegetable tanning, worn moderately, maintains full functionality for 5–7 years before requiring leather restoration. A naturally tanned calf develops characteristic patina within 2–3 years of daily wear, maintaining structural integrity for 8–10 years. To extend durability, avoid prolonged moisture exposure, apply a natural leather conditioner every six months, and store the watch in a dry environment.
