The Heritage T117.509.11.042.00, seen from the bench

The Tissot Heritage T117.509.11.042.00 is a 27mm stainless steel women's watch from the Heritage collection, featuring a 20mm lug width. It is powered by the ETA 901.001 manual-winding caliber developed in the Vallée de Joux. The dial displays hours, minutes, seconds, and a date window at 3 o'clock. The case combines satined and polished steel surfaces with a transparent caseback revealing the movement. The 20mm lug width requires precise strap compatibility and professional finishing.

Frequently asked questions

What is the lug width of the Tissot Heritage T117.509.11.042.00?

The Tissot Heritage T117.509.11.042.00 features a fixed lug width of 20mm, a dimension determined by the case construction. This measurement represents the internal distance between the lugs and constrains the choice of strap to models specifically manufactured for this width.

What is the best strap for the Tissot Heritage T117.509.11.042.00?

For the T117.509.11.042.00, we recommend alligator or shell cordovan in vegetable tanning for formal wear, as they enhance the sartorial character of the case. For daily use, soft calf or cotton NATO provide comfort without compromise. FKM rubber offers contemporary contrast and moisture resistance.

How do I change the strap on the Tissot Heritage T117.509.11.042.00?

Changing the strap on the T117.509.11.042.00 requires a specific tool (spring bar tool). Insert the tool into the lateral hole of the spring bar beneath the lug, press gently to extract the bar, then remove the old strap. Insert the new strap and repress the bar until you hear the locking click.

Are there aftermarket straps compatible with the Tissot Heritage T117.509.11.042.00?

Yes, artisanal straps measured for 20mm lugs are fully compatible with the T117.509.11.042.00. Ensure the lug width is exactly 20mm and that the strap has been manufactured to this specific width.

How long does a leather strap last on the Tissot Heritage T117.509.11.042.00?

The lifespan of a leather strap depends on the material and usage. Alligator in vegetable tanning: 3–5 years with regular maintenance. Shell cordovan: 4–6 years. Calf leather: 2–3 years with daily use. Regular maintenance (cleaning and conditioning) significantly extends useful life.
