Strap for Entrepreneur One Stainless Steel / Anthracite / Strap

The lug width of the Tissot Heritage T66.1.423.61 measures 20 mm, measured inner-to-inner between the two case lugs. This dimension is standard across all Heritage models from this generation and is essential when selecting a compatible strap.

We recommend a calf leather strap with vegetable tanning in dark brown or saturated black for the Tissot Heritage T66.1.423.61. Alternatively, bordeaux shell cordovan maintains the watch's formal elegance. Vulcanised rubber straps suit intensive daily sportive use, whilst NATO straps remain inconsistent with the watch's constructive rigour.

Place the watch on a soft surface. Use a spring bar tool to compress the spring bar from inside the lug. Extract the metal bar from the holes in the case and slide off the old strap. Reinsert the spring bar into the new strap and seat the bar in the case holes until you hear a click.

Any quality strap with a 20 mm lug width is compatible with the T66.1.423.61. Ensure the spring bar is intact and the strap thickness does not exceed 3 mm at the attachment point to avoid pressure on the case. Avoid inexpensive straps with chrome plating, which corrode the brushed steel rapidly.

A quality artisanal vegetable-tanned calf strap typically lasts 3-5 years of moderate daily wear, developing a natural patina over time. Shell cordovan can last up to 8 years due to the density of horse fibre. Longevity depends upon exposure to moisture, perspiration and extreme temperatures. Periodic maintenance with colourless balm significantly extends lifespan.
