Strap for 150th Anniversary Automatic Small Seconds

The Tissot Heritage T71.8.440.31 features a lug width of exactly 20mm. This measurement corresponds to the distance between the two vertical lugs on the case and is determined by the original design proportions from the 1950s era. When ordering an aftermarket strap, ensure you select the 20mm version specifically to guarantee a precise fit with no lateral play.

For the T71.8.440.31 in Rose Gold, we recommend a cognac alligator or vegetable-tanned calf leather in dark brown tones. These materials create a warm dialogue with the golden metal, amplifying the vintage character without excessive ornamentation. Alternatively, an anthracite grey NATO offers an elegant contrast for a lighter, more casual aesthetic.

The Tissot Heritage T71.8.440.31 features straight lugs with pin holes. Proceed as follows: (1) place the watch on a soft cloth; (2) locate the two pins positioned on the lugs; (3) use a spring bar tool or fine screwdriver to gently compress the pin from one side until it protrudes slightly from the other; (4) extract the pin with tweezers; (5) remove the old strap; (6) align the new strap's holes with the lug apertures; (7) reinsert the pin until it clicks into position. If you lack the proper tools, consult a qualified watchmaker.

A quality artisanal leather strap on a daily-worn watch typically lasts 3–5 years, depending on perspiration, sun exposure, and cleaning frequency. Vegetable-tanned leather develops a visible patina within 6–12 months, a natural aesthetic result many appreciate. Calf leather requires more frequent maintenance; alligator resists moisture more effectively. We recommend preventive replacement every 4 years for daily-worn watches to avoid unexpected breakage.
