Best Watch Straps for the Tissot Heritage 1973 Chronograph
In 1973, Tissot produced a tonneau-cased chronograph that represented the brand's most direct expression of its motorsport identity — a Valjoux-powered automatic chronograph with a perforated leather strap that Tissot had themselves invented and patented in the 1960s. The strap's large perforations referenced the leather-wrapped steering wheels of racing cars of the era: ventilated leather designed to maintain grip through perspiration during competition. The watch was not a celebrity endorsement piece or a limited-edition marketing exercise. It was a working instrument produced during the height of Swiss motorsport watchmaking culture.
The modern Tissot Heritage 1973 Chronograph is a reissue of this specific watch — the same tonneau case shape, the same three-register chronograph layout, the same perforated leather strap. Tissot produced the first modern Heritage 1973 as a limited edition of exactly 1,973 pieces, and subsequent versions have continued the motorsport partnership with Kessel Classics, a vintage racing team whose cars race in the same events that the original 1973 Tissot would have occupied a wrist at.
The Heritage 1973's case is a tonneau — oval or barrel-shaped rather than round. This is significant for strap choice: the tonneau case has curved lug walls that suit leather with flexibility and drape rather than very stiff constructions.

The Perforated Factory Strap — What Tissot's Own Choice Says
Tissot ships the Heritage 1973 on a perforated leather strap as standard across every reference. This is not merely a styling choice — it is a historical reference. Tissot invented and patented the large-perforation leather strap in the 1960s specifically for motorsport use: ventilated leather for racing driver wrists. The perforations allude to the steering wheel leather of 1973-era racing cars. When Tissot ships the Heritage 1973 on perforated leather, they are referencing their own original patent.
Best Leather Straps for the Tissot Heritage 1973
Brown vintage two-stitch calfskin at 20mm — the most celebrated and most historically resonant Heritage 1973 combination. The warm brown and two-stitch construction reference the 1973 era directly — the worn leather of 1970s motorsport culture, the paddock equipment, the leather jackets, and the racing car interiors of the era the watch celebrates. Tissot itself ships the Heritage 1973 on warm brown leather across multiple references, confirming this as factory-validated. On the blue or silver panda dial, warm brown leather creates the most discussed Heritage 1973 aftermarket pairing.
Classic flat calfskin in dark brown at 20mm — the most versatile everyday leather, following Tissot's factory brown leather choice in full-grain calfskin.
Classic flat calfskin in black at 20mm — the most formally correct Heritage 1973 combination. The non-stitch variant is the most minimal — particularly effective on the black dial T124.427.16.051.00 where the all-black palette creates a purposeful monochromatic combination.
Tan suede at 20mm — the most relaxed leather option. Tan suede references the worn leather of 1970s motorsport equipment in a warm, casual register. Particularly effective on the silver panda dial.
Dark brown suede at 20mm — for smart-casual contexts.
Navy calfskin at 20mm — for the blue dial T124.427.16.041.00. Navy leather on the blue dial follows the factory colour logic in a quality leather that develops genuine character.
Burgundy calfskin at 20mm — a distinguished formal alternative.
Thickness note: The Heritage 1973's tonneau case has curved lug walls. Flat and moderately padded leather at 2-4mm suits the case proportionally. Very thick padded leather at 5mm+ creates a visual height imbalance relative to the 14.8mm case thickness.
Best Rubber Straps for the Tissot Heritage 1973
The Heritage 1973's 100m water resistance makes rubber appropriate for active daily wear.
Tropical style FKM in black at 20mm — the most collector-appropriate rubber combination. The vintage basket-weave pattern references the 1973 era of the watch's design origin — the same decade's dive watch and motorsport equipment rubber culture.
Brown tropical FKM at 20mm — for the most warm vintage character. Particularly effective on the panda and blue dial variants.
Classic FKM rubber in black at 20mm — the most practical active choice.
Best Nylon Straps for the Tissot Heritage 1973
Single-pass nylon — Original at 20mm with the CNS solid buckle. Most appropriate Heritage 1973 colourways:
- Olive / khaki — for the most vintage motorsport and racing world-adjacent character.
- Black — the most minimal and most operational.
- Black and grey — the most understated collector combination.
- Navy — for the blue dial variant.
RAF single-pass nylon at 20mm — for the most specifically British motorsport heritage combination. The RAF strap's 1954 British service heritage connects to the same British motorsport world the Heritage 1973's design references.
Canvas at 20mm in olive or black — for a specifically vintage racing character.
Marine Nationale elastic at 20mm — the most comfortable daily wear option.
