Overview

A classic 1970s stainless steel sports watch featuring a striking 'vignette' or 'dégradé' blue sunburst dial. This model represents the 'Space Age' design era where watch cases became more geometric and dials…

Story

In the early 1970s, the watch world was undergoing a radical transformation as stainless steel became the most fashionable material for a luxury timepiece.

Maker / Origin

Founded in 1853 in the Jura Mountains of Switzerland, Tissot has a long history of technical firsts, including the first mass-produced pocket watch.

Condition & Value

The acrylic crystal is heavily scratched, which is common for this era but obscures the beautiful dial. The stainless steel case and bracelet show significant surface wear and 'desk diving' marks.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

▲ Strong maker attribution with credible period details
▲ Better-than-average condition for the category
▲ Broader demand rises when presentation and finish feel intact

Concerns

▼ Decorative-only demand limits the ceiling
▼ Surface wear or missing provenance can compress the range fast
▼ Regional sale lanes often underperform specialist venues
