Overview

A classic stainless steel automatic wristwatch featuring a sunburst silver dial, applied gold-tone baton markers, and a date window at 3 o'clock. The 'T.12' designation signifies its professional-grade water resistance for the era, housed in a robust case designed for active use.

Story

In 1930, Tissot and Omega merged to form a powerhouse partnership, sharing technology and movements. This T.12 model was their 'all-terrain' champion, built to withstand 12 atmospheres of pressure. The galleon ship on the back isn't just decoration; it's a promise of seafaring durability.

Maker / Origin

Founded in 1853 by Charles-Félicien Tissot and his son, the company pioneered the first mass-produced pocket watch. By the 1960s, they were the 'cool younger brother' to Omega, offering high-precision Swiss movements with more adventurous, avant-garde designs for a globalizing world.

Condition & Value

The dial shows a lovely, even 'champagne' patina consistent with age. The case retains its sharp lines, suggesting it hasn't been over-polished, though the leather strap is a modern replacement. Visible wear on the hands and markers is typical for a 60-year-old daily wearer.

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
