Overview

A classic Swiss-made stainless steel timepiece featuring a deep navy blue dial with luminous gold-tone accents and a date window at 3 o'clock. This model is part of the iconic PR 100 series, designed to be a versatile 'sport-chic' watch that transitions from professional settings to outdoor adventures.

Story

Launched in the 1980s, the PR 100 line was Tissot's answer to the demand for a watch that was both elegant and indestructible. The 'PR' stands for 'Precise and Robust,' a promise backed by its 100-meter water resistance.

Maker / Origin

Founded in 1853 by Charles-Félicien Tissot and his son in Le Locle, Switzerland, Tissot has a long history of innovation, including the first mass-produced pocket watch. They are the official timekeeper for the NBA and Tour de France, cementing their legacy in high-performance precision.

Condition & Value

The watch shows honest wear consistent with daily use, including light scuffing on the stainless steel bezel and bracelet. The sapphire crystal appears remarkably clear, which is a testament to its quality. Visible wear on the bezel's high points slightly reduces value compared to 'New Old Stock' examples.

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
