My view

L' âge d’or du chronographe Longines

A Longines chronograph with caliber 30CH and a French-made 18k gold case from the ’50s, a true jewel of Swiss watchmaking, preserved in perfect condition and never polished.

  • Brand: Longines
  • Model: Chronograph
  • Year: 1955
  • Caliber: 30CH (manual-winding chronograph movement)
  • Case material: 18k yellow gold (750)
  • Diameter: approx. 38 mm
  • Strap/Buckle: Generic
  • Condition: Unpolished
  • History: 1st owner, 1954
  • Working order: fully functional

This rare example is fitted with the legendary caliber 30CH, considered one of the most prestigious chronograph movements Longines ever produced. The dial shows a beautiful vintage patina and has kept its scales perfectly intact.

The solid gold caseback clearly bears the Longines logo, confirming the piece’s authenticity. The movement, visible in the last photo, reveals Longines’ exceptional build quality, with its 18 jewels and its characteristic column wheel.

The caliber 30CH represents the peak of Longines chronograph production in the 1950s, a time when the brand ranked among the most prestigious makers of integrated chronograph movements. This model is particularly sought after by collectors for its technical and aesthetic refinement.

« An honest patina, a legendary movement and solid gold: that is just how I like vintage chronographs. »
