Vintage Heuer Chronograph Repair
At the heart of this repair and service of this Heuer Carrera is the Valjoux 72 movement. Released in the late 1940s, this mass-produced movement has been used in the Rolex Daytona, Breitling Navitimer, and this Heuer Carrera among other high-end chronographs. With a minute and hour counting registers, it has remained one of the most reliable base movements. Even though it technically is an “ebauche” or generic (not an in-house) movement, it is well engineered including such features as a sweep second-hand brake and a quick and reliable reset hammer. Upgrades have included Rolex’s high-end free-sprung balance wheel improving time-keeping precision, as well as an add-on module for day/date/month complication.
Service and repair
Service and repair of this Heuer involved, as always, a complete disassembly, cleaning, and inspection of all parts. Although the watch had been well cared for, minor repairs and adjustments were made to correct areas of wear due to repeated friction in the chronograph section.
