Tissot 6972 Maintenance

The Tissot caliber 6972 is a vintage manual-winding chronograph movement, based on the Lemania 1872. It was produced during the 1970s and featured in various Tissot chronograph models, often co-developed with Omega under the SSIH group. As a mechanical chronograph, the 6972 requires careful handling and regular maintenance to ensure long-term reliability and accuracy.


Basic Maintenance Guidelines for Tissot 6972

1. Service Interval

  • Recommended full service every 4 to 6 years, even if the watch is functioning well.

  • Vintage movements like the 6972 benefit greatly from preventive maintenance to avoid wear from dried lubricants or hardened oils.

2. What a Full Service Includes

  • Complete disassembly of the movement and chronograph module

  • Ultrasonic cleaning of all components

  • Lubrication of key friction points with appropriate modern oils

  • Replacement of worn parts (gears, springs, pivots) if needed

  • Timing adjustment in multiple positions

  • Reassembly and calibration of the chronograph (start, stop, reset functions)

3. Water Resistance Check

  • While many 6972-based watches were not highly water-resistant originally, vintage gaskets often degrade. Replace all seals (crown, pushers, caseback) if applicable.

  • Avoid exposing vintage chronographs to water unless fully restored and tested for water resistance.

4. Handling Tips

  • Avoid over-winding. Stop winding as soon as you feel resistance.

  • Use the chronograph pushers gently. Don’t engage the chronograph while resetting—it can damage the mechanism.

  • Always reset the chronograph after stopping; don’t leave it running indefinitely.

5. Storage

  • Store in a dry, temperature-stable environment.

  • Keep away from magnets and strong shocks (which can affect balance and timing).
