If I'm not mistaken, it's been a long time since your last visit to the Manufacture. Perhaps now is the time to meet up with your friend Jerome again to clear up our questions/concerns.
18 years have passed since the presentation of the Extreme Lab1. I wonder after so many years if there have been any tests in the Manufacture on how the watch performs regarding timekeeping and wear, since the movement is lubrication-free. I wish for an Extreme Lab3. Best
