“The email address you entered could not be found” is not the response anyone should receive when contacting the representative of a high-end watch company about an expensive watch that failed less than a year after purchase. But it was typical of the level of service I received from Parmigiani Fleurier USA. This is the story of my Tonda 1950 and the long wait to restore it to working order.
The Curious Case of the Column Wheel Valjoux 7750 Variants
I first discovered the world of column wheel 7750 variants while looking at a Longines Heritage Chronograph. The movement looked vaguely familiar to me, yet I couldn’t place it. A bit of research revealed it to be something really special: A column wheel variant of the Valjoux 7753 built by ETA for their Valgranges line. Then I stumbled on the fact that Omega also got a version of this ETA Valgranges A08.L01 movement with a Co-Axial escapement.
