“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.
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.
