Today I’m returning to one of my favorite watches for “Watch A Day”. This Nivada Antarctic was created to commemorate the company’s accomplishments in exploration, part of the International Geophysical Year, 1957. It’s tiny by modern standards but has a wonderful look to it.
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.
