Hello People,
A few weeks ago, i saw a Caliber 70 on Ebay. I liked it a lot, so i bought it.
Now, i have the following question. It is a model from 1945, the first year of
production (3800 from the total 4500 a year later).
The backplate is not marked. Maybe it is changes over the years, but it seems
original to me. Does IWC always mark the backplate? Also in the early 40's?
