Unfiltered opinion:
If we have in our memory some of the gems we found during our activity this came in and took top spot!
So incredibly hard to find a piece like this.
An historically important watch because it was one of the first to use a slide rule in a wrist watch and thus become a true tool watch.
Featuring what has to be the most incredible crystal in all of watch history and this particular “disco volante” style case, with a totally round case with “floating” lugs being so unique, rare and difficult to find.
