Yeah, the 3120 might be an ordinary workhorse like you say, but how it gained the title of the finest mechanical watch movement? Surely not because it's ordinary..

But only because my AP diver has a solid caseback. Otherwise, it has worked like a charm for the past two years, and hopefully many more! J
