I just read the extremely well documented article: Slim is in.
I like slim watches very much (and own 2 vintage thin wrist watches).
I have read that the calibre 1003 was originally (in the 50s) made by Jaeger-Lecoulre. It was (and may be is) common practice of brands to source this or that calibre from the other side of the little swiss valley. Nothing wrong with that (at least in my opinion).
Now the 1003 in the ultra thin 1955 is made at the manfuacture V.C, right?
I love the simple dials and extreme readibility of the dials of ultra thin watches, and I do appreciate their weight on the wrist. One feels nothing yet, one wears a mechanical marvel that ticks very accurately.
