chocosa - that's a lovely piece - thanks for showing it again. This thread is so massive that it's easy to miss a lot of worthwhile stuff.
Rooster - I won't know the exact age untill I have it opened and the serial number cross-referenced with Omega records. The watch was certainly marketed by the most recent vendor as being original - and though there is nothing about the watch which suggests the contrary to me, I always retain a bit of skepticism given the number of decades and unknown owners that have passed since it was made.
Not sure of the thickness (and I have misplaced my calipers) but being a manual wind, it is very slender indeed.
Thanks RP. It looks great.
