I know the problem.  I inherited a watch from my grandfather some 25 years ago.  It would date back to the 1950s or early 60s.  It is an Alpinex Deluxe, 17 Jewel Incabloc, Swiss Made.  On the back of the case is enscribed Compressor Brevet 313813, then the numbers 0801 and 5333, Swiss Made, Stainless Ssteel Back, Waterproof Incabloc.

I know that my grandfather did not by cheap watches, so it is a reasonable assumption that this is a very good watch.  It is in excellent condition and has recently been repaire/ refurbished.

If you find out anything please let me know.
