This is a large watch at 43mm with multiple functions in the perpetual calendar.  It has an automatic movement with 3 shock resistant features.

It is an insanely complicated watch that can read the day or date in the future.  

It comes with a rare brown/bronze dial that has a sunburst feature when looking with the naked eye.  A really nice lookign dial.  It comes with the original Orient steel strap that is tapered to match the watch perfectly.  It has a scratch on the left side of the glass case that will come out, but I have not attempted it as it does'nt spoil the watch enough to start remedial work.
