Really appreciate all info about this. Large 70mm
20 jewel, fast train for 1/10 sec resolution. Maybe for 1948 olympics. Marked
169 on dial. Recently produced gold cased versions selling $65,000. Assume
this one not originally for commercial sale. Like to know age, quantity made, made only for olympics and other Omega events? Collector interest
level enough to be valuable? gold cased expensive model photo added.
