Two things to get excited about. First, this is the only pocket watch
I've seen with "JR" and "East" printed on the dial. Tiny, almost
microscopic letters, in green.
Second: note the small number on the case back. 314367 means that this
watch was manufactured in January 1993 and it was number 4367 of that
model. Now, it happens that this is also Andrew's birth month and year,
so I made the suggestion a few years ago that he should buy this watch
off me because birth year watches are generally hard to find. He took
the watch with it's display stand, set it exactly to atomic clock time,
and parked it on his work bench - then the both of us forgot about it.
Today, Andrew checked the time on 'his' railway pocket watch: since
December 2019 it only lost 5 seconds!! This is simply unbelievable.
Surely, the watch was in a stationary position, and kept in constant
temperature, but nevertheless, this is a true testimony to the
performance of Seiko's 7C11 standard grade quartz movement.
