In January I purchased an IWC GST Automatic Chronograph in Titanium from an
established vintage dealer here in the United States. Upon receiving it there
were some condition issues that were not disclosed, which led me to sending it
to IWC for service earlier than I would have liked. I recently just got it
back and its amazing to have this back and in proper working condition, what a
great piece and, in my opinion, extremely undervalued.
I would really love to know what year it was made, however; that is difficult
to do unless I get a certificate of authenticity from Schaffhausen directly.
Ironically, I said I wanted this with my service request, but this was sent to
Richemont service center in Houston, Texas. They offered to send to
Schaffhausen post-service, but this had already taken three months and I was
very eager to get it back.
That being said, I recently noticed something that seems to set my GST apart,
and that is the case back. On every other GST I see the case back has an
engraving on the center portion that reads _International Watch Co.
Schaffhausen, _however; my case back is completely blank (aside from the
serial number of course). I have attached a photo that shows this. In digging
a little deeper I referenced the original manual and service/guarantee booklet
that came with my watch, and on the manual it had the following text on the
back booklet page "A04783/7.97". What immediately caught my eye was the 7.97
portion, is that a revision reference of the manual, meaning July of 1997? If
that is the case then my example may be a very early GST, potentially first or
second year of production. Is anyone aware of how my GST's age can explain my
blank case back? Is this an indication of a service replacement from the past?
Enjoying doing some detective work, hoping there may be some other answers!
