The Whitney came in either a 14K yellow or white gold filled case. Depending upon the year, buyers could select from either a luminous dial or an applied gold numeral dial - although the latter was called a Raised Gold Figure (RGF) dial.
The Whitney is notorious for wear through on the bezel and case due to the prominent features of the unique stepped-case design.
Behind the dial is a 6/0 size 17 jewel 987-F movement. The 987F is identical to the 987 movement, excepted the jewel settings are held in place with Friction, instead of screws. Otherwise all of the other parts are the same.
I recently has a friend send me his "new" Whitney. It wasn't running and he needed some help. It was in great shape, otherwise.
A close up of the movement revealed that it was bright and shiny. I can normally tell a serviced movement by the brilliance of the gold-colored jewel settings (chatons). They seem to be a good litmus test for cleanliness. These chatons look great.
When I looked at the front of the watch, I noticed the second hand was up against the dial... so much so that the watch had stopped. I lifted the second hand up a little and off the watch went running. In fact, it was running so well that I don't think I could get it any better.
The inside of the case back appears to say GS May-13 so maybe it was serviced last year? Or maybe it was May 17 this year?
This Whitney is awesome - I wish it was mine but, alas, it has to go back to it's rightful owner.
