Some super cool Hammy's

#1 Post by Nookster » Tue Jun 19, 2018 7:48 am

I was recently looking for a Jump Hour tiffany, and ran across this. I was told these were from the estate of John Gelson and went to auction recently. I missed the auction

These two prototype jump hours sold for $2,700..

Salesman Sample, sold for $2,091. I own a few of these but 980's.

$3,075 for this prototype Calendar movement and dial.

Super cool for sure!

That jump-hour Illinois looks like an earlier draft of the watch Fred shows on p. 332 of the new book. The one in the book is a complete watch, and the colors of the metal are reversed from this one: yellow gold outer bezel with sterling silver plate in the dial opening. Did the auction listing say what the metals were for this watch? The watch in the book also has decorative engraving on the dial plate. I notice that the Illinois has rotor seconds, something they were known for, while the Hamilton does not. The illinois case seems to be based on that of the Baronet.

Fred's watch also seems to have come from the Gelson estate.

Love the design on both of those, and I agree about the similarity with the Baronet.
Too bad they never made it production.

I need to correct myself about the colors of the watch on p. 333 of the book. On closer examination of the source image, I see that the bezel is, like the one Nookster posted, white, and the dial plate is yellow. But are white trim arches as overlays on the yellow, and it was the color of these that threw me off. Perhaps Fred can post a larger picture than the small one that he was able to wedge into the book at the last minute.

I should have added that the case is YG and Sterling Silver.

Thanks again,

Yep, very cool.

Out of interest, were these prototype designs made in such a way as to have a crystal over the top to keep dust etc from the movement?

Only, from looking at the Hamilton jump hour, which I assume is sharing the same case as a Webster, I can't see how such a crystal could have been fitted, and surely without one the movement wouldn't last very long?

The crystal on jump-hour watches of this era (Bulova, among others, actually had them for sale) is typically a thin sheet of flat glass under the flat bezel.

It looks like they bezels are where the glass crystals went and thy just replaced it that way and glued it on, or affixed it some other way.

Is the one a jump-hour Webster?
