EARLY E Grade Pocket Watch Jewels

Hello,
I was referred to this forum by a fellow collector.

I have a question about the first E Grade Pocket Watches. I received the current Antiquorum sales catalog and it has the E Grade listed with 17 jewels. I have another book that lists it with 20 jewels. Did they make this model with two different qualities?

Thanks In Advance-

Probably a printing mistake ..

.. as their online catalogue for the New York 10/11 December, Lot 196, lists an "E" grade with 20 jewels. I assume this is the auction you refer to.

By the way their listing that the watch, movement number 5822, was made around 1900 is also clearly incorrect.
