I am about to attempt a restoration on a very large watch - 5.1 cm plate diameter + 6.2 cm dial damenter - perhaps a small clock or pedestal mounted watch. Immediately acertainable particulars are ...

Knickerbocker Watch Co - 7j, 2 position adjusted, St Imier, Switzerland + New York USA, per plate engravings; dial markings = Excelsior + Swiss.
This all prior to any disassembly which must await completion of other projects.

Preliminary exam indicates particular need for replacement of both rachet and transmission wheels as beyond my in house capabilities and in need of supply source..

Can anyone help in identification of this sinker or parts availability.

Regards + thanks + Happy New Year to all.

Henry

Knickerbocker Watch Co.
New York, New York
1890-1930

This company imported and sold Swiss and low-cost production watches.

The largest one listed in my book is 18s,7j,ps,ni,duplex escapment. The smallest being 6s,Duplex

I don't know of any suppy sources for these, but someone else might.I hope that the information was usefull.

Henry, Can you post a pic of the movement? This would help us to know what you need. Knickerbocker got their US made watches from New England Watch Company. These had a duplex escapmentment. If your watch is one with a duplex escapement, and there is a problem with the staff or escapement wheel, it will be extremely difficult to restore. There are very good, experienced watchmakers who will not touch these. If you can show a pic, we can see if yours is a New England or a Swiss made movement.

Hi Frank:

Many thanks for the comeback - interest greatly appreciated.

This clunker is over 2-1/4 inches in diameter and beyond anything listed historically for Knickerbocker - it almost appears intended to be mounted pendant tube down on a shaft or pedestal, as though in an automobile, on a piece of machinery, or the like. I will attempt to photograph and post.

Regards,

Henry
