Notes

This watch employs three of Potter?s patents, the details of which are engraved on the bridges. The plate design was patented on January 4, 1875, the escapement and presumably the great wheel design, on October 11, 1875.Albert Potter?s work is not only rare, but always of top quality and offering completely original design.
