This is an early EH&Co, Series III Model 1862n movement with the balance-over-center-wheel, 3/4-Plate configuration. As described by Dr. Geller: "It has case screws on the dial plate, like the late, Model 1858 divided plate movements that immediately preceded it, and it also retains the late Model 1858 style of pallet bridge. It also features a Lange-style, hanging pin lever escapement, in which a single pin hangs down from the underside of one pallet arm and banks against the edges of a circular depression in the pillar plate. This borrowed idea was Howard's earliest experiment aimed at eliminating adjustable banking pins. The factory records indicate that this movement is fully adjusted to temperature, isochronism and positions, even though the factory did not begin engraving this type of information on watch plates until a few years later, after S# 12,000."

The case is an entirely correct EH&Co made expressly for this style movement - case may be original to the watch. The dial is a scarce Type-3 variety with script signature. Hour and minute hands are likely original; seconds hand is probably a later replacement. Per Geller, approximately 40 1862n models are known to exist.
