Ref: 803

£14,500.00

James Aitchison is listed as a “watchmaker, jeweller and silversmith” in the Scottish Post Office Directory of 1867

A fully skeletonised weight driven movement with 6 spoke wheels and high count pinions.

The fancy scrolled brass plates are of very robust construction with 6 knopped and double screwed pillars.

The dead beat escapement has extremely unusual and decorative convex pallet arms, with beat adjustment on the crutch and the barrel has Harrisons maintaining power.

The slab sided driving weight has an integral pulley and falls to the side of the case via a roller.

The separately suspended pendulum has a beautifully constructed steel and brass frame to the glass jar with mercury compensation.

There is an ingenious method of rating adjustment by means of a purpose built key that acts on the threaded beat spike which also has a turned brass locking bolt - a feature not seen on any other clock

This most decorative of clocks could well have been his shop regulator to demonstrate his obvious skills to passing trade.
