A stunning unique precision regulator with bolt and shutter spring loaded maintaining power, six spoke wheels and counterbalanced asymmetric crutch by James Dalzeil (1798) of Fraserbourgh.
This stunning mahogany case regulator with bombe base has a most lovely proportion being exactly 200cm high. The mahogany veneered bombe base being 49cm at its widest is made from one solid piece. The large single door having two glazed windows for the dial and pendulum.
The very substantial five knopped pillar movement is totally handmade, every hand cut wheel has six spokes and the escapewheel being screwed to its collet and being embraced by 10.5 teeth. The quality of the steel is very good and every pivot and large leaf count pinion has been hardened to a glass hard state. As a feature of quality, the minute wheel (pictured) has a spoke filled in to counterbalance the long fine minute hand. I can confirm that all hands are beautifully made and exquisitely balanced to ensure that the least amount of power is needed. The bolt and shutter mechanism uses an ingenious spring loaded retracting lever to apply just enough power to ensure operation during winding. Another good feature is the perfectly compensated asymmetric crutch with micro-setting adjustment for beat incorporated within the crutch arm. The knife edge shaped crutch pin fits exactly within a corresponding shaped brass part set within the pendulum steel top. This movement has been fully overhauled by me and has been carefully conserved to retain as much original finish as possible. I have polished all brass parts using an age old technique using chalk, Although very labour intensive it gives a finish that cannot be replicated using modern abrasive compounds and ensures that the condition is as close to the original as possible.
The small 1kg brass bound weight is suspended via a lovely six spoke handmade pully with curving spokes, this weight on first inspection looks too small to run this clock however because of the quality of the materials and standard of manufacture of the movement, this is all that is needed to keep the very heavy 10kg pendulum bob oscillating! quite remarkable, from experience the clock is up to the standard of the very fine Austrian regulators that run on very small weights.
The 10inch silvered dial has a lovely patina and has been left as original, there is the odd very fine mark but it does not have the heavy damage around the winding hole that sometimes happens on silvered dials. The incredibly fine hand-cut hands are a delight and the long counterbalance sweep second has no bounce or deviation when it momentarily stops.
I have an original valuation and guarantee from 1993 valuing the clock at 8000 25 years ago! This is a rare opportunity to acquire a totally handmade masterpiece that has been made to the highest of standards of the time and is over 220 years old! The quality of this clock is as good as the stunning Victorian regulators of the late 19th century making this piece unique.
