Pair cased calendar verge with moon phase dial

Stock No. 1530

Alexander Cambell
London, c1780
Gilt pair cases, 55 mm
Verge escapement


An interesting and very rare calendar verge, with moon phase subsidiary dial.

MOVEMENT : Gilded verge escapement, with the balance cock nicely engraved with a portrait. Silver regulator disk and blued screws. Four round pillars.
The movement has a stop watch function, with lever on the dial at 2 allowing the watch to be stopped and restarted.

Signed “Alex Cambell, STRAND, LONDON” and numbered (149).

The movement is in excellent condition and is running well, including the stop/start mechanism.

DIAL : Wonderful original white enamel dial, with centre seconds, and 3 subsidiary dial. The hours/minutes at the top, standard 31 day calendar at the bottom left, and a moon phase calendar at the bottom right. The moon phase subsidiary dial shows 29.5 days, the average time of a moon cycle.

In good condition, with just two very light hairlines (from the centre of the calendar dial, towards 11, and a very short one from the centre of the moon dial). A few surface scratches but no repairs.

Fine matching gold coloured hands which appear to be original. Repairs to the hour and seconds hands.

Both calendar hands are turning correctly and all of the motion wheels are present.

INNER CASE : Gilded brass with maker’s mark WH.

Reasonably good condition though the stem has been reattached and there is wear to one of the hinge sleeves. The bezel snaps shut correctly. Wear to the gilding

The very high dome bull’s eye crystal has a few light scratches and a small chip, right on the bezel at 7.

OUTER CASE : Gilded brass, with maker’s marks matching the inner.

In good condition, with just wear to the gilding. The hinge, catch button and catch are fine and the case snaps shut nicely.

Alexander Cambell is listed in London from before 1772 until about 1800.
