For use with a pocket watch
A circular brass table, with a serrated edge, supported by three legs with paw feet, has a bell mounted beneath it. On top, in the middle of the table, is a brass dish covered with green velvet designed to receive an ordinary pocket watch. Above this, a hollow squared arbor (situated so that it can be located on the squared centre arbor of a watch) carries a flag which indexes a star wheel which releases the alarm mechanism at the time set on the silvered setting-disc below.
Attached to the table is a large silver barrel containing the mainspring.
The mechanism is contained in raw mahogany box containing instructions for operating the mechanism pasted inside the lid. Contained in the bottom of the box is an address card, an
advertising pamphlet and a hand-written note by Ilbert.

- Acquisition notes
- The Ilbert Collection of clocks, prints and other related material was destined to be sold at Christie's auction house on 6th-7th November 1958. As a result of the generous donation of funds by Gilbert Edgar CBE the sale was cancelled and the material purchased privately from the beneficiaries of the Ilbert Estate.
Ilbert's watches were then acquired with further funds from Gilbert Edgar CBE, public donations and government funds. These were then registered in the series 1958,1201.
Purchased by Ilbert ca. 1931.
