DUTCH TABLE CLOCK Adam Heymuys Amsterdam Ca. 1750

Bracket clocks


Signed: Adam Heymuys Amsterdam
Circa 1750

The wonderfully produced bracket clock has an spring-driven double fusee movement consisting of going and striking trains. The going train has a verge escapement with a short pendulum. The Dutch rack striking indicates the hours and half hours fully on two bells differing in pitch. In addition, the movement has an alarm. The striking can be repeated by pulling a string. On the other side of the clock the alarm can be wound, also by pulling a string. The maker has signed the movement on the elaborately scroll-engraved backplate Adam Heymuys Amsterdam.

The arched brass dial has a silvered chapter ring with Roman hour, half-hour, quarter-hour, Arabic five minute and arched minute divisions. In the matted centre is a date aperture, in which the date is shown with black Arabic numerals. The area around the date aperture is embellished with scroll engravings. Behind the blued steel hands is a silvered Arabic alarm disc. The maker has signed the dial at the bottom of the chapter ring Adam Heymuys AMSTERDAM. There is a moon-phase aperture in the arch, which also indicates the moon date. In addition, the time of high water in Amsterdam is shown in a separate aperture above the moon disc. The four corners are embellished by gilt brass scroll and leaf spandrels.

The beautiful burr-walnut veneered oak case of this bracket clock has mouldings on all sides. There are glazed arched doors on the front and the back, whilst the sides have fretted arched sound apertures. The corners are adorned with turned brass finials, whilst the shaped top is surmounted by a brass carrying handle. The clock which rest on four wooden feet has on the front and back side wood-carved crests.

The maker
Adam Heymuys (also Heijmuijs or Nijmuijs) was active as a clockmaker in Amsterdam, and is first mentioned in 1729. He is included in the register of the most important shopkeepers from 1767 as ‘Orlogiemaker op de Nieuwedijk bij de Baafjesweg’ (clockmaker on the Nieuwedijk near the Baafjesweg). There is a longcase clock by his hand in the Rijksmuseum in Amsterdam which is regarded to be one of the most beautiful clocks from the point of view of the case ever made in Amsterdam. Heymuys died in 1766.
