AMSTERDAM LONGCASE CLOCK
Signed: Isaac Hasius Haarlem
Circa 1690
The Netherlands

Movement
The weight-driven, eight-day movement is constructed between brass plates and consists of going and striking trains, as well as alarm. The going train has anchor escapement with seconds pendulum. The Dutch quarter-hour striking train indicates the hours and half hours fully on two bells differing in pitch with two hammers. The quarter hours are indicated with one stroke. The striking is regulated by an internal count wheel.

Dial
The black velvet covered square brass dial has a silvered chapter ring with Roman hour, half-hour, quarter-hour, Arabic five-minute and minute divisions. The centre has a date aperture above the VI and a silvered brass seconds ring below the XII. The two winding holes are situated left and right of the middle and just below the level of the III and IX. The maker has signed the clock at the bottom of the chapter ring, Isaac Hasius Haerlem. The corners are embellished by four elaborate silvered cast brass spandrels depicting cherub heads. The time is indicated by an extremely fine period pair of pierced and engraved brass hands. Behind the hands is a silvered brass alarm disc for setting the alarm.

Case
The walnut-veneered oak case has a rectangular trunk door with glazed oval lenticle set in a wooden surround and is framed by stepped mouldings. The hood has mouldings at the top and bottom, and a frieze with silk-backed pierced wooden sound apertures. The glazed hood door is flanked by two barley twist pillars, matched by quarter pillars at the back. The square and moulded base rests on four raised bun feet.
