The first fully-enclosed clock known dates to 1665, the one pictured here was made by Edward East in London, dated 1685.

Now instantly recognisable as a longcase, or "grandfather" clock.

From now on the timekeeping of clocks improved by a huge amount using the longer pendulum and "anchor" escapement.

Around the same period, with a slightly larger dial and a wooden hood to keep the dust out of the clock movement.

From 1730 longcase clocks ceased being made in London, the clockmakers followed the demands of fashion, and made bracket, or shelf clocks.

Eventually most clocks went back to a plain or matted centre again.

One-handed clocks continued to be made in country areas for a long time, so one hand is not an absolute guarantee of an early clock, but is a good guide.

Village life was very conservative, and the people living in villages at this time still had no real need of to the minute time.

1700 to 1740 the size went to ten inches square, 1740 to 1770 the dial is likely to be eleven inches, and by 1770 the size went to twelve inches and stayed that size.

There are exceptions to these sizes of course, but they are a good general guide when taken with other features.

A "bird-cage" movement (it has vertical pillars and the plates are horizontal top and bottom) is often taken to be a sign of an early clock.
