c.1850 Miniature Japanese Wood Pillar Clock. A good quality Edo period Japanese miniature pillar timepiece with a drawer to hold the original winding key and original glazed removable hood. The one-day, weight-driven brass movement has an engraved skeletonized front plate, a verge escapement regulated by a shaped brass balance wheel and has finely turned decorative corner and movement posts, wheelwork and arbors. The scale, secured by hook at the bottom and screw at the top, has thirteen adjustable silvered engraved temporal 'hours'. The lead weight carries the shaped brass hand that points to the time as it descends through the day. The vast majority of pillar clocks are over sixteen inches long. It is exceedingly rare to find such a wonderfully preserved example in a diminutive size.
