D. J. Gale's Astronomical Wall Calendar Clock. Balance wheel escapement. Spring powered movement.

This is a Gale Astronomical Calendar gallery clock. It was offered in two dial sizes. The smaller version had a dial diameter of 12 inches. This larger example has a dial that measures 24 inches across. In addition, two variations of case forms were offered. The simpler cases were veneered in richly grained rosewood. The solid wood cases were offered in oak, black walnut and mahogany. All of the cases were fitted with coil spring powered movements One had a choice of a pendulum escapement or a balance wheel format.

This is the larger rosewood veneered example. The case measures approximately 30.5 inches in diameter and is 5 inches deep. The rosewood veneer is in outstanding condition. The surface has been wonderfully finished so that the natural grain patterns are vibrant. The wooden bezel is fitted with glass in order to protect the dial. This is hinged on the right.

This dial is painted on zinc and is in very good condition. This example is referred to as the 1871 patent version. It is formatted into five separate displays. The upper dial displays the time with a minute and an hour hand. The lower dial indicates the month of the year. There is also a table that calculates the time of sunrise and sunset during that month. The small hand between DEC / JAN indicates the number of years since the last leap year. The dial on the right will indicate the phases of the moon or the day of the lunar calendar month. The dial on the left indicates the day of the week. The last dial is found around the outside edge or the perimeter of the dial. This displays the calendar date of the current month. All of this is incorporated in a perpetual design which will account for the variation in the number of days in each month and also leap year. It is interesting to note that the back of this dial is also painted to match the front.

Two coil springs wound through the dial power this clock mechanism. It is constructed in brass and is designed to run eight days on a full wind. This movement does not strike. This example is designed with a balance wheel escapement. It does not have a pendulum.

This very impressive clock was made circa 1875.
