An early 20th century type A1 astronomical regulator by Sigmund Riefler:

Sigmund Riefler, Munich, an early 20th century type A1 astronomical regulator, the art deco influenced mahogany case with molded top and bottom, cylindrical corners, and mahogany dial mask with two ebony banded inlaid squares, hinged to a maple frame and panel back board with nickel plated adjustable beat scale and cast iron, rear mounted movement mounting and leveling bracket, silvered roman and arabic numeral astronomical dial with polished steel hands, signed “S. Riefler Munchen”, jeweled type A movement with spring impulse escapement, electric remontoire, and knife edge suspension resting on polished agate pads, type J seconds beating invar pendulum with barometric compensation and tray for fine timing weights, serial #1355, together with it’s boxed control panel with rheostat and relay

Condition

case front sags a bit, some joints with separation, case would benefit from disassembly and regluing, left side glass with crack at top, case back with splits at top and bottom, dial and hands good, movement good, plates darkened, running, electric remontoire not tested, pendulum good. The absence of a serial number and year is a bit of a puzzle. The dial is lined for the engraving of this information, but the work was not done. The serial number on the pendulum would suggest a date between 1910 – 20. The barometric compensation unit is a very good reproduction of the original, made in Germany between 2000 – 2010, circa 1915, ACCESSORIES: Original Coiled Wire & Extra Screws, Control Panel, Pendulum, Beat Scale, Dial & Movement, Dimensions: 59.75in x 17.25in x 8.5in
