Description
Blue box in the shape of an observatory. With text Gruen the precision factory, measurement marking and a gruen crest. Underneath Gruen Time Hill, cincinnati. Made in USA. Blue velvet insert with watch holder.

The design was inspired by the old observatory shown in the 1929 guild book (probably neuchatel). The exact length of a second was determined by the motion of the earth around the sun. The precise optics in observatories allowed a precision measurement for time.

Period : 1948 -1950
Watch type : veri-thin
Size : tbd
Inventor : unknown
Patents : unknown (patents pending)

Box maker : B. C. N. Design Products, Inc. of Middle Village, NY (doing business also under the name “Braun-Crystal Mfg. Co)
