Gruen Watches can have a value from $600 to amounts as high as $35,000. The value depends on the model, condition and age of the watch.
Gruen watches, which were manufactured from 1904 through 1917, were among the most expensive watches in America. If a Gruen watch is in good condition, it can be very high in value today. One of Gruen's signature watches, the VeriThin pocket watch, can be valued at $1,250. The UltraThin pocket watch can range from $9,000 to $31,000, while the Ultra-VeriThin, the less expensive but similar version of the UltraThin, has a value of roughly $2,500.
