GRUEN Watch Company  

One of the most important and prestigious American watch manufacturers. Gruen watch company was a watch manufacturer founded in 1894 as "D. Gruen & Son" by a brilliant German horologists, Dietrich Gruen and his eldest son Frederick G. Gruen. Years later, the second son. George J., joined the firm and the name was changed to "D. Gruen & Sons". 

"Gruen obtained a patent for an improved safety pinion, and it is the date recognized by the Gruen Watch Company as the start of its business." Early Gruen watches included pocket watches and wristwatches for men and women.

Vintage watches are traditionally smaller than today's watches. Men’s watches typically measure between 29-36mm wide (some larger, some smaller) excluding the crown. In the listing details we typically try to do our best to list all pertinent dimensions of a watch. If you don't see it, or we failed to do so, please reach out to us. Women’s watches from the 1900s-1970s were also much smaller than today's offerings. Please also feel free to ask any questions you have pertaining to size. 

We prefer to shoot photographs outside when weather is permitting. However, when we shoot indoors, please be aware that we shoot our photographs inside of lightboxes that are lit with 360 LED bulbs. This indeed magnifies any flaws. Usually, they are much less obvious to the naked eye. Having said that, we never photoshop any of our photography, remove blemishes, etc. We adjust the lighting, when necessary, but what you see is what you are getting, and we take pride in that. 

The condition is pre-owned. 
The item may have some signs of cosmetic wear but is fully operational and functions as intended. 
Please review the photos and feel free to ask any questions you may have.  

It will be carefully packed.
