It's been a BUSY NEW YEAR!


NEW tools for dating your Gruen watch!

Serial numbers for cases made by Gruen, Keystone, Star have just been released. You'll find them on the Serial Numbers page.

More Gruen Annual reports. A generous reader has located and provided to me the "missing years" and in the process almost doubled the number of pages to 342 pages!

And, a new "series".... 

"Fred's Big Adventure!"

In this series of PDF posts contains pages from Fred's hand-written diary chronicling the train trip he took with George Gruen in Aug of 1934 (I think). The trip was from Chicago to Yellowstone and was over a week. There are 200 small hand-written pages. The handwriting is difficult to read, so I'm having this document transcribed.

We will all learn together what kind of writer Fred Gruen was as the pages are being transcribed and released a few at a time.

Keep checking back as more pages are added every day or two! 

More free stuff! An early version of the Gruen Horological Text

I'm making available another newly discovered Gruen document. For the price of $0.00 you can download or read online the Gruen Watchmaking Institute's course materials. You'll find the 88 page document on the page titled FREE Watchmaking Course.  Enjoy and happy watchmaking!

A new lower cost, soft cover version of The Gruen Watch Catalog is now available.  



A plea to eBay sellers....

You can help Gruen research GREATLY with your ebay Gruen watch listing.  PLEASE consider taking clear pictures of the case interior & movement and embedding them into the listing itself.  Also, if you can include the serial numbers for the movement and case it will be of GREAT USE to Gruen researchers trying to do things like, oh, decode the serial numbers.  In fact, the recent publication of serial numbers for 4 case manufacturers couldn't have been completed without the help of ebay listings. 

Yes, these numbers sometimes don't mean anything, right now, but they most certainly will in the future!  These sequences will be decoded so that more accurate dating of Gruen watches can be completed.  Thank you to all the wonderful ebay sellers that have been providing this information in their listings! 

Remember to check your serial numbers against the movement AND case serial number databases!  You may be able to quite accurately pinpoint when your specific watch was made!  

New discoveries are published every few months (if not every few weeks) so keep checking back!
