From my Great Uncle Ray's Estate (former watchmaker).  This appears to be fully original based on case and case screw marks not evident.

It is lever set and was made in 1919.   That's pretty good for 105 years old.

This watch was not in his book of service records, so I have no history.  Although I would assume it had a new mainspring installed at some point based on the firm wind.  Based on the tray these watches came from, I am assuming it was on his list to do a COA (Cleaning, Oil and Adjust). As he would do that to every watch he acquired. I will note only under a MACRO lens you can see a thinner than hairline around the right of the 10.  It is unnoticeable without a loupe.

There are great folks on some of the Facebook groups who do this for as little as $50.  Just look around.  It's not necessary, but if you are as OCD as my late Great Uncle Ray, then it's worth it.

Will be packed extra sturdy to prevent shock from any drops or mishandling.

I have a strict no return policy in place, as a recent buyer switched out a balance and bridge on a VERY expensive watch and then claimed it arrived "not as described".  If there is a legitimate problem, please let me know.  Things do happen, and we will fix the issue.

The pictures and video are the final descriptor of the item.

Will ship UPS insured.  All the carriers have gotten crazy with their prices!!!  Movement will be double boxed and I try to get the item out the day or 2 after payment is received.  I double box and heavily secure.  I have no control over the awful raise in cost to ship and I personally pay for insurance, so we are both covered.

Any questions, please ask.

Thank you for looking!
