The second watch she inherited was a Patek Philippe pocket watch.

It's 23 jewels, PW/PS, open face. The dial has a seconds chapter at the 6 o'clock position and there is a second second chapter around the outside of the dial and two sweep second hands. All the hands except the 2nd hand look like they are made of gold. The dial is signed Spaulding & Co. Chicago.

The back of the watch is engraved with the initials AEB. Inside the top cover there is a 0.750 mark to show it's solid 18K gold. The couvette is engraved around the edge. At the top is:

Spaulding and Co Chicago

At the bottom:
Nov. 17th No. 90040 1903

The movement is marked:

Patek, Philippe & Cie.
Geneva
Swiss
Spaulding & Co.
Chicago

It also shows the serial number 90040 which my book says is 1895-1900.

This is the case back:

A closer view of the movement.

If I try to wind the pendant, the watch will run. The spring won't wind, but the movement runs.

Any info as to exactly what this would be called or any other info is appreciated.

Tim,
Very interesting split seconds chronograph. Perhaps the mainspring is already fully wound? Does the watch run on its own or will it only run when you turn the pendant?
RR

Only when turn the pendant. Your comment made me think and I went to see if I could see the winding mechanism. Unfortunately, it's hidden under the top plate. I don't see any way to let the mainspring down.

I've been told that the best way to have this fixed is to send it to Patek, Philippe. Has anyone ever sent a watch to them?

Tim,

WOW

The other watch from dad-in-law was a pretty pedestrian Columbus Watch Co. SN 90480 it's HC SW/LS NI GJS. I think it's a 15j, but I only count 13 so far. I'll post a picture in another place. There are no family engravings on this one, but it is in great shape according to the local guy I took it to.

After getting these three watches I've collected a few others but they are pretty much all American; Hamilton, Howard, Elgin, Hampden, and Illinois.

The two Swiss watches are pretty overwhelming with their complexity and value. Not watches I should be experimenting with!

Tim - those are absolutely gorgeous watches that your wife inherited! They are to be treasured, not just for their beauty and complexity, but because of the family history. Most definitely not your every day carry watch!
