As some of you may know, I recently purchased two gold-filled pocketwatches from the turn of the last century. One of them is a 17-jewel Waltham Riverside. The other is supposedly a 15-jewel IWC Schaffhausen.
My question to you folks is...is it really what it is? I only really have the word of the fellow who sold the watch to me, who said that it was a 15j, 16s IWC from 1890.
I can only give you the following information:
The case is gold-filled. The caseback and the interior dustcover have the serial number 169,715 on them.
The movement has the serial number 143,331 on it.
The dustcover has an engraving on it that reads:
"WARRANTED GOLD FILLED CASES TO LAST 20 YEARS / SWISS MADE".
That's absolutely all I can tell you about the watch. There is also a MINISCULE mark on the watch movement, below the winding-click. It's so small that even with TWO magnifying glasses, I can't read the damn thing. That's all I have to go on.
The watch runs and sets perfectly, although the bow is very loose. I shall take it to the watchmaker in due time, to have it serviced.
Are there any IWC serial-number resources that I can read, or which you folks could look up, that would tell me if this watch is an actual IWC? I tried searching, but the one reference that I found looked less than reliable, although if it was taken as truth, then it seemed to indicate that my watch was made between about 1885-1895.
I pulled out my absolute most powerful glass that I have to have a look at that stupid mark on the movement. It's an oval with a crown inside it, with SOMETHING written underneath the crown, which I doubt even an ant with a microscope could make out. Here is the watch:
IWC on the LEFT (Riverside on the right).
In this last photograph, you can probably *just* see the oval mark on the left. It's above the winding-click and below the movement-screw next to the case-hinge.
