Hello. I'm Keri and I mostly keep to the Russian Watch section of Watchuseek.
My location is CHICAGO (ЧИКАГО).
My latest project was a good cleaning, oiling and repair of Great-Grandfather Anderson's 1890 Dueber 18s (Hampden-Dueber) pocket watch in a Hunting-style case.
The repairs appear successful as the watch now keeps excellent time but I do have some questions to put to the experienced.
Here's the watch in a nutshell: He was likely given the watch as a wedding present in 1895 (having emigrated from Sweden in '87). He spent nearly 50 working in a steel foundry until he died in 1943. The watch was put away and passed from daughter to daughter to daughter (me, last year).
The watch was basically untouched for 67 years, being in bank vaults.
Here's the condition I found it in:
Engraving worn down.
Dirty. 50 years in a steel foundry kind of dirty.
Setting lever dangles when pressed in. (pops out OK)
After a great deal of study and some practice, I set about a careful dissection.
The setting lever "IN" spring broken in half, rub marks from continued use in broken condition.
The second hand was touching the dial, having left a circular rub mark.
The dial pins were bent, resulting in the dial being off-center to the movement.
Gross over-oiling, dried (70+ years old) oil residue everywhere Especially all over the winding train.
Dirt, dirt, more dirt and even MORE DIRT everywhere. A huge gob jammed in a gear very tightly.
Other than the broken spring, all parts intact.
So I made a new setting lever spring and it works fine.
I cleaned the movement and oiled it (probably over-oiled, because I'm an amateur) with Moebius 8200, 9020 and a bit of 9010.
I obtained a crystal and fit it to the bezel.
All parts (including the case and chain, but not the dial) saw plenty of Naptha, cleaner sprays and my ultrasonic jewelry cleaner.
I did not disassemble the mainspring from the barrel. The truly ancient grease still appears fluid, and the spring should probably be replaced.
So here's my questions:
1- The watch has jewels for the Balance Wheel and ONLY the top plate. I count 6 total. The bottom plate has no jewels. Was this a common upgrade? I'm assuming the watch had no jewels in 1890.
2- The watch case appears to be made by the The Newport Watch Case Factory (see picture). Do you think that this is the case from 1893-95 or was it replaced at a later date?
3- As the watch is easily stopped by movement, I'm assuming I over-oiled the balance wheel or should have left the pallet fork pivot dry. (1 jewel, 1 steel) In retrospect, I should have gotten the special pallet stone oil. (I used 9010) Any ideas? Also what would work well on the balance wheel pin / fork area?
Any suggestions, comments or questions are welcome.
Thanks in advance.
