Purchased a non runner Elgin grade 921. disassembled and figured out the mainspring has broken into 2 pieces. Obviously it won’t work. So I researched what mainspring I would need and I figured out that mainspring part #817 is what I needed. Ordered, installed wound up and it felt wayyyyy too...

I have been reading an old patent for research, and it said that the barrel in the system displayed had about a 30 hour power reserve and needed 4 turns of the arbor to wind. It did not, however, mention the size or the amount of teeth on the barrel (or any of the other gears), so I don't know...

I am doing some research and a lot of people are saying that a large barrel is less accurate than a single barrel and a twin barrel is more accurate than a large barrel. There are some things I can't figure out though. I can see why a large barrel makes the movement less accurate, because it...

I'm suffering with a power crisis and need help! I'm working on a vintage diver... it's a cheaper mechanical Sheffield and I actually got a couple of them on eBay in an attempt to rehab one with the extra pieces. It all looks great (washed, inspected, re-assembled) until I wind it up. For a...

Would anyone here be able to provide photos or illustrations of the different double barrel movement setups? I realize that in one setup, one barrel feeds power to the other, and delivers torque more evenly over time. While the other setup just serves to provide a longer power reserve. But can...

I recently bought some old elgin pocket watch movements off eBay. They are of varying sizes and all are early 1900's pocket watches. I've taken one apart and cleaned the parts in an ultrasonic cleaner. However, while I have it apart, I wanted to test the mainspring. It's currently in its barrel...

I know that some double barrel movements use the extra barrel primarily to even out variations in power that is provided. While most double barrel movements are to increase power reserve. My question is: do double barrel movements that have the extra barrel for the purpose of increasing power...

Basically 5 elements are needed. It's this simple:

is this doxa barrel interchangeable with other calibres? this is calibre AS 1147 i've found a calibre that resembles this one (the three jewel bridge is the same) but with the gears that help wind the barrel different . could it be a good match for the barrel of the AS 1147? thanks
