Actually, the pic is a little misleading. The hole is absolutely round. I think I can make out a faint wear mark which indicates the orientation of the washer. It looks as though it goes convex side against the plate with the concave side against the bottom of the wheel.
I found the place where the 'canoe washer' came from thanks to your explanation.
Looking very closely, I can see a little residue mark that matches a small portion of the curve of the washer on the bottom of the canon wheel.
Will it matter which side up this washer is installed?
I am trying to clean a clock that my family has had for a long time. I think it is about 100 years old. There are no markings anywhere on it aside from on the dial where it says,

Thank you everyone for your help. I ordered a new floating balance wheel wire and replaced it. I cleaned the movement as best I could without doing a complete teardown - I was too timid for a teardown! After doing that, I found that the balance wheel was rotating about 300 degrees and I was...
The clock is running about 15 seconds fast per day even though it is set to its slowest setting. After having cleaned the balance wheel mechanism it slowed considerably, but still not enough to be fully within the limits of the regulating setting. I guessI'll probably have to...
My God! This is complicated stuff! I seem to have unearthed a world that I never before knew existed! Fascinating!
At the risk of appearing like the complete village idiot, could I not simply add a little weight to the balance wheel to make it rotate more slowly.
I was up all last night and...
Thank you for your replies. I will try a strip-down cleaning. I have noticed that the balance wheel is not exactly perpendicular to its 'axle' (forgive me for likely not using the correct term there), but it does seem to rotate freely. It rotates about 100 degrees each direction, which from what...
I am new to this list as my wife and I have recently inherited my father-in-laws clock repair hobby/business tools and clock bits and pieces. This looks like a tremendously helpful group for what I see as a fascinating hobby for me.
I have been working on a Hermle mantel clock for a...
