How a co-axial escapement works
Consider this a public service announcement. :-) I was trying to see or read how a co-axial escapement works, like at the mechanical level. After watching many videos that only confused me more and reading many articles that seem to gloss over the most important bits, I finally found this low-res video. It has a large Omega demonstration model which clearly -- and SLOWLY -- shows the movement of the escapement while someone explains what's happening.
The confusion, for me at least, was that there are 3 jewels on the pallet fork and 1 on the balance wheel. Two of those interact with one of the escapement wheels and 2 interact with the other, co-axial wheel. Seeing how they interact at a slow speed really brought it home for me and made it easier to understand.
You're welcome! ;-)
Into Bremont, Tudor, Vertex, Christopher Ward, and most other watches, sadly. Have way too many divers.
