This bumps up my desire to build my own mechanical watch using one of the kits here: https://rotatewatches.com (something I've had bookmarked for a while as a possible rainy day project)
Often a seller will be a small time watch maker and their components will all fit together, a good way to save on shipping.
Result: it's become my favorite watch, I wear it every day.
Next project was to use a bunch of cheap clone parts and a 3d printed dial, still working on that one :)
