If I'm posting this in the wrong thread, of course let me know.
I'm a high school student who is about to start their senior project, a project that is supposed to be something with a big learning stretch, and as such I've decided to CNC a body for a watch. I've already designed a body around a very cheap Chinese movement (the ST6D3KS) but am unhappy with the end thickness (about 10mm). This leads me to want the best opinion i can get on what movement I should buy. I'm looking for the thinnest mechanical automatic movement with a date @ 3. I would like to keep the cost under $70 USD if possible. All help is appreciated.
