“Cheapest” mechanical watch that still gets wrist time?

Hi OF. As my watch collection grows more collectible and more vintage, I find myself having more limited wrist time. Just wondering what is your most "cheapest" mechanical/automatic watch that still gets some valuable wrist time? And I'm not talking about some beloved G-Shocks, Swatch, Timex, or even Apple.

Here is my Oris Artelier Complication that I found for a cool $400.
