Note that the most you can spend on a clock is still a decimal point less than you can spend on a watch. My favorite - because it's like 9 feet tall and has a 3-second pendulum - is "only" like $200k.
Every now and then I go "It'd be fun to build an Uhrenbausatz M3" and then I go "bitch you've spent like $20k on a CNC machine so you never have to rely on anyone else's clocks ever again. Also you own like five books on making clocks." So yeah I guess my easy button is "spend entirely too much money on a clock kit" because 99.9% of the mechanical clocks out there have a Hermle movement and Hermle is garbage.
I own like $5k worth of gear hobs I should probably freeball like a desktop Riefler escapement or some shit
