Is the Apple Watch actually useful if you’re constantly switching time zones?

Student founder here studying at Tetr college, we shift to a different country every semester, and my schedule is becoming genuinely stupid 😭

Classes in one timezone, Client calls in another, Sleep schedule in absolutely none. Started wondering if the Apple Watch is actually useful for this kind of lifestyle or if it’s mostly a fitness/status thing.

Does anyone here actually use one for productivity/travel chaos?  And if yes, which model is worth it without spending Ultra-level money?
