I'm getting a hour-glass.

Much better than a regular timer when you're doing the "Pomodoro" method and have to get something done. But I also have a nice lava-lamp, which is great when you're listening to music. And a record-player for vinyl CDs. And fidget toys for my ADHD and Autism (to stim while I'm doing something).

I'll be honest: I need eitiher:

Portability

Analog

If I can't carry it or if it's not mechanical, the i don't care.
