Keeping the Japanese theme - Citizen Tsuyosa, Seiko Speedtimer Solar or Seiko 5 Sports GMT. Probably Tsuyosa as something a bit more ‘special’ rather than ‘tool watch’.

I’ll give you the Casio Oceanus OCW-T200S-7AJF. I own one, and it’s one of my most worn watches.

The Oceanus line is Casio’s premium watches line and JDM-only (Japanese Domestic Market - the watch is imported from Japan). Official Casio product page (Japanese-language only). It’s a solar-charged quartz watch (powered by light), and has atomic clock radio time signal sync, which means it’s always 100% accurate.

Build quality and finishing are superb. It’s a set-and-forget watch that looks great and is very versatile.
