... two-timezone watches permitting independent adjustments of the two dials. Rainer Brand had a very attractive one, the Panama, but I think it is discontinued. And of course there are several watches featuring two independent movements in one case. Glycine is over the top with its Airman 7, with three independent movements in one oversized case. However, in its most recent version, Glycine irrationally truncated the watch's useability by deleting the minute hands on the two subdials, making it needlessly complicated to compose the the other time zone display, and impossible to set a half hour difference.
