About this model:

The Seiko 5T52 series is an analogue quartz traveller’s “world timer” with a city ring and a 24-hour world time display, plus an on-watch alarm. Seiko’s technical documentation shows the city hand being set with pushers and the world time being displayed independently of the main time, and it describes both regular and single-time alarm checks.
