Nauticalia

On arrival in foreign lands - especially if it's after several days or weeks at sea - it can be difficult to work out the local time, and/or time back home. With this patented, award-winning bezel, it's very simple: just rotate the bezel until the city (from a choice of 23) in your desired time zone aligns with the 12 - and the hour hand will move round to the correct place, and afterwards continues to go round as normal (minute hand is unaffected by bezel rotation). It's much quicker than re-setting a normal clock, and you can't get it wrong.

Diameter 2.4". Battery included.
