This is a rare Meister Anker GMT World Time with rotating inner Bezel.
It dates from the early 1970's and is in really good condition.  

The dial is silver and reflects the light off the surface making it gleam at most angles.  The green batons are capped with a sliver square to make reading the dial easy.  

The external bezel rotates in both directions and allows you to set the time anywhere in the World.  The external bezel is in good condition.  The internal bezel is in perfect condition and also rotates in both directions.  USing the internal bezel allows Divers to set oxygen time and yatch masters to time races.  

A very versatile watch that runs well.
