A popular choice for pilots the Breitling Navitimer World GMT a lot of watch i after to say for the money, never understood how to use the slide rule thou that comes with the package. The Navitimer comes in a few variants which is powered by self winding Breitling in house movement, and all come with chronograph function and a date window also a red hand which displays another time in a different part of the globe hence called Gmt, always found some Breitlings have a lot going on the dial for my liking but a good size at 46MM in stainless steel.
The caseback is engraved with time zones of the major cities around the world but all round nice and comfortable piece, but decided to let it go a while back.
