The "Aerospace GMT" was Zodiac's evolution of the popular "Seawolf" model. This is a tough watch from the 1960's. These were apparently sold at PX's abroad and thus may have been used by those in the military. It would have been the perfect watch for a guy in the Navy or Airforce because it was made to be used by active guys that traveled across time zones and were in need of a reliable and carefree watch that looked cool and performed flawlessly. Some guys brought them home and used them for more casual travel demands! The handsome case is stainless steel and measures 35mm in diameter by 43mm in length. The date window appears at the three o'clock position and is a nice contrast to this original black dial and the red GMT hand. The 17 jewel movement is a wonderfully engineered, full rotor automatic, that is perfect for everyday use. The outer bezel rotates so that it can be adjusted for elapsed time or for interpolation of 24hour Greenwich Mean Time. The watch is signed four times: on the dial, the crown, the case and the movement so there is no mistaking who the maker was. The Swiss were proud of their accomplishments and this fine timepiece shows us why! So if you are an "Easy Rider" this may be the watch for you! Remember all of our timepieces come with our famous one year warranty for parts and labor so that you may buy with confidence.
