I collect mostly vintage watches, and as such have a few GPs as well. Still very new ti this brand, but I like the style and quality very much and plan to acquire few more pieces. As of right now, I only have this one, Gyromatic 39 with diamond dial, Original (1945 or so) SS Sea Hawk w/ Breguet nume
Bought this one few years ago and love it! Only found 4 other ones on the web. There was a question related to model 5420 vs 5080 as they are almost identical two tone watches. I'm not sure I can contribute much, but the movement seems to be slightly differently marked - 5420 has '2 adjustments' imp
