The Glycine Men's Airman SST GMT 43mm Automatic Watch GL0309 is widely praised as an excellent value for a Swiss automatic GMT watch. Owners highlight its design, referencing the brand's hometown of Bienne, Switzerland, and its cool re-release from the 1970s. Its historical significance as an early dual time zone watch, predating the Rolex GMT Master and popular with Vietnam veterans and early astronauts, is also noted. One airline pilot considers the Glycine Airman SST GMT 43mm their daily wear and the best pilot watch ever made. The dial's two black shades represent AM and PM, with the hour hand at 6 o'clock signifying noon. Overall, owners rate the Glycine Men's Airman SST GMT 43mm Automatic Watch GL0309 highly for its historical significance and exceptional value as a pilot's watch.
Owners widely praise the Spinnaker Piccard for its comfortable wear, excellent readability, and bold, vintage-inspired design. However, some consider it a specialty novelty watch, describing the 45mm case as huge and heavy with a large crystal that hinders legibility, making it an acquired taste. On balance, owners appreciate the Spinnaker Piccard for its distinctive aesthetic and comfortable wear, though its size and legibility are polarizing points.
