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.
The Tissot Seastar 2000 Professional 44mm is widely praised for its exceptional value, offering impressive specifications like 600m water resistance and an 80-hour power reserve from its automatic movement. Owners and reviewers highlight its attractive dial, often featuring a fading blue color with etched waves and a color-matched date window, along with Tissot's generally appealing designs and good build quality. The engraved ceramic bezel numbers are noted as a significant improvement. However, the 44mm case size is a point of contention, with some finding it substantial and feeling larger due to its lug-to-lug measurement, while others appreciate its short lugs which make it wear less bulky. One owner reported a bezel click action failure after 14 days. Overall, owners and reviewers rate the Tissot Seastar 2000 Professional 44mm highly for its robust build and technology at an exceptional price point.
