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.

Spinnaker Dumas Automatic

The watch is noted for its comfortable wearability, attributed to a short lug-to-lug distance, and owners report positive experiences with the Seiko NH35 movement. Some owners mention a mineral crystal instead of sapphire, a bracelet with a learning curve, and a crown that feels slightly small. Overall, owners rate the Spinnaker Dumas Automatic highly for its aesthetic appeal and solid construction at a fair price.
