The Glycine Men's Airman SST GMT 43mm Automatic Watch GL0312 is praised as one of the best values for a Swiss automatic GMT watch. Owners note its 1970s reissue design, referencing the brand's hometown of Bienne, Switzerland, and the dial's two black shades representing AM and PM. This model is recognized as an early purpose-built dual-time zone watch. Overall, owners rate the Glycine Men's Airman SST GMT 43mm Automatic Watch GL0312 highly for its value and historical design cues.
Owners praise the Spinnaker Challenger Automatic's comfortable 42mm DLC-coated case and satisfying bezel action. Reviewers note the fun, playful design featuring Popeye as the hour and minute hands. One owner flags the blue lume as weaker than green, and another finds the thick rubber strap difficult to manage. The ultra-domed sapphire crystal is cited as making photography challenging. On balance, owners and reviewers appreciate the Spinnaker Challenger Automatic for its playful design and solid build at its price point.
