Glycine Airman SST GMT GL0309

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.

Zelos Hammerhead 2 1000m NH35

Owners and reviewers praise the Hammerhead 2 1000m NH35 for its value and wearability: one owner who has worn theirs daily for almost four years calls it heavy but loved, and another likes the case angles and the 1000m water resistance with a helium escape valve. Reviewers single out the well-machined case and the Seiko NH35 movement, which one found kept good time, and another calls the movement a solid workhorse for the price. The main caveats are thickness, around 17mm including the domed crystal, which one owner found off-putting, plus double-domed sapphire reflections in full sunlight, and one reviewer found the indices' lume noticeably weaker than the bezel, hands and crown, with accuracy around 8-10 seconds per day and about 40 hours of power reserve on the modest side. Overall, owners and reviewers rate it well for the money, with its build quality and wearability doing most of the work.
