Certina DS Super PH500MvsGlycine Airman SST GMT GL0309

Owners widely praise the Certina DS Super PH500M for its retro dive watch aesthetic, good legibility, and value, with many highlighting its striking orange dial and secure bezel lock. The Powermatic 80.611 movement is reported as consistent and accurate, with one owner noting +2/+3 seconds per day performance. The watch is considered tough and offers good specifications for its price. However, some find the 43mm case and 15mm thickness substantial, potentially wearing large on smaller wrists, and one reviewer notes the crystal retaining ring can be a scratch magnet. Overall, owners and reviewers rate the Certina DS Super PH500M highly for its vintage-inspired design and excellent value proposition.

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.
