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 widely praise the IWC Schaffhausen IWC Aquatimer Chronograph as an underappreciated, overbuilt tool watch prioritizing engineering and reliability, with its Valjoux-derived movement offering durability and its chronograph pushers providing mechanical feedback. Reviewers and owners consistently flag its impeccable finishing, captivating appearance, dial depth, and excellent lume, with one owner noting its comfortable wearability despite its size and thickness. Some owners find the chronograph variant chunky at 17mm, and the welded lugs limit strap options to OEM choices or require specific modifications for third-party straps. One owner notes the watch's 120m water resistance, attributing the reduction from the non-chrono version to non-screw-down pushers. Overall, owners rate the IWC Schaffhausen IWC Aquatimer Chronograph highly for its robust build quality and functional design at the price.
