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.
The Yema Superman Tourbillon CMM.31 Limited Edition is a titanium dive watch praised for its manufacture tourbillon and remarkable price point around €12,000. Owners describe it as an "incredible piece" and a "crazy watch" with impressive specifications, appreciating the "unnecessary" complication. While the 43mm case size is noted as large, its 13.8mm thickness and titanium construction contribute to comfort, though the bracelet clasp's extension system is considered somewhat crude. On balance, owners and reviewers rate the Yema Superman Tourbillon CMM.31 Limited Edition highly for offering a tourbillon complication at a compelling price point, despite some reservations about case size and bracelet finishing.
