Welcome to my Top Wristwatches Boutique! A major evolution of YEMA's 1960s iconic model, the new Superman 500 GMT preserves its main professional diving features while providing a 3-time zone GMT function for all globetrotters. Equipped with our In-house Caliber YEMA3000 and for the first time water resistant to 500m, this enhanced Superman benefits from a modernized architecture and substantial technical improvements that position it as the ultimate French professional diver's watch. The bezel-lock, the Superman’s centerpiece which design was patented a long-time ago, and the crown tube have been redesigned to ensure a smoother operation and that the bezel-lock stays securely in place. The bezel and the crown have also been redesigned. New micro drilling in strategic areas of the case right under the bezel allows for optimized rotation of the bezel click spring and a more precise alignment of the bezel insert. The winding crown's architecture has been completely reviewed. The crown tube and the winding stem have been modified to provide a smoother operation of the various pull-out crown positions and rotating directions when adjusting the caliber functions. When winding and setting the time of the Superman, the improved crown provides a feeling of stability and quality. Beyond its GMT functions, the Superman model is above all intended for diving professionals, now benefiting from an enhanced water resistance of 500m and technical improvements allowing it to adjust the bezel on the water surface when unlocking the bezel in the unscrewed crown position. The 316L stainless steel case back thickness has been increased from 1.5mm to 2.2mm so as to achieve a 50 ATM water resistance. YEMA's historic crest, embossed with a hydraulic press, is now treated by various microblasting processes, which results in a more accurate and precise finishing. The markers, hands and bezel are treated with Super-LumiNova Grade A to ensure increased readability. The bezel’s luminescent marker at 12 o’clock and the luminescent arrow-shaped minute hand provide scuba divers with an accurate indication of dive times in poor visibility conditions at the greatest depths. The luminescent 24-hour scale on the bezel and the luminescent hands facilitate reading of the three time zones in all situations. My personal opinion, based on 30+ years of collecting experience: connoisseurs and watch lovers, don't miss the chance! Very stylish and extremely reliable watch, it's more than a piece of watch art and story, this is a profitable investment, too.
