Yema Superman 500 GMT 2023

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 GMT function for all globetrotters. For the first time water resistant to 500m, this enhanced Superman benefits from a modernized architecture and substantial technical improvements. 

Equipped with our In-house GMT Caliber YEMA3000, the Superman 500 GMT is available in three different models starting from February, 27th.

While preserving its iconic design, this enhanced Superman benefits from a modernized architecture and substantial technical improvements As the Franco-Swiss Jura Arc is increasingly integrated,.YEMA works now with new local suppliers for a more responsible and better quality production. 

The bezel clamp has been redesigned to ensure better stability with the crown tube. 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. 

With a new joint layout, it will now be possible to adjust the setting of the bezel and its bezel lock on the surface of the water. The Superman benefits from a 3 bar seal in the unscrewed crown position representing a major improvement.

While maintaining its thickness of 2.6 mm, the double dome sapphire crystal has also undergone a change to make it more resistant while retaining the original DNA of the Superman. The height of the glass has been reduced by 0.3 mm while widening by 0.6 mm on its outside diameter.

An Improved Superluminova Construction

The markers, hands and bezel are treated with Super-LumiNova Grade A to ensure increased readability. The GMT bezel with its sapphire insert combined with Super-LumiNova, required a special and innovative design to offer day/night visibility even in the dark. This specific and meticulous construction made it possible to really dissociate the bezel in 2 parts, as can be seen by the indexes at 6 hour and 18 hour.

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 facilitates reading of the three time zones in all situations.

Pierre Hedan - A new Yema ambassador

Pierre HEDAN, a 25-year-old French explorer and YEMA’s ambassador, will wear a Superman 500 GMT during his big solo expedition to the South Pole later this year. An engineer by profession, Pierre quickly developed a passion for alpinism thanks to his Savoyard grandparents. At the dawn of his 20th birthday, he undertook the ascent of Mont-Blanc, then that of Kilimanjaro.

Pierre now dreams of following in the footsteps of Roald Amundsen, the first man to reach the South Pole in 1911. His upcoming expedition project is named POLHEIM EXPEDITION, during which he aims to reach the South Pole from the coast of Antarctica by foot with no support team, covering 650 kilometers over more than 40 days under extreme conditions. Pierre will notably be equipped with the new Superman 500 GMT as a main time instrument and secondary navigation method.
