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.

NEW IMPROVED DESIGN

For almost 2 years, we have worked on a substantial evolution of the Superman model, by bringing technical improvements and a modernized architecture to this legendary YEMA model, while preserving its iconic design.

CROWN, BEZEL & BEZEL-LOCK NEW ARCHITECTURE

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.

TRACK THREE TIME ZONES

Bi-directional 24-hour graduated bezel with aluminium insert, offering a high-quality neo-vintage look. Designed for travelers, the GMT complication makes it possible to read up to 3 different time zones thanks to the GMT hand and the rotating (24 clicks) bezel.

PROFESSIONAL DIVING WATCH 500M

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.

DAY / NIGHT REFERENCE

During the Antarctic summer the sun is almost constantly in the sky, the days lengthen rapidly until the sun no longer sets, a phenomenon called the Midnight Sun.

During this perpetual day time, the 24-hour graduated GMT bezel makes it possible to distinguish day from night. The bezel is divided into two halves each with a distinct color, one corresponds to the daytime hours, the other to the night-time hours.

SUPER-LUMINOVA GRADE A

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.

MORE RESISTANT DOUBLE-DOMED SAPPHIRE CRYSTAL

The new double-domed sapphire crystal offers better readability, increased resistance, and a resolute vintage look.

The crystal has been reduced by 0.3mm on its height and widened by 0.6mm on its outside diameter so as to provide better seating in the case while preserving its 2.6mm in thickness and the beautiful magnifying effect when looking through it from an angle.

YEMA3000 GMT IN-HOUSE CALIBER

The GMT In-house Caliber YEMA3000 is powered by optimized components yielding slightly better performance than generic Standard Grade calibers (ETA, Sellita, Miyota), offering a Daily Rate of +/- 10 s/d and a 42h power reserve.

NAVIGATION INSTRUMENT

Primarily a time-measuring instrument for professionals and explorers called upon to travel the world, the Superman 500 GMT can also prove useful as a backup for navigational instruments.
To locate the cardinal points in the southern hemisphere, simply point the 12 o'clock index on the watch dial towards the sun, the north/south line is halfway between the 12 o'clock index and the hour hand.

DIVER STEEL BRACELET

The 316 L Stainless Steel bracelet with secure lock comes with a divers extension so you can adjust it easily and quickly over a diving suit.

RUBBER FKM VITON® BAND

Our new RUBBER FKM VITON® BAND has been engineered for intensive use in all extreme conditions thanks to its light, flexible and highly resistant VITON® material which also repels dust. The elegant 316L Stainless Steel deployment buckle adds style and comfort.

LOCAL PRODUCTION

During the last two years, YEMA has made substantial investments aimed at insourcing a good part of its production, constantly improving the quality of the manufacturing processes as well as developing a future range of French Manufacture calibers.

This significant development has required substantial R&D, new equipment and the expansion and modernization of our workshops and production lines. YEMA’s Manufacture Calibers benefit from improved precision and performance and will soon equip premium YEMA timepieces.

IN THE PRESS

PIERRE HEDAN

Explorer

"Together, let's start this crazy adventure. For many this may seem impossible, not within their reach but makes people dream. We must be disruptive in our thoughts, abandon our old convictions, get out of our comfort zone to demonstrate that nothing is impossible if we give ourselves the means. Let's collaborate with local partners to carry out this adventure. Let's value teamwork and collective success so that everyone can derive personal growth from it. Let's all be winners through this project that is the Polheim Expedition. If we want a future with a more sustainable world, we need to dream and dare to change the codes."
