EN SAVOIR PLUSNEW MODERNIZED DESIGN
For almost 2 years, we have imagined and worked on an evolution of the Superman model. Our desire was to bring to this mythical model of our collection, technical improvements and a modernized construction while preserving its iconic design.
NEW BEZEL ARCHITECTURE, BEZEL LOCK & CROWN
The bezel stopper, the centerpiece of the Superman, patented at the time by the brand, has been redesigned to ensure a better fit between the crown tube and the bezel stopper. The latter is therefore more stable.
To do this, we had to redesign all of the bezel and crown components. Additional bores at the bezel have been made allowing for optimized travel of the pawl spring and more precise alignment of the bezel insert.
The crown architecture has been completely reworked. The length of the tube between the crown and the bezel lock has been modified, giving it better notching and better stability. When winding and setting the time, in the unscrewed position, the crown provides a feeling of solidity and high quality.
SAPPHIRE GMT 24H BEZEL
3 TIME ZONES
Bi-directional 24-hour graduated bezel made of scratch-resistant sapphire crystal, offering a high-quality shiny appearance. Innovative treatment in highly qualitative Super-LumiNova Grade A. Designed for travelers, the GMT complication allows up to 3 different time zones to be read using the GMT hand and 24-click rotating bezel.
IMPROVED WATERPROOFING TO 500M
Beyond its GMT functions, the Superman model is above all intended for diving professionals, now benefiting from a water resistance of 500m and technical improvements allowing it to adjust the setting of the bezel, in the unscrewed crown position, on the surface of the water before immersion.
Main characteristic of a diver and in order to offer this new Superman with a water resistance of 50 bars or 500m, the bottom of the case goes from 1.5mm to 2.2mm thick. The historic YEMA coat of arms is stamped with a hydraulic press and is now treated by various microblasting processes for a better rendering in relief.
DAY / NIGHT FUNCTION
During the Antarctic summer period 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 sunshine, 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 nighttime hours.
FONCTION JOUR / NUIT
Pendant la période d’été antarctique le soleil est presque constamment dans le ciel, les journées s’allongent rapidement jusqu’à ce que le soleil ne se couche plus, un phénomène qui s’appelle le Soleil de Minuit.
Lors de cet ensoleillement perpétuel, la lunette GMT graduée 24h permet de distinguer le jour de la nuit. La lunette est divisée en deux moitiés chacune avec une couleur distincte, l’une correspond aux heures diurnes, l’autre aux heures nocturnes.
SUPER-LUMINOVA GRADE A
Switching from Super-LumiNova Grade Standard to Grade A to ensure increased readability and make it easier to read the three time zones in any situation. The GMT bezel with its sapphire insert combined with Super-LumiNova required a particular and innovative design in order to provide day/night visibility even in the dark.
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.
SUPER-LUMINOVA GRADE A
Passage de Super-LumiNova Grade Standard à Grade A pour assurer une lisibilité accrue. La lunette GMT avec son insert en saphir allié à du Super-LumiNova, a demandé une conception particulière et innovante afin d’offrir une visibilité jour/nuit même dans l’obscurité. Cette construction spécifique et minutieuse a notamment permis de dissocier réellement la lunette en 2 parties, comme en attestent les index de 6h et 18h.
Le repère luminescent sur la lunette graduée et l'aiguille luminescente en forme de flèche fournissent au plongeur une indication précise du temps de plongée en condition de mauvaise visibilité dans les plus grandes profondeurs. La graduation 24H luminescente sur la lunette et les aiguilles luminescentes, facilitent la lecture des trois fuseaux horaires en toute situation.
IN-HOUSE CALIBER GMT YEMA3000
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.

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."
