CITIZEN's professional sports watch brand “PROMASTER” presents 3 new models from all its categories for professionals; MARINE, LAND, and SKY. Since its launch in 1989, PROMASTERhas been a firm favourite with professionals who challenge their limits, withstanding the toughest ofconditions, achieving top endurance, and o-ering numerous superior functions for di¬fferent fields.
For the climbing, diving, and aviation enthusiasts across the world, CITIZEN has detailed out the specificconditions and introduced 3 categories –MARINE, LAND, and SKY– to off¬er the ideal functions and specs for each scene.
The challenge for the professionals is not just pushing their physical but also their mental boundaries.This is why PROMASTER is equipped with high functionality, durability and safety with designs thatexude confidence and class to drive them to go beyond their ‘imagination.’
World's first light-powered watch
for 1,000m saturation diving
The Eco-Drive Professional Diver 1000m is ISO compliant diver's watch that can performseven in saturation diving environment. The escape valve set at 10 o'clock on the case sidereleases the helium gas that enters the watch during saturation diving to prevent anydamage or rupture upon the movement.
There is no need for regular battery replacement thanks to the Eco-Drive technology. The PowerReserve Indicator tells divers the remaining battery charge so that they can enjoy diving worry free.
To achieve an even higher practical functionality, CITIZEN conducted validation andvilification testing with cooperation of JAMSTEC*7 (Japan Agency for Marine-Earth Scienceand Technology), the ocean research authority in Japan, to conduct a leak test and examinethe eff¬ects of high water pressure to check waterproof performance in a high-pressureenvironment as well the dial visibility, and luminous features in deep waters.
Unidirectional bezel /Bezel-locking mechanism
We made the bezel of the PROMASTERunidirectional in line with the ISO standard fordiving watches. This improves safety byeliminating the danger of a diver accidentallyturning the bezel the wrong way during a dive.The Eco-Drive Professional Diver 1000m model isequipped with a bezel-locking mechanism.
Luminous hands and dial for high visibility
PROMASTER's photo-luminescent markings absorb lightfast and stay bright for a long time. We made sure that agenerous proportion of the hands is coated in luminousmaterial and tested a range of colours before selecting themost visible ones. The luminous materials used for thismodel has more than twice the afterglow brightness than aconventional material even after 5 hours. We use thematerial which does not contain any radioactive material.
When the bezel lock is set to FREE,t h e o r a n g e w a r n i n g c o l o u r i sappeared to warn the user. Thecrown also has a same mechanism,revealing an orange colour betweenthe case and the crown to tell theo w n e r w h e n t h e c r o w n i s n o tcorrectly pushed into a lock mode.
Culmination of the expert technologies that achieve high durability and water resistance function
A diver's watch that performs with 1,000m saturation diving must not only pass the water resistance test, but also a test to keep performing for 15 daysin a pressurized chamber that contains helium and oxygen or even 100% helium gas and then revert back to atmospheric pressure within 3 minutesafter high-speed decompression. The pressure is an unimaginable 125 barometer which demands high durability and water resistance function. This isa world's first as a light powered watch.
CITZEN's proprietary titanium material, Super Titanium™*8 has various surface-hardening technology which is expertly used to off¬er the functionsrequired for each of the parts to collectively achieve a robust surface finish. In order for the adjoining sections of the parts to also withstand the waterpressure at 1,000 metres depth, we applied one of the hardening technology, “Duratect*9 MRK” to the case when parts like the crown tube and theescape valve tube were already in place, we bonded the individual components to the case at the atomic level to achieve a higher level of adhesion.(The technical name for the process is “solid phase di¬ffusion bonding.”) The result was not just a tougher case surface, but durability capable ofwithstanding 1,000 metres of water pressure.
Inspired from the turban shell structure
The Eco-Drive Professional Diver 1000m takes its design inspiration from theshape and structure of a turban shell. The durability and power of this shellcase design was tested to the limits in successfully producing a professionalgrade light powered dive watch with a water tight fit to 1000 metres.
The hardness of the shell comes from its brick structure which was reflected tothe case side. The spiral structure of a turban shell gives the directional design tothe bezel which is not simply an iconic design but functions as a way to intuitivelyinform the direction of the bezel.

A light-powered watch with altimeter
that can measure up to 10,000m
Introducing a new design from “Eco-Drive ALTICHRON,” equipped with the CITIZENadvanced technologies including altimeter that can measure up to 10,000 metres.The Eco-Drive ALTICHRON can measure far beyond any mountains aroundthe world from -300 metres (under sea level) to 10,000 metres.With allthe informationisplayed in analogue rather than digital format, there isno need to switch away from the all-important time display to checkaltitude or orientation. It is designed for users to operate its functionsintuitively by coding the hands colours that show time and otherinformation and making the dial layout simple.
This new “Eco-Drive ALTICHRON” with basic colour of black is designedas a chic watch that is perfect not only for outdoor but also for businessscenes. The outdoor-style watch with the all-new design that looks greatfor any scene is the perfect addition to our proud collection.
