AEROPOROS Black / Steel

IROAS AEROPOROS - the 1st collection of IROAS watches. AEROPOROS which means airman or aviator is styled after vintage pilot's watch and inspired by aviation dials. Designed with functionality and utility in mind, white indexes are clearly marked over a black dial to ease the reading of time. Enlarged 4 and 8 indexes adds some flair, which also serves as an extra indicator of 20 minutes interval (Index 4, 8 and 12 are all 20 minutes apart). The white indexes are luminous, they glow in the dark to allow time reading in low light conditions as well. 
 
AEROPOROS is powered by a Japanese NH-36 automatic movement, oscillating at 21,600bph (beats per hour) it is well known for its reliability and accuracy. Using a bi-directional winding system, it effortlessly captures your every action and movement recovering your energy to wind up and power the watch. The NH-36 movement can store up to approximately 40hours of power reserve, so it will be ready to accompany you on your next adventure. Besides that, NH-36 offers day and date indicator to keep track of your calendar. With an option of English or Spanish written day indicator as well.
 
To ensure the NH-36 movement is well protected, it is cased inside an aesthetically pleasing yet strong cushion style stainless steel 316L watch case. At 43mm diameter, which many considered within the golden ratio of watch size. The AEROPOROS will conform to most wrist sizes comfortably. Domed sapphire crystal is added to the front for better strength and less glare compared to flat sapphire crystal. The back of the watch is transparent, with sapphire crystal protecting the winding rotor while providing a nice viewport. The crown of AEROPOROS is screw-down type to enhanced water resistance. The combination of all these elements allowed AEROPOROS to withstand up to a rated 20ATM (or approx. 200m) of water resistance.
