Citizen Chrono Time A-T Eco-Drive Grey Dial Stainless Steel Men’s Watch Day Date ref. BY0100-51H is Chrono Time A-T second-generation line which carries now even more of that innovative technology which powerfully enhances this time instrument. 

This Chrono Time is known for its Radio controlled Atomic Time synchronization across four regions of the US, Europe, China, and Japan for superior accuracy of world time. 

It also features complementing grey dial with an analog timekeeping and functions such as chronograph, second-time zone, date, and tachymeter. 

Creatively, the subdials are presented in three-dimensional look, engraved through with printed markings for 12/24 hour, 60-minute, and 60-second measure. On the 4 o’clock position, the date and 26-city indicator for the dual time function. 

It displays time through applied big Arabic and bar hour markers and silver-tone hands that are both luminous, extending its time-telling capacity even at the darkest hours.

An additional feature to this watch is the Tachymeter scale, which is engraved at the fixed stainless steel bezel, used to measure travel time based on speed. Securing the display performance is a tough sapphire crystal with shatter resistant properties. 

This watch has Citizen’s invented Eco-Drive green movement that converts light power to electrical energy. The watch panel (under the dial) can virtually use any light source, natural or artificial, to be converted into electrical energy. Eco-Drive features a lithium-ion cell storing this energy.

This means you do not require any battery replacement, charging or winding to maintain constant operation. Eco-Drive is ecologically friendly as it does not need battery replacement which is very polluting to the environment.

A typical Eco-Drive will work for at least 6 months, even if stored in the dark.

It is encased in a silver plated polished stainless steel case sizing 44mm wide.
