Graham- Green Han

In addition to the blueprint of George Graham, Gringham brand watches also inherited the spirit of his courage to innovate in function design, and each watch is amazing. Green Han series series are mainly based on time stopwatch, such as Chronofighter series, Silverstone Silverstone series, Foudroyante1/8 second lightning chase needle chronograph, Aeroflyback fly back ranging timing stopwatch and so on.


With the flourishing development of the Swiss watch industry, many people may never notice that the real origin of the tabulation industry is actually Britain. The history of the watch making industry originated in seventeenth Century, when the Royal Navy Fleet expanded its territory and vision. The calculation of longitude position became a very important part of the world. In 1714, the Royal empress of England, in order to encourage the early development of the method of longitude calculation at sea, held a special contest called the Royal longitude computing instrument competition.


The British masters of every generation of watches and clocks have been able to inherit and add new ideas to the invention of technology and concepts. If George Green Han was the first person to invent the timer, the great watchmaker was called the father of the timer. The world's first pendulum clock invented by ThomasTompion is still in the Royal Greenwich Observatory. John Jano was the first prize winner of the Royal longitude computing competition, and the navigation timers he made were necessary instruments for all the expeditions. These unique and important inventions have not only established their status as masters in the history of clock making, but also have played an important role in today's watch making industry.



George Green Han's remarkable invention includes anchor escapement system, aperiodic escapement system, mercury compensated pendulum, and regulator's table. These inventions even have a place in the watch industry today. He also inventions mechanical design, careful and practical functions, and never hesitate to share new inventions with his peers, so that George, Green and Han are highly praised by the British watch industry. In addition to GeorgeGraham's work as a blueprint, Gringham's brand watch also inherited the spirit of his courage to innovate in function design. Green Han series series are mainly based on time stopwatch, such as Chronofighter series, Silverstone Silverstone series, Foudroyante1/8 second lightning chase needle chronograph, Aeroflyback fly back ranging timing stopwatch and so on.
