CTK14- Three Hands Automatic – Jade Limited Edition

Finding its inspiration in the footsteps of its illustrious Chinese ancestors, The Chinese Timekeeper is paying homage to Su Song’s revolutionary clock tower. Indeed several distinctive elements of a CTK timepiece have been designed with the work of Su Song in mind.

Notably so is the revolutionary shape of the case which has been ingeniously engineered to respect, first with an oversized diameter of 44mm, the round and impressive shape of Su Song’s Great Driving Wheel. The central wheel was large of 3.35m in diameter and carried 36 scoops on its circumference, taking in excess of 9 hours to completely fill and consuming in the process about half a ton of water.

Secondly, the other central piece in Kaifeng’s clock tower was the five-story pagoda from which bystanders could hear and see the display of time. Based on the architecture of an Ancient Chinese Pagoda, the case of a CTK is strikingly composed of four layers or rings made of stainless steel 316L, which are held together by four large screws on the bezel and four smaller screws on the back case. The preeminence of the screws is reminiscent of the roughness of the construction of the old tower.

Another element worth noting on a The Chinese Timekeeper lies in the construction of its breathtaking buckle. Chinese astronomers, to understand the heavens used a tool known as an armillary sphere. The construction of an armillary sphere, or celestial sphere, consists of a series of nestled rings, also named Circles of Heavens that rotate on a single axis around the Earth. Hence a CTK buckle, derived from the armillary sphere, has a never seen before shape representing one of the circles of the Heavens.

Let’s turn our attention to the dial, which has for particularity to have the Chinese character ‘十‘standing in place of the numeral 10. Most of the time in red, offering a great visual impact, is yet another link to the Chinese culture. Indeed, the number ten reminds of the famous Chinese saying “十全十美” meaning beautiful, complete or even perfect.

About The 12 ‘double hours’ system & Triple System of timekeeping

Since the times of ancient China, three timekeeping systems have been used, sometimes simultaneously.

The 12 ‘double hours’ system: The first was a system of dividing the full day into 12 ‘double hours.’ The first of the double hours started at our modern equivalent of 11 pm, therefore lasting until 1 am. Each of these divisions was associated with a sign of the zodiac – starting with Tzu designating the Rat. In medicine, the 12 double hours are divided into four categories representing the seasons.

The 100 ‘quarters’ or “Ke” system: The second system is the division of the full day into 100 ‘quarters’ or ‘ke,’ equivalent to 14 minutes and 24 seconds. As time went on, this system was modified into 96 or 120 ‘Ke’ in order to be divisible by 60 and be in line with the duo decimal system. However, these reforms were never successful.

There were no dials, nor hands to display the time, but rather a wooden statuette, a statuette that became the keeper of time for 14 minutes and 24 seconds, embodied each quarter. These manikins, representing the eternal running of time, inspired The Chinese Timekeeper’s logo.

The five ‘night watches’ : The third system was the five ‘night watches’, a system therefore only applicable at night, as the sunset to sunrise was divided into five ‘Keng,’ each of which is again subdivided into five ‘Ch’ou’.

Chinese Timekeeper – Historical Connection

Time and China – The beginning

Timekeeping in China can be traced all the way back to its first dynasty, the Shang (1600BC until 1100BC). During that time, people were mostly rural farmers and did not need to know the precise time. Therefore the day was only separated into two sections: ‘Ch’u’, which was from ‘just before dawn’ and ended with the morning. The second part of the day, called ‘Cheng’ went from midday until ‘just after dusk’.

In agriculture, drums and trumpets were still used to dictate the time, but varied greatly with weather, seasons, and farming requirements. In city life, craftsman could only work until the last glimpse of natural light.

For the Emperor’s servants punctuality was replaced by circumstances and productivity was measured by one’s ability to stay busy. However under the commandment of the emperor a great number of astronomers and engineers paved the way of today’s watchmakers with their crucial inventions. Those are such men:

Armillary Sphere: Zhang Heng’s Heritage

Zhang Heng (78-139) was Han dynasty’s most influential scholar. He is credited with several major accomplishments. Amongst many inventions, Zhang Heng created the first seismometer, which allowed the Han Government to send quick aid and relief to areas devastated by earthquakes. Many lives were saved as a result of its speed, accuracy and effectiveness.

Zhang Heng’s Heritage for the horology arises from his invention of the first water driven armillary sphere, which shows the workings of the celestial sphere considering a point of view from Earth. Astronomers and other scientists to understand the heavens used this device. So is The Chinese Timekeeper with its unique buckle respecting the shape of one of the Sphere of Heavens of an armillary sphere.

Gears: Ma Jun’s Heritage

Ma Jun (220-265) is known as one of the most brilliant mechanical engineers and inventors of the Three Kingdoms era of China. His most notable invention was that of the south pointing chariot, a directional compass vehicle that actually had no magnetic function, but was operated by use of different gears. Even though Ma Jun did not apply his invention to timekeeping, he created one of its decisive characteristics: mechanical gears.

Indeed, he was the first combining the use of different gears, which applied equal amount of torque to driving wheels rotating at different speeds. This physical theory is one of the leading principles in any mechanical watch, which now use a combination of dozens of gears. Every The Chinese Timekeeper watch is a beautiful reminder of the long forgotten origins of this central element.

The escapement: Yi Xing’s Heritage

Yi Xing (683–727) was a Buddhist monk around whom many legends have grown. Only a small portion of his work has survived so it is difficult to appreciate it in detail. There is, however, no reason to doubt his involvement in two major astronomical achievements, with one particularly relevant for modern timekeeping: the measurement of the length of a meridian line and the invention of the first water driven escapement.

In mechanical watches and clocks, an escapement is a device, which converts continuous rotational motion into an oscillating or back and forth motion. Without this device, there would be no mechanical clock. A water driven escapement was also present in Su Song clock tower and as such one of the greatest achievements that The Chinese Timekeeper pays tribute to.
