Ball Watch Train Master KELVIN NT3888D-LL1J-GYC Automatic Gray Round Analog Men. BALL WATCH Kelvin automatic winding. Ball Watch is the first in the world to equip a self-winding watch with a thermometer.We have created epoch-making functions and structures. And it is a self-winding watch named after Kelvin, who is also a British physicist who is closely related to thermometers and is also a unit of absolute temperature.
Ball Watch's TMT movement is the world's first mechanical wristwatch capable of measuring from -35 ° C to 45 ° C. Bimetal is used for the thermometer, and it boasts much higher accuracy than conventional thermometer modules. When the project to incorporate a mechanical thermometer into a wristwatch was launched, it challenged the difficult problem of limiting the thickness of the module mounted on the movement to just 5.1 mm. Ball Watch R & D members have overcome a number of design obstacles by reviewing the thickness of the bimetal and the size of all parts such as the base plate and receiver.
Ball Watch's TMT module is equipped with a unique screw-type adjustment device that allows fine adjustment of the temperature display without interfering with the movement of the bimetal. This adjuster not only accurately adjusts the position of the temperature indicator needle, but also fixes the end of the bimetal coil.
After setting the needle on the shaft of the thermometer, the measurement accuracy can be inspected and the expansion and contraction of the coil can be strictly controlled. Finally, we also perform a rigorous impact test to withstand large impacts.
When wearing a wristwatch, the temperature display will be incorrect due to the influence of body temperature. Micro gas light The self-luminous micro gas light (3H) is a new light created by Swiss innovative laser technology. It is used in all ball watches, and it does not need to be lit by light or use batteries, and it always shines in any environment and can read the time.
