Limited Edition of 600 pieces.

William Thomson, 1st Baron Kelvin, an Irish and British physicist and engineer born in 1824 in Belfast, was a pioneer in developing the absolute thermodynamic temperature scale. In 1848 he proposed in his paper, on an Absolute Thermometric Scale, the need for a scale whereby infinite cold (absolute zero) was the scales null point, and which used the degree Celsius for its unit increment. Lord Kelvin further calculated that absolute zero (the temperature at which all thermal motion ceases) was approximately equivalent to 273 C. This absolute scale is known today as the Kelvin scale, and the Kelvin (K) has since become a unit of measurement for temperature. Scientists nowadays have achieved temperatures extremely close to absolute zero, where matter exhibits quantum effects such as superconductivity and superfluidity.

Like Lord Kelvin in the scientific field, Webb C. Ball can also lay claim to the same pioneering role in the history of watchmaking, as he introduced the first chronometry standards used by the American railroad companies. The system developed by Webb C. Ball at the end of the 19th century was based on such stringent precision criteria that it was used by the Official Swiss Chronometer Testing Institute (COSC) as the basis for its own certification system in 1973. These same values of precision and reliability shared by the measurement of time and temperature have inspired BALL Watch to create a watch that celebrates the memory of Lord Kelvin.

This timepiece is included in the ñTrainmasterî series with its models that naturally hark back to the first watches bearing the BALLs Standard marking and which ensured the safety of trains thanks to their unparalleled precision. The Trainmaster Kelvin has naturally been equipped with the BALL RR1601 caliber including the TMT mechanical thermometer module. This function, developed and patented by BALL Watch, measures the outside temperature between 31F and 113F (-35C and 45C) with an accuracy of 97% that only a mechanical thermometer can achieve. The thermometer readings are given in increments of 18ÁF (5C) in the half-moon shaped window at 6 oÍclock on the dial.

BALL Watch produces its TMT module using bi-metallic materials of the highest quality. Bands are carefully wound, heat treated, cut according to very precise specifications, their ends folded and then laser welded. The plate and bridge are then custom-manufactured. BALL watchmakers place, decorate and then assemble the jewels and pins. The same procedure also applies to the patented screw adjustment system. This essential component ensures extremely high temperature measurement precision by stabilizing the position of the bi-metallic coil while still allowing it to expand or contract in response to the changing temperature.
