Ball Trainmaster
Doctor Chronograph

The inspiration behind limited edition Ball Trainmaster Doctor Chronograph is none other than Dr Christopher Hillman, a doctor who extends his medical expertise beyond borders. Moving among villages high up in the Himalayan Mountains (up to 14,000 feet above sea level), reliability of his instruments at such extreme conditions are critical to his work. Furthermore, he depends on accurate timing during the basic physical examinations of pulse, heart rates and respiration. It is therefore of no surprise that Dr Hillman finds the Trainmaster Doctor's Chronograph to be a worthy companion on his work.

Ball Trainmaster Doctor Chronograph uses the automated Ball Caliber 350 (base ETA Valjoux 7750) that vibrate at 28,800 times per hour. 25 jewels are included in the movement. It has a 42-hour power reserve. The yellow gold case is 43mm in diameter with a height of 15.5mm.

It has a screw-in crown and a screw-down sapphire crystal exhibition case back that offers a glimpse of the exquisite workmanship. The face is made of anti-reflective sapphire crystal. The main functions are hours, minutes, subsidiary seconds; monopusher chronograph; date, day and month aligned at 3.

Ball Trainmaster Doctor Chronograph simplifies the measurement of one's pulse frequency. A single-button chronograph movement allows the start, stop and reset functions to be activated for quicker measurement and minimal human error.

The watch is graduated for 15 pulsations and the pulse per minute can be read off using the red scale on the dial. The Ball Trainmaster Doctor Chronograph has 15 micro gas tubes on its hands and classy enamel dial, for easy night reading. Shock-resistant to 5,000Gs and water-resistant to 50m. The band is made of crocodile skin complete with a 18-karat gold buckle. Variations include a rose gold or platinum case.
