During the course of a hectic day, doctors like Dr. Hillman in the Himalayas and the local ER doctors must monitor the progress of their many patients to ensure a speedy recovery. The Ball Trainmaster Doctor’s Chronograph transforms this into an easy task. When the doctor stops the chronograph, the pulsemeter scale displays the exact pulse for him, with no complicated calculation required./
The month, day and date are displayed in a single row at the 3 o’clock position, an innovative BALL in-house. The other Ball modification, the single-button chronograph, allows quick measuring of pulse or respiration.
