The Ball Trainmaster Pulsemeter Chronograph II
The Ball Trainmaster Pulsemeter Chronograph II is named and designed with doctors and healthcare professionals in mind. Its namesake function is to quickly tell someone's pulse rate the "old-fashioned" way.
While the watch is similar to other Trainmasters in that it has a display back, and similar to other Ball Chronographs in its use of a 7750 based movement, what sets it apart is the pulsemeter scale on the outer edge of the dial. The pulsemeter scale is numbered from 160bpm-17bpm and is very easy to use. The markers are precisely spaced on a graduated scale designed to "calculate" heart rate in bpm from only 15 pulses. After locating someone's pulse, you engage the start timer and count the pulses. After you've counted 15 beats, you stop the timer and look at the number on the scale. For example if it takes 20 seconds for a person's heart rate to reach 15 pulses, their beats per minute (bpm) is 45, which would be an abnormally low heart rate. If it takes 10 seconds then the bpm would be 90 which would be a more normal resting heart rate.
As for the watch itself, it is a 42mm case that is 15.65mm thick. Compared to the Pulsemeters of the past, the dial is relatively understated. The biggest aesthetic features are the raised arabic numbers and slight sunburst pattern. These design attributes are similar to the popular Cleveland Express models. This model offers black and silver variations where the contrasting markers and hands are the color of rose gold. There is also a dark grey model where the contrasting markers are steel colored. Below are photos of the three available dials. All configurations are $3,999.
