With the new Heritage Single Push Piece Chronograph, Longines is again moving in the right direction. And what a comeback piece!
The monopusher collection gets its inspiration from their vintage piece. They have three timepieces in their current collection - the Longines Pulsometer Chronograph with the black and another the white dial plus the Heritage Chronograph - without the Pulsometric scale. All timepieces are 40mm - very comfortable to wear IMHO.
The Pulsometer scale allows a medical professional to take the heart rate reliably and quickly by using the scale. Instead of taking one minute, the scale allows the user to take the heart rate in 30 beats instead. And this invention was developed in the 1920s.
I believe this range will take to collectors and also will be on many collectors' wish lists. I also posted about the Montblanc Villeret Vintage Pulsographe which also has a Pulsometric scale but the pricing is way higher than this Longines monopusher.
