Based on doctor’s watches from the twenties, the Longines Pulsometer Chronograph is a mono pusher with a red pulsations scale and a lacquered enamel dial.

At Baselworld 2015 Longines has once again introduced a vintage-style chronograph powered by an upgraded Valjoux movement at an affordable price. The Pulsometer Chronograph is styled like those twenties chronographs intended for doctors, with a scale for measuring heartbeats on the dial. The dial is lacquered white to resemble fired enamel, printed with black Arabic numerals and fitted with blue steel Breguet hands. The case is steel and 40 mm in diameter with a display back that reveals the L788.2 movement inside.

It’s derived from the ETA Valgrange movement, itself based on the Valjoux 7750, but upgrade with a longer power reserve of 50 hours as well as a column wheel. And it is a single-button, or mono pusher, chronograph, with one button integrated into the crown to start, stop and reset the stopwatch.  This is the same movement found in the Single-Push Piece Chronograph introduced in 2013, pictured below.

The Longines Pulsometer Chronograph will cost 6360 Singapore dollars.
