Completely reliable functions, perfect ergonomics and convenient operation - it's immediately obvious this is what the Model 144 was designed for. But there are a few more things you should know: for example, that we use a first-class Swiss movement, as in all our timepieces. In this case it's a Valjoux 7750 to be precise. This guarantees the highest standards of accuracy. The movement is well-protected by the solid, compact case with sapphire crystal glass. Other features include a small second counter, 12-hour counter, jumping 30-minute counter and a stopwatch second hand in the center. All this is complemented by the useful tachymeter / pulsometer scale and a date display that also shows the weekday.
