Having a love for complications and complicatedwatches, makes me love Chronograph watches. At first two register chronographfor simplicity of the dial and providing chronograph functionality for themost. Then the three-register chronograph for the complication of movement andthe history of the movements, like of the iconic Omega Ref. 321, Ref. 861 (usedin famous moon landing), Zenith El Primero, Venus mostly used in Breitlings,Landeron, and one of the most well-known movement makers Valjoux. With theirfamous Valjoux 72 put in the vintage Rolex Pre Daytona’s and of course the bigdog Patek Philippe reference 2499 using Valjoux 88 my favorite which sold inauction for $3.30 Million in 2018.  Ialso love the Heuer Caliber 11 first micro automatic chronograph movement withdate.

A Chronograph is simply a watch that combines thefunction of a stopwatch with a timekeeping display watch, by utilizing anindependent sweep second hand. Chronographs often have complications on theface of the watch which can be used to record different time measurements, mooncycles, heart rate and more. Chronographs have usually have a separate buttonsto stop, start, and reset (unless it is an monopusher) the stopwatchcomplication, with the start button typically at the two and four o’clockposition.

The name Chronograph is derived from the Greek words‘Chronos’ – the personification of time – and ‘graph’, meaning to write. Thefirst modern Chronograph was created in 1816 by French watchmaker, LouisMoinet. Invented solely for use in union with astrological equipment, Moinet’sChronograph could measure time accurate to 1/60th of a second – an unrivaleddegree of precision at the time of its creation.

"poor man's" Heu-ers represent an interestingfacet of Heu-er's history and also provide a sensible way for individuals tocollect these chronographs on a more reasonable budget. The term "PoorMan's Heu-er" only to refer to chronographs manufactured by Heu-er forother brands one of which is Zodiac & Clebar, which is one of my favoritebrands. Please note on ebay there are few brands that are not made by Heu-erand still refer to as Poor man which is not true.

This is a beauty. Super rare and ultra-cool first generation Movado Datachron HS360 Super Sub Sea diver’s chronograph featuring the debut version of the legendary Zenith/Movado “El Primero” automatic movement. The movement has 17 jewels rather than 31 and means this watch was destined for the US market and the fact that the dial is signed DATACHRON rather than the later and more common DATRON proves that this is one of the first El Primero Sub Seas ever produced. Defiantly a collector watch.
