After the best part of six months of procedures and thorough investigations, Louis Moinet has become the official holder of the title of “First Chronograph”, awarded by the official Guinness World Records organisation.
In bestowing its Guinness World Records award, the worldwide authority brings further recognition of a fact already widely acknowledged in the world of watchmaking: the chronograph was first invented by Mr Louis Moinet in 1816, with his “Compteur de Tierces”.

Chronometer versus Chronograph: What is the difference?

According to Thesaurus, a watch is an apparatus fo measuring and recording the progress of time. Obviously in the past 300 years watches have become more than just timekeeper objects. Several watchmaking complications joined the field of possibilities.
Chronometer: A name that is given to only watches with the highest precision standards. These watches have passed rigorous testing of the Swiss Official Chronometer Control which consists of 15 days under various conditions like exposure to different temperatures, positions or water levels. Obviously only watches made in Switzerland are controlled in terms of the Chronometer usage. All watches that have been produced abroad cannot be controlled.
Chronograph: A watch that has a stopwatch capability. It is a watch complication. Timepiece capable of measuring extremely brief intervals of time accurately, as a stopwatch able to record fractions of a second as well as elapsed time. Its counter can measure elapsed time in seconds, minutes and hours. The term, Chronograph comes from the Greek word for time, “chronos”, combined with the Greek word for writing, “graph”. It was Nicolas Mathieu Rieussec who developed the first marketed chronograph at the behest of King Louis XVIII in 1821. The King greatly enjoyed watching horse races, but wanted to know exactly how long each race lasted, so Rieussec was commissioned to invent a contraption that would do the job: as a result he developed the first ever commercialized chronograph. Rieussec was considered the inventor of the chronograph until the Louis Moinet pocket chronograph discovery in 2013 when history was rewritten.

Louis Moinet, father of the first Chronograph

Louis Moinet’s profile is an outstanding one. Son of a French prosper family of farmers, Louis Moinet decided to do studies in Arts and Architecture. After living a couple of years in Italy, he got back to Paris and became a teacher in Fine Arts at Le Louvre. In parallel, he also began his theoretical and practical studies of watch making, an art which he already loved most passionately. He reestablished contact with his former master watchmaker and, within less than ten years, the master was to find himself in the position of student to Moinet. Watch making soon engrossed all of Moinet’s time and its tools brought him frequently to Switzerland where he spent extended periods of time.

Quite fast, Louis Moinet became the President of Chronometry Society of Paris which allowed him to meet several influent people at that time. One of them was Abraham-Louis Breguet. Breguet recognized that Moinet had a lot of talent and decided to work closely with him and in 1811 he became Breguet’s personal advisor. Among his many technical accomplishments, Moinet re-made a Ferdinand Berthoud regulator almost in its entirety. He also invented a counter that, even today, is unequalled. The same can be said for another regulator and an astronomical watch. In terms of watch making techniques, Moinet was a genius and he improved upon many existing methods. He was so inventive that he wrote a new treated about watchmaking – Nouveau Traité Général d’Horlogerie.
Louis Moinet is in particularly renowned for his famous Traité d’Horlogerie, published in 1848 and widely reputed to be the finest book on horology of the century. Comprising descriptions of the finest watchmaking techniques, it was appreciated by the great watchmakers of his era such as Frodsham, Perrelet, Saunier and Winnerl, as well as by several other scholars and connoisseurs such as HRH Prince Alexander of Orange – all of whom appear on the list of the numerous subscribers to a book that was reprinted three times and circulated as far afield as Russia.
In the 19th century, watchmakers sought to increase the precision with which they could measure time by increasing the frequency of their watches. By 1820 the generally accepted limit was time measurement to the tenth of a second. Moinet’s compteur de tierces (“thirds timer”) was thus by far the most precise instrument of its period, measuring time six times more closely than the norm. Moinet’s division of time into sixtieths of a second is another historical achievement that places him among the great contributors to modern watchmaking. The chronograph’s balance beats at 216,000 vibrations an hour or at the then unimaginable frequency of 30Hz. To put that into perspective, the usual balance frequency in a modern wristwatch is 28,800 v/h or 4Hz. Louis Moinet is thus the father of high-frequency time measurement, although it was not until exactly a century later that a watch was made to beat his record.
