Longines is one of the very oldest Swiss watch manufacturers with an unparalleled history of invention, innovation, patents and awards. It is also responsible for some of the most exquisite watches, and watch movements, ever produced. The very highest accolades are reserved for its achievements in the development, and indeed the invention, of the wristwatch chronograph. Just a brief glance inside a chronograph, from any era, is enough to convince one how great an achievement this was. Released as early as 1913, Longines’ Calibre 13.33Z was a huge technical breakthrough. Early aviators and sports events, such as ski championships and motor racing Grand Prix, all relied heavily on the most technologically advanced and sophisticated chronographs available at the time, almost all supplied by Longines. Further, in 1919, Longines was appointed the official supplier for the International Aeronautical Federation (IAF) which led the company to be involved in many aeronautical expeditions during the early 20th century. The most famous of them was Charles Lindbergh’s solo, non-stop flight from New York to Paris in his aircraft, “Spirit of St. Louis,” in May 1927.
It is also worth mentioning here that due to the technical challenges and sheer costs involved in development and manufacture, very few watch companies, even today, make their own chronograph movements. The largest producers of these movements for high-end watches throughout most of the 20th century were the relatively unknown brands of Valjoux and Lemania. For example, before 2000, Rolex used Valjoux 72 and Zenith El Primero movements in both its Daytona and Chronographs.
Why This Watch Is Important
One of the truly great “in-house” chronograph movements began its development in the 1920s. First released in 1936, it was so beautifully designed and so elegant and well engineered, it remained in production with changes and upgrades until the early 1970s. This was the now legendary Longines Calibre 13ZN Flyback Chronograph, which is the movement you see here. It was and still is considered better than the best from Patek Phillippe at the time. Longines had earlier determined it would build on its early lead in the chronograph market by only focusing on this one aspect of ‘complicated’ watches, namely the chronograph movement. The 13ZN remained the most technologically advanced chronograph movement available for many years after its launch. It was the first wristwatch chronograph movement to be equipped with a ‘Flyback’ mechanism. It was no coincidence that this function was of great use in the field of aviation. This function allows the chronograph to be reset while it is actually running. This allowed a pilot to continuously monitor the time he or she had followed a course, then while changing course, stop, reset, and restart the chronograph with a single click of the lower button, rather than the three clicks on two buttons this would take on a normal chronograph. While this may sound simple, virtually no other manufacturer attempted to produce a flyback mechanism, in a chronograph, until 20 years later with the advent of the Type XX chronographs produced for the French military.
Note: This particular watch is also important for other reasons. Please see ‘Watch Case’.
Black dial watches with pink gold watch cases are always, we think, something rather special. Due to the requirements of the military forces which very often specified back dials for military chronographs, this style became popular among the buying public during the post-war period. Here, this two-register dial is brimming with 1940s charm and style. All five original unrestored hands are present and in wonderful condition. The ‘Alpha’ style hour and minute hands are complete with their original rose/pink gilt finish.
Large standard Arabic gilt numerals make the dial very legible, even in low light, and around the outside of the dial we see both a Telemetre scale and a Tachymètre scale. The former was designed to measure the distance between an event and an observer, using the speed of sound. In wartime, this was essential for timing the difference between the flash of a large gun emplacement and the arrival, some seconds later, of the sound of it firing. The distance was calculated using the speed of sound, and easily read on a telemetre scale. The Tachymètre scale was simply used for calculation of speed over a measured distance. These give a feeling of the true technical nature of chronographs and the essential tools, indeed computation devices, these once were.
The dial is believed to be original and unrestored, although this is difficult to guarantee. We have canvassed a number of opinions on this, as it is incredibly difficult to be totally sure if and when a dial restoration has been carried out, many years ago. If this is the case, we feel this is as close to an original unrestored dial as one is ever likely to see, certainly in such top condition as this. It is for these reasons we have left the dial completely alone. If however, a customer would prefer a restored dial, we will restore this dial free of charge.
The Watch Case
At 37.5mm excluding the correct Longines crown, this is, we feel, the perfect size for such a watch. The colour of the case has an ‘old gold’ look, almost a dark yellow with a hint of red and is very pleasing on the eye next to the black dial. In 18ct pink/rose gold with military style short lugs, this heavy three-piece case has remained in amazingly good condition. It is in fact absolutely immaculate, with no scratches, dimples, dings or other marks visible to the naked eye. This, along with the condition of the dial and movement lead us to believe this watch may well have spent most of its life in its box. The block script inscription on the case-back remains distinct, which also indicates very little use.
The case-back is fascinating itself. 1947 was, as anyone who has studied the history of the British Empire will know, a very important year – the year of the end of British rule in India. Louis Mountbatten was appointed as the last Viceroy, solely to handle this huge challenge and for anyone interested in learning about this truly fascinating period, the wonderful book, ‘Freedom at Midnight’ is essential reading. This watch was a gift during the final year of British rule in India, from His Highness Prince Muaz Azam Jah of Hyderabad, otherwise known as Prince Azam Jah. Azam Jah, 1907–1970, was the eldest son of the seventh and last Nizam (monarch, king and ruler) of the Princely State of Hyderabad who during the 1940s was the richest man in the world with a fortune worth $2 billion USD, approximately $300 billion adjusted for inflation today. The recipient of this watch, Mr J. Maxwell Esq., was no doubt a high ranking official within the coveted Hyderabad Civil Service which was considered to be an elite service, and one which only the best of the government officers were inducted into, through a competitive examination. Anyone reading this who can throw any further light on a Mr J. Maxwell acting in this role, during this period, will be most welcome to contribute further to this section. He was surely most fortunate to be given such a watch, the most expensive available from Longines and one of the most expensive watches on the market at this time.
The Longines 13ZN has been heralded by collectors and enthusiasts for decades and it is safe to say it has gained easy entry into the pantheon of definitive timepieces. This is simply the most advanced and sophisticated chronograph movement available of its time. Its design, sophistication, dependability and accuracy each contributed towards it remaining in production for almost 40 years. Its ‘Flyback’ function, enabling a chronograph to be stopped, reset, and started with one push of the button, is something so technically challenging, it is only found on the most expensive chronographs, even today. The exceptional nature of the 13ZN sometimes surprises those who are more familiar with contemporary offerings from Longines. Indeed, it was a top tier manufacture during the 1940s and ’50s, creating in-house movements and complications which rivalled the comparable offerings from Patek Philippe of this period.
Operation – The chronograph function operates in much the same way as most others, in that the large central seconds hand is started and stopped by pressing the top pusher. Once stopped by the top pusher, the seconds hand is then reset to zero by pressing the bottom pusher. The huge difference with a flyback chronograph movement such as here is that once the seconds hand is running, it can also be stopped, reset and started again with one single click of the bottom pusher! This is very useful for example when timing laps. The right-hand dial registers up to 30 elapsed minutes while the chronograph is running. The left-hand dial registers running seconds, independently of the chronograph. So as long as the watch is running, this dial is registering seconds.
As can be seen in the accompanying photographs, the condition of the movement is, in keeping with the rest of this watch, in spectacularly good condition. It has just been overhauled and serviced by our vintage chronograph specialist watchmaker and it now has a silky smooth operation, with all the functions operating exactly as they should. The seconds hand flys back exactly to zero, exactly as it should. The normal watch movement is keeping excellent time to within +9 seconds in 24 hours. This is outstanding for any watch of this age and we are more than confident in offering this watch with our 12 months’ warranty on the movement*.
*Please note – our 12 months’ warranty is only applicable provided the list price is paid.
Please note – as with all wristwatch chronographs, these movements have two distinct functions, i.e. telling the time, and accurately recording short time intervals. However, these are not intended to be run continuously together for long periods of time. This will, in effect, cause the watch to keep less accurate time and will also prematurely wear the chronograph movement. We therefore recommend against leaving the chronograph function running on any chronograph wristwatch.
The movement serial number is 7280250 indicating this movement was manufactured in 1946.
