Brief History: Longines Watch Company

Brief History: Longines Watch Company 
Including Serial Numbers & Production Dates 1832 - Present

Longines
In the early 1800's Swiss watchmaking was truly a cottage-industry. Watches were produced using the "etablissage" method, where individual tradesman working out of small studios or their homes would produce parts (or sub-assemblies) which were then assembled and sold under the auspices of a single brand. In 1832, Auguste Agassiz began selling etablissage-produced watches under the name "Agassiz & Compagnie" and was particularly successful selling those watches in North America.

In the 1850's, Agassiz passed control of his company to his nephew, Ernest Francillon. Francillon wanted to modernize the production of watches and believed that bringing all the final assembly and finish operations together into one factory would be a more efficient method of production. To accomplish this, Francillon built a factory on a piece of land known as "Les Longines" and the Longines brand was born. This method of production proved to be very successful, and by the early 1900's the Longines factory employed over 1000 people and had achieved worldwide distrubution and success with its products.

The Longines "Winged Hourglass" (actually a winged clepsydra for those who care about such things) is the oldest registered trademark for a watch company, having been registered in 1880. The Winged Hourglass logo first appeared on Longines watches in about 1867.

Longines Chronographs in Sport and Aviation

Longines was the first company known to have created precision timers for sporting events. They pioneered the "broken wire" system, as well as the first "photo finish" mechanism, which linked precision timing with a photographic record of the event. Longines timers are still used in many sporting events, especially equestrian and gymnastics competitions. Longines produced some really beautiful sport chronograph watches in the 30's and 40's, using Longines own in-house movements. Original Longines chronographs are very collectible.

Longines was also famous for their Aviator's watches. After his historic flight, Charles Lindbergh helped Longines design a pilot's watch with special features for air-navigation. Longines is also the official timer of the World Air Sports Federation, and has provided the timing equipment used to verify world aviation records, including Lindbergh's historic first non-stop solo crossing of the Atlantic. Aviation pioneer Amelia Earhart was also known to have worn a Longines watch, which is described here.

American Watch Manufacturers: Production Summary

 How many watches were produced by American watch companies? When looking at the total output of American watch manufacturers, a natural distinction can be made between companies producing higher-quality jeweled pocket watches and those producing lower-quality "dollar-style" (or otherwise minimally-jeweled) watches. Over 500 million low-cost watches were produced by companies like Ingersoll, Ingraham, New Haven and Ansonia, accounting for a large percentage of total US production. We are more concerned with the production of higher-quality, jeweled pocket watches of at least seven jewels; the type that might be considered collectible today. Obviously, a rare watch tends to be more valuable than a common watch, so an understanding of which companies made more or fewer watches is worthwhile information for any watch collector. The passage of years and incompleteness of factory records means that it is probably impossible to create a completely accurate accounting of American wa...

Unique Artisan Watches

 As you might have heard, most of the pocket watches produced at the end of XIX beginning of the XX centuries originally had their cases made of precious metals. Then, during the war, many antique pocket watch movements had become orphaned from their original cases. As the result, these movements remained uncased, and we found vigor in restoring and preserving the beautiful pieces in a functional way. By reverse-engineering antique parts, we were able to create a wristwatch case that housed the pocket watch movements in the same way as the original pocket watch case. To make these historical quality time machines wearable again, we create a modern wristwatch case individually for each movemen We produce two different types of cases that gently hold the movements: cast cases and chiseled cases. We also have some ready-to-wear stainless steel cases. The stainless steel cases usually have the bezel redesigned to make them look unique. Most of our cases are made with the exhibition bac...
