Just as with any other precision instrument, a watch needs to be maintained regularly to ensure faultless performance. Generally speaking, the watch should be serviced every 4-5 years. This, of course depends on the wearer and the amount of stress the watch undergoes in everyday life.

We also recommend that you have your Longines watch checked for water resistance once a year as natural wear and tear can cause seals to become loose.


  • Our horologist will examine every aspect of the timepiece to pinpoint any areas that require replacement.
  • The inner components will be specially lubricated in order to minimise friction that leads to excess wear.
  • The balance wheel will be tested expertly to ensure it’s perfectly precise and keeping time as it should.
  • The watch strap will undergo with specialist cleaning and examination of wear and tear; any parts that are damaged will be refurbished or be replaced with genuine or aftermarket components.
  • If your watch has a quartz mechanism, the battery will be replaced.
  • The mechanism is carefully reassembled and reattached to your watch’s strap with every seal replaced.
  • The timepiece will be methodically tested one last time to ensure the timepiece is still absolutely waterproof and precise.


To keep your watch in top condition between systematic servicing there are some ways you can protect the health of your watch:

  • Keep your Longines watch clean with a soft dry cloth; do not use water in case there is a loose seal.
  • Avoid contact with perfumes, spirits or petroleum products as these may damage seals, straps or case/bracelet.
  • Ensure that the crown, which is used to change the hands/date, is properly pushed in and/or screwed at all times. This prevents infiltration of water or dust.
  • Avoid knocks and bumps as scratching may eventually affect the case and bracelet. If you are about to undertake heavy physical work, always remove your Longines watch.
  • If your watch has a leather strap do not or expose it to water as this could damage the function and look of the strap.
  • Avoid your watch being exposed to rapid changes in temperature, unless of course you own the Longines 276 VHP.
  • When not being worn, keep your watch in a cool dry place and keep out of direct sunlight; as this can damage the movement if exposed to temperatures above 60 degrees.
  • Do not wear your watch at the beach, salt water and sand can corrode the delicate intricacies of your time piece.
  • If the battery dies, send it for watch battery replacement immediately as the dead cells may cause damage the mechanism.


Longines has a long and rich history starting back in Saint-Imier, Switzerland. It was founded by Auguste Agassiz in 1832 and is owned by horology giants the Swatch Group. Repairs by Post are passionate about luxury watch brands and offer specialist repair through our convenient online watch repair service.


This brand’s history begins when Auguste Agassiz began working for a company who specialised in trading watch components. The company was taken over just a year later in 1933 where Auguste and his two partners make and sell pocket watches.


August Agassiz becomes the head of the company and enjoys great success selling watches in America, thanks to the fortuitousness of having family living there.


Auguste’s nephew, Ernest Francillon takes over the business slowly and renames it “Longines” thanks to the patch of land known as “Les Longines” which the factory was situated.  Longines have a great and rich history, we specialise in vintage watch repair, if you have a classic Longines watch send it for review and watch repair by our master horologists.


The Longine factory produces their first 20A movement in 1867, an award winning calibre which had an anchor escapement and a pendant winding and setting mechanism. The entire factory’s watches bear the Longines name on the dial. A winged hourglass is also engraved on the movements. The brand’s winged hourglass logo is the oldest registered trademark for a watchmaker.


Longines’ technical director Jacques David heads to America is 1976 and sparks the catalyst for the industrialisation of Swiss watches upon his return thanks to the report of his experiences at the United States for the Universal Exhibition.

Together, Francillon and David become pioneers in mechanised watch production. In 1878 the brand created the 20H calibre, a chronograph movement patened by Alfred Lugrin. This was the brand’s first precision piece, and an area the brand’s interest continued to grow over the years.


The first known advertisement for the brand can be seen in 1881 as a method to assist those in the horse racing industry looking to improve their performance. By 1886 the brand is supplying the majority of New York’s sporting officials.

After the brand received popularity in the sporting world, their next mission was to become famed for precision timing. In 1888 the brand created their first certified chronometer was the 21.59 calibre which was based on an 1878 model.

In 1889 Longines is associated with exploring for the first time, when it equips Prince Luigi Amedeo of Savoie, Duke of the Abruzzi, in his Arctic expedition.

In 1912 the brand creates their first electromechanical watches for sports timing. These watches use wires which when broken start and stop the watch.

The brand continues to develop their sports timing watches and develop their first 13.33Z wristwatch with a single push-piece. The watch had a 30 minute instantaneous counter and enjoyed accuracy within 1/5 of a second.

During 1916 the brand pushes the boundaries of creativity and manufacture timepieces with oval and rectangular shaped movements for their wristwatches.

They develop watches to be used by aviators and help time records set by these pioneers.

Longines and Navy officer Philip Van Horn Weems develop navigational devices together in 1927. These devices allow the user to synchronise the second hand with a GMT signal.


In 1931 a new instrument is created based on this design – the Lindbergh Hour Angle watch. This device helps aviators calculate longitude and define their geographical location. Eight years after Longines craft their navigational watches with Van Horn Weems, in 1935, a patent is finally filed.

In 1936 Longines produce their 13ZN calibre in various variations, with one or two push pieces and semi instantaneous 30 or 60 minute counter. This calibre has proven to be one of the most notable in the history of horology.

In 1939 the brand develops mechanical timekeeping equipment with or without a flyback hand that is accurate within 1/100 of a second.


The brand develops a new hand-wound mechanical movement with a chronograph function, the 30CH


Longines create their first quartz clock. This leads to developments in accuracy including a camera attached to a clock to record sports timings on film. In 1959 the brand develops watches especially for observatory competitions oscillating at a frequency of 36,000 vibrations per hour, for even greater accuracy. The 360 calibre sets new records for accuracy in the wristwatch category at the Neuchâtel Observatory.
