When the time comes for your Longines Watch Service it can be difficult to know where to turn

Do you return your Longines to the jewellers where you bought it? Do you hand it over a shopping centre kiosk? What about the number of online 'specialists'?

Who can you trust to carryout your Longines Watch Service correctly and protect your watches value? Do you return your Omega to the jewellers where you bought it? Do you hand it over a shopping centre kiosk? What about the number of online 'specialists'?

What’s wrong with my Longines watch?

That Longines on your wrist is a marvel of human engineering, with up to and sometimes exceeding 60 meticulously manufactured parts working in unison to keep accurate time.

Not only is it working for you 24 hours a day, 7 days a week, 365 days a year, it also has to sustain the jolts and movement of day to day living which is no easy feat. Over time your Longines watch is going to need to be maintained by a professional watchmaker to restore it to optimum performance. Some of the most common faults your watch could be experiencing are;

Irritants in the Movement

Irritants in the Movement

The number one reason for your watch experiencing issues is a buildup of dirt and irritants inside the movement. The tolerance levels inside watch movements are so fine that any amount of dirt or dust can cause poor performance by becoming trapped between the parts. It is with this in mind that all watches should be serviced every 3-5 years to clean the movement completely and when having a battery replaced all seals and gaskets should be replaced to protect the movement from exposure to irritants. It is so important for a watchmaker’s workshop to be as clean and dust free as possible when working on your watch so always ask to see the workshop when having your watch repaired. If it doesn’t look like you could eat your dinner off the floor then it isn’t a suitable place for premium watch repairs to be carried out.


Problems with the Mainspring

The second most common problem that can affect your watches performance is an issue with the mainspring. The mainspring is your watches power source, which slowly unwinds releasing the right amount of energy to power the wheel train. It is the mainspring that is being wound when you turn the crown on a manual watch or when the oscillating weight in an automatic watch turns. If your crown is turning completely without any resistance this is most likely because your mainspring is broken and will need to be replaced. Without the mainspring performing at it’s optimal level your watches performance will suffer, so it is often replaced during repairs or services. You cannot however overwind a watch which is often what people believe to have happened when bringing in for repair.

Dry Oils and Lubricants

Dry oils and lubricants

Your watch has a number of moving parts all working together in unison. To stop each part wearing against each other specialist oil and lubricants are used to keep everything moving smoothly. These oils and lubricants only have a set shelf life and will dry up over time resulting in your watches parts grinding and wearing each other down. This causes dust and irritants to fill the movement and the level of accuracy to be diminished. Having your watch re-lubricated is very intricate work as there is a fine line between under and over oiling the movement and should always be carried out by an experienced watchmaker.

Moisture and Water damage

Moisture and Water damage

Nothing ruins a watch faster than water damage, causing rust throughout the movement. The only option available to repair if rust has set in is to replace the movement in it’s entirety. Although many watches are marketed as ‘water resistant’ this is only half true. The majority of watches are only splash proof and should never be submerged fully in water. Only specialist diving watches are designed to be worn under water. If in doubt you should always err on the side of caution and take your watch off if you plan on being anywhere near water as the damage to your water through water ingress could be substantial.

Magnetized movement

Magnetized movement

Just like other metals your watches movement can become magnetized when it comes into contact with certain levels of magnetic fields. These can be found near microwaves, large speakers or even the magnetic closure of purses and bags. A magnetized watch will run much faster than normal. Once magnetized you will have to take your watch into a professional watchmaker who will be able to check the movement and demagnetise using a special machine.

High Movement Consumption

High Movement Consumption

The older quartz movements (battery powered) become the higher their consumption can be which results in a new battery being needed more frequently. This can be due to dirt inside the movement, which is making the battery work harder to power the watch. It is often better value to replace the quartz movement in its entirety rather than service the watch as the replacement movement is cheaper than the value of the time it would take to strip and restore.

What is involved in an Longines Watch Service?

  • 1The watch is broken down and the movement is removed from the case. The bracelet, case, seals and movement are inspected thoroughly to diagnose any issues. We strip the whole movement and the case components.
  • 2Every part inside the watch is inspected for wear and anything showing the slightest sign of deterioration is removed and replaced with new parts from the manufacturer. Tolerances inside watches are so fine that even the smallest defect can affect performance.
  • 3Once inspected all parts are then put through our ultrasonic cleaner with specialist fluids, which removed old grease from the parts.
  • 4After it goes through the cleaning agent and three rinsing agents, it is put through a drying process resulting in a completely clean movement ready for re-assembly and lubricating.

  • 5We assemble the movement and fit the dial and hands assuring everything are aligned and then time test the watch to assure it is performing accurately.
  • 6We then move on to the case and bracelet (if the watch has one) which is cleaned and refurbished. We use various polishing, cutting and grinding wheels to remove any small dents, scratches and imperfections where possible, brining the watch as close to new condition as possible.
  • 7The case is reassembled so it is now a watertight empty case. We then pressure test it to the required bar to ensure there are no leaks.
  • 8Watch is reassembled and time tested for the second time and placed on test for 2-3 days on our workshop simulator which slowly moves the watch round in different positions. This allows us to monitor the watches performance and see if any further adjustments are required.

Your Longines watch must always be diagnostically inspected first to produce an accurate repair quotation, this allows the watchmaker to find out exactly what issues need addressed and price any parts accordingly.

However most repairs are covered in a full Longines watch service price which varies depending on model. The price is made up of the master watchmakers time in servicing the watch (which can take up to 4 hours) and the cost of any parts required to restore performance. If you are being offered a service for cheaper than these costs it would be advisable to proceed with caution as it may be generic parts that are being used in your repair resulting in your watch losing its worth and running into similar problems soon after. The old adage holds true for luxury watch ownership, buy cheap, buy twice. Having your watch maintained by an accredited service centre will ensure your Longines watch lasts long into the future and retains its value.

How long do Longines repairs take?

Time for parts to arrive from manufacturer (can’t keep stock as too vast) and watchmakers time (can only do 2 services a day) Master watchmakers are in high demand with only a select few across the U.K who are trained and accredited to work on Longines watches.

I gave Jon Vincent a vintage Longines watch that had belonged to my Father. It had been lying in a drawer and had given up the ghost many years ago. Upon examination, the guys at Jon Vincent discovered that the old battery had leaked and caused extensive corrosion. Undaunted, they searched for a replacement part and eventually sourced one in the USA. Yesterday, the watch was returned to me in full working order, fully serviced and fitted with a beautiful crocodile leather strap. I would like to thank everyone at Jon Vincent for their sterling work and personal attention. I have no hesitation whatsoever in recommending Jon Vincent Watchmakers to anyone looking for a first class service with a personal touch.

The History of Longines

A Brief History of Longines

Associated with the pioneering of aviation, and the equestrian lifestyle, Longines offers supreme Swiss engineering and tasteful designs. Throughout its 185 years of producing finely crafted, remarkably precise timepieces, Longines has established itself as one of the most distinguished watchmaking brands in the world. The label is especially known for engineering top-quality products with a unique tendency of reworking old designs, bringing its heritage back to life.

Today Longines is an honourable member of the Swatch Group, which owns Swiss watchmaking powerhouses such as Omega, Tissot, Rado, and Breguet. Prior to becoming a subsidiary of the Group in 1983, like most Swiss watchmaking companies, it was a family-owned business, passed on through generations.

Longines was established by Auguste Agassiz and his two partners in 1832 in Saint Imier, more specifically in Es Longines, after which the brand bears its name. By 1846, Agassiz’s talent and imagination naturally positioned him as the de facto head of the company. Thanks to his contacts in the United States, Agassiz was able to successfully distribute Longines watches on the other side of the Atlantic. This was crucial to the company’s early success, alongside with the efforts of Ernest Francillon – Agassiz’s nephew. Francillon was a qualified economist whose thorough expertise in the field enabled him to gradually take over the firm from his uncle.

The factory premises in Saint- Imier, where the headquarters are located to this day, was officially inaugurated by Francillon in 1867. Also that year, the company produced its first movement – the 20A. This truly remarkable piece of engineering, featured a pendant winding and a settling mechanism. It was highly regarded by watchmakers alike, and won a prestigious award at the Universal Exhibition in Paris in 1867. However, the company’s most significant innovation was soon to follow. When the firm’s technical director crossed the Atlantic on a business trip to Philadelphia, he envisaged new production possibilities. These where hitherto unexplored in Switzerland, which still relied on the time-consuming system of établissage. Thus, Longines became credited with catalysing the industrialisation of Swiss watchmaking.

In 1888, after establishing a new system of production largely dependant on machine tools, Longines became involved in high-precision timekeeping, and began producing movements for a certified chronometer – the 21.59 calibre. This was the beginning of the company’s path to specialising in extremely precise and reliable time measuring pieces, soon to be used in aviation, and sports events.

The early success and wide renown of Longines made it susceptible to frequent imitations. In order to prevent this, in 1880 Francillon filed the brand name with the Federal Office of Intellectual Property, and registered the logo in 1889. Regarded as the sign of authenticity, all new watches produced by the company featured the winged hourglass logo on the dial, as well as on all movements. With this installed, Longines famously became the world’s first watchmaking brand to adopt a trademark registered with the WIPO (World Intellectual Property Organisation).

Continuing its tradition of horological innovation, 1919 was a significant year for Longines. During that year, the brand entered a close-tie relationship with aviation. It became the official supplier for the International Aeronautical Federation, and developed highly accurate and reliable navigation instruments for the use of aviation pioneers.

The aviation connection tightened in 1931, when Charles A Lindbergh – the American pilot and international celebrity designed a navigational instrument which Longines brought to life. The custom-made, Lindergergh Hour Angle watch was an advanced timepiece, largely based on the preceding Weems System of Navigation which helped aviators calculate their geographical location.

Aside from having a strong association with aviation, the company has also established a firm connection with horse racing, which has grown in prominence over the recent decades. Thanks to its accurate time measuring and elegant aesthetics, Longines became the perfect fit for the equestrian lifestyle. To publicly seal the collaboration, in 2013 the company became the official parter of the prestigious Ascot racecourse.

The Longines watch collection consists of a diverse range of timepieces for both men and women with a taste for stylish yet understated watches. In 1954 the company launched what turned out to be its most popular watch family – the Conquest line. The Conquest, being the first of Longines models, is commonly regarded as the very embodiment of sports inspired elegance. It is remarkably versatile, offering a blend of style and practicality. In addition, it is water resistant to 300m. 

Longines Conquest

In 1957, following the launch of Conquest, the elegant Flagship collection was introduced. It is characterised by traditional craftsmanship embellished by a sophisticated, yet functional case. It comes in a variety of models, for both men and women, who appreciate style and quality.

Longines Flagship

In 1979 Longines produced extremely slender watches that were only 1.98 mm thick. Building on this heritage, in 1982 Longines launched La Grande Classique is the extremely elegant Grande Classique, a true horological masterpiece, remarkable for its slimness, and effortlessly chic appearances. An enduring classic, it is one of the bran’s most popular pieces.

Another successful line of Longines watches is the Master collection. It is instantly recognisable for its silver dial, large Arabic numerals, and a leather strap. It is a functional, sophisticated, and distinctively comfortable watch designed for a modern man. One who   appreciates style as well as quality.

Longines master Amongst the most popular ladies’ watches is the highly esteemed Dolcevita line. It is synonymous with subtle style and sophisticated elegance. The iconic DolceVita remains one of the most popular ladies watches. Instantly recognisable by its original rectangular case, it is said to represent the decadence of Italian lifestyle.

Longines DolceVita

Appreciated by watch enthusiasts across the globe, Longines offers a range of functional and beautiful timepieces suitable for those with most refined taste. Its impressive history, and honourable association with aviation and horse racing, makes it a truly prestigious brand, offering comfort as well as classic elegance.
