Quality Swiss
watch repair
since 1993

We also undertake case and bracelet refinishing to Longines factory specification in our dedicated polishing department.

It is recommended by Longines that their quartz watches receive a battery service every 2 years and all watches receive a complete service every 4 to 6 years. However, if the watch is suitable for swimming and diving and is used in water they also recommend the water resistance of the watch is tested on an annual basis.

A brief history of Longines.

The main servicing procedure

  • A Complete Service involves the watchmaker checking the watch’s functions, diagnosing the cause of any faults.
  • The complete dismantling of the movement with the correction of any faults and replacement of any damaged / worn parts.
  • All parts are then cleaned in a series of ultrasonic chemical baths which removes all the old oil, grease and dirt.
  • While the movement is being cleaned the case will be completely broken down (case back, bezel, crystal,pushers etc. removed) and, having removed all the seals and gaskets, refinished and cleaned in large ultrasonic tanks.
  • Once the case is clean it is reassembled with new seals and gaskets, which are lubricated as required with special greases. The case is now ready to receive the cleaned movement.
  • The cleaned movement and pristine components are systematically reassembled and lubricated using up to 8 different fine synthetic oils and greases, before having the dial and hands refitted.
  • The watchmaker will now reset the clean movement with the dial and hands mounted into the watch case ensuring there are no hairs or dust in the case and recheck the watch regulation on the timing machine.
  • Once the case is closed the watch is then tested for water resistance and the final aesthetic, timekeeping and power reserve checks are made to ensure the watch is performing correctly.

Battery service

  • The watch is opened and electronic components checked using specific testing equipment.
  • Replacement of the battery and gaskets as appropriate to the watch model.
  • Tested for water resistance. Final aesthetic and timekeeping checks to ensure the watch is performing correctly.


We will rectify any defects arising from any service provided by us provided you report such defects to us as soon as reasonably possible. The warranty period for partial repairs and full service is 24 months. We reserve the right to invalidate the warranty if repairs are performed by persons not authorised by us to take such action. Provision of the warranty will be free of charge. We will decide in our absolute discretion whether provision of the warranty will be in the form of a repair or the replacement of a part of the watch. Evidence of purchase must be provided and any replaced parts pass into our ownership. Limit of warranty. The provision of services under warranty neither extends the terms of the warrant nor sets in motion a new warranty period.

The provisions of this warranty do not extend to defects caused by general wear and tear, accident, negligence or lack of care; or component parts that are expected to require periodic replacement.


I wanted to say how pleased I am, my Ball watch looks nothing short of  stunning. You were a joy to deal with, it was seamless. Not only that, but you achieved all this in a far shorter time than your original estimate. I would recommend you and your Company without hesitation!

Thank you to the team for the servicing and refurbishing of my fathers' Omega watch. The accuracy is well within original factory tolerance and refurbishment makes it look as good as new. Thank you also for the tour of your workshops when I collected my watch.

Brief history of Longines Watch Service

Based in Saint-Imier in the heart of the Jura mountains Longines has been producing timepieces since 1832. In 1832, Longines founder Auguste Agassiz and two partners, Henri Raiguel and Florian Morel (his brothers in law) launched their own comptoir in the town of Saint-Imier. Auguste Agassiz had important business connections in America, which soon became a large market for the assembled watches of RaiguelJeune& Cie.

Eventually both Raiguel and Morel left or retired, and Agassiz took control of the company, however, he was forced into early retirement by poor health in 1850. This brought in his nephew, Ernest Francillon into the business in 1852 and Auguste Agassiz remained his business partner until his death in 1877. In 1866, Ernest Francillon purchased land south of Saint-Imier and built a factory in an area known as les longines, the long meadows. In 1867 that Ernest Francillon brought in Jaques David to help implement the industrialisation which Ernest Francillon was developing and Jaques David was put in charge of the operation of the factory.

1867 was also the year RaiguelJeune& Cie. changed name to Longines, named after those long meadows where the new factory was located. In 1876, Ernest Francillon sent a delegation headed by Jaques David to the World’s Fair in Philadelphia, there, he saw the industrialised processes being used by the American watchmaking industry and he brought home many ideas which were implemented in the new factory. By 1880, Longines had created enough production capacity to move away from its traditional movement suppliers and create all their movements in-house.

The Longines winged hourglass logo has been in use since 1867 and the logo we see today was registered in 1893. This makes Longines the oldest brand name registered with the World Intellectual Property Organization still in use today. In 1971, Longines was purchased by the ASUAG group, and the subsequent merger of ASUAG with SSIH became part of SMH which in turn bacame the Swatch Group.These days, Longines is known for being the official timer of numerous equestrian, horse racing, tennis, and gymnastics events. These include being the official timer at Royal Ascot and the at the French Open at Roland Garros.
