Two years later in 1894 they also registered the name ‘Omega’ and applied it to a new range of high quality lever movement pocket watches they had developed using cutting edge manufacturing technology. So successful were the new Omega watches that the Brandt brothers decided to form a new company alongside Louis Brandt & Frere and move the production of some of their other watches to it to in order to make extra room in their Bienne factory to allow increased production of Omega watches. On the 5th August 1895 the new company ‘Société d’Horlogerie La Générale’ was formed in La Chaux de-Fonds as a joint venture the directors being Louis Paul Brandt, Edouard Boillat of the ébauche company Ed. Boillat & Cie and initially Louis Courvoisier though he resigned in 1897. 1897 was also the year that the company was additionally registered under its English name, ‘General Watch Co’, and moved its registered office to Bienne. Following the founding of La Générale production of most of Louis Brandt & Frere’s lower quality cylinder watches were moved there including the brands Helvetia, Paradox, Jura, Gurzelen and Cosmopolite. La Générale watches were often marked on the dial and case ‘La Générale, Successeur de Louis Brandt & Frere’ and it looks as if the Brandts were using the pull of their famous name to move the customers of their non-Omega watches over to La Générale allowing them to concentrate on Omega. Indeed, in 1903 they renamed their company from Louis Brandt & Frere to ‘La Société Anonyme Louis Brandt & Frere (Omega Watch Co)’. Also in 1903 first Louis Paul and then César Brandt died and, though Adrien Brandt replaced them as a director of La Générale for several years, in 1911 the Omega Watch Co finally withdrew from La Générale and those brand names in use by them that were still registered under Omega were officially transferred. Following the withdrawl of Omega, Edouard Boillat transferred the rest of the company Ed. Boillat & Cie to the control of La Générale including his factory at Reconvilier. In the years since 1895 La Générale had begun to make better quality lever movement watches, sold mainly under the Helvetia name, and in 1906 they built a new factory in Bienne with offices and workrooms for 104 workers. Here they developed a 13 ligne movement that was used in their first wristwatches around 1909 and also registered brand names in their own right such as General in 1902, Adonis in 1905 and Orta in 1911. The start of the first world war in 1914 signalled some major changes to the Swiss watch industry. The need to be able to tell the time quickly and easily in the trenches without fumbling for a pocket watch meant that wristwatch use and production rose rapidly and the poor conditions that a watch was liable to meet also meant that water and moisture resistance became more important. La Générale seems to have started to specialise in watches with this type of protection around this time. They had actually developed a pocket watch with water resistant properties by 1913 and during the war a large percentage of their wristwatches were of the hunter or half hunter types that included a hinged lid to protect the face of the watch from damage. They also provided adapted pocket watches for use in German aircraft cockpits and sold watches under the brand names Kitchener and Les Poilus (a nickname for French troops) in allied countries. La Générale finished the first world war in a strong position. They valued their company at 1,000,000 Swiss Francs in 1920 more than double the pre-war value. During the 1920s they continued their specialism into protected watches; a report on the 1920 Swiss Watch fair mentions “Among other original creations we notice the miner's watch, of an exceptionally robust construction and completely impermeable.” By about 1924 they had also started to produce watches with shock protection, which was very unusual at the time and initially appears to have been a version of the Depollier/Brun shock protection system patented in 1921. This was the time La Générale also began to use the English version of their company name, General Watch Co, prominently in their advertising and push the brand name Helvetia to the fore. Though they did occasionally manufacture watches under some of their other brand names such as General or Post almost all the watches they produced from the late 1920s bear the name Helvetia. These developments came together in 1929 with the production of the Helvetia waterproof and shock protected watch. This watch combined the General Watch Co’s own newly patented shock protection system in a brand new 10.5 ligne movement, the calibre 81, and a water protected silver case with gaskets in the stem and case back. To accompany the new watch a new Helvetia logo was added to the dial though it wasn’t officially registered until 1931, before this a flowing script had been used for Helvetia watches up to about 1908 and plain block capitals from then. Although continuing to develop their Helvetia water and shock protected watches throughout the 1930s; for instance they patented a waterproof crystal fitting in 1931 and an anti-shock movement mounting in 1933 with a centre sweep seconds version being introduced in 1935, this was by no means the only string to their bow. In 1932 they registered a design for a watch with a date window at 12 o’clock and this resulted in the world’s first ‘Big Date’ watch using the Helvetia calibre 75 movement, they also patented a ’stop seconds’ chronograph in 1940 but perhaps the reason that the Helvetia brand is most widely known today is for their pilots’ watches. The General Watch Co first introduced their version of the ‘1928 pattern’ pilots’ watch in 1932 and introduced their famous spinning propeller logo in January 1933 making thousands of these watches up to 1945. The inter war years were not a happy time for the Swiss watch industry however with a host of small companies in competition with each other in a smaller market and price rises and crashes were common. To try to stabilise the market the Swiss government and banks encouraged, and supported with loans, the formation of ‘Allgemeine Schweizerische Uhrenindustrie AG’ (AUSAG) a group of watch movement and component manufactures that would work together in concert to keep prices and production stable and prevent over production and price fluctuation. Another major group of watchmaking companies was also formed at this time; 'Société Suisse pour l'Industrie Horlogère' (SSIH) was created by Omega and Tissot with an agreement not to compete in the same market segment. The General Watch Co’s innovations during this time helped them to weather this storm without becoming a part of one of these organisations, and their products remained in demand. Though, as mentioned, they tended to brand their own watches as Helvetia their innovative watches and movements were often sold to other manufacturers and distributers and bear a variety of these companies’ names. There are Helvetia waterproof watches branded Aero, Aeroplane, Huber and Abercrombie & Fitch; big date watches branded Ditis, Mimo, Girard Perregaux and Angora; pilots’ watches branded Aero, Helbros, Huber and Savoy and the Helvetia calibre 81 and 82, calibre 75 rectangular movement and calibre 32 pocket watch movement were also widely used by other firms. I’m discovering General Watch Co. movements in watches from other watch suppliers all the time. The second world war was another time of expansion for the company. They supplied pocket watches to the British and the German armies and wristwatches to the German and, at the end of the war, US armies, as well as specialist wrist timers to the Royal Navy. By the late 1940s, as at the end of the first world war, the General Watch Co’s value had doubled from a low of 350,000 Swiss Francs in 1938 to 700,000 by 1948. It was also in 1948 that they again decide to change their name this time to ‘Montres Helvetia Société d'Horlogerie La Générale’ and from this date onwards they are usually referred to as Montres Helvetia S.A. or Helvetia Watch Cy. Following the war Helvetia carried on making military style watches as the demand from ex-servicemen remained high but in the late 1940s they turned some of their capacity to producing some high quality, and large for the time, wristwatches including solid gold wrist examples something they had not done before. During the 1950s they again became quite innovative with some interesting dial and case designs and began to develop their own automatic movements, they even brought back their pilots watch for a short time during the mid 1950s. Their Registered Office moved in 1954 to their Reconvilier factory and the smaller Bienne site probably closed at this time. The 1960s were the beginning of another difficult time for the Swiss watch industry with cheaper Japanese imports starting to bite into their market. In an attempt to modernise a new Helvetia logo was adopted in 1963 and adapted slightly in 1965, model names were also added from this time such as Waterstar and Cosmotimer. Despite this Helvetia’s watches, while still high quality, were not very different to any of the other Swiss manufacturers of the 1960s and they too began to struggle. Eventually in 1968 Helvetia became one of the founding members of the Société des Garde-Temps S.A. or SGT alongside Avia, Degoumois & Co., Silvana, Eugene Vuilleumier, William Mathez and Fleurier. SGT was formed in order to allow the member companies to reduce costs by pooling administrative, research and design functions, rationalising factory space and compete alongside larger competitors with their increased buying power. Part of this rationalisation involved the move of the Silvana watch company’s offices from Tramelan to the Avia company site in Neuchâtel in 1971, and indeed in 1972 Avia actually changed its name to Avia & Silvana S.A. This move made room for the Helvetia management and administration to move to Tramelan and take over the Silvana factory though they also retained their factory at Reconvilier. Though Helvetia kept its factory it seems that their in house movement capability was a casualty as from this time Helvetia watches are mostly fitted with adapted ETA movements... RECOMMENDATIONS All Antique watches are mechanical. Many repairs will not be cheap, as most likely they will require replacement of non-standard parts (unlike most late model watches). Antique watches should not be beaten or dropped - because repairs may be expensive. Antique watches are generally NOT waterproof. This is because waterproofing was not in general production until the middle of the 20th century for most watches. Therefore you should protect your antique watch from exposure to moisture. If your watch becomes wet it should be dried off quickly. Carefully open all covers and use a hair drier to blow dry the movement, dial, covers, crown. This will reduce the amount of rust. If your watch becomes wet with any kind of salt water you should immediately immerse or spray your watch with fresh (no-salt) water to remove all the salt from the works before drying the watch completely. Any salt left in the watch will combine with moisture in the air to rust metal components of the movement, case etc. Winding any mechanical watch tight may break the mainspring. If you can avoid it do not wind the watch hard. When adjusting the hands of your watch, move them in a clockwise direction only. Counter-clockwise adjustments may damage the movement. It is desirable to adjust the hands of your watch at the same time every day. An automatic or self-winding watch should be worn for at least 8 hours a day. It is a mechanical watch in which the mainspring is wound automatically as a result of natural motion of the wearer's arm, to provide energy to run the watch, making manual winding unnecessary. If you must adjust counter-clockwise make it for small adjustments only (i.e. for minutes, NOT hours). Be careful and gentle when adjusting the movement speed (faster or slower). Don't make sharp movements, and don't touch other components in the movement especially the pendulum mechanism. Every 2-3 years it is necessary to service and oil vintage watches. If the course of your watches is worsening and the accuracy of the reduction in the duration of the clock (autonomy) from one fully wound spring - it need a service. IF the watch is dirty - allow the watch to run down, don't wind it again until you have it serviced by a qualified watch repair expert. Dust will absorb and remove important lubricants and cause the movement pieces to wear down. To clean the case, dial and crystal you should use a cloth that does NOT leave fibers as these may get caught up in the movement. Check with your Watch repair expert to get an appropriate cloth. Keep your antiques watch away from magnets. Strong magnetic fields may affect the accuracy of your watch since some vintage watches were made with iron based components in the movement. Most Cases and Covers are fine components and will not handle abuse well. The watch should not be shaken, beaten, or stressed. Antique watches generally experience an error of up to 5-7 minutes a day. Any accuracy of +- 5 minutes is very good. Mechanical watch is not recommended to use for engage in extreme sports, and expose them to excessive vibration loads. Recoil force, which take on the clock, affect their reliability and precision. No matter how perfect was not anti-shock mechanism, there is always the chance of excessive load that details of the mechanism can not survive. Watch with calendar. It is not recommended to adjust, the date between 20.00 and 06.00, because at this time involved a mechanism for automatic adjustment date. Translation pointers calendars manually in this position arrows may damage the mechanism. Date changes should be made, relegating pre-clockwise to lower sector of the dial (for example, to position 6 (18.00) hours). Chronograph watches. In most cases, these watches contain the "start/stop" button and "reset" button. It is strongly recommended not to press the "reset" if the chronograph is running. Before you use the "Reset" button need to stop the chronograph by button "start/stop". Using the "reset" when running chronograph can damage the mechanism of most models of watches.
