TwoTone Posted August 7, 2006 Report Share Posted August 7, 2006 Found this while surfing and thought I'd post it! TT ___________________________________________________________________________ A Brief Guide to Swiss Automatic Chronograph Movements There are literally 100's of various chronograph movements in play today. Many are less expensive Asian-made copies of Swiss Movements which will not be discussed. Rather, only Swiss-Made movements will be the main concern here. First of all, you do not need a "name" watch to get a very good timepiece. Many obscure manufacturers use the exact same movements as do the Big Boys. The only difference may be of refinement--the higher-end the watch the more the manufacturer may refine, polish and decorate the movement. Valjoux 7750 This is by far the most common Swiss Chronograph movement in production today. An integrated--designed to be a chronograph--25 Jewel workhorse, this is a highly durable, proven movement. Franck Muller uses it on occasion, as well as IWC, Baume&Mercier, Cartier, etc. An ETA (the largest Swiss movement manufacturer) product, it vibrates at 28,800 vph and is available in many configurations. It is non-modular--it was purposely designed as a chronograph. ETA 2894 ETA also produces these movements (the 4 is the latest). The 2894 is cutting edge, vibrating also at 28,800 vph with 37 Jewels. This higher jewel count is mandated because this is a Modular Movement--a piggyback chronograph module is positioned on top of the 28 series movement, itself with 21 Jewels. A remarkable 12.25 ligne in width. These movements are showing up in more and more chronographs. Also available in a variety of configurations. Zenith El Primero This is probably the most famous movement of all time. Zenith originated it around 1963-4, and it is, with minor improvements, still in production today. It is an integrated 31-Jewel wonder vibrating at 36.000 vph--the world's fastest mechanical chronograph. Rolex used this movement in the Daytona until 2000, when it premiered it's own movement. Also used in the Tag Heuer Calibre 36, Panerai, Roth, Ebel, etc. If a watch other than Zenith contains the El Primero, it will certainly be advertised as such. Lemania 1350 Ebel is the prime user of this 30 Jewel movement vibrating at 28,800 vph. Breguet uses a customized version of this in their Type XX. A very tough movement with a reputation for durability and lack of variance. Lemania also makes the 5100, a movement used by Sinn and Tutima. Rolex 4130 This brand-new Rolex Chronograph movement replaced the El Primero in 2000. At 44 Jewels with a vph of 28,800, this movement is still in it's infancy--however, early reports have been promising. Frederic Piguet 1185 Though this it the slowest movement here, at 21.600 vph, this 37 Jewel movement is only used in higher-end brands. A very thin, exquisite movement used in Audemars and Blancpain, among others. Three-column design, a favorite of collectors. Omega 3313 Co-Axial This is Omega's Showpiece movement, originally based on the Piguet 1185. It had a rocky start, but Omega appears to have redeemed itself. With a Huge power reserve of 55 hours, 3-column design, 37 Jewels, this movement is now state of the art (28,800vph). As of today, Swatch Group of Switzerland owns ETA, Lemania, Valjoux, and F. Piguet, giving it a stranglehold on the Swiss Watch Industry. It will be interesting; new movements are being created as we speak. 1 Link to comment Share on other sites More sharing options...
MimiSars Posted June 15, 2008 Report Share Posted June 15, 2008 (edited) Hi Ive got a question. Im looking to buy a Breitling Chronomat Evolution and I noticed that there are two different movements. New Asia Valjoux 7750 and Swiss 7750. What exactly are the differences between the two? Id figure that the New Asia would be better since it says "Valjoux" and thats what the real Brietling has but at the same time the real one is a Swiss. I know that Asian movements on other watches generally are cheaper, but I have no clue why. What are the differences between New Asia Valjoux 7750 and Swiss 7750?

EuroTimez Posted July 31, 2008 Report Share Posted July 31, 2008 Hi Mimimars, For starters, the SWISS ETA 7750 (also named SWISS ETA VALJOUX 7750) is what the original breitling is based on... What do I mean when I say "based" on... I mean that they (breitling) buy their movements in from ETA (they don't make it themselves), then what they do (just like tag-heuer,omega, tudor, and many other swiss brands) they either finish the movement --engrave it, decorate it etc, and/or they swap some parts of the ETA movement with their higher quality parts. But the "base" is still the same. So if you have the dough, go for Swiss 7750, it is the top of the top... Downside it is very expensive and hardly available... I don't have them. The Asian 7750-2 (you got generally 2 versions that are mainly used, A7750-1 (21.6k bph) and A7750-2 (28.8k bph) ) it is generally a good movement just beware that it is best when QC because most of the times the problems show at the beginning, so testing all functions prior to shipping is a big big plus as alot of members received DOA (dead on arrival) and that is just no fun... A7750-2 is at a much lower price and it comes close to the SWISS 7750 (as it is a copy of the ETA SWISS 7750) only needs some servicing then according to The Zigmeister (highly respected Watchsmith here on the forum and out of the forum ---because he's soooo good in what he does) it is just as good as a Swiss ETA 7750. Or what you can also do is, buy your rep readily available with A7750-2 (new asia 7750 it is also called) and then buy elsewhere a genuine Swiss ETA 7750 and swap it prices are around 400-600 usd for movement ONLY. TAKASHI (great guy, find him on RWI or here on RWG) made a guide on RWI (another great rep forum, like a daugher/sister forum of this one) how to swap it ---which I recommend you don't do if your a newbie --- I can't do it either ---, but use that guide for your watchmaker). Hope this helps... If you need help getting you an fully inspected EVO, you can always drop me a line. Link to comment Share on other sites More sharing options...

outfiliVelf Posted June 13, 2011 Report Share Posted June 13, 2011 Что мешает вам стать богатым и успешным уже сейчас, просто подняться с дивана и начать что-то делать хотя бы? А ещё лучше будет, если вы будете делать то, что нужно и по хорошо продуманному плану! Почему вы не верите в себя и решили что всё на свете не для вас??? Отговорки вроде: «я страшно устаю», «я из бедной семьи», «у меня нет образования», «я- домохозяйка», «ничего не получится, я уже что-то пробовал…» - не принимаются!!! Обрести уверенность в своих силах и желание изменить свою жизнь к лучшему вам помогут следующие семь ключевых убеждений, которые присущи образу мыслей самых богатых людей мира… повторяйте их вслух и про себя, утром по пробуждении, днём на работе, ночью в постели, главное – ежедневно и с полным чувством в своей правоте! Через месяц вы почувствуете себя увереннее, через два – у вас появится желание жить иначе, через пол года вы составите план действий и начнёте работать на себя, откроете свой собственный бизнес! Всего выше сказанного вполне достаточно чтобы уже захотеть сделать этот первый маленький шажок к успеху: сесть и прочитать то, что стоит так дорого и преподносится вам здесь так дёшево – даром! Итак, семь убеждений миллионеров, вот они: 1) Верь в себя и свой успех! (Вера в свои силы и упорный труд - города берут. Ваш случай не исключение.) 2) Всё что с тобой было, происходит сейчас и будет завтра – плоды твоих собственных мыслей, решений, действий (осознанных и нет). Помни бо этом и следи за собой: исправляй прошлые ошибки, думай о том, какое хочешь получить «завтра» уже сегодня. 3) Всё чего вы желаете – достижимо. Есть миллион способов получения желаемого. Определите те, что подходят вам, составьте план действий и начните работать. 4) Неудачи других – не аргумент для тебя! Боритесь за осуществление своей мечты, будьте гибким и пластичным на пути к успеху, не сдавайтесь! 5) Твои неудачи – это залог, фундамент будущего успеха! Неудачи – это жизненный урок, очень ценный и нужный. Воспринимайте их так и они принесут вам успех очень скоро, так скоро как вы примите их и простите себя, извлечёте ценный опыт и вновь примитесь за дело. 6) Нельзя предавать свои мечты никогда! Ни на миг! Не позволяйте себе терять веру: не люди, не обстоятельства не должны влиять на вашу убежденность в необходимости осуществления того, что вы задумали. 7) Жить надо ради счастливых перспектив и достижений, а не избегая бед. Не концентрируйтесь на негативе, думайте только о светлом, счастливом будущем для себя и своих близких, делайте всё для этого и будьте счастливы!
