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.  The 7751 features a Moon Phase and Triple Date; 7753 features 9-6-3 Subdials with Date at 4:30 or 6:00. 

ETA  2894-2    ETA also produces this movement.  The 2894 is cutting edge, vibrating 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.  Tag-Heuer, Chopard, Omega, and Baume & Mercier, among others, use this movement.

Zenith El Primero    This is probably the most famous chrono 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 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 the Daytona in 2000.  At 44 Jewels with a vph of 28,800, this movement has already won praises for it's toughness and accuracy.  Elegant  three-column design with a phenomenal 72 hour power reserve. Now Rolex, like just a few other Houses, produces all its movements in-house.

Frederic Piguet 1185   At 21.600 vph, this 37 Jewel movement is used in Audemars Piguet, Blancpain, Cartier Pasha,  VC, and  Brequet, among others.  With its exquisite three-column design, it is a favorite of collectors, who have considered it the finest autochrono movement made.  Exceptionally thin at 5.2mm.

Omega 3313 Co-Axial  This is Omega's Showpiece movement, but now upgraded to include the Co-Axial Escapement (a large leap in mechanical technology). With a large power reserve of 55 hours, 3-column design, 37 Jewels, this movement is now state of the art (28,800vph).

Patek Philippe 5960  PP's first automatic chronograph movement (2006) is a 3-column design, vibrating at 28,800 vph with 40 Jewels.  Complete with a solid 18K rotor and a 55 hour reserve, this is the most exclusive autochrono movement made, and with the Rolex, available in no other watch.  Generally available on eBay for less than 80K in platinum case.

Breitling BO1 With 47 jewels and a remarkable 70-hour Power Reverve, the BO1 now joins this list.  A Jumping 30 minute totalizer at 3 and a flat Hirpin are among the highlights.   Available on a variety of  Breitling models.

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 by a variety of producers are now in the early stages of production.  See an article in Europa Star:  Mechanical Movements: the Race for Alternatives, or search La Joux-Perret; Sellita; Technotime.

CLONES AND ALTERNATIVES

The largest and the most ‘faithful’ supply of basic ETA-type movements, in all senses of the term, is provided by Sellita. Right after the announcement of the delivery stoppage of ETA kits, Sellita—which assembled and customized approximately 30 per cent of ETA ébauches for third parties—launched its own production of cloned calibres whose patents had expired but which formed the basis of ETA’s historical offer. These include the famous and indestructible ‘tractors’, namely the ETA 2824, 2834, 2836, and 2892 series, as well as the Valjoux 7750.
The production of the Sellita range, SW 200, SW 300, and SW 500 is estimated to be around 1 million pieces per year. The advantages of these movements are Sellita’s competiveness and the fact that they are perfectly compatible with the ETA movements, thus assuring global after-sales service. From Anchorage to Timbuktu, there will always be a watchmaker who has experience with ETA movements and who is therefore capable of repairing the Sellita clones.

Sellita SW500 (Valjoux 7750 clone):

Sellita’s latest creation, the SW500 Calibre meets the growing demand for Swiss automatic chronograph movements. An impressive combination of quality and absolute mastery of horological techniques, this movement offers the same high performance and level of reliability as an ETA 7750 movement.
Description   Automatic chronograph
SW500 13 ¼ ’’’ calibre
25 jewels
28,800 vib/h (4 Hz)

Diameter: 30.00 mm
Height: 7.90 mm
Hours, minutes, small seconds
Automatic ball-bearing winding-mechanism
60-second chronograph
30-minute and 12-hour counters
Date and day, corrector
Stop-second device

There are many more ETA movements that are relied upon, but Sellita is making good headway offering the most popular movement ebauches. Images in this post are of the SW300 and SW500. They have been decorated a bit, but when it comes down to it each brand will likely decorate movements how they want. Being able to buy a kit is really important given the price and flexibility of the brand to do what they like with it. Buying already make movements from ETA is going to be very expensive, and is going to require brands in many instances to take them apart, and then put them back together. While Sellita is the major hope now, I have a feeling others will step into place in the coming years. In short, when you see SW300 and SW500 movements as part of a watch spec, now you know what they are.

The 800-pound gorilla of Swiss movement production is ETA SA, part of the manufacturing arm of the Swatch Group. ETA supplies the vast majority of finished movements, parts and base calibres to the Swiss industry, as well as making movements for watch brands within the Swatch group (for example: Hamilton, Tissot, Rado – all use ETA movements, while Omega has used exclusively modified ETA calibres along with in-house designs). ETA has grown to its current position over many decades of consolidation and takeovers of various manufacturers, eventually being integrated into the SMH group (which became the Swatch Group in 1998) – but all that convoluted history will be saved for future blog post.

ETA makes basic calibres and Valjoux chronographs (i.e. the 7750), Nouvelle Lemania is integrated into Breguet and produces chronograph calibres (like the Omega 1861/1863 and base calibres for Patek Philippe and Breguet), Frederic Piguet makes complicated calibres for top-level watches, Nivarox makes specialized springs and metal alloys, and so on. Swatch and ETA dominates the Swiss industry – not only in complete movements, but also in the production of specialized items required by other manufactures. Up until present they have also been the largest producer of ebauches, which are unfinished base movement “kits” sent to a company for finishing and modification in-house.

When it comes to ETA calibres, an ETA movement is not simply one-size-fits-all. There are four standardized “grades” of movements available, each with different performance and some key differences in parts. Standard is the basic, least expensive level – they are undecorated and feature economy parts to keep the cost low. Standard is what you would find in an automatic Swatch. Elabore is the next step up, still without decoration but with some upgraded parts, and is adjusted in 3 positions to a slightly higher degree of accuracy. You will find Elabore in Hamiltons, and it is the least expensive grade of chronograph available. Top, or Top Soigne (top care) is the third grade – it is decorated with polished components and a combination of perlage and geneva striping (specific patterns and finishes are chosen by the purchasing brand) on the bridges, uses blued screws, has upgraded jewels and balance assemblies, and is adjusted in 5 positions to near-chronometer accuracy.

ETA’s dominance of the market. Selitta is one of the largest suppliers at the moment, having begun as an assembly centre for ETA before building complete calibres. Their movements are copies of ETA designs that have expired patents, but with some subtle differences in parts and finishing – ETA and Sellita parts are not interchangeable, despite their similarities in design.

Soprod is a smaller producer of complete movements, and generally produce higher-grade calibres that are well suited to midrange independent brands. They have proprietary designs finished to a high degree, something along the lines of an ETA Top Soigne. The also produce a range of quartz calibres. Like Sellita, they began as a facility dedicated to finishing and modifying ETA calibres (as well as building complication modules made to bolt onto existing calibres), but have recently begun producing their own designs.

Dubois-Depraz is a name that is often referenced within the industry, being one of the top manufacturers of complication modules (a module is a kit that attaches to an existing movement to add additional functions). A family-run business since 1901, they are based in the Vallee de Joux

The Swatch Group yesterday
Under the leadership of Nicolas G. Hayek (1928-2010), the Swatch Group achieved worldwide renown as the crown jewel of the watchmaking industry. In the early 1980s, Mr. Hayek led the firm’s recovery from a severe crisis. His decisive leadership was critical to the launch of the Swatch watch in 1983 and subsequently drove the continuous development and improvement of all Swatch Group brands. His innovative strategies also served as important models for the Swiss watchmaking industry as a whole and played a key role in the revival of the industry. The achievements of N.G. Hayek have been widely recognized in Switzerland and beyond, resulting in a number of notable awards, including that of Doctor honoris causa, awarded by the Universities of Neuchâtel and Bologna in 1998. In 2003, he was named Officier de la Légion d’Honneur de France. Nicolas G. Hayek was Chairman and Delegate of the Board of Directors of The Swatch Group Ltd from 1986 to 2010.

In 1998, SMH (Swiss Corporation for Microelectronics and Watchmaking Industries Ltd.), founded by Nicolas G. Hayek in 1983 through the merger Swiss watchmakers ASUAG and SSIH, was renamed The Swatch Group. At the time, both SSIH and ASUAG held a number of well-established Swiss watch brands. ASUAG had been founded in 1931, SSIH a year earlier through the amalgamation of Omega and Tissot. SSIH’s principal objective was to market quality Swiss watches. By taking over companies that produced high-quality movements and a number of lower-end watch brands, SSIH gradually managed to establish a strong position as a Swiss watch manufacturer. ASUAG’s mandate was to maintain, improve and develop the Swiss watch industry. ASUAG also expanded gradually through the purchase of companies that made movement-blanks and a number of finished watch manufacturers that were subsequently brought together under the subsidiary GWC General Watch Co. Ltd.

In the 1930s, both ASUAG and SSIH sought to combat the severe economic crisis and ensuing unemployment by means of complementary research and development programs in their respective companies. It proved difficult for both, however, to implement a common industrial policy for the subsidiaries concerned. Following repeated crises in the Swiss watch industry, by the 1970s both ASUAG and SSIH were once again in trouble. Foreign competition, in particular the Japanese watch industry, with its mass production of cheap new electronic products and new technology, was rapidly establishing a strong foothold in the market. Eventually, both ASUAG and SSIH faced liquidation, and foreign competitors were offering to buy prestigious brands such as Omega, Longines, Tissot, and others.
