Especially in recent years, Omega was one of the most innovative and respected manufacturers in the industry. Looking at the current caliber lineup of the Swiss watch brand, it is clear that Omega is mainly concerned with technical solutions with substantial added value for the user day. From the co-axial inhibition to themagnetic protection of more than 15,000 Gauss , of pure in-house works and those originating from partnerships-the works built in Omega watches are among the best that the market has to offer.
1. Omega 2500 Co-Axial – The First Omega Factory With Co-Axial Inhibition
The Omega 2500 automatic movement was introduced in 1999 and is the first series-produced movement that draws on George Daniels’ invention of Co-Axial escapement. The basic idea of the Co-Axial Inhibition is to combine the two traditional inhibitor types, the Chronometer Inhibition and the Anchor Inhibitor, while gaining benefits in terms of maintenance frequency without sacrificing a reduced gait. Perhaps it was a little too optimistic at first, when it was assumed that wristwatches would be completely lubrication-free by means of co-axial inhibition. Even if it is not yet possible to do without waiting, adaptations in the 2nd and 3rd generation as well as a special lubricating oil have led to a new level of serviceability. The 2500 is the first co-axial plant to become an icon. It is therefore not surprising that the caliber still bears the same name even after repeated iterative improvements.
2. Omega 8500 Master-Co-Axial – The High-Tech Reference Of The Watch Industry
As in any industry, benchmarking is also practiced among luxury watch manufacturers. We are looking for generally accepted examples from the recent past, which have perfectly adapted the current state of technology or redefined it at all. The Omega 8500 is such an industry reference, similar to the Rolex 3135 for many years.
Allegedly, a three-digit million figure flowed into the over a decade-lasting development of the Omega 8500. The plant runs so accurately that the monthly gait deviation is already over a period of several years in the low seconds range.Using non-magnetic materials, the latest 8500 generation Master Co-Axial achieves a magnetic resistance of over 15,000 Gauss. But it is not only that, it is one of the most modern and sophisticated calibers in the world. It hardly shows a position-dependent amplitude drop so that it does not matter – as with a tourbillon – whether the clock performs in horizontal or vertical position. The two spring housings allow a 60-hour reserve, and it is important to emphasize that the accuracy of the gait is hardly noticeable even at low tension. This is especially handy for people who like to spend their time on the Friday evening.
The Omega 8501 is also identical to the 8500, but has a rotor and a bridge of gold (the 8500 consists of a bridge and a rotor as well as a rhodium-plated stainless steel plate). The slightly modified 8602 also has a weekday display in the style of the Rolex-DayDate in addition to the date display of the 8500.
3. Omega 8400 Master Co-Axial – The “Stripped Down” 8500
Like the Omega 8500, the 8400 is also equipped with a master co-axial escapement. In contrast to the famous sisters’ caliber, however, it does not have a date function. Since the 8500 is not only for a specific caliber variant but for a whole caliber series, the term is often used synonymously for all the 8XXX family.Thus occasionally the 8400 is also called 8500. The same is true for other versions such as the 8401/8501 (variant with red gold rotor), 8508, 8520 (smaller variant) or 8605. The Omega 8400 is installed in the retro variant of the Omega Seamaster Diver 300 and the Omega Seamaster Specter .
Installed in: Omega Seamaster Diver 300 , Omega Seamaster Specter LE
4. Omega 8511 Master Co-Axial – The Modern Manual Hoist
The Omega 8511 handrail combines the technicality of the 8500 with the aesthetics of a finely finished movement in the tradition of Patek Philippe or Vacheron Constantin. The caliber is installed in the premium dress watch Omega De Ville Trésor and is also visible in the unopened state by a sapphire crystal case back. In the eye, next to the exciting cut above all, the balance bridge of gold, which is also known from the 8500-modification 8501. The functionalism of an automatic lift was intentionally dispensed with in the 8511, in order to save on the same height compared to the 8500 and to allow an unsealed view of the caliber.Like the Omega 8500 and 8400, the hand-held version 8511 also has a fast-setting of the hour at medium position, which is particularly useful when changing the time zone.
5. Omega 1861 – Clock Of The Speedmaster Professinal “Moonwatch”
The current chronograph caliber 1861 with manual lift has undergone some significant changes in the course of its long history of origin, but it is still largely based on the original design in the form of the caliber 321 with column wheel.This was, in the original Moonwatch Ref. 105.012 installed , in 1969 to the very first clockwork, which landed on the wrist of a man on the moon. Contrary to the legendary caliber 321, today’s 1861 is no longer equipped with a column wheel.Instead, it switches by means of a slot switch, which does not however abort the icon status of the Moonwatch caliber.
The Omega 1866 is a 1861, which was extended by the function of a moon phase display. In addition, the date is not displayed digitally using a turntable, but in analog form with the help of a pointer. Like the 1861, the 1866 is also raised by hand.
Installed in: Omega Speedmaster Professional (version with Hesalite / Plexiglass)
6. Omega 9300 Co-Axial – The High-Tech Chronograph
The 9300 is undoubtedly the flagship chronograph movement from Omega as it combines the key features of the 8500 with a ratchet chronograph . Due to the surplus of mechanics, the movement is correspondingly high. It is therefore only used for larger models from a housing size of 43.5 millimeters (Aqua Terra Chronograph). As far as the application is concerned, the display is especially good because both the stopped minute and the stopped hour can be found on the right hand counter. Thus, the approximate stop time is read in the same place as a current time.
Known for the Omega Speedmaster Professional in the co-axial version and the Omega Speedmaster Darkside of the Moon. The variant with the caliber designation 9605 shown here also has a second time zone and is used for GMT chronographs of the Aquaterra model series.
Built in: Omega Seamaster Planet Ocean Chronograph, Omega Speedmaster Dark / Gray / White Side of the Moon , Omega Seamaster Aqua Terra Chronograph, Omega Speedmaster Professional Co-Axial
7. Omega 1863 – Premium Variant Of The 1861
The Omega 1863 manual hoist is the premium version of the caliber 1861. Although it is more or less identical to its brother, it was additionally rhodium-plated and equipped with some even more high-quality work components. The work is installed in the sapphire glass version of the Speedmaster Professional, which, in addition to the components made of sapphire glass, explains the considerable price difference to the standard variant with Plexiglas.
8. Omega 8900, 890X Master Co-Axial – First Omega Factory With METAS Certification
The Caliber 8900 is the first movement that, in addition to the COSC certification, also runs through a procedure approved by METAS, the Swiss Federal Institute of Metrology. Apart from that, it is basically an Omega 8500 with date display at 6 o’clock. The benefit of the METAS gait test is that, in contrast to the Chronometer test, the natural wearing behavior is simulated. Water resistance and magnetic resistance are also tested. The watch is built into the Omega Globemaster – it is quite possible that this extended procedure will soon be used in many other Omega models.
9. Omega 3330 Co-Axial Chronograph With 3 Totalizers
While the 9300 chronograph movement is a pure manufactory, the 3330 is based on the ETA / Valjoux 7750 in the widest sense, with the work being modified at several crucial points. Thus, the current variant has about a column wheel circuit and a co-axial inhibition. Although Omega models with 3330 do not have a “15,000 Gauss” lettering on the dial, the 3330 has an increased magnetic protection by means of a non- magnetic silicon coil. On occasion, it can be seen that the 3330 is a work that comes from the same family as the former Omega 3313. The latter is, however, based on the Frederic Piguet 1285. Installed
10. Omega 8520/8521 Master Co-Axial – High-Tech Caliber For Women’s Watches
Considering the enormous effort that flowed into the development of the Omega 8500, it is no surprise that the world of ladies’ watches is to be explored with the 85th caliber family. In view of the small size, the 8520 impresses with outstanding performance. It also does not bother you, that compared with the bigger brother with a reserve of 50 hours must be 10 hours shorter.
elevator rotor made of gold. As far as the flywheel is concerned, this is not only influenced by the optics: since gold has a significantly higher specific masscompared to steel , the kinetic energy of the hand movement transfers particularly well to the elevator rotor. Especially with larger translations, the clock runs at a quick rate.
