Lunar Speedmaster is the most unique watch in Omega series. On the one hand, the Omega Lunar Speedmaster has a history of entering the space and landing on the moon; on the other hand, the Lunar Speedmaster is a very rare hand-wound chronograph in the same class of Omega watches. . Veteran players will know that for a long time, Omega Speedmaster / Lunar Speedmaster and Patek Philippe both use the ‘same’ manual timing movement.

Astronauts wear Omega Lunar Speedmaster when they go to the moon.
 Omega: From 1957 to 1968, Omega used the Omega 321 manual chronograph movement on the Speedmaster / Lunar Speedmaster chronograph.
 Patek Philippe: Since the mid-1980s, the 3970 chronograph perpetual calendar and the 5970 chronograph perpetual calendar have used the Patek Philippe CH27 manual chronograph movement.
 The Omega 321 movement and the Patek Philippe CH27 movement are actually the same movement. (Due to different brand positioning, polished and decorated movements, different structural details, but essentially the same movement). Except for Omega and Patek Philippe, which are both world-renowned watch brands, they have different positioning and different pricing. There seems to be no overlap. Why use the same movement, there is a story in it, everyone looks down.

Omega’s Speedmaster Chronometer (top) and Patek Philippe 3970 chronograph calendar (bottom) launched in 1957. They use essentially the same movement.
 In 1930, in order to strengthen its strength, Omega and Tissot jointly established a watch group called SSIH and began to share technology and markets. This Omega and Tissot combined group is the predecessor of today’s Swatch Group. Two years later, Lemania, a well-known watch / movement maker, joined the group (Lemania is now a movement factory under Breguet), becoming an alliance of Omega, Tissot, and Lemania. After that, Omega and Lemania began to develop a new chronograph movement, project code CH27 C12. After technical research by Omega and Lemania, they were finally completed. Omega calls this movement the Omega 321 movement, and Lemania refers to the new movement as the Lemania 2310 movement. Because of the excellent performance, structure, and appearance of this new manual winding chronograph movement, major brands have begun to use it, including Patek Philippe, Audemars Piguet, and Vacheron Constantin. Among them, Patek Philippe further decorated and modified the movement to become the Patek Philippe CH27-70Q movement, which is used on the 3970 and 5970 chronograph calendars.

 Although Omega was the developer of the 321 movement, in 1968, Omega stopped using this movement on the Lunar Speedmaster, replacing the 321 with a 861 manual winding movement (currently used on the Lunar Speedmaster on sale). It is an upgraded model of the 861 movement, the 1861 movement, which shows the historical inheritance and pedigree of the Omega Lunar Speedmaster). In 2011, Patek Philippe launched the self-made CH29 manual chronograph movement instead of the CH27 movement.
What kind of movement is the Omega 321?
 The Omega 321 movement is a hand-wound movement that combines durability and beauty. When Omega and Lemania jointly developed this movement, the code was positioned as CH27, where 27 represents the movement size of 27 mm. The Omega 321 movement has a diameter of 27 mm and a thickness of 6.74 mm. Like today’s 7750 chronograph movement and El Primero chronograph movement, the dimensions are all 30 mm, so the Omega 321 movement is a relatively small chronograph movement.

Omega 321 movement, because the main plate of the movement is not rhodium-plated, so it shows a red copper color, which is also a major feature of the antique Omega movement. Has a high degree of recognition.
 The Omega 321 movement uses the most traditional manual chronograph construction, uses column wheels to control, and uses horizontal clutches. The petal-shaped shape of the columnar wheel reduces the friction stroke of the lever movement when the chronograph starts / stops / returns to zero, and the chronograph operation feels smooth. At the same time, the shape of the cylindrical wheel is more beautiful. The horizontal clutch structure of the Omega 321 movement is also very classic and very beautiful. The running seconds wheel and the chronograph second wheel are meshed / disengaged by the clutch gear. The Y-shaped splint of the fixed chronograph second wheel and chronograph minute wheel has a very high recognition. Various levers, splints, and gears are intertwined and have a strong ornamental effect. It is precisely because of these characteristics (mainly beautiful) of the column wheel and the horizontal clutch that the top chronographs generally use a configuration combination of the column wheel and the horizontal clutch. This movement takes into account both performance and beauty, so all brands including Patek Philippe, Vacheron Constantin, Audemars Piguet will use this movement one after another.

 The Omega 321 movement uses 17 jewel bearings with a swing frequency of 18,000 times per hour and a power reserve of 44 hours. There are small seconds, 30 minutes, 12 hours, 3 small dials. Another technical detail is that the 321 movement uses an instantaneous minute chronograph hand, and every 60 seconds in the timekeeping, the minute chronograph hand jumps one grid to point to the next minute. Although in today’s chronographs, instantaneous minute chronograph hands are not uncommon, in the era of 321 movements, most chronograph minute chronograph hands are slowly crawling (referring to the minute chronograph hands moving slowly instead of Jump directly from 1 minute to 2 minutes).

What is the difference between the Omega version and the Patek Philippe version.
 Lemania2310, Omega 321, Patek Philippe CH27, although all are essentially a movement, but different brands, according to their own circumstances, have modified the movement. Someone made a special comparison between Omega 321 and Patek Philippe CH27. By marking different colors on the picture, it can be clearly seen that the structure of Omega 321 and Patek Philippe CH27 is different. The Omega 321 movement is mainly used on the Omega Lunar Speedmaster. The Lunar Speedmaster is a professional watch on the universe. It pays attention to performance and has a solid bottom cover. The movement takes performance and durability as the primary task. , 5970 chronograph perpetual calendar, 5070 chronograph. For positioning reasons, Patek Philippe has the Geneva mark and the current PP mark, plus a transparent bottom. The movement is most important to be beautiful and polished.

Patek Philippe CH27 movement (top) and Omega 321 movement (bottom). Although the two movements are essentially the same, pay attention to the differences in details.
 From the comparison chart, we can clearly see that Patek Philippe changed the splint with a fixed second wheel and clutch size to an S shape, and Omega used a thick splint (pink part). Patek Philippe has made the splint and zero-reset lever of the fixed chronograph second wheel thinner, and Omega is thicker (green part). At the same time, Patek Philippe put a cap on the column wheel, and Omega kept the column wheel as it was. Patek Philippe has replaced the card-free fine adjustment weight balance. Omega uses the original fast and slow needles. The Omega Lunar Speedmaster and Patek Philippe 3970/5970 have different functional directions (the times are also different), so that there are two completely different versions of the same movement. very interesting. This also reflects the strong strength of Omega and Patek Philippe in their respective fields.

Omega 321 movement
 Finally, I want to tell you something unexpected. Just yesterday, Omega announced that it will resume production of movement 321! This is also after OMEGA stopped using the 321 movement in 1968, after 51 years, restarted the 321 movement again. Omega said that in order to re-produce the 321 movement, the research and development team of Omega has secretly researched and developed for 2 years, and based on the last moon landing Super Speed ​​321 movement on the moon in 1972 as the model for the new generation of 321 movement design .
 This year marks the 50th anniversary of the human landing on the moon, and also the 50th anniversary of the landing of the Omega Lunar Watch. Omega’s restart of the 321 movement will inevitably make a big deal and launch a new heavyweight watch. Let’s look forward to it.

Graceful appearance born bright

 This can be used as a prelude to a movie, a film starring Cameron Diaz and challenging a new role: the ambassador of TAG Heuer and the inspiration for the new Ms. Lincoln watch collection. Designed for elegant and breakthrough women, this new collection is a natural fit on the wrist of this Hollywood star. ‘I want more than just a watch, but a piece of jewelry. When I wear it on my wrist, I want the’ wrist ‘to be empty. It is dazzling, feminine, and comfortable to wear.’ She told the design team.
 This is the story behind these exquisitely crafted, plump watches with case diameters of 29 mm and 34.5 mm, with central lugs. The watch is equipped with a quartz movement, a date display at 6 o’clock, and a faint concentric Newseau pattern on the dial.
The highly representative S-shaped link LINK bracelet has been redesigned. The design follows a simple principle: to bring elegance, comfort and poetic feelings to create pure joy.

S … born for brilliance

 In the film, some women can naturally radiate attractiveness. Their smiles are synchronized with the camera, touching the heartbeat of the audience, their charm is far beyond the camera. They are called stars because they are the most dazzling focus on the screen.

 The Ms. Lincoln collection has its own sparkling jewellery: star-shaped diamonds shine brightly, which is extremely feminine, highlighting the essence of this series of watches. Infected by the Haute Couture, it has transcended the constraints of time and gravity, like a Haute Couture show on the temple. The automatic movement is suspended, the swing of the oscillating weight is like a superb ballet performance, and the diamonds flash like meteors in the Milky Way. The dial and case back seem to blend together, allowing the designer to immerse himself in the creation of the starry sky dance.
 The reason why such elegant artwork can be shaped is thanks to a larger rotor that is larger than the movement. In order to operate without affecting the design of the sky, the calculation of the volume of the oscillating weight must be extremely accurate. The oscillating weight rotates 360 ° between two sapphire crystals, allowing the naked eye to capture every timeless moment. The two layers stacked together keep the movement in the center of the case, making it look like it is floating. Every part of the entire structure is extremely precise in cutting to achieve the best results, while high-end technical requirements such as sapphire crystal glass are extremely demanding. The entire structure is completely transparent, and no joints can be seen between the two layers. This can only be done after a precise, dust-free and long assembly process.

 The watch body is entirely covered in 18K 5N rose gold and set with 192 diamonds weighing 1.35 carats, gorgeous and dazzling. It is a miracle of the perfect combination of machinery and aesthetics. It is the most eye-catching star, the most dazzling star group, and the gorgeous beauty at the ball. This top-notch work heralds the future.

S … Born for elegance

 This series also has a watch with a diameter of 29 mm, the case is entirely made of rose gold, the purple dial is set with 11 diamonds, beautiful and moving. Roman numerals engraved on the bezel exude a timeless elegance. It’s the perfect choice for lighting up dark suits, and it’s also an ideal companion for busy women in the workplace. The double tone of steel and gold, combined with diamond or Roman numerals, gives a rigorous yet elegant feel.

S … Born for charm

 For those who prefer stainless steel without sacrificing luxury, 47 diamonds with a diameter of 1.4 mm and a total weight of 0.52 carats will make you beautiful. They settled securely on the bezel and complemented the 11 diamonds on the dial. Under their bright light, the watch is more like a jewel. For the wearer, this watch can not only display the time, but also bring joy.

S … born for style

 Finally, this series of watches has the essence that every elegant woman pursues: pink roses, a fluorescent white mother-of-pearl dial set with 11 diamond hour markers, and a polished steel bracelet and case. Even the most minimalist style—white Neuss background with Roman numerals—whether it is a 29mm or 34.5mm diameter model, Ms. Lincoln’s fashion style is unstoppable: after all, a beautiful figure can control any fashion, Is it straight pants or a horn?
