The Trinity Omega Tool Table For Speedmaster, Seahorse And Ironmaster (Part 2)

Throughout history, war has brought a deep disaster to humanity. Because of the need to create tools adapted to specific military purposes, war objectively promoted technological and economic development. For the most part, these tools have subsequently evolved into non-military equipment and have spread new technologies through various other areas.

Omega Speedmaster CK2915

Omega Speedmaster CK2915
   The Speedmaster is perhaps the most famous sports chronograph in watchmaking history, and it must be the most well-known of the Omega Trinity tool watches. Ironically, Speedmaster became famous not because it was a high-quality chronograph created for racers and team leaders, but because it was later selected by NASA as a standard timepiece to accompany astronauts to complete space missions and walk the moon. It is said that the design of the Speedmaster was inspired by the dashboard of the Italian sports car of that time. CK2915 was part of the Omega and Lemania project, which was then a subsidiary of Omega. The Speedmaster CK2915 prototype was ready at the end of 1956 and was released in 1957 with two other tool watches.

   Collectors call the first Speedmaster a ‘broad arrow’ because the hour hand has a large fluorescent arrow on the top, which is unique. The watch face is clean and tidy, without any frills that could impair legibility. The stainless steel bezel was engraved with the tachymeter scale and matte finish, which was also very novel for the chronograph at the time. The Speedmaster CK2915 is triple-protected, water-resistant to 200 feet (about 60 meters), and durable. Some details are often overlooked, but it is they that make this watch stand out, such as the vertical position of the chronograph second hand and the speed bezel are completely flat.

   The movement equipped with the first Speedmaster watch originated from a research project in 1942 and came from the famous Albert-Gustave Piguet. This movement is called 27 CHRO C12 (27 refers to a diameter of 27 mm, CHRO refers to the chronograph function, 12 refers to the cumulative 12 hours), it was renamed Omega Cal. 321. This movement uses a column wheel design. The initial version is not shock-resistant. In 1946, shock absorbers and anti-springs were added. The legendary 27 CHRO C12 (Cal. 321) is the first movement with a 12-hour cumulative chronograph function, and it is still one of the smallest chronograph movements to this day.

   The Speedmaster CK2915 comes in several versions (including very early variants and changes to the -1, -2, and -3 on the reference model), which can be considered a small update. CK2915-3 is a transitional model, Super Speed ​​began to change, and finally launched the CK2998 watch in 1959. The Speedmaster CK2915 watch produced very little between 1957 and 1959, so it was very rare and very expensive. We can say that the advent of the Speedmaster immediately and independently changed the face of the chronograph. It all started in 1957.
Omega Ironmaster CK2914 watch
   Due to the lack of continuity in the product line, Tieba is the least known of the Omega Trinity Tool. Tieba is rooted in highly accurate railway watches, as well as Omega RAF-53 CK2777 with antimagnetic protection. IWC was the first to explore enhanced antimagnetic protection (Mark Pilot’s Watch) and was the first to introduce such a watch to the market (1955, Engineer Ref. 666). Omega Ironmaster followed, this is the right tool watch.

Omega Ironmaster CK2914 watch

   Omega Ironmaster watches are designed for scientists and engineers whose jobs are often exposed to strong magnetic fields. The magnetic force generated by large engines, alternators, and power stations can seriously affect the timing of ordinary watches and even stop them completely. Omega created a triple-protected watch and made it magnetically insensitive with several key improvements. As an important aspect of anti-magnetic, the dial of Ironmaster watches is 1mm thick, far exceeding the 0.4mm standard of ordinary dials. The case is made of Huguenin Frères and is made of nickel-chrome corrosion-resistant malleable steel. It is 38 mm in diameter and has a screw-in case back. In addition, it is equipped with NuMetal soft iron inner plates to form a Faraday cage to protect the movement. Therefore, Omega Ironmaster watches are not only shock-proof, but also resistant to magnetic fields of up to 1,000 Gauss.
   Despite providing such complete protection, the Ironmaster has not survived: the model was discontinued in late 1963. The CK2914 is available in multiple versions (reference models -1 to -6, plus the last Ref. 135004 in the series), all of which can be seen as minor decorative updates. The common change for all sub-models is the pointer. About a year later, Omega replaced the wide arrow pointer with a toffee and a rod pointer.

   Another thing that makes the Ironmaster very interesting is its two military versions. The Pakistani Air Force (Pakistan Air Force) version delivered in 1961 is almost the same as the civilian version, except that the former dial is decorated with the word ‘Seamaster’, the back and movement are engraved with the abbreviation ‘P.A.F’, model number 2914. Thereafter, the smaller second batch model was 135.004. The backs of these watches are decorated with seahorse and PAF logos, as well as exclusive serial numbers. According to Omega Museum statistics, sales totaled 277. There is also a rare military version built by Omega for the Peruvian Air Force (Peruvian Air Force), with an order date of 1959. Although the dial and case back are decorated with Flightmaster lettering and logos, this version uses Ironmaster’s case and movement.
   In all variants, the CK2914 uses a total of three different manually wound movements. Caliber 284 movement from 1957 to 1958. This movement is equipped with Breguet balance springs. In 1943, it joined the Incabloc shock absorber. The number of gems was 17 and the vibration frequency was 21,600 times per hour (3 Hz). It also provided a 43-hour power reserve. . The Caliber 285 movement from 1959 to 1961 was equipped with a ring balance instead of a screw balance. Then, Caliber 285 was replaced by Caliber 286, which used a flat balance spring instead of a Breguet balance spring. The Ironmaster watch became a high-tech victim, but it was also defeated by the hippocampus. Back then, diving watches were more popular. Nonetheless, these do not detract from the charming charm and extraordinary performance of the Ironmaster.
Omega Seamaster CK2913
   The Hippocampus was born in 1948 and is the 100th anniversary of the establishment of Omega. It is the oldest watch series in the brand catalog. Omega originally planned to position it as a sturdy and elegant timepiece for active individuals. However, the 1950s divers started to rise and gradually became the style features we see today (chronograph bezel, sturdy case, thick hands and heavy mirror). Blancpain (Legendary Fifty Fathoms Watch) and Rolex (Iconic Submariner) are the industry pioneers in the field of professional diving watches. Omega was naturally unwilling to fall behind, so the hippocampus CK2913 watch was born in 1957.

Omega Seamaster CK2913

   The hippocampus CK2913 watch is water-resistant to 660 feet (about 200 meters), sharing the design spirit and technological innovation with the Speedmaster CK2915 watch and the Ironmaster CK2914 watch. The case is made by Huguenin Frères. It is made of nickel-chrome corrosion-resistant malleable steel, with a screw-in case back and reinforced mirror. The Naiad crown is waterproof and moisture-proof. The main feature of the hippocampus CK2913 watch is the diving bezel, which is marked with a counterclockwise scale and decorated with fluorescent spots at 12 o’clock, showing the remaining diving time. The dial of the hippocampus CK2913 watch is the same as that of the Iron Bully, and the hands are the same as those of the Speedmaster and Iron Bully.
   The Hippocampus CK2913 is driven by the Omega Caliber 501 automatic movement. Caliber 50X movement was produced from 1956 to 1960. During this period, the movement has been improved many times, and its name has been changed. All movements have a diameter of 28 mm, a thickness of 5.55 mm (without calendar) or 6.40 mm (with calendar), and a frequency of 19,800 vibrations / hour (2.75 Hz). Among them, the Caliber 501 movement equipped with the first generation of the hippocampus CK2913 watch has 19 gems and a power reserve of 46 hours.

   The hippocampus CK2913 has many different variants, from 1-7, all equipped with the same movement, using the same dial and case. The 1-2 / 3 bezel is counterclockwise; the 3-6 bezel is clockwise. 1-2 / 3 with radium fluorescent wide arrow pointer; 3-6 with toffee pointer or narrow arrow pointer. The last -7 with a ‘lollipop’ second hand, probably to match the Speedmaster CK2998 watch. In 1960, CK2913-7 was replaced by CK14755, which was equipped with a different self-winding movement, Cal.552. Since then, the Omega hippocampus has undergone fundamental changes. Although beautiful in shape and highly collectible, the first generation of the hippocampus CK2913 watch (including sub-model) is not a favorite of collectors, this honor seems to belong to the military model equipped by the Royal Navy in the 1960s. Despite this strange phenomenon, the first generation of the hippocampus CK2913 laid the foundation for the comprehensive transformation of the Omega diving watch, making it closely follow the trend of the times. At the same time, this transformation has also created many extraordinary diving watches, and to this day, the hippocampus is still Omega’s most popular product series.


Glamorous Brief Comment On Girard Perregaux 1966 Series Time Equation Watch

Girard Perregaux 1966 series has added an annual calendar astronomical time difference watch to SIHH in Geneva 2012. Not only does the appearance inherit the consistent elegance of Girard-Perregaux 1966 series, but the ruthenium metal dial and time equation Functional responsibility highlights the uniqueness of this watch. Today, the Watch House brings you a brief review of Girard Perregaux 1966 series time equation watches. The official model of the watch is: 49538-52-131-BK6A.

 The time equation, also called ‘astronomical time difference’, is a fever-level function in the field of watchmaking technology. To enhance the technical value of this new model, Girard Perregaux is equipped with the newly developed Microvar cardless balance spring in the movement. The wheel frame is equipped with 6 correction screws and 2 weights, which can be independently adjusted. Improve the quality of swing and frequency, so as to improve the accuracy of the display of the almanac and astronomical time difference, and the movement of the movement from the sapphire crystal case back to see.


The watch’s functional layout is new, it can be said that it is a masterpiece of the combination of top-level timepiece function and elegant style. The watch is crafted in an 18K rose gold case with a 40 mm diameter design.


The so-called true solar time (also known as apparent solar day, true solar day, etc.) refers to the time interval between the real sun passing through the meridian of the place twice. But because the earth is in an elliptical orbit, its speed of movement and its distance from the sun are constantly changing, so the time of each true solar day is not the same.


The watch comes with a black alligator leather strap, which is soft and comfortable. The buckle adopts a pin buckle design made of 18K rose gold, which is simple and safe to wear.


The rose gold case has a diameter of 40 mm, a thickness of 10.72 mm, and a water resistance of 30 meters. It is only suitable for daily waterproofing. This thickness is also very comfortable to wear on the wrist.


The ruthenium metal dial is decorated with matte ray texture, and the bar-shaped hour markers and leaf-shaped hands are harmoniously arranged, making the time and function display more clear. The annual calendar function is displayed at 7 and 2 o’clock on the dial, and it needs to be adjusted once on non-leap year February 28. At 9 o’clock, the small second hand is displayed.


The mean solar day is the average of all true solar days in a whole year, and is also called the mean solar time. 1/86400 of a flat solar day = 1 flat solar second (24 × 60 × 60 = 86400 seconds in a day) as the basic unit of measuring time. Modern clocks are designed and manufactured according to this principle. Because this watch does not have sunrise and sunset time display, there is no need to design and manufacture according to the longitude and latitude of the user’s area.


The watch comes with a black alligator strap and a pin buckle in 18K rose gold.


Equipped with GP033M0 self-winding movement, it can operate through the crystal glass back. The movement has a diameter of 11.5 cents, has 287 parts, and 44 jewel bearings. It has a 46-hour power reserve and a shock frequency of 28800vph / 4Hz. The movement is also equipped with a Microvare variable inertia balance wheel (Microvare variable inertia balance wheel). The balance frame is set with 6 screws and two inertia weights, each of which can be independently fine-tuned to make the balance operation in the optimal state, improving the accuracy and stability of the travel time. .


Summary: The watch combines the elegance of modern aesthetics and the tradition of superb watchmaking technology. The watch is equipped with an ingeniously designed oval cam and annual ring system to show the time difference caused by the orbit of the earth between the years. At present, the domestic price of this watch is 282,000 yuan. If you want to appreciate the charm of the time equation, do not miss this watch.
