Chronograph Of Turning Zero Into Integers Tasting Jaeger-lecoultre Geophysical Observatory Watch

Since the middle and late 19th century, geophysics has been a very important but little-known exploration activity in human history. Many countries have set up geophysical societies or related institutions, many polar explorations, astronomical observations, etc. It is up to them to explore the mysteries of nature. In order to commemorate this challenging exploration activity that greatly promotes the development of human natural science, Jaeger-LeCoultre specially set up a series of geophysical observatories. This year, the theme of ‘real seconds’ is filled with a strong stroke for this series. Q8012520 is one of the precious metal three-pin watches, and the steel model launched together is even more sought after.

   I believe that many watch friends are no stranger to ‘true seconds’ (that is, jumping seconds). This is the iconic walking seconds form of quartz watches, and is still used by many friends as one of the criteria to distinguish quartz watches from mechanical watches. But if you see this watch, this standard is invalid. The traditional mechanical watch’s walking seconds are continuous ‘sweep seconds’, because the high-frequency vibration of the escapement is directly output to the second hand, so the movement of the second hand every second includes multiple vibrations. ‘True seconds’ turns it into zeros, which explains another timing program for mechanical walking seconds.

Jaeger-LeCoultre Geophysical Observatory Series ‘True Seconds’
    In 2014, Jaeger-LeCoultre has launched several special watches to commemorate the International Geophysical Year. This year, it has been sublimated on this basis. The commemorative meaning is the same, but many modifications have been made to the overall design. However, as the theme watch of the Geophysical Year, it is natural to uphold the spirit of scientific exploration. Therefore, in terms of design, it does not follow the retro line, but rather it means more daily companionship.

18K Gold Crown
   This type of crown has a very cute name-‘moon cake’, just because it looks like it. This is one of the most commonly used types of crowns for day-wear watches. The anti-slip texture is excellent, and the surface is branded with a brand logo. In addition, the texture and feel are fine examples.

Alligator leather strap
   The watch is paired with a precious alligator leather strap, which is carefully sewn to ensure that the strap is durable. Crocodile leather has long been a standard feature of high-end classic models, and is popular because of its soft leather, no odor, and unique texture.

Brushed and polished case

   As mentioned earlier, the positive geophysical observatory watch has not completely changed the design style of the classic Tibetan model. From the appearance of polishing, it can be seen at a glance. The bezel and bottom cover are polished to enhance the frontal texture of the watch, giving a deep impression, while the middle bezel is brushed and polished to complement the polished bezel, which is bright and dark.

Refreshing layout

   What makes this watch so fascinating, in addition to the features and unique meanings mentioned earlier, the clear and readable dial also plays an important role. The silver grained dial, appliquéd Barton gold hour markers, and the 6-point black font ‘TRUE SECOND’ indicate the speciality of the watch. The hour, minute hands and the inner side of the bezel are supplemented by mainstream Super-luminova fluorescent materials, allowing the watch to read clearly even in dim conditions.


   Compared to the elegant curved ears of most classic Japanese models, the earpieces of the Jaeger-LeCoultre Geophysical Observatory Real Second Watch are undoubtedly much wider, slightly curved, polished, and the tail is cut to match the thickness and frame of the watch Brushed and polished, so that the watch in the subtle and subtle texture, full of egotistical sense of grandeur.

Pin buckle

   The 18K rose gold’s moist hue makes the pin buckle more intimate. Pin buckles have always been a classic match for formal watches, with simple structures and secure locking methods, making them the most mainstream buckle style.

Jaeger-LeCoultre’s first 770 automatic movement

   For this unique watch model, Jaeger-LeCoultre specially developed the 770 automatic winding movement. In addition to exquisite and beautiful polishing, the biggest feature is the Gyrolab balance wheel developed by Jaeger-LeCoultre’s great efforts, and for the realization of Special structure equipped with the seconds jump function. The biggest advantage of Gyrolab balance is that it can improve the travel time accuracy. In the ideal state, it can reach between positive and negative two. As a mechanical oscillating structure, such accuracy is shocking enough.

Summary: Although mechanical watches implement chronograph programs such as jumping seconds, they rarely exist because they are simple to control, complicated and difficult to make, and this is not a very useful function. Jaeger-LeCoultre chooses to jump seconds. In addition to its strong technical support, it can quickly gain consumer recognition through this series. One hop and one second, turning zero into whole, between time capture and vertical, why isn’t it the true meaning of exploration embodied in geophysics?
