There is an indicator of the practicality of the GMT function. Some super-pragmatic watch factories have no complicated functions except three hands, but GMT is one of the few styles that they think is necessary. This shows the practicability. GRAND SEIKO is one of the few brands in the market that can be called ‘super pragmatism’. The Hi-Beat 36,000 GMT launched by their family a few years ago was very popular. At that time, there was a limited edition (model SBGJ005) because of its use. It is popular with the market due to the eye-catching design of the green and orange time hands. In 2017, a new style similar to the SBGJ227 was released. It also has a green face plate and an orange GMT needle, but the new pattern is a bit different. At the same time, after GS announced its independence from SEIKO last year, the brand logo changes also appeared in this SBGJ227. This time we will take a look at the two generations of Hi-Beat 36000 GMT with 9S86.
Hi-beat 36,000 GMT SBGJ005
This 36,000-rpm GMT model of GS won the small hand award at the Geneva Haute Horlogerie Award in 2014. This is SEIKO Seiko’s best electronic watch following the electronic ink women’s watch in 2006 (at the time there was this award), 2010 Spacewalk won three awards after receiving the best sports watch, but this is the first time that GS itself won the award, and it is a meaningful small pointer award, which can be regarded as another milestone in the international watch arena.
GS has used this kind of faceplate treatment on a few models, which is different from the machine-engraved lines. It uses Free Hand to radiate the lines, saying that it mimics the ridges of Iwateyama where SII watch factory is located. The organic touch is quite in line with Japan. Human aesthetics, the green side is also unique to the limited edition
In the past, the two-time function of the 9S movement was only available on the 9S5x and 9S6x with 8 vibrations (the current model is 9S66). After all, the GS style Chengdu has a three-pin plus date, and it is added to the 9S8x with 10 vibration The strategic significance is full of special (although the technology itself is not complicated). But instead of discussing the movement, this 9S86 model itself is more attractive but the exterior part. GS re-enacted the 44GS for the first time in 2013, and began to use this case style in an unrestricted general style; the exterior quality of the GS has always been praised by players, but their case work began from 44GS It seems to have risen to a higher level. On the one hand, this type of case has adopted higher specifications from the design stage to the actual manufacturing. Furthermore, the 44GS has a larger continuous plane on the outside. The test can also show the effort of the case from molding to polishing.
Although this most powerful polishing method is used on the bezel, the most impressive thing about the entire watch is that it is connected from the side of the case to the plane of the lugs. The entire mirror is flat and the reflected image has almost no Distortion, the top technology for case processing
In the past, the case of GS was mostly forged. However, the finished product also has a complicated three-dimensional feel comparable to cutting and forming. Moreover, the density of the steel after forging is higher, and the gloss after polishing is unmatched by simple cutting; the new 44GS watch However, the case uses two processes at the same time. After 13 times of forging and finally CNC cutting off a layer, the case formed has a very sharp three-dimensional effect without being polished. This is a closer look. The shape of the lug ends can be known.
This time, the same limited edition is introduced. The automatic disk uses the full-frame style commonly used in GS in recent years. The material is also anodized titanium, but this time it is golden. Full-frame automatic disks are mixed among players, but it is a pity to cover the movement
Lin Jingji, who is responsible for processing the case of the GS, introduced the so-called M6 grade polishing when grinding the bezel. This is the highest level of polishing used by SEIKO in the 1960s and 1970s, which is equivalent to Black Polish in Switzerland. The tin plate is used as a polishing material for polishing. Such a process has been useless for a long time on GS. The quality of the finished product is extremely high, but it is more prudent for related staff to hear such stories. .
Hi-Beat 36000 GMT SBGJ227
The aforementioned SBGJ005 has been very popular in the market because of its eye-catching design using green and orange time hands. Inspired by the old work, GRAND SEIKO launched a new product with a similar design in 2017. Generally speaking, the similarity between the new and old works is not low. The main difference is the modification method of the face plate.
From 2017, GRAND SEIKO will be separated from SEIKO and become its own independent sub-brand. In the past, the ” SEIKO \\ ” on the watch face has disappeared. It is directly represented by the GRAND SEIKO Logo.
SBGJ227 and the 2014 version of SBGJ005 have another obvious change. Because GRAND SEIKO announced its independence from SEIKO in 2017, the current GRAND SEIKO directly replaced the previous SEIKO and GS Logo with the 12-point GS Logo. Coexisting situation; another contrast between the new and old works is the 24-hour scale on the outer edge of the faceplate. SBGJ227 has been completely replaced with silver-white, while the 24-hour scale of the previous work is an orange color that echoes the GMT pointer.
The time models in the two places did not modify the movement much, but installing an additional needle on the center axis will affect the thickness of the face plate to the inside of the watch mirror. This is an important point that is often overlooked in the two places. The colors of the limited models from the face plate to the GMT needle are very delicate. This depends on the actual watch.
The 9S86 movement on the watch is based on a 5Hz (36,000 rpm) high vibration frequency setting. Theoretically, the higher the vibration frequency is, the more accurate the time interval is captured. The GRAND SEIKO manufacturer said that the machine The daily error of the core can be controlled between -3 and +5 seconds-which is higher than the level certified by the Swiss Observatory. Considering the large amount of kinetic energy consumption of the high-frequency movement, the 9S86 movement has 55 hours of movement. Although the storage space is not top-notch, it is already quite a sufficient setting with automatic refining mechanism.
The new peacock tail decoration pattern on the green face, plus the 24-hour scale becoming silvery white, etc., all revealed the modification clues that belong to the new version
The same as the old one, SBGJ227 is also made of stainless steel, with a diameter of 40mm, and has a water resistance of 100 meters, which is better than ordinary watches. Details on other faceplates, such as the brand’s proud Zaratsu mirror polishing, and the anti-glare coating on the sapphire mirror, need not be detailed one by one. If you think that the previous SBGJ005 was a little more conservative in terms of a limited edition work, then the appearance of SBGJ227 should make up for the impression score in this aspect, and it is even more pleasant that SBGJ227 is not only more than the more Rich visual hierarchy, this time his limited number has increased slightly to 700, and the price of the new US dollar is also cheaper than that of SBGJ005. In other words, for consumers who want to start this, the door to opportunity is also It has become wider, and it is really difficult to resist it this time.
