Bokey TimeHello everyone, this is Bokey. In this review, I’ll be discussing a popular dress watch from Jaeger-LeCoultre – the Master Geographic Q142842. Before ZF Factory launched this Master Geographic model, all versions available on the market were inaccurate. This time, ZF has perfectly matched the original in terms of size and thickness. Additionally, the movement has been upgraded to an imported Japanese Miyota 9110 movement (from the same family as the Miyota 9015, with a high-frequency swing of 28,800 vibrations per hour for higher accuracy, with a comprehensive daily error within ±8 seconds), replacing the cheap domestic movements used in previous market versions. However, there are still some shortcomings. What are the specific flaws?
How does ZF’s craftsmanship compare to the authentic version? Bokey will point out these issues one by one in the article! First, let’s look at the official parameters: MASTER GEOGRAPHIC Master Geographic Series Watch, Model 1428421.
Generally speaking, when it comes to formal mechanical watches, we have to mention the Jaeger-LeCoultre brand, and Jaeger-LeCoultre’s formal wear styles are not only the simple business models that we know about every day, but also have high-precision complex models. ZF has always had a strong development capability in the Jaeger-LeCoultre brand, and since the previous launch of the Moon Phase Master, it has successively launched many styles such as the Ultra-thin Master and the Beichen series, and this time this complication is the first after the Joker. Next, let’s take a look at how the ZF geographer Q1428421 workmanship, and whether it will be fake at a glance compared to the original?
We can see the complexity of this watch through the function identified by the wave mark in the picture above, which is also destined to reproduce the difficult overcome, in addition to some small factories have been doing it before the launch of ZF, only the TWA factory has been doing it, but its size has been complained about, 43mm larger than the original 39mm, 4mm. In terms of thickness, it is also about 2mm thicker than the original. This makes it uncomfortable to wear, and the movement uses the original movement bridge modified from the domestic movement.
The 39mm x 11.9mm calibre is the same as the original movement, and the movement is based on the stable Japanese MIYOTA.9110 calibre Jaeger-LeCoultre CAL.939A/1 movement, which realizes all the functions of the original – including hours, minutes, seconds, date, 24-hour display, region display and power reserve indicator. The repair rate is extremely low! Later, the specific tuning function wave will be recorded one by one, and then look at it!
The white dial features numerous functional designs. In addition to the central three-hand design, there is a power reserve display at the 10 o’clock position, a pointer-style date display at the 3 o’clock position, and a second time zone display at the 6 o’clock position with a 24-hour display disk to distinguish whether it is noon or midnight in the second time zone. The crown at the 10 o’clock position of the watch can be used to adjust the regional time display of the watch.
The hour and minute hands are yin and yang needles, and one side is polished and the other side is frosted. The second hand is a burnt blue hand, and the three-dimensional hour scale is distributed on the silver-white dial, which makes the texture of the whole watch to a higher level.
From 9 o’clock to 10 o’clock: the kinetic energy reserve system, which provides a power reserve of at least 40 hours when fully wound, and the kinetic energy is displayed as real and not cosmetic, but is indicated by the tightness of the mainspring
The date dial from 2 o’clock to 3 o’clock can be adjusted by the button on the right. This is the same operation method as the original
The crystal is made of high-transparency sapphire glass and treated with an anti-reflective coating, so that the texture is clear and translucent, so that you can see it at a glance.
The case material is made of imported stainless steel, the entire case is polished and polished, and the left handle is displayed for the adjustment area, which can be adjusted directly up or down. The size of the head LOGO is the same, the blue is the protective film, and you can tear it off after receiving it. In terms of thickness, ZF synchronizes the genuine product, achieving 11.9mm, which can achieve the same thickness as the genuine product, which is very rare in the category of formal tables
Look at the other side, the middle is the time adjustment handle, and the upper right is the calendar quick adjustment button, which can be adjusted with the tools that come with the factory.
ZF Jaeger-LeCoultre Geography Master q142842 compared with genuine time-adjusting function is good, true and false flawsSummary:
1.When the left-hand hand is displayed in the adjustment region, the hour hand of the second time zone of the authentic Jaeger-LeCoultre University of Geography will be linked, while the ZF version will only adjust the region.
2.The ZF version of the calendar adjustment button is a little deviated from the position of the genuine product, but the function is the same, you can see from the comparison chart at the end of the article.
3.Mainly in the way of adjusting the second time zone, the genuine adjustment method is to adjust the hour hand of the second time zone separately by pulling the first gear of the handle, and the ZF Jaeger-LeCoultre geography master is to adjust by opening the second gear (the first gear is a vacant gear), the adjustment method is to rotate the minute hand of the second time zone counterclockwise, the hour hand of the second time zone will not be linked when adjusting, and if it is adjusted clockwise, it will be linked with the regular hour hand and minute hand.
4.The movement adopts the Japanese Meiyuda 9110 caliber Jaeger-LeCoultre CAL.939A/1 movement, through the sapphire mirror we can see that ZF’s processing method in this movement is to directly polish and engrave the words on the original core deck, which is different from the deck machine on the market, which increases the stability! Everyone knows that the headache of the deck machine is that the parts of the fake deck, the screws will fall off due to external force after wearing for a long time, and once they fall off, the movement will fail. As for the flaws in the movement, I won’t go into them one by one, this discussion doesn’t make much sense, after all, the price and craftsmanship are there. I believe that all cousins will also agree with what Bokey said, playing the watch is to have a good time and save money, and it is fun to worry about too many true or false questions.
5.Like the original product, the buckle has Jaeger-LeCoultre’s patented quick-release function, which can be completed without tools when the buckle is better
6.The strap is made of black hand-stitched Italian cowhide pressed crocodile pattern, and the texture is moderate, of course! If you want to wear the same experience as the original product, Bokey here recommends upgrading and replacing the American alligator leather strap.
Next, let’s take a look at the ZF factory geographer Q1428421 compared to the original original:
Another mention here is about the functions of the ZF Q1428421 watch, which Bokey will briefly talk about here. The analogue date display at 3 o’clock allows us to adjust the date with the tool that comes with the purchase of the watch, i.e. by pressing a correction pusher at 2 o’clock on the watch case. In order to improve the longevity of the movement, Bokey would like to remind you that the watch should not be corrected on the wrist between 8.30 and 3.30 a.m., because it is during this time that the calendar gears are engaged in the snapping of the calendar. The second time zone display at 6 o’clock has a 24-hour dial next to the second time zone to distinguish whether the second time zone is noon or midnight, and below it is the GMT time zone selection setting. The crown at 10 o’clock allows the watch to adjust the time zone of the watch. ZF also launched a rose gold version, of course, this rose gold version is made of PVC plating, not real gold, the pursuit of texture friends can find Bokey to do gold processing. In the future, Bokey will make another evaluation of the rose gold version
Summary: This Jaeger-LeCoultre Geographer Master Q1428421 from ZF is worth buying in terms of detail and size. As for some deficiencies in the regulatory function, this depends on your psychological expectations.
