Hamilton has a lineup of a mix of mechanical and quartz. There are several models from Hamilton with a quartz movement, but many are limited to displaying the time and date. The Khaki Aviation Chrono World Timer Quartz, which is preparing to be stocked in Korea in September, features rich functions and mode switching.

This model is said to have been designed with Nicholas Ivanov, an aerobatics pilot and Hamilton ambassador. That’s why we show up to the 20th minute of the minute index in yellow. This part, which is also an accent on the dial, represents the four-minute time limit in aerobatic competitions. If it goes over 4 minutes, there will be a penalty, so it should not be longer than 4 minutes. But the question arises here. Why are you talking about a 4 minute time limit while the 20 minutes are marked in yellow? This is due to the unique counting method of the Khaki Aviation Chrono Worldtimer Quartz. In a normal chronograph, the chronograph hand advances one division of the 30-minute (or 60-minute) counter every time the dial is rotated. Because of the way you advance by the minute. In summary, it is a method to display a more readable display by expanding the time limit of 4 minutes. You can’t afford to read the finely printed quarter scales on a mind-blowing aerobatics plane. Nicholas Ivanov might have emphasized this point. So the dial doubles as a large counter, and the window between 9 and 11 is a 120-minute counter. The 6 o’clock position is the permanent second hand. This configuration is difficult to see in mechanical chronographs.replica watches
The feeling of pressing the push button is inevitably different for a chronograph using a quartz movement compared to a mechanical chronograph with physical movement. In general, the push button of the quartz chronograph feels relatively light, but the Khaki Aviation Chrono World Timer Quartz uses a spring with strong elasticity to feel a little more pressure, so there is less discomfort. It’s not so light that it’s embarrassing for your finger to press hard, but it’s a fairly dull feeling. Pushbuttons follow the usual way. Except for the fact that the 2 o’clock position is the start/stop and the 4 o’clock position is the reset button, and when the start button is pressed, the chronograph hand starts moving one step at a time. There is no difference. Rather, it is more stable than the mechanical type, which reveals relief depending on the clutch method at start.
The interesting thing about the Khaki Aviation Chrono Worldtimer Quartz is that it takes advantage of the quartz movement. Press and hold the mode button at 10 o’clock on the case for about 3 seconds to switch from the chronograph to the world timer. The display of the mode window spanning the 2 o’clock and 3 o’clock directions shows that the mode has been switched from Chrono to Time. The push button, chronograph hand (white tip), center counter hand (yellow tip) and the 120-minute counter from this point forward become buttons and indicators for the world time display. The chronograph hand points to the time, the central counter hand points to the city name, indicating the time of the city, and the 120-minute counter hand turns into a day/night indicator. Each time the Start/Stop button is pressed, the central counter hand jumps counterclockwise to indicate the city name, and the chronograph hand also jumps to indicate the time in hourly increments. If you press the reset button, the same operation is performed, but in this case, it moves in a clockwise direction. So you just have to decide whether to press the start/stop button or the reset button depending on where the city name you want to know is located. I heard that Baselworld 2015 was programmed to automatically display daylight saving time. It probably reflects the ability to automatically display daylight saving time (daylight saving time). Daylight Savings Time is a system that aims to optimize the change of daytime in summer to the active time. As it usually starts in the summer season or when the days are getting longer, if you want to implement it through a program, you must count the year and the city of application inside the movement. In a quartz movement that is not difficult to implement a perpetual calendar function, this is also not too difficult, but in a review model that can only display a date, it is not possible to know what month it is now, so the question arises as to whether the daylight saving time is displayed properly from the user’s point of view. Perhaps you can determine this in the initial settings, but the operation of this part is not yet clear.
It uses a screw-down crown to reliably respond to 100m water resistance. When the crown is released, it is position 0, when it is pulled one position it is position 1, and when it is pulled one position it is position 2. If mechanical, winding at position 0, but no motion at crown 0. When position 1 is reached, the chronograph hand, the center counter hand and the counter hand all return to 0, and when the crown is turned, only the hour hand can be moved in increments of one hour. This is a common method found on GMT watches. The method of changing the date by continuously turning the hour hand is the same. The feeling of moving the hour hand by turning the crown is very similar to that of a mechanical one. In position 2, the feeling of turning the needle with the crown for time adjustment is also similar to that of a mechanical one. When the operation is completed and the crown is pushed to position 0, the state immediately before the crown is released is remembered and returned as it is.replica audemars piguet
A stainless steel case with a matte finish for the hairline finish. It has a dignified physique with a diameter of 45mm, but the thickness is also quite reasonable considering the diameter. Mechanical chronographs are usually thick as the thickness of the movement determines the thickness of the case. The quartz movement does not have a relatively large increase in thickness even as a chronograph, but it has the same thickness as a mechanical chronograph and is also heavy. The crown and pushbuttons are polished to act as accents in the matte case, and at the same time distinguish them as movable parts. The case back is a solid bag and is decorated with an engraved image of an airplane orbiting the earth.
As shown in the image, you can choose a stainless steel bracelet or a rubber band, and a leather strap version is also available. The rubber band has a structure that adheres perfectly to the case, and the inside of the rubber band, that is, the part that contacts the wrist, uses a pattern that repeats Hamilton’s initial H to prevent it from slipping on the wrist. The rubber band is thick enough to consider the thickness of the case and lug, and has sufficient support.
Few fake watches have a chronograph and world time at the same time. Even if there is, it complicates the dial configuration. That’s part of the appeal of a watch with two functions, but it can also feel distracting. The Khaki Aviation Chrono Worldtimer Quartz takes advantage of the mode-switchable quartz movement so that it can be displayed clearly and without distraction. This is thanks to the Caliber H41e, an exclusive movement equipped with Khaki Aviation Chrono Worldtimer Quartz. Hamilton is segmenting the demand group with a model that combines the strengths of each method with the functional excellence of quartz and a heavy case that is relatively difficult to find if it is not a mechanical (chronograph). It is a brand-down movement that utilizes the given resources (movement) to the maximum using wit and unique techniques.
