A Critical Look At The A. Lange & S?hne Grand Complication II

Let's start with the perpetual calendar. A.Lange&Sohne replica uk has produced perpetual calendars before (even a Rattrapante Perpetual), so here we are getting a very finely tuned complication. The display is different though than with previous renditions. All four years worth of months, as well as the leap-year indicator itself, are contained in the subdial at 12 o'clock, while the day of the week is off the the left and the date off to the right. Down at 6 o'clock is the moonphase, nested inside the flying seconds.

There are cases to be made for and against displaying the months in this way. While the larger subdial does make it relatively legible, it's certainly not as easy to read as a subdial with only 12 months. But, on the other hand, there is something poetic about seeing the entire cycle. But, unlike most perpetual calendars that use these hand-and-register displays, the markings do not drift by continuously. Only the moonphase is in slow, constant motion – the other indications all jump instantaneously at midnight, yet another way in which the Grand Complication shatters expectations.

Moving to the chronograph, what we have in the Grand Complication is a split-seconds chronograph with a foudroyant, or flying seconds at 6 o'clock – 248 components, nearly 30% of the movement, are dedicated just to these functions. When you activate the chronograph, not only do the chrono and split hands start moving across the dial, but the small hand at 6 o'clock begins jumping across 5 positions, letting you time to 1/5th of a second. But, "Wait a second," you're probably thinking. "Does this mean that the balance in this replica tag heuer Grand Carrera beats at 5Hz?' No, and it doesn't have to. The flying seconds is powered by its own mainspring and has its own system of wheels to allow it to move 5 times per second, including that 30-tooth wheel you can see on the right in the photo below. The mechanics are complicated, but all you need to know is that as long as the balance is keeping good time at 4Hz, the foudroyant will be accurate to 1/5th of a second.

The split-second complication is something Franck Muller replica uk collectors have grown to love over the past few years, especially in the form of the Double Split. In classic Lange style, the split pusher is at 10 o'clock, not housed within the crown. This will get some Swiss purists upset, but it's true to what the brand has always done and the style of Glashütte more generally. So, while people can make the argument all day that it's the "easy way out," it is the most authentic execution here. You'll notice there is only one other pusher, up between 1 and 2 o'clock – this split is also a monopusher. Finally, the main chronograph function and the split function each have their own column wheel.
