The chronograph is arguably one of the most useful complications in watchmaking for the AAA US replica watches. It allows for precise control over the movement and the ability to time things down to a fraction of a second, some even allowing splits, on-the-go flyback, and high-frequency timing.

But the one that enters into the realm of useless is the 1/1000th of a second chronograph, most famously exemplified by the high quality fake TAG Heuer Mikrotimer Flying 1000 watches.

The reason it is useless comes down to biology for luxury replica watches: human reaction time is, on average, around 0.25 seconds, possibly up to 0.15 seconds in ideal conditions. Did you see how that was measured? With two decimal places because anything more is leaving the realm of significant figures.

Human reaction time is never fast enough to need anything more than 1/100th of a second precision, and in a majority of cases anything over one-tenth of a second is probably too fine to really distinguish for most people.

The level of precision for perfect copy watches in a 1/1000th of a second chronograph is for no other purpose than because they can: no human can take advantage of the fine graduations after one considers all the factors involved in reacting and pushing a button.

But who cares! The engineering behind such a mechanism for the best fake Tag Heuer watches is the incredible part: getting components to move that fast . . . starting and stopping and starting again is seriously hard on the tiny components.

The forces engineers had to overcome were significant, including challenges related to power consumption, lubrication, and the high precision tolerances necessary.

Sure, you can’t take advantage of it in any appreciable way, but you can cheap online super clone watches it fly around the dial and pretend like you actually tried to stop it at a different point each time instead of it being more the result of the interactions of the components and your slow biological processes.
