ZF Jaeger-LeCoultre Q1428421 Geo Master Watch: Ceiling-Level World Time Function Genuine Comparison

Hello everyone! I am a watch detective, and what I will introduce today is the Original Factory WatchesZF, a classic example of the Jaeger-LeCoultre Geomaster Q1428421. There has been one on the market before, but its size is 42 mm, which is 3 mm larger than the original. The movement also uses an old-fashioned oscillating weight, and this time ZF created not only the same size, but also the latest version of the movement structure.

Function and adjustment method

There is a 40-hour power reserve at 10 o'clock, a 24-hour day/night display at 7 o'clock, a second time zone at 6 o'clock with the corresponding place name, and a calendar at 2 o'clock. How these functions are used is a matter of course.

The 40-hour power reserve is increased by rotating the crown directly clockwise, the 24-hour day/night display is synchronized with the time and completes a full revolution after 24 hours of walking, the second time zone is adjusted by pulling out the crown on the right side of the dial and then adjusting the time difference clockwise and counterclockwise, and the place names are rotated by rotating the crown on the upper left side of the dial, and the calendar is adjusted by the small invisible hole on the upper right side of the dial.

ZF Geomaster

It took ZF nearly three years to develop the movement, and it's a masterpiece of sincerity! --The Jaeger-LeCoultre Geographie Q1428421, which realizes all the functions of the original and solves the problem of its thickness, has come to the market late and in a big way!

The left/right comparison is where you can see that ZF has done a great job from the dial to every little circle and literal face inside, and you can't tell the difference at all!

The contrast between the dial side face and the details on the crown logo are all perfectly in place, but one small detail is that the crown protrudes from the size of the original is a little bit longer.
