Sapphire glass has a very high transparency and has high scratch and wear resistance. In short, it's a much more functional work watch than it looks.

Dial and Hand Details

Let's take a closer look at the small details on the dial: the hour markers are made of metal rods, and the thickness of these rods is not the same; This design approach is really very successful. There is a metal Arabic numeral mark at position 12, just below it is the English inscription of Jaeger-LeCoultre; Its size and thickness are exactly the same as the original. Let me briefly touch on the functions of the three small dials on the dial: The small dial at position 3 is the needle date indicator, and the one at position 6 is the second time zone indicator. Additionally, a 24-hour display dial has been added to distinguish whether the second time zone is noon or midnight. The small dial at position 10 is the power reserve indicator. The hour and minute hands of the small dials are blue and extremely elegant. ZF's workmanship in details is very fine; The complex functions spread throughout the dial are quite suitable for male users who like challenging things.

Case and Body Workmanship

The side is made of stainless steel, polished and machined, looks very elegant and slim. There is a correction button at position 2 to adjust the small seconds dial at position 3. The crown in the center is used to set the watch normally and is embossed with Jaeger-LeCoultre's classic logo, with a gear pattern engraved around it. On the other hand, the crown at position 10 is used to adjust the time zone display. ZF Master Geographic is very rich in functionality; It is worth examining in detail.

The back has a visible case back design. The Japanese MIYOTA 9110 was used as the movement and was modified to imitate the Jaeger-LeCoultre Cal.939A/1 movement. The mechanism is stable and keeps time precisely; The functions are the same as the original, that is, the display mechanisms of the three small dials on the front work without any problems. Thanks to this visible case back, you can clearly watch the working process of the movement and, in a way, enjoy the viewing pleasure. The perimeter of the case back is also made of stainless steel; It gained a high shine through the polishing process. Additionally, different code numbers are engraved around the case back, and the letters are clearly engraved.

Strap, Buckle and Comfort

The strap of the ZF Master Geographic is made of imported black calfskin; It has a crocodile skin pattern printed on it and is sewn on both sides with black stitches, giving it a very high-end atmosphere. However, the calfskin strap can be a little hard at first, but it softens a little over time. The buckle is a stainless steel pin buckle; It's easy to put on and take off, and it doesn't pop open unexpectedly on your arm. In short, the style of this watch is not only limited to a classic atmosphere, but also has a strong mechanical character. Its appearance is simple, elegant and dignified; Its performance is stable.
