A. Lange & Söhne Langematik Perpetual Calendar 18kt Yellow Gold with Gorgeous Silver Dial and Applied Roman Numeral Hour Markers, Large Double Window Date Display Located at the Top of the Dial, Small Seconds Sub-Dial with Inset Moonphase Window Located at the Bottom of the Dial, Day of Week & 24-Hour Indicator (AM/PM) Located at the 9 O'Clock Position Sub-Dial, Month Indicated by the Subdial at the 3 O'Clock Position - With Inset Leap Year Indicator. In Addition, this watch has a Zero reset seconds hand which resets the seconds hand to Zero when you pull out the crown to adjust the time. This makes it extremely easy to synchronize the watch to perfection. Sapphire crystals in front and on the caseback for viewing the Gorgeous Lange Caliber L922.1 Sax-O-Mat Movement. The automatic caliber features a solid 21k gold micro-rotor with a platinum segment, 43 Jewels, hand embellishment, and hand regulation.

The caliber L922.1 "Sax-O-Mat" movement has a Glasshute ¾ German silver plate with fausses cotes decoration, 43 jewels, a hand-engraved balance bridge, and a monometallic balance adjusted to 5 positions. There is a self-compensating flat balance spring, a shock absorber, and a straight-line lever escapement. It has a 21K gold, bi-directional micro-rotor with a platinum segment, a swan-neck micrometer regulator, and the dial, case, and movement are all signed. It is an elegant 10mm thin, and looking into the transparent case-back one cannot help but marvel at how much those tiny mechanisms accomplish.

The movement also makes use of Lange's Proprietary Sax-o-Mat technology. While the dial and case are unadulterated by the form of excess, the movement is a work of art literally. The balance cock is hand engraved and hand decorated, meaning each and every movement is a singular work of art - This masterpiece is fitted on a dark black crocodile leather strap with a tange buckle. Case measures 38.5mm x 10.7mm thick.
