More about Langematik Perpetual Calendar 310.021 18K Yellow Gold FULL SET

This is an 18K yellow gold A. Lange & Sohne Langematik Perpetual calendar 310.021. It is the first self-winding wristwatch ever made with a perpetual calendar function, a double window outsize date, and a zero-reset mechanism. A single push of the corrector on the side of the case at 10 o'clock advances all calendar functions simultaneously by one day. This self-winding timepiece has four subsidiary dials, one at 9 o'clock for the days of the week that includes a 24-hour day/night indicator, another at three o'clock for the month and within that is a leap year dial. The moonphase indicator is at 6 o'clock. The silver dial has 18K yellow gold alpha hands and applied Roman numerals. The leather strap also has an 18K gold buckle. It has a three-body, solid, brushed and polished case with a rounded bezel and a transparent sapphire case-back with 6 screws. 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 it's also produced in platinum. Lange only included the perpetual calendar with the moonphase indicator in five important pocket watches between 1887 and 1931, with the dream being of an outsize date watch that was also perpetual. They presented the horological world with this incredible timepiece in the late 1990's. It has since been discontinued/upgraded with slight changes. This watch is a definitive example of how this first and still finest of German precision watchmakers set the standards in horology in 1845.

Testimonials

I have been dealing with European Watch Company for over ten years, and have purchased several wrist watches, including IWC, Patek Philippe, Rolex, and Jaeger-LeCoultre. They were not only fairly priced but arrived in like-new condition, fully warranted by European Watch Company. This company has an attentive, knowledgeable staff, a large inventory, and is a genuine pleasure to deal with.

Just completed my 7th transaction with EWC and for the 7th time the transaction was smooth, flawless and quick. Joshua is quick to respond to any e-mails and answer any questions. Ashley knows how to complete the necessary paperwork to avoid any delays at Customs as I am located in Canada and all paperwork needs to be completed perfectly which she is an expert at. You only want to deal with the best and the team at EWC is the best. There is a Yiddish word to describe the people at EWC and that word is mensches which translates to people of integrity and honour.

After a lengthy search I located the Patek Philippe I desired at EWC, but the decision to make a high dollar purchase over the internet was a difficult one. Through numerous emails with Justin and looking at reviews of EWC I made the decision to proceed and I am now ECSTATIC. The watch is exactly as described and pictured. It was perfectly packaged and shipped FedEx overnight. My watch collection now includes the watch I have been seeking for over a year.In summary, you can deal with the EWC staff with confidence. They are professional, honest and you will receive a quality watch which will put a smile on your face.

I live in San Francisco but the EWC website is the first place I check once I get an impulse for a particular watch. EWC's website is cozy and feels like home. I enjoy the photos, presentation, description and historical notes of each item and really like their next day delivery, so I stay loyal to them. Sometimes I must wait awhile for a watch to become available but can usually find anything I want. Then there are the watches you never knew you wanted until you see them here.

Dear EWC, I have just completed my very first purchase with your company: a mint Lange Datograph. Robert was extremely help throughout the process with the item delivered nicely packed to my Hong Kong address within days. The condition of the watch was absolutely mint as described and has exceeded my expectations, even under a loupe! I will be a return customer in no time. Well done!
