More about Datograph 403.031 18K Rose Gold Black Dial COMPLETE "DUFOUR"

This is an 18K rose gold A. Lange & Sohne Datograph 403.031. It has a leather strap with a matching 18k rose gold tang buckle, and a scratch resistant sapphire crystal. There are rectangular pushbuttons for the chronograph and flyback function at 2 and 4 o'clock. There's a quick correction plunger on the edge of the case at 10 o'clock, and the chronograph's minute hand makes 1-minute jumps for an enhanced accuracy in reading the timing function. The precision flyback function of the chronograph instantly restarts the stopwatch to continuously time an event without needing to pause, reset, and restart. It has an exhibition sapphire display case back secured with 6 screws, and it's engraved with "A. LANGE & SOHNE – GLASHUTTE SA.," hallmarks, and a serial number. The solid 39mm diameter three-body case, rounded bezel, and downturned lugs are polished. The dial is black with rhodium-plated 18K gold sword hands with luminous inserts, and applied 18K rose gold Roman numeral hour and faceted baton indices. It has a gold rimmed double big date aperture window at 12 o'clock, and there are twin recessed silver subsidiary dials with black Arabic numerals, markers, and indicator hands, including a running small seconds register between 7 and 9 o'clock, and an instantaneous 30-minute chronograph totalizer is between 3 and 4 o'clock. There is a luminous white outer 60-second - 1/5 second track, and around the perimeter is a luminous white graduated pulsometer scale to 400 b.p.m. It's water resistant to 30 meters/100 feet, it has a 36-hour power reserve at full winding, and the 13mm thick case, dial, and movement are all signed. This A. Lange & Sohne Datograph 403.031 has a mechanical manual winding A. Lange & Sohne caliber L 951.1 column wheel chronograph movement. It's made of Glashütte 3/4 plate, with fausses cotes embellishment. It's constructed with 40 jewels, 405 components, a shock absorber mechanism, and includes 4 in screw-mounted gold châtons. It has a straight-line lever escapement, a monometallic balance that's adjusted to 5 positions. There is a self-compensating Breguet balance spring, a swan-neck micrometer regulator, and a hand-engraved balance bridge. The movement oscillates at 18,000 vph (2.5 Hz). The A. Lange & Sohne Datograph 403.031 watch was only produced for two years with the black dial, from 2003 to 2005.

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!
