Hi.



A 1100 wrench is a professional tool that shrinks the crystal applying balanced pressure to removed it without damaging it. Technically the part is a precision crystal compressor tool consisting in a metal wrench and adaptable rings. Here how it looks like (the one below is a 1200 - only the diameter is different - shape is the same) :

i have a longines five - ginko_97.jpg


Once crystal is out the movement comes out through the front of the case, the back does not open and it is all in one piece

Don't try to open the watch by yourself. you will damage the case. The watch is still worth over $500. If you are located in USA I suggest contacting the professional repair below. If you are located elsewhere find a local Longines repairer or a vintage watch repairer.

Please, don't try to open the watch cause it will damage the case.
Have it repaired or restored by a certified watchmaker. Special tools will be needed exclusively for watchmakers.
The way to get through it is on the glass.

The back you are trying to remove is a screw on back, there is a special tool that you can purchase on ebay called a case opener, it fits into the slots and is rotated anti-clockwise. But be aware there are different sizes, you can hunt for the right one for your particular watch or buy a universal that will fit most types.

You will need to get a special type of spanner tool to remove the back cover. I would check with a jewerly store or a store like radio shack often has these tools so they can sell batteries. Thank you.

I have a wittnauer wrist watch , serial number 520556. How old is it and what model.


Not every watchmaker can be as renowned for its movements as LeCoultre or as admired for its designs as Cartier. Some watchmakers get their start simply by seeing an opportunity and seizing it.

Such is the story of Albert Wittnauer, who came to America from Switzerland in 1872 at the age of 16. Even as a youth, Wittnauer knew watchmaking, which made him a useful addition to his brother-in-law J. Eugene Robert's Swiss-watch importing business. Over the next few years, two more of Wittnauer's younger brothers and a sister would join him in New York City, forming the nucleus of Robert's, and then Wittnauer's, company.

The opportunity Wittnauer identified was not technological. Rather, it was market driven. Wittnauer saw an opening for a less-expensive Swiss pocket watch in the United States. Since Robert was already importing watches from Switzerland, including Longines, it was not a large leap to add a Wittnauer-branded model to the company's offerings. The watches sold well. By 1885, Albert was running the company, importingchronographs and repeaters, and by 1890 the firm was renamed the A. Wittnauer Company.

While Wittnauer got its start with an economy model, it quickly moved into more rarefied terrain, creating highly sophisticated chronometers. The company's breakthrough came in 1907, when Wittnauer supplied a pair of watches to the Navy, which was testing its aviation capabilities. Perhaps because of this very early alignment with the budding aviation industry, Wittnauer watches would be worn by such notable explorers as Roald Amundsen and Richard E. Byrd, as well as aviators from Amelia Earhart to Wiley Post.

After Albert's death in 1916, his sister, Martha, took the firm's reins. During World War I, Wittnauer supplied new military wristwatches and precision navigational devices to American Expeditionary Forces and an aircraft clock to the forerunner of the U.S. Army Air Corps. Around the same time, Wittnauer introduced its All-Proof wristwatch-the anti-magnetic watch was water and shock proof-to the U.S. market.

In the 1920s, Wittnauer produced wristwatches that were technologically advanced as well as aesthetically beautiful. The lugs of Wittnauer wristwatches were one of many details its designers did not take for granted, and the shapes of the faces varied from squares and rectangles to circles and hexagons, as in the gold Grasshopper.

Aviation watches, though, remained a prime focus. In 1927, Wittnauer and Longines both worked with a U.S. Navy officer named Philip Van Horn Weems, whose design for a Second Setting Watch included an inner, rotating dial. The aviator would move the dial until he heard a time-tone on his radio, thus capturing any deviations from Greenwich Civil Time.

Another influence on Wittnauer timepieces of this era was Wittnauer watchmaker John Heinmuller, who was the official timekeeper of the U.S. National Aeronautical Association and became one of the country's leading authorities on U.S. air mail stamps. Because of all this attention to navigation wristwatches and devices, Clarence D. Chamberlin and Charles A. Levine used Wittnauer chronometers for their 1927 trans-Atlantic flight (they flew two weeks after Lindbergh) and Charles Collyer and John Henry Mears used two Wittnauers in 1928 when they famously raced the moon around the earth-they did it in 24 days, beating the moon by 72 hours.

More aviators, Howard Hughes among them, wore Wittnauers in the 1930s, but the company struggled during the Depression, prompting its sale, in 1936, to a pearl manufacturer, who renamed the company Longines-Wittnauer. World War II provided Wittnauer with contracts for Weems wristwatches, as well as compasses and timers, and after the war it produced wristwatches that utilized technologies created for the conflict.

In the 1950s, Wittnauer turned some of its resources to fashionable dress wristwatches. As in years past, the lugs of Wittnauer wristwatches such as the Revue were almost as important to the design as the face. By now the company was offering slimmer self-winding watches than it had in the past, and in 1957 it released its first electric wristwatch.

Westinghouse bought Longines-Wittnauer in 1969, in 1994 Longines was sold to Omega owner SMH, and in 2001 Wittnauer was sold again to Bulova.

Dear Sirs! My new (1month) Longines automatic watch hastens each day (and night) four seconds.Model L4.721.2 Is it normal or I have to turn to the laboratoty to fix the problem?! Thanks a lot Iosif


An automatic watch that gains 4 seconds in a day is good.A new Rolex is rated at 5 seconds per day so 4 seconds is well within what you can expect for your watch.As a tip when the watch is off the wrist place on its side,gravity slows the operation of the watch just a fraction.This is called positional error and may help.

I WOULD LIKE TO ITS TRUE VALUE


mcdevito75 here, Many factors figure in the value of a watch, Of course you have a NAME watch Longines which helps a great deal, First, if the hands are thick, the watch is before 1969, if they are thin, anywhere after 1969, Original strap or band conts, a good, good replacement band is ok. the appearance of the watch, no scratches opr buffing, scrapping on the caseing, no scratches or cracks in the crystal (glass) of course being vintage there will be some evidence of age, and lastly time keeping, if your Longines works well keeps time all day, I estmate it"s value, anywhere from $125.00--------- $200.00. You can also check a small watch repair shop in your area or jewelery shop, they will usually give a rough estmate of value for free.

If I buy a Longines 10K gold filled watch, what is the difference between that and solid 10K gold? and is there a big difference in the price of 10K gold filled per gramme and solid


Gold filled is simply a very thin layer applied to the base metal case and will wear off over time. Solid 10K gold is an alloy that is mixed with gold throughout and will always retain it's color and never wear off. The solid 10K gold case contains a lot more gold than then the gold filled version and will cost more up front. However, the gold filled case will look awful in a year or two while the solid 10K case will last as long as you keep the watch and beyond.

How do i set an older longines automatic admiral watch to the correct date and day


You can get instructions from their web site but if your watch is really old, then it seems unlikely that any of the instructions there are for your watch.

However, since watches tend to have similar features (although not the modern electronic types), a basic modern watch probably operate in the same manner.

Go to "www.longines.com/watches/instructions" and have a look at the range of instructions there to see if they are any help.

If nothing useful is found look at the "official retailers" to see if there is a local shop that can help you.

How do i change the date on a 1960's longines Admiral?


If you pull out crown gently, you will notice there are two clicks (positions), not just one. So the first click, when crown is not pulled out fully, is exactly for day/date adjustment. If you pull the crown further out, watch is in hand adjustment mode. Try it carefully and you will find out the right position.
Rate me, please.

Face almost unreadable;can only adjust winding back;stops intermittently.


Hi Murbilpov,

thank you for using fixya, you have a very fine piece of jewelry. it appears that your watch needs cleaning right on the knob and adjust mechanism. as per a service document from longines, a possible build-up or a broken first gear may cause this issue.

you may refer to their official statement when it comes to cleaning and having the watch repaired.

1) Where should I send a Longines watch that needs to be repaired, adjusted or serviced?If your Longines watch needs to be repaired, adjusted or serviced, werecommend that you bring or send it (well padded and by registereddelivery in the latter case) to your nearest Longines authorizedservice centre. You will find its address in your guarantee booklet oron our website in the Customer Service section.
2) Is the repair of a Longines watch that is more than 20 years old still possible?Yes, we still repair vintage watches at our head workshop in St-Imier.
However, without having the watch to hand, it is impossible for us tojudge its state and to know if all the necessary spare parts for therepair are still available.
Therefore, we kindly suggest that you send your watch via the nearest Longines authorized servicecentre to the Longines head office in Switzerland. Upon receipt andafter analysis of your watch, we will send you our comments and a priceestimate for the repair of your watch.
3) How often do you recommend having a maintenance service carried out on a Longines watch?We would like to draw your attention to the fact that a watch used daily is running 24 hours a day, 7 days a week non-stop.
The frequency of the maintenance service depends on the type of watch, the climate and the care taken by the watch wearer.
In general, it is necessary to have your watch controlled andserviced at least once every 4 - 5 years, just like any other precisemechanical device. This guarantees the reliability and rate precisionof your watch.
4) Which operations are included in a complete maintenance service?The following operations should be included in the price of a complete maintenance service:
– complete dismantling of the movement, cleaning, oiling, reassembling, regulating and the checking of functions;
– repair or replacement of movement components that are either worn or faulty;
–replacement of the following parts: glass, crown, push-pieces, sealsand battery if a quartz calibre (parts included in the price of theservice, with the exception of shaped mineral glasses and sapphirecrystals);
– restoration of the water-resistance (if a water-resistant model);
– refurbishing of the case or bracelet (two-tone, gold-plated and PVD-coated cases and bracelets, cleaning only);
The above service standards are only valid for the Longines head office in Switzerland.
5) Which operations are included in a partial maintenance service?The following operations should be included in the price of a partial maintenance service:
– during each partial basic repair, Longines undertakes to check theregulation of the movement and replace the glass (if necessary), thepipe, the crown, the push-pieces, the seals and the battery in the caseof a quartz movement (these parts are included in the price, with theexception of shaped mineral glasses, sapphire crystals, and restorationservices carried out on the dial, case and bracelet. Parts made out ofnoble metals will be invoiced separately);
– restoration of the water-resistance (if a water-resistant model) and cleaning of the case and bracelet;
Any repair that necessitates the replacement of a part, or any servicementioned in point 7 automatically involves a partial basic service.
The above service standards are only valid for the Longines head office in Switzerland.

Hope this helps, should you have other questions, please do not hesitate to let me know.
