A Few Facts About IWC's History:

1868: How it all started

n 1868, an American by the name of Florentine Ariosto Jones made the brave decision to found a watch factory in Switzerland from where he planned to supply the USA with movements. Switzerland was a low-wage country back then and had a ready supply of skilled labour for the watchmaking industry (mainly manual work carried out by people working from their homes). In French-speaking Switzerland Jones met with fierce resistance because, people feared for their jobs and the work they did at home.

In 1850 the town of Schaffhausen was in grave danger of missing the bus to the Industrial Age. It was at this stage that watch manufacturer and industrialist Johann Heinrich Moser stepped in and did the region a huge service. As a pioneer of "white coal", he built Schaffhausen's first hydroelectric plant and laid the cornerstone for future industrialization. He probably met F.A. Jones in Le Locle and showed a great interest in his plans. And so it was that the foundations were laid for the first and only watch manufacturers in north-Eastern Switzerland: the INTERNATIONAL WATCH CO. in Schaffhausen.

1869: The eventful early years

"With the object of combining all the excellence of the American system of mechanism with the more skilful hand labor of the Swiss, we have established our Watch Factory at Schaffusen, Switzerland."
F.A. Jones rented the first factory premises in an industrial building owned by J.H. Moser in Rheinstrasse. Very soon he had to rent further rooms in the "Oberhaus", one of the oldest buildings in Schaffhausen. By 1874 plans were already being made for a new factory. A site was purchased from Moser's hydroelectric company directly adjacent to the banks of the Rhine, the "Baumgarten", as it was called. Schaffhausen architect G. Meyer won the order to design and build the factory and about a year later, in spring 1875, the construction work was completed. At that point 196 people were working in the 45-meter-long factory, which could accommodate up to 300 workplaces.The IWC story goes on.

1880: Beginning of the Rauschenbach era

Johann Rauschenbach-Vogel, Chief Executive Officer and a machine manufacturer from Schaffhausen, took over the INTERNATIONALE UHRENFABRIK on 17 February 1880. This change marked the beginning of the story of INTERNATIONAL WATCH CO., which would last almost one hundred years and four generations, a family-owned company that would be known under various names.

Only a year after the sale, Johannes Rauschenbach died. His son, Johannes Rauschenbach-Schenk, was 25 years old when he took over the UHRENFABRIK VON J. RAUSCHENBACH and ran it successfully until his own death on 2 March 1905.

Another significant role on the way to the company's lasting success was played by Urs Haenggi from Nunningen in the canton of Solothurn. He had got to know the watch business in French-speaking Switzerland and France; in 1883 he joined IWC and stayed with the company for 52 years. He got factory operations up and running smoothly and acquired new customers. He was also responsible for warding off the danger of the factory passing into other hands "in the interest of the noble Rauschenbach family".

Technician Johann Vogel from Wangen on the Aare in Solothurn likewise played an important role as technical director. He designed and developed IWC calibres until 1919.

1905: E.J.Homberger

After the death of J. Rauschenbach-Schenk in 1905, his wife, two daughters and their husbands, Ernst Jakob Homberger (director of G. Fischer AG in Schaffhausen) and Dr. Carl Gustav Jung (psychologist and psychiatrist), took over the watch factory as an open trading company by the name of the UHRENFABRIK VON J. RAUSCHENBACH'S ERBEN. E.J. Homberger was the only authorized signatory, Haenggi and Vogel were directors.

Following the death of his father-in-law, Ernst Jakob Homberger had a considerable influence on the Schaffhausen watchmaking company's affairs and guided it through one of the most turbulent epochs in Europe's history. Just before the world economic crisis, he took over as sole proprietor and renamed the company UHRENFABRIK VON ERNST HOMBERGER-RAUSCHENBACH, formerly INTERNATIONAL WATCH CO. His contribution was honoured in 1952, when he was awarded an honorary doctorate by the University of St. Gallen. He died in 1955, aged 85 years.

During the period just before and after the First World War, E.J. Homberger devoted himself to devising and setting up social institutions. He extended the living quarters for factory employees and established a fund for widows and orphans. In 1929, the name of the fund was changed to the J.Rauschenbach Foundation and in 1949 he founded the Watch Company Welfare Foundation.

1944: The mistaken bombing of IWC

On 1 April 1 1944, as a result of a fatal error, Schaffhausen was bombed by the American airforce. The watch factory was hit by a bomb which, fortunately, failed to detonate after crashing through the rafters. The flames from incendiaries exploding nearby penetrated the building through the broken windows but were extinguished by the company's own fire brigade.

This timepiece features an elegant new GOLD & BLACK enameled steel DIAL has been professionally updated and now is in excellent condition. It is featuring a 60 minute outer track border, gold enameled main Roman numerals, gold steel Breguet-style hands and a recessed sub-seconds dial with 60 second outer chapter and “sweep” steel seconds hand. Signed International Watch Co in gold enameled lettering below the XII and further signed SCHAFFHAUSEN.

It is a registered design model that features a three piece GOLD PLATED case that provides with glass cover of back lid. This watch was converted from pocket watch. GOLD PLATED case, new custom made, fantastic, build specially for this excellent IWC movement. The lugs are in great condition while the Pumpkin-style winding crown is in very good shape and operates properly. The case has MINERAL glass on the front and back side. The case is signed International Watch Co – SCHAFFHAUSEN on the lateral bezel.

Peeking inside via the glass lid I find a spotless manual wind gold plated high-grade mechanism with FIVE RAISED & SCREVED ROSE GOLD JEWEL SETTINGS and SWAN NECK MICROMETER REGULATOR & BLUE BREGUET BALANCE SPRING. The movement is stumped importer's mark S&Co, for STAUFFER & Son and movement serial number #687,089, dating the watch to 1918 as per company production records. Also are signed PEERLESS – SWISS MADE – H6 – +55231. The movement is a Lip. c.52 – 19lig. H6 caliber.

This beautiful wristwatch has the pristine Original movement in an excellent status which was very well saved, considering age of this watch. Mechanism has been recently serviced to ensure it winds and sets smoothly while keeping great, accurate time.

Historical Data - Stauffer & Co.

Many watches from Schaffhausen bear a signature of the firm which sold them on the watch face. In some cases IWC movements were also made with a dealer signature. The best known of these, and the most commonly found today, is that of Stauffer, Son & Co., established in 1830. From 1894 the London branch of this Anglo-Swiss firm was supplied with watches from Schaffhausen, and from 1898 the movements of these bore the mark 'S & Co.' under the crown with the words 'peerless' and 'Swiss made'.

Until the mid-1930s Stauffer & Co. retained its monopoly over the IWC watch brand. Thereafter they were sold under their original trade name, as they had been prior to 1898.

"Stauffer, Son & Co was founded in 1830 in Chaux de Fonds, Switzerland. By 1860 they were trading as a partnership (Jules Stauffer and Francis Claude) at 12 Old Jewry Chambers, London EC. Stauffer subsequently retired with his place being taken by Charles Nicolet. They were listed in Directories at this period as wholesale watch manufacturers and importers. Claude retired in 1874 leaving Nicolet to take control of the firm. The Watchmaker Jeweller and Silversmith reported on the watches, chromometers and repeating watches exhibited by them at the Inventions Exhibition of 1885. They moved to 13 Charterhouse Street, Holborn, London EC in 1887."

This is a “NAIL SET” watch so you don’t pull the crown out to set the time. Instead, you press the little button near the crown IN and then move the crown to set the hands, releasing the button once you’re finished. It’s easy, so don’t worry about getting the hang of it!

It is fitted on a new 20mm black alligator style genuine leather strap with golden steel buckle that is vintage style and goes great with this wonderful watch.

Diameter (with 53.00 mm
Diameter (without crown): 47.00 mm
Watch crystal diameter: 43.00 13.00 mm

This cleaned, oiled and regulated antique watch winds and sets very smoothly while keeping very good, accurate time.

Because of the vintage nature of the watch I cannot guarantee its absolute time keeping accuracy even if they are in good running condition and in some rare occasions may require additional adjustment.

Always an EXTRA FINE watches at a Price!!!

If you like rare, antique, unique and collectible vintage wristwatches or pocket watches (or just enjoy learning about all the different watch makers and models) I suggest you bookmark this page or add me to your "Favorite Sellers" list. I always have beautiful pristine timepieces for sale ending Monday. Now on for 7 Years! Recommendations for the owner of vintage watches: - All Antique watches are mechanical. Many repairs will not be cheap, as most likely they will require replacement of non-standard parts (unlike most late model watches). - Antique watches should not be beaten or dropped - because repairs may be expensive. - Antique watches are generally NOT waterproof. This is because waterproofing was not in general production until the middle of the 20th century for most watches. Therefore you should protect your antique watch from exposure to moisture. - If your watch becomes wet it should be dried off quickly. Carefully open all covers and use a hair drier to blow dry the movement, dial, covers, crown. This will reduce the amount of rust. - If your watch becomes wet with any kind of salt water you should immediately immerse or spray your watch with fresh (no-salt) water to remove all the salt from the works before drying the watch completely. Any salt left in the watch will combine with moisture in the air to rust metal components of the movement, case etc. - Winding any mechanical watch tight may break the mainspring. If you can avoid it do not wind the watch hard. - When adjusting the hands of your watch, move them in a clockwise direction only. Counter-clockwise adjustments may damage the movement. - If you must adjust counter-clockwise make it for small adjustments only (i.e. for minutes, NOT hours). - Be careful and gentle when adjusting the movement speed (faster or slower). Don't make sharp movements, and don't touch other components in the movement especially the pendulum mechanism. - Every 2-3 years it is necessary to service and oil vintage watches. - If the watch is dirty - allow the watch to run down, don't wind it again until you have it serviced by a qualified watch repair expert. Dust will absorb and remove important lubricants and cause the movement pieces to wear down. - To clean the case, dial and crystal you should use a cloth that does NOT leave fibers as these may get caught up in the movement. Check with your Watch repair expert to get an appropriate cloth. - Keep your antiques watch away from magnets. Strong magnetic fields may affect the accuracy of your watch since some vintage watches were made with iron based components in the movement. - Most Cases and Covers are fine components and will not handle abuse well. The watch should not be shaken, beaten, or stressed. - Antique watches generally experience an error of up to 5-7 minutes a day. Any accuracy of +- 5 minutes is very good.
