In 1869,Mr."J. C. Adams came to Springfield to interest local capitalists in the organization of a watch manufacturing company. The result was the organization of the Springfield Watch Company, with a capital of $100,000.00.InI\/Iay,1871,underthepresidencyofMr.j. T. Stuart, the Springfield Watch Company began the manu‐ facture of watch parts, and in 1872,the first watches were completed. These watches were 18size, full plate and key‐ wind. In 1873, the company had 125 employees and manufactured five move‐ ments per day. , In 1875, after the panic, a re‐organization was effected, the company being incorporatedasthe Illinois‐SpringfieldWatchCompany,withanauthorizedcapital of $250,000.00 of which $110,000.00. was paid in. . Under the presidency of General E. N. Bates, the company began the manu‐ facture of stem-wind movements for men, and both key-wind and stem-wind movements for women. In a very short time the production amounted to 100 movements per day, but the business was n o t successful and steadily continued to lose money, which necessitated a further re‐organization in 1878. The third company was organized and is still known as the Illinois Watch Com‐ pany, having been under practically the same management for over forty-five years. M r . Jacob Bunn was elected president in 1878, and continued to direct the business until his death in 1897, when he was succeeded by his son, M r . jacob Bunn, Jr. The policy adopted by the third management is maintained to date. In 1878, the Illinois Watch Company produced the first open-face watch made in the United States. , In 1879, it made the first nickel watch movements made in America. In 1896,itbroughtoutanewthinmodel,16size,whichbecameverypopular with railroad men everywhere. ' At the present time the output of the factory exceeds 800 watches per day, these being produced by m o r e than 1300 employees. There is perhaps no greater satisfaction to employer and employee alike, than tohaveservedlongandfaithfullytogether. Inthisconnectionitmightbeofinterest to know that although fifty‐three years have passed since the organization of the company, there are at the present time thirty‐one employees in active service, who started in the year 1880, or before. Of our 1350 employees, practically fifteen percent came with us twenty or moreyearsago. Thisisindeedaremarkablerecordandthecompanytakesgreat pleasure in thus testifying to their loyalty and efficient service. {brie‐353 ,{ u ,( 1914; the making of.cheap movements ' was discontinued and the company has since confined itself exclusively to the manufacture of the higher grades, having 17, 19,21and 23jewels. Consequently,the pros‐ pective purchaser will find illustrated and deScribed in this catalog, only complete watches and movements of the highest grade, ranging in price from $25.00 to $250.00. The extreme care taken in the selection of all materials that enter into the construction; the precautions exercised in the inspection of every operation; and above all the skill and superior workmanship entering into the manu‐ facture of these watches, is in itself an assur‐ ance of quality. Illinois watches are now pro‐ duced in many different grades and sizes. The 16 and 18 sizes, such as the “Bunn Special," “Sangamo Special," “Bunn” and ”A. Lincoln," are strong substantial move‐ m e n t s especially adapted to withstand the shocks and severe'service to which they are subjected by railroad men and others pur‐ suing the more strenuous occupations. The 12 size watches are particularly well adapted for less severe service, in the hands of professional and business men, students and others who do not subject their watches to such hard service. These watches are much thinner and smaller in diameter than the rail~ road grade movements, as for example the “Mini," “A. Lincoln,” “Marquis‐Autocrat" and the “Autocrat.” In wrist or bracelet watches, only one size movement is now manufactured, that being the 6/0 size, or 11 ligne, which is one inch in diameter. This m o v e m e n t is illustrated and fully described on page 19. During the present year an 18/0 size, rectangular movement, will be placed on the market. This small movement will be fully described and illustrated in a supplementary folder, at a later date. THE SANGAMO SPECIAL Bridge Model, is the highest grade 16 size railroad watch made. This m o v e m e n t was designed and built especially for railroad men and others who follow the more strenuous occupations, and who desire an exceptional watch of accuracy and dependability. THE BUNN SPECIAL Is the recognized standard of all railroad service. This is an extremely high grade, 21 or 23 jewel, 16 size railroad movement. It is notsoldbyusasacompletewatch,but can be fitted to any standard 16 size case of your own selection, from the stock of your retail jeweler. It is a dependable, durable and excellent timekeeper and is unquestion‐ ably the m o s t popular railroad watch made in America.

The company also has available a highly interesting, three reel motion picture film, entitled‐‐-“The Story of a Watch." This film was produced under the direction of the Bureau of Foreign and Domestic Commerce, United States Government, this department of the government having decided to co-operatewith representative American manufacturers in distributing approved films of industrial proc‐ esses throughout the United States and all parts of the world. The film visualizes the complete assembly of a watch, both by actual photography and tech‐ nicalanimateddrawings. Thishighlyinterest‐ ing picture can be secured, without charge, for technical or semi-technical schools, clubs, churches, Y. M. C. A.'s or other gatherings. The company pays all charges in connection with the transportation of the film. The only responsibility for those showing it, is to have next point. at,a moderate price.

These movements are high-grade and made for timekeeping purposes and n o t for orna‐ ments. A T I O N A L advertising campaigns have never been used to market Illinois watches These campaigns are very expensive and such expense obviously m u s t be added to the price of the product. The policy of the company has always been to make better watches, grade for grade, at a lower price to the consumer. ' Attractive display signs, descriptive folders, matrices and electrotypes are furnished, with‐ o u t charge, to retailjewelers upon request. Illinois watches are sold exclusively through long established and well known wholesale houses throughout the United States, no sales being made direct to dealers or individuals. Inquiries, however, are invited from both dealers and individuals, who will be given full information and referred to the nearest jobber handling these movements.

If the millions of timekeepers in the pockets of busy m e n and women were suddenly and permanently to stop, a demoralization would result that could n o t be obtained from the removal of any other device of modern civilization‐disorder and chaos would reign supreme. As gravitation keeps the great ma‐ chinery of the universe in harmonious working order, without variation, from sunrise to sunset, from century to century, so the ingenious device of m a n ‐ t h e watch‐keeps the great business and social systems of the civilized world in one moving unit of order.

' At first watches w e r e made by hand, and because of their intricate mechanism, a year was usually required to construct. a" single watch; From time to time the Swiss invented mechanical devices to expedite the hand work, until when watchmaking was introduced in America, much of the work was done by the Swiss on machines. At first the American watchmakers imported this machinery from Europe, until the Swiss government became alarmed at the possible loss of their business by new world competition and enacted laws to prohibit the sale of their machinery o u t of their own country. This enactment threw the inventive American upon his own resources‐ thepositionin whichhehasalwaysbeenstrong‐ est‐with the result that ways and means were gradually thought out and developed, which under other conditions than necessity would never have been evolved, the final result being the highest standard of efficiency in watchmaking ‐‐the American product. Since 1870 the slogan of the Illinois Watch Company has been quality rather than quantity. The standards set up by the Company at this early date have been i m ‐ proved upon by the inven‐ tion of ingenious devices in special machinery, until the watches made by the Illinois Watch Company are a rec‐ ognized standard of efficiency in America. rim which is made of brass, is welded to an inner r i m of steel, these t w o metals having a g r e a t difference in linear expansion due to changes in temperature. The rim'ofthe wheel iscut intwo places allowing a free movement of a portion of the rimto expandor contract away from, or toward the center of the wheel, consequently, when the temperature rises, the brass on the outside expands more than the steel, causing the r i m to bend in, thus placing a portion of the weight toward the center, resulting in a gain of time sufficient ~to compensate for the loss which would otherwise manifest itself. With falling temperature, just the reverse is t r u e w a portion of the weight of the r i m being thrown away from the center of the wheel, causing a loss in time sufficient to compensate for the error. ‘(0 HE balance with its hairspring is the most vital part of a watch. The weight of the balance in connection with the tension of the hairspring, provides a means of regulating and“ "maintaining“ a correct" and uniform measurement of time. Compensating "balance wheels are formed of t w o strips of dissimilar metal, usually of brass and steel‐the reason for this being to cor‐ rect an error caused by one of the laws of nature‐that of expansion and contraction. The effect. of changes in temperature onthe hairspring is somewhat different, however, as a fall in temperature causes the spring to shorten and become stiffer, which causes a g a i n , ‐ the reverse being t r u e with a rising temperature. .

Two of these screws are mean t i m e screws, which afford the m o s t reliable means of correcting the t i m e of a watch after being in service. Turn them toward the center and the watch goes faster,‐turn them from the center and the watch goes slower. The same kind of screws are used in the balance of the finest chronometers, and the same method is usedto regulatethem. As themainspringdrives the train of the watch the power is gradually released by the action of the escapement. The function of the balance wheel and hair‐ spring is to controlthemovementof theescape‐ m e n t so that the power from the mainspring willnotbetooquicklyreleased. Asthepower is released, the balance wheel moves alter‐ nately back and forth, approximately three‐ fourths of a revolution‐its movement in t u r n l I NDOUBTEDLY, m o s t persons who have looked i n t o a watch have noticed the peculiarly shaped wheel, having teeth n o t at all like the ordinary teeth of a gear wheel. This little wheel is known as the escape wheel and has a most important function to perform in a watch. The escapement takes its name from the fact that i t ‐ ‐ i n connection with the balance mech‐ anism‐allows the motion imparted to the train by the mainspring to escape, or r u n down, at exactly the proper rate. If the escapement were removed the mainspring would r u n down immediately and the watch would have no being controlled by the hairspring, one end of which is attached to the balance staff, the other to the balance bridge, thus limiting the degree of motion of the balance wheel. Breguet hairsprings are used exclusively in all Illinois watches. They are so called after an early watchmaker, who first conceived the idea of bending the outer coil of the spring in such a way that the entire spring will open and close uniformly as the balance oscillates, in‐ stead of tending to open and close more on one side than on the other, as an ordinary flat spiral spring would do. In addition, the use of the Breguet hairspring precludes the possi‐ bility of the coils catching in the regulator pins when the watch is jarred or dropped. There is more skilled labor and time spent ontheassemblyandadjustmentsoftheIllinois balance and hairspring, than is required to produce entirely, many of the timepieces on the market to‐day. timekeeping properties whatever. The escape wheel works in connection with the pallet, a small anchor-shaped steel lever, having at i t s ends peculiarly shaped jewels, so arranged that one of the jewels will alternately engage the teeth of the escape wheel, causing an oscillatingmotionofthepallet. The pallet is connected to a small lever called a fork. The power is imparted to the balance by the action of this fork on a jewel pin, set in a small steel disc on the balance staff, called the “roller." Each t i m e the balance receives an impulse from the fork and roller, it is returned after swinging through i t s proper angle, by the tension of the hairspring. gfietfamfiqwmodyhema/ HE SANGAMO SPECIAL is the highest grade 16‐size railroad watch made.

In replacingbarrelin move‐ _ " BOUT thirty years ago, the railroads of the country awoke to the fact that a large number of collisions and other accidents were due to the varying time kept by the watches used by their men. A time inspection was installed, making it compulsory for every man to have his watch inspected at regular intervals. These inspec‐ tions convinced the railroad officials of the necessity of presenting their difficulties to the watch manufacturers, who proposed supplying them with movements which were rated and adjusted so they would r u n uniformly in the hardest and m o s t exacting service. The first of these watches were adjusted to temperature and three positions and gave much better service than the former unadjusted watches, but as yet were n o t all that was de‐ sired. In their efforts to still further increase the timekeeping uniformity of their product, the watch manufacturers adjusted their move‐ ments to t w o more positions, making a total of five, as is n o w required by all railroads m a i n ‐ taining a time service. The increased number of adjustments added greatly to the efficiency, accuracy and u n i ‐ formity of the timekeeping of the watches, but it also added considerable to the cost. The ”Five Position Watches" were such an improvement over the “Three Position Watches" that this company decided to adjust their high‐grade railroad watches to “Six Positions" to assure reliable timekeepers re‐ gardless of the position in which they were placed. It requires from eight to twelve months to complete a high-grade watch, a large p a r t of this time being spent in adjusting the move‐ m e n t to the different positions, temperature and isochronism. ment, place the barrel, first in barrel bridge turning the barrel until main spring becomes hooked.
