How to Find Info About Your Pocket Watch

The Pocket Watch Database has compiled data covering the major American pocket watch manufacturers and created an easy way to find information using the serial number on the watch movement. Here are a few tips to find information about your pocket watch:

  1. Always input the serial number from the pocket watch movement (the "mechanism" of the watch).
  2. Never use the serial number from the case or any other part.
  3. Always select the correct manufacturer, which is usually stamped on the watch movement or dial.
  4. If the manufacturer is not listed on the site, you may have a "private label" watch or it may not be American-made.
  5. If the serial number includes a letter, enter it along with the number when using the lookup feature.
  6. Many pocket watch case backs screw off. Others may require a dull wide blade to pry or pop the cover. Be careful not to scratch or damage the movement.
  7. Consider uploading images of your watch by creating a collection account on the website. This is compeltely free and assists in promoting research in American horology.
  8. Understand that many companies did not keep accurate or complete records. As a result, information displayed on this site may have inaccuracies. This is to be expected, and we have included an option to report inaccurate information on the result pages so the database can be continually improved.

Special prices apply where the manufacture is special for a n y particular piece also for parts of dis‐ continued watches when no longer a stock item. The quality of watch parts used in the construction of Waltham Watches is the best that is made in the world. All material sold through our Material Department is of the same high‐grade quality and finish, and is made to factory standards that a r e closer, m o r e ac‐ curate, and more dependable than material made by outsiders. Reliable watchmakers use GENUINE staffs, jewels, mainsprings and other repair parts. When a new train bridge, barrel bridge or balance cock is wanted the remaining part of the movement should be sent to insure perfect fitting. Pillar or lower plates are not sup‐ plied either as material or fitted to movements. If a n y retailer or repairer is unable to obtain from his jobber GENUINE Waltham Mate‐ rial in models shown in this catalogue, we will consider it a favor to be informed of the fact, and will at once see that the material is supplied. » Whenever a sample is submitted y o u will "Speed U p " service if y o u will also submit the Movement Number.

TRADE MARK‐ CLEANING OF FINISHED WATCH DIALS AND HANDS Our dials are lacquered for protection before the printing is applied. Therefore, finished dials can be cleaned only by such methods as do not remove the printing. Such cleaners as benzol, benzine, carbon tetrachloride, trichlorethylene and patented watch cleaners tend to soften and remove the printing. Benzol, carbon tetrachloride and cyanide cleaners also soften and remove the lacquer. Small scratches on the dials produced by careless handling allow cleaning solutions to flow underneath the lacquer with the result that the lacquer m a y peel. The use of a buff stick in cleaning hands m a y cause the lacquer to crack at the sharp edges of the hands and later this lacquer will peel. Under no circumstances should dials or hands be put into washing machines. Dials and hands m a y be cleaned by brushing with a dry camels hair brush or with a dry, soft jeweler‘s brush. If more vig‐ orous cleaning is necessary the brush should be moistened with ethyl alcohol (grain alcohol). Another method of cleaning dials and hands is to brush them with a camels hair or soft jeweler's brush dipped in cold soapy water. The soap should then be thoroughly rinsed off with clean water after which the dials should be dipped into ethyl alcohol and dried immediately in sawdust. A number of tests performed on dials six months old as well as some just taken from the Dial Department showed that the dials could be cleaned by the proper procedure without causing the lacquer to peel.

PIONEER RESILIENT MAINSPRINGS These Mainsprings contain less metal than the ordinary spring. The pat‐ ented process, employed in tempering, develops the strength and elasticity, giving them the pulling power of a much thicker spring. They are made for all sizes of movements manufactured by the Waltham Watch Company. UNIT EACH 3~ FEATURE SPRING ; PROTECTS SEPARATE t x I t a SPRING ,,tA,km AND ADDS A CONVENIENCE Insist on and use Genuine Pioneer Mainsprings. Waltham Quality is assurance of the best. NOTE TABLES GIVING STANDARD DIMENSIONS OF MAINSPRINGS ON PAGE 29 28 MAINSPRING-S The following is a list of “Pioneer” Resilient Mainsprings, giving catalogue numbers, and the minimum and maximum width and thickness which have been decided upon by the Waltham Watch Company as the best adapted for each spring. The strength of a “Pioneer" spring, determined by the thickness, is denoted in this schedule in thousandths of a centimeter. To illustrate: If a ”Pioneer" Mainspring No. 2205 is wanted weak, medium or strong, it should he ordered .021 cm. for weak; .022 cm. for medium; or .0221/2 cm. for strong. The standard length of springs is given in both centimeters and inches.

If the screw measures .65 for example, we find that .65 in the column of diameters of threads corresponds to No. 17 tap, for which the tap drill should measure .54. The only threads which we are unable to identity by measuring their diameters are No. 7 and No. 13, but in this instance the difference in pitch is sufficient to show at a glance in comparing one with the other. 31 «33 59 «33 Bridgeictenter Second ~ 1 637 .83 Bridge,Train ---------- 637 .83 15 .1 ..

We Show in this catalog only a few patterns of each size Bar, but we have in stock, or are prepared to manufacture, some 2000 patterns of Bars for old and the most modern cases. The size of the square of a Bar is determined by the watch companies and is standardized by the size of the hole in the winding parts. While repairers sometimesrefer to threads on Bars by sizes as 165 or Os, as a matter of fact there is no standardsize thread that can be applied to any particular size of watch. . Waltham Bars and Sleeves are made with the same care and precision that characterizes the manufacture of genuine VValtham Watch parts, and since modern casing demands the very best in Bars and Sleeves, our scientifically built material is by far the best to buy and use for repair work. To insure repairers of obtaining just what they require, it is best to send sample showing pattern of Bar, to be matched, to the material jobber or to the factory. ‐ 28054 28190 28196 28222 28192 28198 28193 28194 28245 28247 28078 28249 28250 28251 28121 am 28096 ',~ AMAM mm .
