Within a few short years, the 15-jewel standard watch, still accepted for entering service on many railroads, was an economic disaster.In 1894, Waltham, just after introducing the 17-jewel Vanguard Model '92, was forced to add upper and lower center jewels to the 15-jewel model `83's remaining in inventory, and engrave them to be 17-jewel watches in order to dispose of them (see Figure 17).6It was toward the later half of this decade that higher jeweled watches, those having 21 jewels or more, were introduced.It was also during this time that the majority of the more interesting and private label watches were built.

The 20th Century
By the first decade of the new century, 17-jewel watches were beginning to fade and 21-jewel (and higher) watches became firmly entrenched.Although 18-size watches were the industry workhorse during this period, new model 16-size watches began to appear in significant quantities.Hamilton's 992 was the most successful of these with over 100,000 sold in just a few short years.An increasingvariety of other 16-size standard watches were produced.During the early years of the twentieth century, despite Ball's rules for the Cleveland & Pittsburg(h) Division of the P.R.R. (see Figure 6), the move towards tighter requirements occurred.By 1908 the widely known and familiar requirements were almost universally in place.
Standard Requirements
(General - not from any specific set of rules)
Watches be:
American made 18 or 16 size
Fitted with17 or more jewels
Temperature compensated
Adjusted to 5 positions
Lever Set
Timed to +/- 30 sec/week
Fitted with a:
Double roller
Patented regulator
Steel escape wheel
Plain while dial (but 'Silvered' dials were allowed through the teens)
having:
Black Arabic numerals
Each minute delineated
Open face
Configured with the winding stem at 12 O'clock

(Which permitted the use of a hunting case movement in an open face case if it had a 'conversion dial' moving the stem to 12 o'clock and the seconds bit to 3 o'clock)

Watch
In addition to curtailing the acceptance (for watches newly entering service) of Roman dials, pendant-setting and hunting case watches, a near universal inclusion of two features occurred over the course of only a year or two around 1906-1908.One was that the marking 'Adjusted' gave way to 'Adjusted 5 Positions'.The other was that just about all new standard watches were fitted with a double roller.

The proliferation of grades from the various manufacturers during the first quarter of the 20th century has provided us with an overwhelming variety of standard watches to collect.Most of the watches that we see were built during this period.As for the 16-size watch, the 21-jewel model would be accepted for service for the next 30 years.Railroad watch requirements had become so uniform and stable by the mid-teens that South Bend was able to promote its famous 5-year insurance plan.The plan was that should any of its standard watches not be accepted due to a change in the requirements within five years of the date of purchase, South Bend would alter it to pass, or replace with one that would meet the requirements.
By the 1920's, the 18-size watch was falling out of favor, with fewer being made every year.During the 1930's 18-size were no longer permitted to enter service, and on some roads, were not permitted to remain in service.17-jewel watches also fell by the wayside, no longer being permitted on some roads.In both instances, these watches were no longer being made and so the rules were following popular tastes.It's significant to note that 17-jewel, 18-size watches, adjusted to three positions, continued to be grand fathered on some railroads as long as they met the 30 second per week requirement.

CB&Q RULE
Rules Governing Watch Inspection Service of This Company
April 1, 1949
2.The minimum standard of WATCHES NOW IN SERVICE is a grade equal to what is known among American Railroad Movements as 'NICKEL 17-JEWELS, BREGUET HAIRSPRING, PATENT REGULATOR, LEVER SET, ADJUSTED TO TEMPERATURE AND THREE POSITIONS,' that will run within a variation of thirty seconds per week.
POST WWII
Minimum serial numbers:In the 1940's, some railroads specified minimum serial numbers of the different watch grades for acceptance.This might have been due to the increasing use of the diesel-electric locomotive.These generated large magnetic fields and the anti-magnetic property of Elinvar, and its equivalent used by Waltham and Elgin, may have been significant.This is possible because the minimum serial numbers that were specified in the standards match up pretty closely with those of watches having these materials in their hairsprings.However, there is enough disparity that this might not have been the prime reason.

The post-war watches reduced down pretty quickly to the Waltham grade 1623 Vanguard, the Hamilton 992B (and Ball 999B) and the Elgin grade 571 B.W. Raymond.There were a few others, but hundreds upon hundreds of thousands of these three watches were built in the post war era.
In the mid-1950's Ball had standard watches made by the Record Watch Co.These were calibers 435, 435B and 435C.They were the first Swiss watches to see widespread use in the U.S. in fifty years.They're also significant for being just about the only standard pocket watch in service in the U.S. to have been fitted with an Incabloc (or any other) anti-shock system.Another Swiss watch, the Zenith Extra RR 56, was introduced into Canada in 1956.It was accepted on at least one U.S. railroad, the Alaska Railroad, as well.

Fig. 34:Zenith grade Extra R.R. 56 S/N 4,732,412 is shown here, its anti-magnetic as well as adjusted to temperature and 6 positions.

Hamilton outlasted both Elgin and Waltham by a number of years.In doing so, it managed to produce the last railroad standard pocket watch to be made in the U.S., the 992B.This watch was in continuous production from 1941 to 1969.At that time, all Hamilton manufacturing in the U.S. ceased.At over 500,000 made, the 992B had the second largest production quantity of U.S.-built standard pocket watches, exceeded only by the original 992.
Fig. 35:Hamilton's grade 992B was the last U.S.-built standard pocket watch, being in production until 1969.Its exemplified here by C 374366, continuously carried by the author for the last 25 years.The balance is obscured because the watch is running.
SUMMARY
So as has been discussed, railroad time service requirements preceded the American watch industry.Rules were in place as early as 1849 and by the mid-1850's a number of railroads had some form of program.Almost from the beginning, the key requirement was to keep time within 30 seconds per week.For thirty years, the 18-size adjusted 15-jewel watch was perfectly capable of meeting this requirement.It was driven from the market, not by changing rules, but by the 'jewel-count war' initiated by Hampden in 1891.
Single roller, pendant-set, hunting-case watches with Roman dials were still being allowed to enter service as late as 1906, but several years later, the rules almost uniformly precluded these features.The requirements really narrowed down by the end of the 1920's to 16-size 19-jewel minimum open-face, lever-set watches with Arabic dials.These rules remained in effect for another thirty years.
