Portable Timekeepers


QUESTION: My grandfather left me the pocket watch he had received on his retirement. The watch is a Waltham. It still works but I’m not sure if it keeps good time. I already have a wristwatch and a smartphone, so I really don’t need this pocket watch. Is this watch collectible? If so, would it be a good idea for me to start a collection of them?

ANSWER: Your grandfather probably didn’t use his pocket watch very much. Businesses commonly gave gold pocket watches to members of their management staff upon their retirement. Before you do anything, you should take his watch to a watchmaker to have it checked and cleaned. Chances are, the watch is in like-new condition.

Pocket watches date back to the early 16th century. German locksmith Peter Henlein from Nuremburg invented the first to portable timepiece. Henlein also invented a spring-driven mechanism which made the personal timepiece possible. Spiral springs could be wound and uncoiled to move the hour hand of the clock. However, this mechanism was highly inaccurate because coiled springs don't unwind at a constant speed. But having a timepiece people could or wear on a chain, even if it was off by an hour or so, was a great improvement.

However, Henlein’s portable clock had a heavy drum-shaped brass box-like case, typically four or five inches wide and abut three inches thick, take up too much space in a person’s pouch. Unfortunately, pickpockets could easily snatch a pouch worn outside a person's clothing, so cautious people began to hide their pocket clock inside their clothing. This proved to be uncomfortable, so people began wearing their clocks on a  chain around their necks.

By 1653, tailors had begun sewing small pockets called "fobs," from the German word fuppe, into the waistband of breeches, in which to carry a watch, money, or other valuables. The fob, which means to cheat or misrepresent, was meant to prevent any  thief from easily removing a person's valuables.

By the end of the 18th Century, improvements in watchmaking resulted in watches that were thinner and more rounded. Tailors sewed smaller fob pockets into vests so that people could carry a watch attached to a chain.

Early pocket watches only had an hour hand. The dial wasn’t covered with glass, but usually had a hinged brass cover, often decoratively pierced with grillwork so the time could be read without opening. Watchmakers created movements of iron or steel, held together with tapered pins and wedges, until after 1550 when screws appeared. Many of the movements included striking or alarm mechanisms. The shape of the watches soon evolved into a rounded form called Nuremberg eggs. And even later in the century a trend for unusually shaped watches, shaped like books, animals, fruit, stars, flowers, insects, crosses, and even skulls, became popular. Beginning in 1610, a glass crystal covered the watch dials. To wind and set the watch, the owner opened the back and fitted a key to a square arbor and turned it.

The first solution to uneven unwinding came when watchmakers realized the spring uncoiled at a more constant pace when it wasn’t wound tightly. Watchmakers invented several ways to prevent this. The stackfreed was a cam with an additional spring that compensated for the main spring's changes in speed, and the fusee was a stop that prevented the spring from being wound too tightly. It was usually made of stiff hog bristle.

In 1675 several watchmakers discovered that a spiral spring attached to the balance greatly increased accuracy. Suddenly, watches reflected the correct time within minutes rather than being off by close to an hour. Until this time, watches had to be wound twice a day. A fourth wheel added to the movement decreased the winding required to once per day. Less than 100 years later, watchmakers added a hand to measure seconds. As years passed, people wanted calendars to mark the day, date and month, phases of the moon, as well as alarms, chimes and music.

Early pocket watches had no covering to protect the face or the hour hand. In the 18th century English watchmakers began creating gold and silver cases to slide the watch into to protect it. Watchmakers added glass crystals to protect the dial around 1610 but because they were translucent, people still had to remove them to read the time.

English watchmakers added jewels, usually second-rate gemstones in the 18th century as bearings in the watches to prevent friction and wear between metal parts. However, watchmakers from other countries didn’t adopt "jeweling" for nearly another 100 years. Today, the number of jewels a watch has is a sign of its quality and durability. Most pocket watches have between 7 and 21 jewels.

Pocket watches came in either of two types of cases—hunting or open-faced. Hunting case watches, popular during the 19th century, have a spring-hinged circular metal lid or cover, that closes over the watch-dial and crystal, protecting them from dust, scratches and other damage or debris, and opens when the owner pushes a button. Most antique hunter-case watches have the lid-hinges at the 9 o'clock position and the stem and crown of the watch at the 3 o'clock position. By 1900, the open face watch took over and hunting case watches became less commonplace. Watchmakers made cases of silver and gold. Many were gold-filled, with two thin sheets of gold on the outside around a thicker layer of brass. They also used a variety of silver-colored material, with names like silveride, usually nickel based.

Waltham pocket watches are very collectible. But because watch designs changed often in the early years, they sometimes made only a few of some models. A good example is the Waltham Model Appleton, a size 20, 18-carat gold watch with a rear key wind that had sold for $10,000. Because so many were made and in such variety, collectors can buy a pocket watch in running condition from as low as $100 US up to the $1000s if you want. Since most pocket watches don’t appreciate much in value, it’s possible to start a modest collection on a limited budget.

Keeping the Railroads on Time

 

QUESTION: My grandfather worked as a conductor on the Pennsylvania Railroad. When he died some years ago, I inherited his pocket watch. For a long time, I thought it was just another old pocket watch. Then a friend, who’s father was a watch repairman, told me it was a special kind of pocket watch—a railroad pocket watch. Other than that, he didn’t know why it was so special. Can you give me some insight into antique and vintage railroad watches?

ANSWER: The answer to your question goes back to the last decade of the 19th century. On April 19, 1891, a train engineer's watch stopped for four minutes and then started again. This temporary mechanical failure resulted in a train wreck that killed nine people in Kipton, Ohio. The railroads set up a commission to create new standards for the railroad pocket watch, to be used by all railroads.

A railroad grade pocket watch was a watch that a particular railroad approved for use by its engineers and conductors. 

The Railroad Commission required every engineer to have his pocket watch inspected regularly and to submit a certificate stating its reliability to his supervisors. When there was only one track for trains barreling in both directions, being on time was a matter of life and death. As the Kipton wreck proved, an engineer's railroad watch being off by as little as four minutes could mean disaster.

The new standards dictated that a railroad pocket watch had to have at least 15 jewels. After 1886, the number of jewels increased. They also had to be accurate to within 30 seconds per week, as well as have a white dial—although the railroads allowed silvered dials until around 1910—with black Arabic numbers for each minute delineated; adjust to five positions, and be temperature compensated.

Although a pocket watch’s size, ranging from 0 to 23, didn’t refer to its width or length or casing but rather to the size of its movement, to meet railroad requirements, a watch's movement had to be either a size 16 (1 7/10 inches) or a size 18 (1 23/30inches).

Manufacturers sometimes broke the rules and made railroad watches with Roman numerals. The last two requirements were critical. As the early watchmakers discovered, not only could cold and heat cause a watch’s movement to slow or speed up, but so did the watch's position. Imagine a conductor trying to carry a watch in one position all the time, especially while working on a train. Railroad watches had to stand up to constant abuse from the jarring and swaying of early trains.

Contrary to common belief, there were many regulations in place before railroad officials commissioned Webb C. Ball to create a standard set of railroad watch qualifiers in the 1890’s. 

Before then, and until the entire railroad industry accepted Ball’s standards, different railroads had different standards for the watches their crews used. One line might have had a list of accepted makes and models while another might have only listed necessary features or timekeeping performance thresholds. This made evaluating older watches as railroad grade a difficult task, because a watch may have met the standards of one company but not another. 

As the rail industry grew in the United States, the number of active trains grew with it. In order to use a particular track efficiently, railroads had to create time schedules identifying when each section of that track was safe to use. The timekeeping accuracy of the engineer’s and conductor’s watches was crucial if two trains were moving in opposite directions. If one of the two engineers’ or conductors’ watches were keeping bad time, a collision could occur. Railroad watches became known as “standard” watches because they met a railroad’s standard of timekeeping.

Companies like Waltham, Elgin, and Hamilton made the “best” railroad watches after 1900. An important part of standard watch regulations included service intervals and testing, but there was also a list of features that almost all railroad watches shared. 

The most prominent feature of 1900’s railroad watches was their lever actuated setting mechanisms–commonly referred to as "lever-set.". Most watches were put in time-setting mode by pulling the crown, or winding knob, away from the watch, then pushing the crown back towards the watch to return to winding mode—referred to as "pendant-set."

A lever-set mechanism required the user to remove the bezel of the watch—the convex glass protecting the dial---and engage a lever to place the watch in setting mode. This tedious process of removing the bezel had a very important purpose. It ensured that the time on the watch was never accidentally changed by catching the winding knob on a pocket or any number of other unintentional situations.

Another important feature of railroad watches was their big, bold, black, Arabic numerals on highly contrasting white enamel dials with large bold hands. This feature made telling the time as clear and easy as possible while creating a distinctive and functional railroad watch design.

Mechanically speaking, almost all 1900’s railroad watches shared a number of performance and reliability enhancing features. Most had a fixed regulator to avoid timekeeping variation from impact, a double roller balance wheel to avoid going out of action, 19 or more jewels to reduce friction and increase consistency of the gear train, timekeeping adjustment in five or more positions to make sure the watch kept accurate time regardless of its orientation, and adjustment for temperature to ensure accuracy in a variety of climates. Many railroad watches had solid gold or gold plated gear trains and jewel settings to reduce the effects of magnetism as well as reduce tarnishing, and later watches had features such as magnetically resistant balance wheels.

Although there were many other fine pocket watches made in America, the quality of the workmanship made them second only to chronometers for being precise—they had to be.
