<h2 class="section-header__title">
<span>Finding and Using Serial Numbers</span>
</h2>
<div class="section-header__body">Serial numbers are the most important identifiers for antique pocket watches, helping determine manufacturer, production date, and model specifics.</div>
The serial number is the key that unlocks your pocket watch’s history. Here’s how to locate and utilize this crucial piece of information:
Locating the Serial Number
On the Movement: The most reliable place to find a serial number is on the watch movement (the internal mechanism). This typically requires opening the case back.
Case Back Interior: Some watches have serial numbers stamped inside the case back, though these may refer to the case rather than the movement.
Dust Cover: On certain models, particularly those with hunting cases, the serial number may be found on the dust cover that protects the movement.
Dial Face: Though uncommon, some manufacturers placed serial numbers on the dial, usually near the 6 o’clock position.
What Serial Numbers Tell You
Once you’ve located the serial number, you can use it to determine:
Key Information from Serial Numbers
Manufacturer: The format and placement of the serial number often indicates who made the movement
Production Date: By consulting manufacturer production tables, you can pinpoint the year of manufacture
Model/Grade: Some manufacturers used serial number ranges for specific models or quality grades
Authenticity: Legitimate serial numbers that match the manufacturer’s records help confirm authenticity
The most comprehensive resource for American pocket watch serial number lookup is the Pocket Watch Database, which allows you to search records for major manufacturers like Elgin, Waltham, Hamilton, and Illinois.
For example, entering a serial number from an Elgin pocket watch will provide details about when it was manufactured, the specific model name, number of jewels, and other technical specifications that can help establish its value.

<span>Examining the Movement</span>
</h2>
<div class="section-header__body">The movement—the actual timekeeping mechanism—provides the most reliable information about your pocket watch’s age, quality, and maker.</div>
The movement is the heart of your pocket watch and typically the most valuable component. Here’s what to look for when examining a pocket watch movement:
Key Movement Characteristics
Jewel Count: Generally, the higher the jewel count, the higher the quality. Basic pocket watches may have 7 jewels, while high-grade pieces can have 23+ jewels.
Adjustment Markings: Premium watches were “adjusted” to maintain accuracy in different positions and temperatures. Look for markings like “Adjusted to 6 Positions” or “Adjusted to Temperature.”
Finishing Quality: High-grade movements feature decorative finishing such as damascening (swirled patterns), gold plating, or blued screws.
Plates and Bridges: The configuration of the bridges holding the gears can help identify the manufacturer and grade.
Escapement Type: Most antique pocket watches use lever escapements, but some high-end pieces feature more complex mechanisms like chronometers or tourbillons.
Identifying Fake or Altered Movements
Watch for these red flags that might indicate a fake or significantly altered movement:
Mismatched screws or components
Missing or added stamping
Inconsistent finishing quality
Serial numbers that don’t match manufacturer records
Signs of improper repair or replacement parts
<h2 class="section-header__title">
<span>Case Types and Materials</span>
</h2>
<div class="section-header__body">Watch cases varied widely in style, materials, and quality, each offering clues to the watch’s age and value.</div>
The case of an antique pocket watch can significantly affect its value and helps determine its age and intended market. Here are the main types and materials to be aware of:
Pocket Watch Case Styles
Open Face: Has no cover over the crystal, with the crown typically positioned at 12 o’clock.
Hunter Case: Features a spring-loaded cover that protects the crystal, with the crown typically at 3 o’clock.
Half-Hunter (Demi-Hunter): A hunter case with a small window or aperture in the cover to view the time without opening the lid.
Double Hunter: Opens from both front and back, allowing view of both the dial and movement.
Case Materials and Their Significance
Case Material Impact on Value
Solid Gold: 14K or 18K gold cases command significant premiums, often adding $1,000+ to value
Gold-Filled: Less valuable but still desirable, typically 1/20th gold by weight bonded to brass
Silver: Sterling silver (92.5% pure) cases are common and moderately valuable
Nickel or Base Metal: Least valuable but can be historically significant for workingman’s watches
Case Markings and Hallmarks
Case markings provide valuable information about the metal content and sometimes the case manufacturer:
American Gold-Filled: Look for markings like “Warranted 20 Years” or “Guaranteed 25 Years” indicating the quality of gold filling
European Hallmarks: British, Swiss, and other European cases feature hallmarks indicating metal purity, date, and location of assay
Manufacturer Marks: Companies like Keystone, Crescent, or Philadelphia Watch Case Co. often marked their cases
The relationship between case and movement is also important. Some watches left the factory as complete units, while others had movements and cases paired by jewelers at the time of sale. A matched original case and movement generally commands higher value than a “marriage” of unrelated components.
<h2 class="section-header__title">
<span>Railroad Grade Pocket Watches</span>
</h2>
<div class="section-header__body">Railroad watches represent a special category of pocket watches built to exacting standards for safety and precision.</div>
Railroad pocket watches hold particular interest for collectors and often command premium prices. After several tragic accidents were attributed to timepiece inaccuracy, American railroads established strict standards for the watches used by employees.
Key Characteristics of Railroad Watches
To qualify as a railroad grade pocket watch, a timepiece typically needed to meet these requirements:
Size: Usually 16 or 18 size (referring to the movement diameter)
Jewel Count: Minimum of 17 jewels, often more
Adjustments: Adjusted to at least 5 positions and temperature
Dial: White dial with bold black Arabic numerals and clear minute markers
Hands: Heavy, high-contrast black hands for legibility
Accuracy: Required to maintain accuracy within 30 seconds per week
Case: Usually open-face style for easier reading
Notable Railroad Grade Models
Some of the most sought-after railroad watches include:
Hamilton 992B and 950B
Illinois Bunn Special and Sangamo Special
Elgin B.W. Raymond and Veritas
Waltham Vanguard and Crescent Street
Ball Official Standard
These watches were built to exceptional standards of durability and precision, making them particularly valuable to collectors today. A railroad-approved watch in excellent condition can often command prices 2-3 times higher than a similar non-railroad model from the same manufacturer.
