One of the most common questions for collectors is “how old is my watch?” Unfortunately, there’s no single way to determine the age of a given vintage watch. Even watches from the same brand often have different ways of determining age depending on the era in which they were made. Luckily we live in the age of the Internet and also have access to some great books, so there is hope.

Below is a list of dating-related resources that I’ve been able to find, sorted by brand name. It’s far (far, far, far) from exhaustive, so please send me anything new I should add or changes I should make in the feedback box below.

General Resources

The Ranfft Pink Pages for Timepieces: Dr. Roland Ranfft has created one of the watch collecting world’s great resources and time-sinks. Here you can find technical and date information on literally thousands of movements, including details such as movement size, hand size, and lists of other variations in the same movement family. There’s also information on a multitude of different watches as well.

Another great source is the Pocket Watch Database. Don’t let the name fool you, while the site focuses heavily on content about pocket watches, the movement database includes information about many early wristwatch movements, including those for Elgin, Illinois, Hamilton, and Waltham models.

Bulova Search for your watch by movement, model, serial number or date code. Extensive gallery of photos to help you identify your watch visually. Members of the site regularly help people identify “unknown” models as well. Also includes photos of vintage advertising and catalogs to help you learn more about watches in your collection.

One quick tip with Bulova is that since 1949 they’ve used a letter-plus-number date code on the case back. So L5 would be 1955 and M7 would be 1967. WatchOPhiliia has a detailed article on other ways to identify the ages of various Bulova models. You’ll find a wealth of other great Bulova information there as well.


 The Elgin Watch Serial Number database makes it simple to find the age of your watch. Just enter the number, and it responds with whatever information it has, includes years of manufacture, size, grade, how many were made, and more.


Everything you need to know is here at Gruen wasn’t as consistent in how it numbered its watches and movements and used cases from a number of manufacturers over the years, so dating them can take a bit of effort. This site walks Gruen fans through several techniques (case style number, movement number, etc.) for identifying and finding the age of their watches. If you prefer your data on paper, Mike Barnett’s Gruen Watch Model Identification Guides are excellent resources.


In addition to the Pocket Watch Database listed above, you can also find lists of Hamilton serial numbers at After the 1960s, Hamilton stopped producing its own movements, so the Ranfft database above can be more useful. There’s also Bruce Shawkey’s Hamilton Wristwatches: A Reference Guide for anyone who likes turning actual pages. It’s a great book.

While not specifically a way to date your watch, Dan Keefe’s is also a world-class resource. Dan has restored countless Hamilton watches and describes the process for each on his blog, complete with detailed photos.


The Pocket Watch Database is a good place to start, but if you really want to know something about your watch, The Illinois Watch and Its Hamilton Years by Fred Friedberg is the be-all, end-all source. The book set covers everything you could ever want to know about Illinois wristwatches, far beyond just age. 


Like many high-end watchmakers who have withstood the tests of time relatively intact, Omega offers owners of its products the ability to contact customer service to learn more about their watches, including when they were manufactured. As of this writing, the service was temporarily closed for an upgrade, but customers could supply their email address to be notified when extract requests would be accepted again.

For basic date-by-serial-number information, has a table of Omega numbers and dates.


I don’t collect Rolex, but people who do often refer to as a reliable place to go for the classic Swiss timepieces. The site also includes a database of manufacturing dates by serial number. You can also take your watch to an authorized dealer to learn more about it, including whether it’s actually a Rolex.

Watching the World Go By, A Tick at a Time

Why yet another watch blog? When I started collecting just a short time ago, I found lots of great information on collecting watches all over the web. But there was no one place for a new collector who wasn't interested in high-end brands and models. This site is dedicated to consolidating what I've learned, and will continue to learn, in one place. At the same time, I hope to connect some people to the sources I find most valuable.
