Welcome to, a collection of serial number date decoders and tools. This project started when I wrote a basic tool to cross reference the serial numbers and the movements on my personal vintage watch collection. Since then it has expanded to cover my other interests and collectable vintage equipment in general.

It is now one of the most comprehensive sets of serial number decoders on the internet. Aimed at collectors, sellers, dealers and eBayers, it now covers vintage or antique watches such as Rolex, Tissot, Timex, Elgin and Omega as well as Gibson, Fender and CF Martin guitars, Roland and Boss (which includes all the old analogue gear and Boss pedals), Yamaha pianos, DOD and Ibanez guitar pedals, Hot Wheels diecast models and some electronic component dating tools useful for dating vintage guitars, pedals and synthesizers. Having a date for a collectible can help you check its authenticity and spot a fake, it can help you with a valuation and can also help you fetch more when selling items on eBay.
This site is continually evolving with new manufacturers added and updates to existing model databases .
