This site is continually evolving with new manufacturers added and updates to existing model databases. 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. Recent additions have been tools to date and identify Apple devices as well as Samsung Galaxy and Sony Xperia mobile phones. Aimed at collectors, sellers, dealers and eBayers, it now covers vintage or antique Rolex, Tissot, Timex, Elgin, Casio, Citizen and Omega watches as well as Gibson, Fender and CF Martin guitars, Roland and Boss (which includes all the old analogue gear and Boss pedals), Kawai and 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. It is now one of the most comprehensive sets of serial number decoders on the internet. Since then it has expanded to cover my other interests and collectible vintage equipment in general. This project started back in 2012 when I wrote a basic tool to cross reference the serial numbers and the movements on my personal vintage Seiko watch collection. Welcome to .uk, a collection of serial number date decoders and tools.
