Welcome to PocketCalculatorShow.com's Nerd Watch Museum. Our collection spans hundreds of models, dozens of manufacturers and infinite gadgetry. Since your hosts are of the LCD generation, rather than LED, liquid crystal display models have been the focus of our collecting. Many LCD timepieces played an important role in the evolution of digital wristwear, and we are striving to present as many as possible in our virtual museum. If you've got an unusual model that would make a great addition, please let us know! We've got many available for purchase too, so please check out our For Sale page. NEWS: We always have vintage digital watches for sale! Whew...we've completed exhaustive effort to display all of Seiko's Computer watches! Wow, Paul visited Seiko's museum in Tokyo! Check out some pictures from the visit! The Nerd Watch Message Board is up and running! Visit an online community of LCD wristwatch collectors to socialize and share information about digital watches. Hey, we've finally upgraded the site! Our hope is to provide faster access to even more classic LCD watch information and pictures. We appreciate your feedback. |
