They often are listed by different names, but most of them are the Weishi 1000. That’s the one I have and it’s easy to use and works great.
Yeah, you can usually just search for "Timegrapher 1000". They are usually between $150 and $200. It is one of the best purchases I have made as far as watch tools and toys go.
I bought an MTG 3000 like the following on eBay. It was less back then (they seem to have inflated in price). it’s simple to use and gives repeatable results. Note: it’s a great tool for someone “curious” about watch timing. Not a replacement for accurate timing devices used by professional watchmakers. Only get one if you won’t obsess over what you find, as it could ruin a good watch by exposing what is normally hidden.
