Usually when an unannounced device leaks out, it's because a source leaked it or something similar. Today's leak of the Samsung Galaxy Watch comes from a different source.
Samsung briefly listed the Galaxy Watch on its own website today. A listing on Samsung's U.S. website showed the 42mm Rose Gold version of the unannounced Galaxy Watch, complete with a model number of SM-R810NZDAXAR.
The listing has since been pulled from Samsung's website. When it was live, clicking the link would take you to a dead page, meaning that there was no spec or pricing information to be had.
The Galaxy Watch has leaked several times by now, so this latest leak isn't quite as big a deal as it might've been a month or two ago. It is still notable, though, because this information appeared directly on Samsung's website, which is just about as official as you can get without an actual announcement from Samsung itself. Now we just have to wait for the watch to actually be announced so that we can find out what makes it tick.
