With less than five hours to go until Apple’s event rumours and supposed leaks are rife and now AllThingsHow have claimed they managed to extract the new Series 4 Apple Watch sizes from the URLs referencing the upcoming products, the URLs were supposedly found in an updated sitemap for the Apple website.

The new watch models should come in 40mm and 44m, compared to the current 38mm and 42mm sizes for existing models. The new sizes include the Silver, Space Gray and Gold color options, as well as both GPS and GPS + Cellular configurations.

The new leaks support Analyst Ming-Chi Kuo said back in July that the new Series 4 models would be about 39.9mm and 45.2mm wide in terms of case size and have about 15% larger display with rounded corners. The current 38mm watches are 33.3mm wide while 42mm models are 35.9mm wide.
