Apple seems to have updated its sitemap a bit ahead of schedule, as spotted by AllThingsHow. The URLs include references to the upcoming Apple Watch models. The new Apple Series 4 models will come in new sizes: 40 mm and 44 mm.

We have already got a glimpse of the new Watch thanks to our earlier leak. Apple will officially announce the new models later today. More below:

Apple measures watches by the height of the case. All watches to date have been 38mm and 42mm tall. These new watches represent a 2mm increase on both the smaller and larger sizes.

It appears that there are no ceramic Apple Watch Edition watches for this generation.

There are also mentions of various new sport band colors, as well as a new multicolor leather band and a gold stainless steel band.
