Extensive Apple Watch display test: same PPI, color calibration, and color accuracy as the iPhone 6
DisplayMate specializes in performing extensive display tests, and with the Apple Watch being one of the most important products of the year, the display experts didn't pass on the opportunity to take the Apple wrist piece for a spin. The experts have tested the 42mm version of the Apple Watch with a sapphire glass cover, but we tend to believe that most of these conclusions will also apply to the 38mm versions.
On the 42mm Apple Watch, the OLED display measures about 1.53 inches across the diagonal and runs a resolution of 312 by 390 pixels at 326PPI and an aspect ratio of 4:5. The display experts found that the Apple Watch display is highly similar to the iPhone 6 display in areas such as density, artifact-free pixel reproduction, color reproduction, and color accuracy.
According to the report, Apple has opted to include a very aggressive automatic brightness system in order to reduce power consumption. Users can select the brightness as low, medium, or high, but there's no absolute manual control over the display brightness (as available on the iPhone 6, for example). While the automatic brightness system works well in low-light situations, in bright sunlight, the system translates in less-impressive measurements in key departments such as contrast ratios, color accuracy, and viewing angles.

Since the glass material is the only thing that differs between the three Apple Watch models, and not the display itself, this could mean that the best viewing experience is offered by the Apple Watch Sport thanks to its
