What a difference a year makes: Apple Series 4 versus Series 3

If upgrading old Apple to the new 4 series and planning the first direct comparison.

The new crown is thinner than the old version. This difference, coupled with haptic feedback, rather disappoints returning to Series 3.

Another difference is that the side buttons are perfectly aligned with the series 4 body and the series 3 side buttons draw a considerable amount.

Overall, the new series 4 will be …
