I have had my series 0 Apple Watch since mid 2016. I am getting ready for an upgrade to a series 4 and I initially planned to buy the stainless steel version, despite the higher price. I thought i could justify the high price for the stainless version with that it would last for a long time (safire crystal, scratches). But; after 2,5 years of use, the display on my series 0 watch is as shown on the attached images. It is noticeably dimmer on the most used parts of the display (skype logo at the top is much brighter), and the left part has a "dead" strip close to the edge (as you can see on the "45" of the watch face). Is this a problem Apple has solved for newer versions of the apple watch, or will the series 4 have the same problems i 2 years? What is your experience with the series 1, 2 or 3?
