Are screen protectors and bumpers really necessary? Just curious what the general consensus is on this. I hear about how rugged it is supposed to be compared to the regular Apple Watch. I love the look of the Ultra and would hate to cover it up with an ugly bumper. I rocked the Series 4 without any protection for 5 years and it held up well and I work with my hands in an industrial setting. There are a few hairline scratches in the glass, but nothing major. Just curious how others feel about the topic.
