That's fairly normal for older or more basic digital watches - they don't know anything about the year, so every four years you have to manually set them back the 29th of February. I think that people see this as a bug says something about changing expectations. Pre-digital watches generally didn't know about months either, so required manual date adjustment every other month. The framing of this manual adjustment as a bug feels like it comes from our experience of dealing with computer software all the time.
