I understand that space travel affects time, but why would it affect the mechanisms of a watch? doesn’t it just go tiktik u know?

The key thing is that *everything* observes a different “speed” of time, yourself included, not just the watch. You wouldn’t realize that the watch is moving faster, and neither does the watch. To you and everything that is around you everything appears as normal. It’s not the watch that is behaving differently, but time itself. It’s only when you return to earth and compare watches do you realize the difference.
