My watch reboots random, is this a HW or SW issue?

Hello and welcome to Apple Support Communities Sleijkert,

We see that you're having an issue with your Apple Watch restarting unexpectedly. We know that it is important to have your Apple Watch working properly, and we'd be happy to isolate this issue with you.

Let's start by having you restart the Apple Watch and the iPhone that it is paired with, then test to see if the issue remains.

How to restart your Apple Watch

Restart your iPhone

If the issue remains, unpair your Apple Watch and then test again.

Unpair and erase your Apple Watch

If the issue persists after going through these steps, respond back with the answers to the following questions.

1. Are you running the latest version of software on both devices?
2. When the Apple Watch restarts, does it fully restart or does it get stuck on the Apple logo?
3. Has there been any physical or liquid damage to the watch that you're aware of?

We look forward to hearing back from you.
