Probably. The Apple Watch locks when removed from the wrist, and required subsequent authentication before it can be used for payments. There's minimal risk here.

I dont own one. Does it look when removed? Is unlocking required for all, or can i disable it?

I also don't own one, but my understanding is that:

- a passcode is required to use features like Apple Pay

- the watch can be configured such that it only has to be unlocked once, until it is removed from the wrist/rebooted/manually locked

>> "- a passcode is required to use features like Apple Pay"

Not true. You just double tap the side button and can use Apple Pay. The way it secures itself is that as soon as you remove it from your wrist it locks and requires a passcode. You can't do anything with it until you enter the passcode.

That's what I mean, sorry. You can't configure Apple Pay without having set up a passcode; wrist detection allows you to skip entering the passcode so long as the watch hasn't been removed.

It locks automatically when you remove it from your wrist.

As soon as the Apple Watch is taken off your wrist it has to be unlocked with the passcode again, I believe.

I think this is fair but I also struggle to think of a situation where my Mac and my Apple Watch get stolen and I'm not aware of it in time to lock my accounts.

maybe you're aware, but not able to do something. Backpack with Macbook, Watch and Phone stolen. What would you do?

Macbook sure, phone maybe, but why would your watch be in your backpack?

Also, the watch automatically enters a locked state when its off your wrist.

Because the robber said "your Apple gadgets or your life!", and carried them away in the bag.

Or, perhaps because you put in in the bag to go through airport security, and the bag was handed to someone else.

Your watch would be locked, being off your wrist.

Your phone is locked because its got TouchID enabled and a passcode.

Your laptop is locked as well. Getting in here requires you unlock something first, even if you have everything. The stronger security devices provide authentication to the weaker ones.

I'd imagine you would need to unlock the Apple watch before it would unlock the computer.

Indeed. It's actually an interesting cycle: you can unlock the iPhone with your thumb, which unlocks your Watch if on your wrist, which unlocks your Mac if nearby.

Any problem in computer science can be solved with another level of indirection.
