A couple of observations after several days of using it:

- wouldn't activate while exercise app was running (actually paused) and the watch locked. Apple's guide says the device should go into Suica mode while locked so I asume it was exercise mode that blocked it from working.

- reload on the watch from a Wallet credit card worked without setting up an account in the Suica iPhone app. It took about 10 minutes after the credit card authorization went through and the watch said sucessful reload until the balance changed. Something to keep in mind if you're in a hurry

- accidentally triggered the IC reader while inserting a paper ticket into a turnstile with my watch hand. Only happened once so far and it was an exit gate. Still allowed me to exit but turned red until a station staffer reset the gate.

Overall, this has been great and so much easier not to keep track of a card. I doubt I'd go back to a physical one now.

ETA: reloaded again and card value wouldn't update either on my watch or in the app. A little concerned but it finally did several hours later after swiping on an IC pad (on a bus). I assume it also syncs the card at a reader and doesn't just store the value solely on the card?
