I am an amateur chess player and I am considering flying from the United States to Europe with the following chess clock:
I worry that the watch is a bit "scary looking". It's also quite tough and it's made of metal (aluminum), so I guess (my physics is a bit rusty) that it's like a Faraday cage with an almost empty space inside (basically, some small electronic components, some cables and two AA batteries). As such, I'm not sure how the equipment they use is displayed / recorded and if it could be of concern to operators.
Is it safe to assume that I will be allowed to take it in the cabin as checked baggage?
Or maybe I should take it with me to the airport already open so they can inspect what's inside? (There is a panel that you must unscrew to change the batteries or see what is inside, so a screwdriver is required).
