<p>I was wondering if you are allowed to use a timer on act and sat
Because watch is allowed and all lot of watches have timers.</p>
<p>If your watch has a timer, then you can use it, but it must be silent. No beeping allowed. A separate stand-alone timer is prohibited.</p>
<p>^ Yep. I opened my watch and modded it so it wouldn’t make any beeping sounds.</p>
