A Reason To Clockwatch

Standard Viva Advice Number 62: don’t check the time during the viva because doing so will only be a distraction.

A clear exception is to do this because you need to: maybe you need to take breaks for specific medical reasons or to help you have a fair viva process.

That would be a good reason to keep an eye on the time. If you’re concerned about losing focus by clockwatching then perhaps make sure your examiners know about your need and ask them to be responsible for encouraging those breaks.

More broadly: there’s a lot of really good, well-meaning and often-helpful viva advice that might not apply to you. Listen to advice, take what you need and find your own way to get ready and pass your viva.
