2 watches; one glued to my clipboard (UTC) the other on my wrist (local). Both analogue, dark face white hands, sweeping secondhand, quartz.
Anything else clutters the face and my brain.
Both £12 from Argos.
Spend your squeeze's money on a decent ANR headset, not watches/epaulettes/ray-bans/leather flight bags. The former will allow you to hear her nag, the latter is a free pass into the the tosser camp.
