Just imagine if you had a digital watch today. What a conversation starter. You would be the envy of the office.
And when lady spies like Madeline Smith noticed your ultra-modern Pulsar time computer and tried to snog you, then you’d be able to act bored and casually press your button behind her back like Roger Moore in You Only Live Twice
You could use the watch’s powerful electromagnet to undo her zip. And then later you would be arrested and shamed.
