Clock watchers

Has anyone installed any type of clock. If so pros & cons please.
Since times flies & I may forget to pick up the kids!!!!!!!!!!!!

Cheap digital watch strapped to the bar, or with a double-sided adhesive pad on the top yoke (remove strap).

If I'm on a long journey then the satnav tells me the time.

I had one of these  watch   strapped around top yolk too the left of my ignition, worked a treat,  it was still on there when I sold it too, it just displays a blank screen until you press on it and it then displays the time in bright red never had a problem reading it in different light conditions. And at £2.50 with free delivery you can't go wrong

I've an Oxford analogue clock on the FZR, it's discreetly positioned & is a god send, there is a digital version too but I personally think they look out of place on a bike with analogue clocks.
