I own a Citizen skyhawk series, I've had it for 3 years.
The slide rule does come in quite useful during flight, can save scrabbling for the flight computer. After a while the information is easy to find on the face.
It's a nice watch, reliable and doesn't need looking after.
Is it a bit much for PPL? Possibly. The only in flight function I use is the stopwatch, but the good bit is that this runs with the time still visible and UTC visible too, whilst still having the slide rule available.
I'd still choose the same again, but I wouldn't worry about needing all of those functions, at PPL you can happily get away with something that just tells you the time!
