Gosh, I hope you don't have that cell phone on IN FLIGHT... And it must look really weird strapped to your wrist. Kinda like old Star Trek episodes, possibly?
Anyway... As for what you NEED... I agree with your CFI, actually.
1- Sunglasses, to me, are a necessity. At least when it's sunny! Cuts down on glare and eye fatigue. It has nothing to do with "protecting your eyesight" (whoever heard of someone going from 20/20 to 20/50 because of sunlight??), it's about seeing better in bright light and reducing eye STRAIN.
2- Watch... Absolutely. I know you're only a student, but the clocks in most trainers are either inaccurate or are only right twice a day (think about it!). The nine dollar Armitron, the 35 dollar Timex Expedition, and the $2800 Breitling B-1 all do the same thing, which is tell accurate time, show the date, have a stopwatch, and show a second time zone. The Citizen Navihawk series seems to be an epidemic, with probably 1 out of 6 pilots I see having one. It runs somewhere over $200, but it won't do anything that the Timex Expedition will do... And the Timex has a backlight. I am partial to analog hands and digital secondary displays, so the G-Shock is out. But... That's just me.
3- Headset. My GOD, if you don't have a headset you're a looney. Good ones protect better, and if you really have money to burn, ANC headsets are better still. I keep coming back to the David Clarks, though, which I've used for the overwhelming majority of my hours (the Litespeed headband keeps breaking!). I won't say "spare no expense" on the headset, but a $300 DC actually IS three times as good as the $100 Flightcom. Trust me on this.
All of the above is just my experience and blatant bias.
