I'm a private pilot working towards his instrument, commercial, and multi-engine certificates, and I love my watch.  There are two gripes I have:

1) The band, even on the stainless, sucks.  I'm not hard on my watch at all, and the forward side (I wear it on my left wrist) is full of wear marks and scratches from only resting on tables as I sit and read or do work.  I'm pretty unhappy with that fact, and think that for a $[...] watch the band should be more scratch resistant.  I haven't had this problem with other metal band watches.

2) There is no light.  You wouldn't think it would take much to add two small LED's and an extra button for a light for night use.  The "glow in the dark" hands stop working after a half hour-ish of darkness and you can't read anything without some light source.  I haven't found this to be too much trouble for night flying since I have an overhead red light that I can hold the watch up to, but it's inconvenient and potentially hazardous since your taking your attention off of flying for that much longer.  For a true aviator's watch you'd think they'd have thought this one through.

Gripes aside it's an excellent watch.  I researched long and hard for a good aviators watch, and I settled on this one.  While others may have better features (i.e. better looking, different layout, etc.) this one had the best of most of what I was looking for.  I wanted something that I could use as my timer, a backup E6B, my zulu time (although I don't use it much and find myself doing the math in my head just as quick), my watch...and for future use if I become a professional pilot I can keep track of time with time zones.  The Eco-drive is an excellent feature that although I haven't had it long enough to know how well it really works, in theory it is excellent for the environment, and for piece of mind knowing that you'll never need to worry about a dead watch at and inconvenient time.  Also, the alarm clock feature is excellent.  There are three separate alarms that are easy to set up, turn on and off, and use.  I don't use that in the airplane, but I do use it for work and it is awesome; not too noisy, and not too quiet, but I doubt it's audible in the airplane.  I don't think there's much more to say besides if you're looking for an inexpensive REAL aviator's watch this is about the cheapest you'll find, and it will have all the features and then some that you'd ever want.

Citizen, replace my band with something that doesn't scuff up so easy and this watch gets 5 stars from me.
