I still have my old Citizen Sky hawk pilot watch from about 20 years ago. Nothing wrong with it except it didn't have a light.
Yes I used the circular slide rule a couple of times.
Since my wrist is a bit skinny I don't really like the mega chunky so called pilot watches (eg like my old one). I now use a Casio G-ms. It's pretty good really.
The features I like.
Solar powered face to recharge the battery.
Large clear hands.
Digital section for different time zones, alarms etc.
Metal bars to stop the glass from being scratched up.
Metal band.
Light. Although, the digital bit isn't lit. That's something I'd change.
Water resistant and tough.
It doesn't really look like a poser pilot's watch!
If it was made out of titanium it would be even cooler but probably three times the price!
