Sturdily built watch and wrist band.  Extremely accurate (compares very favorably with my Swiss made watch costing much, much more)  BUT what is supposed to make this an aviator watch is the circular slide rule (used by me to compute ground speeds) and on this watch is totally useless!!  One scale is is on the outside of the dial face and adjustable, as it should be, the other is under the crystal, and  has no business whatsover of being there.  This mis-arrangement of scales always presents a very large parallax error, making calculations absolutely totally impossible to perform.  If you want to use this feature -DO NOT BUY THIS WATCH!
