cptzanzibarIt's much larger than the Seiko 5 - the b-dial flieger Seiko is a 37mm, this one is a 42mm watch.
The biggest turn off for the Orient Flights is a lack of seconds hacking (the seconds hand continues to run when you pull the crown out to set the date) - this was actually a critical feature back in the day, and was part of the original Luftwaffe specifications for this style. Without GPS or other forms of tracking, watches and chronometers were all bombing crews had to time bombing runs, making to-the-second timing pretty crucial to accuracy.
cptzanzibarI actually have that Seiko 5 that you are referring to. Its smaller than this watch, the crown is not screw down and also the movement is not made in Japan. Its actually made in Malaysia. The movement is noticeable not as smooth as my other Orient watches, but for half the price you really can't complain. Either way both are good for the money, just depends on your budget.
