Pulsar is made by Seiko, so i assume the MOD were just enticed by the cheaper model of the same watch. Just think Audi A3 and Skoda Oktavia....
That comparison would imply that the Pulsar is a better watch than the Seiko, which as we all know isn't the case.
Own a Seiko Flightmaster Kinetic, best watch I've had, but the Citizen Skyhawk Titanium was V nice (close second!). Almost perfect time-keeping, but face scratched very easily.
Another great watch for flying is the Casio Pro-Trek series. Ginagorous digits, perfect for flying and indestructible. Mine gives me QFE (+/- 1 Mb) which can be handy on det.
