It is a obvious mix out of the Doppelchronograph "TOP GUN" 3799 and the 3786 Doppelchronograph.
The only part taken from the TopGun model is the caseback, while the rest looks pretty much like the doppelchrono.
To become a good topgun rep it will need (besides the dimension) an engraving below the ten o' clock pusher with the TopGun-logo,
differtent second hands (red planes at the end) and titane crown and pushers.
to make a good doppelchrono rep, it will just need the right caseback, titane crown and pushers..
But still I like it: as long as you wear it, it will look good. Just don't show of that caseback...
