Fortis Flieger GMT Automatic 596.10.148 Calibre ETA 2893-2

the new Fortis crown is an entirely different construction, and doesn't screw down

the watch still doesn't run reliably - I take it apart again

the tube that holds the fourth wheel sits too low, and the fourth wheel can sometimes touch the third wheel

tube now sitting correctly

the proof is in the pudding - the watch now has a higher amplitude, and maintains it.
