Finally got around to having a dry run with the original roller that came with the watch and what should be a genuine nos staff that does match the movement caliber specified as an AS 554. No go at all , the bottom of the big table sits directly on top of the fork. So it seems the complete balance assembly has been modified to fit a staff that was made to fit inbetween the plate and cock. Unless I've gone wrong somewhere and identified the movement wrong and the staff should be a different one. Problem is the original staff broke in two and is very poorly made making it difficult to measure. Looks like this will have to be shelved until another 554 comes my way, or if anyone has one and can verify the staff measurements for me. Now i think about it I do have the stem, i could use that it check the caliber 🤔 -

Cheers Ross, as stated I'm really chuffed for you. -
Oh dear, terms! Sorry for the confusion. So it's 'run' when it's fully inserted and "hand set" when it's pulled out to the click. That's very helpful, thanks! -
