Blancpain

Please can someone enlighten me on the movement which the Calibre 69F8 is based on ? 

This is the movement found in the Blancpain Leman Grand Date Flyback

Thanks in advance.

Greatly appreciated and Confirms my suspicion.

Nice photo of the movement, need to get meself another Blancpain...... its been months since the last one

Oliver ........ You are tipping me over !! The blued screws and Blancpain logo ....... Luv it ..... Luv it !!!

Comtemplating between the bracelet or leather strap. Or dare I say, even podered over a split chronograph !!

Although, must say am not overtly impressed with the deployant Blancpain makes. Does not give that re-assuring "snap" when put in place. 

Thanks again
