Cartier

Case No: 9526, case interior with London hallmarks, dated 1970-Calibre: Manual, cal. 841, 17 jewels

 

this date for the case 1970 should have the calibre 840 which is from 1960
as the calibre 841 did not come into production until 1973
the dimensions for both are the same=15.4x 13 x H 3.5mm and runs at 198000 vph
the calibre 846 came into production from 1975=15.2 x 13 x H 2.9mm and runs at 21600vph
putting the crash on a timing machine would help to clarify also measure it.
