In reply to Nice watch, can you confirm… by neetstuf-4-u
Senator 'J' in the ad is for the top watch.
The second watch in the ad is the Senator 'G' and is a match to this watch. The linebooks that we have all state this as the Senator 'C' as ref#32727. The pricelists that we have show 32727 goes with the 'G' variant. I don't find any ads showing this as the 'C'; and this 'G' is found in ads through 1958 (including the ad above).
The watch in question is 1959 model; and Linebook 136 for 1959 (and 139/140 for 1960) now show this model as the 'P' variant ('O' black dial). There is no longer a 32727 listed in the linebooks past 1958.
For 1959, this model would be the Senator 'P' (noting the hand style is not a match)
LB136 1959
I'm going with Ken's in depth research on this one. This watch was previously the "G", through 1958. In 1959, this watch became
variant "P", replacing "G" possibly based on band change. Based on case and movement date, this particular example classifies as
Senator "P"., noting possible swapped hands.
