The Vintage 1945 with blue dial for example is a super nice piece, but for whatever reasons which I also do not understand, it was hardly on my wrist.
The Sinn 103 ST C was a very recent addition, and it is nice, but it clearly has not the same perceived quality as lets say a GP or a Breguet Type XX. So no need to keep.
As for the Speedmaster, I am actually replacing the Super Luminova dial version with a Tritium dial.. So the replacement of the Speedie will be an addition for 2019.
Have a nice weekend,
Stefan
