Just flipped my speedy 3590 cuz I wasn't happy with the case as the whole watch was polished and I didn't see the brushed/polished facades or really crips lines. Been looking at 3590 or 145.022 with nicer cases.

Is it normal to see a 69 year case with a 70-71 caliber in it or is it most likely a movement swap.

 

According to speedmaster101 ( http://speedmaster101.com/145-022-69/ )

Calibre 861
Serial Range:

2842 0xxx – 3162 9xxx

30-31m is fine for a -69

 

@momosono @padders thanks appreciate the confirmation. learnt a lot from buying my first piece and have to be much more critical in choosing the watch there seems to be so much more once you get It in your hands
