I was bitten by the midcentury Movado chronograph bug last summer and finally was able to land an example with a pulsations scale in the condition I was looking for. I searched a few times on here but couldn't find a thread dedicated to the M90/95, which seems a shame give the number of fantastic dials and cases they made in their heyday (I know there's one for the Super Subsea, but that's its own thing). Would be great to see the examples that OF members have as there's not a lot publicized about these. Here's mine. Also, here's the best reference on M95s that I know exists. I like the Fritz von Osterhausen Movado book but it doesn't have much technical detail. Hopefully someone will pull together a similar dataset for the M90 one day.
