The 1972 model has 3 "crowns" all the others have 2 "crowns" as best I could find on this site searching for "Wrist Alarm" a 1972. The picture displayed is almost identical to this watch except for the text unther the numera 6. So I thought it was from the 70's but the previous owner said it was from the 50's.
I don't know how to open the case - the previous owner said it was 17 jewels with a 12-B caliber movement and that it was from the 50's.
Hope this helps...
