The 950,950E & 952 take this spring. It is different from a regular 16s spring because the screw that holds down the bridge is located father down the bridge than a regular 16s Hamilton watch. The whip goes below the screw and on a regular spring the whip is above the screw head.
They are hard to find because no one has junk 950's in a parts drawer . You can use a regular spring but it will be on top of the screw head and most will never notice this...
