Thanks for that information...very useful. I sent an email to George Clarkson of Only Vintage Watches, who did several YouTube videos on refurbishing these movements and he opined that the coils "should be" interchangeable. Seeing the resistance readings on the 7T32 v. the 7T62, they are identical, so I'm satisfied they are interchangeable. I'm moving ahead with substituting a coil from the 32 to the 62 and I'll let you know what happens.

They’re the same.

Short coil for 7T32A 7T32B 7T62A
PN 4002711

Long coil for 7T32A 7T32B 7T62A
PN 4002700

Same in a few other movements too.
