Seiko Kinetic Battery Replacement (5M42, 5M62)

My father had an old Seiko Kinetic sitting dead in his drawer.  It is a 5M42 which was an early generation model with a capacitor and a 14 day power reserve.  The current calibers of today (5M62 for example) have transitioned to rechargeable batteries with 6 months or greater power reserves.

I offered to try to fix it for him.  I typically don't do repair jobs for people as I break the watch more often than actually fixing it.  But since this one was sitting unused for at least 10 years and I have since replaced it with several other watches for my father, I thought there's be no harm in the potential failure of fixing this kinetic.  Since I could get the second hand moving with some shaking of the watch, I figured all it needed was a new power cell.
