Current drain, indeed! Very clever! It can sense the hand step signal through that and then work out the timing and any error from there.

I did the "cut and try" approach on a Seiko A829 LCD quartz for a couple of weeks and got it pretty well dialed in, but I didn't want to repeat that task for a couple of others in the queue. I wound up using a hack that saved some time, but I expect that would be about ten second job on your newly revived box. Nothing like the right tool for the job!

I was puzzled by the lack of amplitude and beat measurements for balance wheel watches but I guess that it's because that mode it was designed mostly for servicing electric mechanicals like the Hamilton 500, rather than conventional escapement movements?

And it's got LED's!
