...contact "Reset(AC)" point quickly

[your_man_in_Hamburg]

Today I opened my Nixon Heat for the first time. There, on the back of the battery clip, was a sticker saying

1. Replace a new battery
2. Use metal tweezers to contact "Reset(AC)" point quickly
3. If it doesn't work repeat step 1 & 2 again

I will not digress and tell you all the things I find amusing or disturbing with this message, but cut directly to my question:

Should the reset point be connected to + or -?

Extra credit:

Why is step 2 necessary? Every other battery powered watch or clock I have experienced up to this point, have started as soon as you put in a new battery.

I would say connect AC point to the case...presuming it's connected to one side of battery.
When u change a battery, voltage fluctuations/spikes as you put it in and clamp it down can set registers with strange values. I've seen quit a a lot like this...Seikos etc from memory.
