Hi I have replaced a similar J-Springs battery but was baffled by the label on the inside of the watch back "after installing the battery, be sure to short + on battery with 'Area AC" - I do understand the principle but where, or what, is 'Area AC' please? Your advice would be appreciated.
Shortcut battery with AC contact. AC can be found on the sides of watch movement(very tiny). You have to use pointed tweezers: one end on battery+, another on AC contact for three secs.

Turn the watch sideways & look around the edges of the back of the watch. You may have to use a magnifier to do this. Look for an area that has a gap. Put the knife there & pry it open. Hope this helps.

I have a Timex Digital Heart Rate Monitor 585 (product code T5C351F5)m, which has the same Short AC Pad and battery +ve message. There is an arrowhead pointing to the pad. It's a raised metal platform - a bit different to some of the Ironman's mentioned above. Here is a pic...
SOURCE: I am trying to change
I have a similar model. The electronics sometimes needs to be reset after the battery is changes. Get a magnifying glass and look closely at the stainless frame around the battery. There is a small AC mark and a triangle which points toward a small gold contact down in an adjacent hole. This contact must be shorted momentarily to the + side of the battery to reset the display. You can bend a metal paper clip to make the connection. You may have to try several times before it resets. It should reset to 12:00 and start running.

This is a little tricky, I think this has a screw on back. It takes a two or better a three prong tool to remove back. A new seal shoud be on hand to replace this. Watch should have a consumption test and a min run voltage test, if either of these fail a new circuit board or movement should be installed. Take it to a good watchmaker and they will clean the outside before opening and do a water resistance test after assembly.
