Case O-Ring Cleaning and Battery Replacement

[JJx]

Hi there,

1st time replacing the battery on my oldest watch (Seiko World Timer Age of Discovery - 5T52). Here is a picture of one (not mine).

I'm seeking advice on a couple of things:

1. The case back o-ring/gasket is dirty, so I've removed it and cleaned the case back with a soft tooth-brush. How should I clean the o-ring?

2. On the inside of the case cover, there is a sticker which says "After Installing a new battery, short AC and + of the battery".  How do I do this?

Here is a picture of the sticker...

Any help is appreciated.

Thank you.

Wash gasket as well case and bracelets with soapy water.

Reset with tweezers tips touching the points indicated by the label.

Thanks jdm! So, once I install the battery, use my tweezer tips to touch the + (top) of the battery, but what is the AC and/or where is that located?

Generally you only need to short the two points for a second or so.

Also once you have cleaned the case and the 'o' ring, make sure they absolutely clean and are completely dry before re-assembling. You can apply a very small wipe of silicon grease to the 'o' ring to help it seal.
