Case O-Ring Cleaning and Battery Replacement


JJx

Recommended Posts

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?

Check out the Seiko service document.

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.

    • Never seen that but yes very practical Hector 
    • Welcome, Simeon! I'm into Soviet watches too (not the political system, and yes, I am able to make the distinction, unlike some). They offer amazing value for money. I like your "Big Zero" profile image. It's a true classic and I have one of those myself. I noticed that the hands aren't the original. Not that it matters a lot but here's an interesting article about the Big Zero if you haven't already seen it.
    • I was thinking will the gasket stretch at all to match the desired size.  Did i also deduce that the original gasket is thinner (0 .5mm ) than the cousins gasket ( 0.8mm )  could that just be an effect of you measuring the case for the gasket size  H  ?
    • if we look at and understand why steel becomes magnetised and unmagnetised then its possible to work out why some devices are better than others. Simpy it is a parallel alignment of atoms , electrons within a material caused by external magnetic fields. Different magnetic fields cause different alignments and non alignment of atoms. Fields by AC currents are changing atom direction approx 50 times per second ( 50hz ). As a material is drawn away from a demagging device the field is becoming progressively weaker while also changing the material's atom direction having the effect of returning their random directions ( demagnetising ) . To improve on this demagetising effect, try changing the material's orientation as it is drawn away.  Fields caused by DC currents have the most permanent magnetising effect as the currect is flowing one way only. A good demagger would produce random magnet fields and disorientation of the material's atoms.
