Military Pulsar battery change...

Look like its time again for battery change. This time its the Pulsars that require battery change. The good thing or bad... is all the three require their battery changed at the same time. 

Please note this is not a step by step instruction on how to change the battery. I would suggest you send your watches to a proper service center if you want to change the battery.

The new batteries. These are from Seiko. I don't mind using these as replacement for the Renata batteries. 

The old Renata battery and the new one.

The back of the watches. One of the watches have had its military markings removed to civilianize the watch. Please note that the serial numbers have been photoshopped out. 

The old batteries have been removed. Please be careful with the Teflon or plastic gaskets. Also do not use metal tweezers to remove the batteries.

The inside of the case back is marked S. Epson Hong Kong. :) Note that not all the watches have this marked on the inside of the case back. 

 

The movement is also from S. Epson.

Batteries installed. Check the watch is working before installing the case back. The car back is the snap back type. 

All done. 

What I do late at night.....

It was late at night and I could not sleep. So what did I do? 

This....

Yeah another battery change...

Getting batteries late a night was not a problem as there is a 7-11 just around the corner from where I stay. And the best part about Casio G-Shock is that they tend to use batteries that are pretty common and easily available.

Remove the end pieces... I remember my last battery change. :)

The 4 screws to be removed.

Screws removed.

The movement exposed. Note the gasket and rubber spacer on the case back. 

Unlatch the locking retainer. 

New battery in. 

Transfer the gasket and rubber spacer from the case back to the movement side. This is ensure the gasket and spacer sits in the right place. And don't forget to lubricate the gasket.

And don't forget to reset the module before closing up the case back.

All done.

I don't have the original blue strap for the watch and it is currently mounted on a blue/ gray NATO strap. I will need to check with my local Casio Service Center if they have the original straps.

Battery change season begins...

Yeah its battery change season again... and this is the first batch.

We have three watches and the watches are...

DW-5600B-1AVER

DW-8600ZJ-1T Fisherman

DW-5600CL-1DR

Please note this is not a step by step instruction on how to change batteries in Casio G-Shock. Note this post is photograph heavy.

First up is the Fisherman..

Case back screws...

The case back is made of Titanium and is held by the 4 screws shown above. 

Case back removed. Note the rubber spacer/ protector.

The rubber piece removed. We now have access to the battery. 

The battery is held in place by the clip. You need to pry open the clip by pushing on the tab.

Closer view of the tab.

Tab open, battery ready to be removed. 

Battery removed. 

Replacement batteries from your neighborhood 7-11. Cheaper then getting at my friendly neighborhood watch guy, sadly. 

New battery in. 

The locking clip.

Case back on. Don't forget to lubricate the gasket before closing. 

Why I love this Fisherman model...

Next its the turn of the DW-5600CL.

I thought I could get to the screws and do the change without removing the strap. Mistake no. 1....

The screws removed. Mistake no. 2, yes I have to remove the end pieces to remove the case back. 

The end pieces removed. 

Closer view of the end pieces. 

Now we are ready for the battery change. 

Case back removed. We see the rubber spacer/ protector. Oh what is that on the inside of the case back?

Warning.. don't forget to reset the watch after battery change. 

We see the same setup at the watch earlier. The battery is held by the clip. 

Clip unlocked and battery removed. 

New battery in and the reverse process to close up can begin.

All done. Note the reverse red display. I like...

Now its the DW-5600B. This one is unique due to the strap used on the watch. It reminds me of the flight jackets used by military pilots. 

The holes are access points for you to gain access to the spring bars. I found that it easier not to use them as it is very small. 

The mounting points of the strap. 

The DW-5600B. Another watch with reverse display.

The case back. And the same process as the watches above. Nothing much to explain... :)

Closer view of the locking clip.

Old battery.

New battery.

All done. Batch 1 completed. :)
