Removing A Rolex Case-Back.....!!!

[Tools]

Some of you guys have inspired me....

So, let's open a case-back and look inside.....

First, we're gonna' need some tools:
A Bergeon 6111 to take off the bracelet and the right size socket for the case-back...and of course, my trusty EXP II.

And, we'll need a case wrench. I use the LG open-all.

Using the 6111, and the small forked end, we pull the bracelet.

Then we attach the proper size socket to the opener. In this case a 29.5mm Rolex socket. (There are 6 different Rolex sizes).

This is how the watch head fits into the LG opener:

Although the opener jaws are soft metal and not likely to do much damage to a SS Case, you can put a cloth in place as an extra precaution:
The socket is screwed down to engage the teeth in the caseback, then a short half turn and the case back is opened slightly.

I like to open the case back only partially and take a look. As you can see, there is some dirt and stuff on the "O" ring gasket.

A gentle brush with a soft brush and some dry air and the gasket is as clean as can be:

With the area clean so nothing will inadvertently find it's way into the movement, we can take the back completely off:

Now that we have the case back off our Rolex, we can see what is inside. In this case a beautiful cal 3185 resides with it's famous red gears and peacefully ticks away at it's 28,800 beats per hour rate:

A quick hi-speed flash of the hairspring stops it so we can get a better view:

And a bit closer in:

But, we can't leave it open forever.... Let's put the case back, back in place and snug it down: (45 inch lbs)

And, not a scratch to be seen anywhere.....At least, not from this operation.

Thanks for taking this little adventure with me...

That's a Bergeon 5090 Waterproof case holder. It will fit, just barely, but it sits way high and without a shim at the middle notch it doesn't hold it as secure as I would like..

Good stuff, Larry.

But how can you be 100% sure of the waterproofness of the watch just in case you've squeezed the gasket too much or mis-aligned it?

Just wondering!!

[DSJ]

Nice show-n-tell Larry!

[kcmo]

Cool! Thanks Larry!

[Irish Dan]

I keep telling myself,"It's not a 58 Chevy,
stay out of there".

x2 plus When the case back is removed at an RSC, it is done in a "Clean Air" environment to prevent micro dust particles enteing the movement. I would not think for one minute the average person would have this capability. However, thanks for an interesting post Larry

[Leighton]

Great post, Larry! Need to get me some tools!

[Roselló]

Cool. This is great. Thank you.

[frostie]

Great tutorial Tools

Thanks for posting it

[Letsgodiving]

Excellent post and very informative.

[Marrk]

Nice post, Larry. Very Jocke-ish!

[Z-Sub]

to watch the progression. Very good point about opening just a little bit and get the dust out first.
I probably will never open my rollies but opened my tags and others in the past and did the same to remove the dirt and probably soap scum build ups.

Thats is a very informative and extremely well illustrated article Larry
What about "snuging it down" do you have a torque wrench to do that precisely, how do you know the right amount of 'snugness'

You seem to have a pretty good workstation set up there.

Thanks for posting this!

Excellent stuff Larry.

To echo Steve's question.. how snug is snug?

[marshallr47]

Awesome stuff Larry. Very informative. This is the stuff I like to see. Thanks greatly.
