Please post a pic of Cal3135 movement with its engraved serial number

[RolexDivers]

Hi folks,
I have heard that each Rolex movement of each watch has the watch's serial# engraved on the movement.

Can someone please post a pic of the 3135 movement showing the serial# and its location?

Please hide the serial# ---- I just want to know where it starts from, its location on the movement and how much of the serial # is visible and how easy is it to view.

If you do not have the Cal3135, then any other ROLEX movement will do... I'm sure the location is generally the same.

Thank you.

oops .. sorry about starting this thread... I did some digging and found this:

Looks like the serial# is visible at the 6'o clock position in the image above.

The movement serial is not the same as the case serial though, and most all movements made today will have some sort of serial or year of production mark that's known only to the manufacturer..

You are right on Padi ...but there is still hope. I can look at the quality of the engraving of that serial number and make another judgement on the authenticity of the movement...Any idea on the format of the movement numbers??? I mean do they start with a letter or letters follwed by numbers?

thank you

Just numbers as far as I know,and not really interested in the movement serials as there is enough fixation with case serials to last me 3 life times now. And even if there was no movement serial there is no mistaking a genuine Rolex movement .

there are some looky likey movements out there , but all they have done is try to get the rough color right ,,, theres no mistaking a genuine movement , if you have something to compare it too at first , a good picture would do , and some light and some time too.

Very true...I have a 16610 and 16613, same movement ... so as the ultimate test in verifying authenticity of a sub I am interested in buying, I can open the case back of my 16610 and compare... the results should be very obvious when observed carefully.

The problem is that I have not opened the case of any of my rolexes and never seen a real rolex movement. So my experience there severely lacks. When you say there is no mistaking a genuine rolex from a fake, you have to know what a real rolex movement looks like and that learning experience can only come from looking at a real rolex movement...

May be I should open the case of my 16610 and take some detailed pics...

Here's the 3135 in my 16600 SD (1990 - 'E') Movement serial no. is by the HEV/9 o'clock

thanks,,

You're welcome - it's visible in all 3 pics, but I obscured some of digits in all images.

Yes indeed you hid it so well that I though the start of the serial number was hidden behind the screw at the 3'o clock position in your 2nd pics from the top.. then I looked carefully and noticed the hazing on the photo...

So it looks like that the serial # of the movement is cleary visible in a movement without the need to take anything apart.

Great pics!

Well, since you're buying a watch with the same movement as a watch you already have, you could just bring your 16610 and put them both up to your ears.

I recently bought a 1970's OP Date, and I brought along my 1970's Root Beer. I held both up to my ear and they sounded EXACTLY the same. Not super scientific, but certainly easier than opening up two casebacks.

Any movement with a 28k beat may sound the same.
For instance my Rolex & PP Aquanaut sound very similar.

Fair point. My Sub has a noticeably more high-pitched/metallic sound than my ETA's, but it's certainly not an ironclad technique.

Amen!

I'm not exactly sure why I found this thread enjoyable to post in, but I did! I've never really listened to my 16610 before, I'm not sure why but it sounds pretty cool. I've been reading a lot lately about the 3135 movement and its amazing to me how it performs day after day hour after hour for many a year. Its nothing short of a powerhouse!

Well most all movements that beat at 28800BPH would sound very similar case size would make a slight resonant sound difference.But most all movements today when correctly serviced will run for decades.

Thanks for taking notice of my post padi56, I find your knowledge base very helpful and enjoy it when you chime in on topics, especially in the technical aspect of the watch in general. I like things that are made well and while I've owned my 16610 for a longtime now its just been in the last few years have I cared to learn anything about it. Its my main reason for being a part of the forum. Crazy how I have never thought to mute the tv and listen to it before tonight. Its just kicking ass inside the case. I read a thread once where you had said what the amount of beats per hour and minute and all that was and it just fascinated me to no end. I had just never even thought to give it a second thought , after I read it I ran into tell my wife about what my watch can do and she just looked at me like, well that's nice honey.😀

Wow i've never noticed that right there that does give a better way of authenticating a piece. Feel like opening mine just to see that.

Can't date the movement Serials - they're random
