Can anyone identify this 3135?!?

[Micha Nbg]

Hi all,

​​​​​​​I bought a BP 16600 some days ago and need help to clarify which movement is installed.

I appreciate your help!

Looks like a clone movement, but can't tell if its a VR or SH. Is the hairspring blue-ish?

Very difficult to take pictures, but I think it's bluish...

It's should be a VR3135 then!

 

[BensUhren]

It's a SH3135

 

[Kingsman]

It's a SH3135

Since when does the SH have a blue parachrom hairspring?

Looks like VR3135

Thanks for your support!

But I'm still unsure what movement it can be...

Any other thoughts?

Looks like a VR3135. Blue spring, reversing wheels are completely coated, ratchet wheel shows expected lustur and balance Jewel and clip looks correct. question is why did someone swap this movement in an SD? Is it a franken? Only reason I can think of as the dial feet would be cut, different hands needed and a correct date wheel is needed. It would be cheaper and easier to swap an ETA 2824/36 depending on the age and movement present vs this conversion if it's not a franken. The ETA swap would overall be more reliable in the long run.

Do this, when you turn the crown clockwise, which way do the hands move? Is the date change an instantaneous snap or a slow turn over a few minutes. This would help verify its a clone movement vs a standard A2824 or 2836. The pictures indicate a VR 3135 as said, so these tests are for you to confirm this physically vs visually. Is it a franken? The movement swap still has me confused on the why. How about a few pictures of the front?

Four distinct feature of vr3135 is the blue spring, guiding pins for the pallet fork, somewhat coated automatic gears and the stupid fixed balance wheel bridge nuts. You notice the nuts underneath the balance bridge will not move.

Hi, thanks for your help!

When I turn the crown clockwise the hands also goes clockwise. The date snaps immediately with no break.

Here's some pics from the front.

Thanks for your support.

Very good question mate!

I really don't know why the previous owner did this.!?!

Movement looks identical to my vr3135, why doesnt have the cyclops over the date?

Ok thanks!

The 16600 SD hasn't a cylop. ;-)

I can't come up with any logical reason why you would do that swap. The only reason would be if someone doesn't like the fact that ETA sets the hands in the opposite direction with the crown versus a Rolex 3135. As I said it would make more sense, and overall more cost effective, to have swapped in an ETA movement. Not always does logic enter into this hobby though.

I'll appreciate it, when you also give me a feedback.

Is it fine for a vr3135 movement?

What’s the different between two movements?

Another easy tell to identify a VR is the lack of "studs" near the screws on different bridges:

red is SH, Red is gen (but they are also present on SH), green is VR, and picture is from here: https://forum.replica-watch.info/for...n-gen-sa-sh-vr
