New to me 105.012-65. Need advice re: correct pushers

Hello all. Long time lurker, first time poster.

Had an opportunity to pick up this 105.012-65 recently - knowing that it has incorrect (tall button/thin neck) service pushers installed, but everything else looks correct. With some searching of this site I've found that the correct (short button/thin neck) service pushers would be either p/n: 086ST0007 (threaded) or 086ST0089 (push fit).

Can anyone clarify what pusher the -65 HF case used - threaded vs. push-fit? It seems that all the fat neck pushers that I've seen sold were all push-fit, so I'm hoping that will be the case for my watch as I'm ultimately hoping to source a pair of them to bring this watch back to original/correct condition.

Thanks in advance!

You will probably get some opinions here, and possibly some good ones. However, the safest thing would be to remove the current pushers so you can be absolutely sure. That's what I would do. You will need to remove them to install the replacements anyway, so why guess.

Are you sure that's a 105.012-65? With the far-spaced Ts and what appear to be threaded pushers, could this be a 145.012 with a swapped caseback?

I'm waiting on the Archive Extract, so I cannot confirm for sure that the movement went into a 105.012 - but its serial number is correct for a later 1965, as are the wide Ts on the dial (per my research).

But now you've got my attention, as I'd not considered the case back could be switched onto a 145.012. The archive extract is likely a few more weeks out & I do have time to return the watch if it were proven to be misrepresented. If you would be so kind, could you describe the differences in the pushers for the 105.012 vs 145.012? Do the service pushers it currently has with the taller 3.5mm button not fit a 105.012? Thank you in advance for your help!

Looks more like a 66 HF case, but could still be a 65. Have you checked the serial number for the year?

The 105.012-65 case should take push-fit pushers. It’s usually possibly to see if there are threads for the pushers from the inside of the case using a loupe. If in doubt remove them to be certain.

I took a look at the inside of the case through my slit lamp microscope this morning. The pic isn't great, but I can get a great high mag view of the cylinder in the case that the pusher fits into & there are no threads showing. How far into the case do the threads tend to run?

In my experience the threads run right through so can be seen from the inside, therefore it looks like your case is for the correct push fit. However I guess you can’t be 100% until you actually remove them.

IMHO the pusher are service pushers.
You would need pair "short&wide" vintage pushers like these:

The neck is wider and normally they are not serviceable.
Hard to find too...

Thanks for the feedback, everyone. Encouraged that this does indeed seem to be a correct late-65 105.012 -- extract will hopefully concur.

Now I just need to find a pair of fat neck pushers. Please let me know if you have one or two you're willing to sell!

Cheers

As said, difficult, but not impossible to find. Expensive though.
You should wait until you get the extract in order to be sure that you would need them.
They will only fit 105.012 from 63, 64, 65 and 66 in both versions HF and CB.
Note:
The Speedmaster case back from 63 to 65 have a bezeled case back.
The 1966 Speedmaster has the newer version without bezel.
Very easy to see.

Cheers

Yes, it has the correct -65 caseback - and as mentioned earlier, the 321 movement serial number matches the late -65 range. The speculation about it possibly being a 145.012 with -65 caseback seems to be reduced/removed by the presence of press-fit pushers (to my understanding the 145.012 was all threaded pushers - and perhaps some of the late -66 HF cases, as there was an overlap in production). But a fair point about the extraction -- it will be the ultimate determining factor of the validity of this being a true 105.012-65 (fingers crossed).

As far as I know the change from the ref. 105.012 to the 145.012 points to the fact that the pushers
were changed to the screwed in type instead of the press fit type
