V72 Copy in Venus/Lemania case?

[archibald]

Sorry about my lack of research (I'm sure there are 167 threads on this on the old site) but I just received an offer for a v72 copy movement so cheap that I think is going to go almost immediately.

Will the V72 copy fit in a case built for the "venus" copy? I don't really care about the hands/subdial spacing, etc since the hands and dial will be swapped out--I'm just worrying if the depth and diameter of my venus case will be sufficient or too-sufficient.

Also, I just bought a dial to fit the Lemania 1870 movement. Anyone know I can use it w/ the either venus copy or my soon-to-be v72 copy, or if I'll be screwed by the spacing?

Thanks in advance!

I think you'll be screwed with the pusher placement. The V72 has different asymetrical spacing.

The measurements for the Venus Seagull T19 movt are:

Sub dial spacing - 15.50mm

Hand fitments are :

Subdials - .26

Centre seconds - .26

Cannon pinion - .94

Hour wheel - 1.40

What are you trying to retrofit the movement in? Vintage Daytona case? or some other sort of chronograph watch?

A couple of items to note-

-Pusher spacing as Euno mentioned. The V72/V23's reset pusher is much more offset than the start/stop. You can probably fabricate something to work, but it's something to consider.

-Subdial spacing. The subdials may be slightly different.

-Hands for the 'copy' V72/V23 may be a difficult thing to source. Hands for an actual V72, I believe, are not a direct fit on the copy.

-Actual fitting of the movement- The stem hole may not line up correctly in the case the venus was in. It might require a spacer, or modification of the case to get alignment correct.

-Reliability- The Copy V72/V23 is sometimes a crap shoot. Just never know how good/bad it might be.

Of course, if the price is sub $50, it would be worth getting. Any more than that, and it might not be cost effective.

Just my $0.02...

Best,

Randy

Thanks for the very useful infor Finepics and ubiquitous.

Because I am a dope, this is for yet another muller franken--even though I haven't finished one yet because the hands do not exist on planet earth--I just bought an OEM ronde chronograph dial from the early 90's--muller made some powered by heavily decorated NOS V72's and some by the lemania 1870--I won't know which till I get it.

Looks like I'm screwed either way--the subdial sapcing on the 1870 is different than the venus and 1870's are nearly impossible to find (and afford)--and if the dial is for the v72 version, I'll have to worry about the pushers or have a new case milled, keeping the bezel and back the same, which sounds really expensive.

And then of course there is the same old problem----hands hands hands. Someday, though, I'll find a cheap source for custom hands.

Anyway, thanks again guys.

Not sure if it's any use but I have a Poljot 3133 for sale (VJ 34). The measurements for it are:

Sub dial spacing - 15.90

Sub seconds (left hand sub dial) - .18

Sub minutes (right hand subdial) - .20

Centre seconds - .26

Cannon Pinion - .90

Hour wheel - 1.40

the venus movement is 14" when the valjoux is 13" so the VJ should fit the venus case, I don't think asymetrical pushers would be problematic, I've seen lemania fitted on DW cases with asymetric pushers...so maybe you could do the inverse swap?

I'd be more concerned about the tickness o both that could make it impossible to fit on the FM case.

The thickness of the Poljot is 7.34. The pushers are 13.75 apart.
