13ZN Chronographs Inquiries and Information.

Any thoughts on these coarse, machining marks? I do not recall encountering them before.

minutenrohr · Feb 28, 2017

Me as well. Never saw it on Longines cases. Russian machine tools from the first world war? for guns or tank tracks?

Be careful out there...

Is it an early Longines service-dial? Looks near (but only near - f.i. the "5"s of the minute track) to original...

@minutenrohr Thank you for providing this information and your thoughts.

As for the dial, I do not know if it could be a service replacement. But I am confident that it is not original. As you have stated, the minute track has problems. The signature looks imprecise to me, as well.

Concerning the 13ZN black-dialed fake: Seller did not answer but a 10000-bid was cancelled:

The black dialled fake 13ZN sold for 15.000 € 😲

It was below 3000€ 20 minutes before the end of the auction. I presumed the bidders knew/ read this thread/ found out it was a fake.

I wish the winning bidder would read this as well and cancel the deal.
Sad thing, looks like the watch was only made to deceive and it worked quite well.

13ZN-12 is on eBay now. I love how the seller fudges the case and dial issues. He could easily get the information for free from Longines that will settle once and for all the movement/case issue. I also love the "$60k if the dial was 100% but I'm asking $14.5k" so I guess he's 25% sure the dial is legit?

Another badly redone dial, declared as "original"...

Furthermore, judging by the absence of shock-protection, I doubt that the movement began life in that case.

minutenrohr · Mar 12, 2017

...good point. In this case type should work a 6,9-7,3 Mio. movement number. But the seller has blurred it to prevent fakes and fraudulent abuse.
And there is no locking bolt beside the balance - typical for handycrafts.

It seems like Meertz frequently has suspect watches....

What are your thoughts on this one? The telemetre scale looks strange and in the second picture it looks like white-out was applied to it 👎

minutenrohr · Mar 15, 2017

...I cannot find issues on the dial. But, to be sure, one should have a look inside. I think it´s a relatively late dial version (?).
Nevertheless we have a small gold case with polished lugs and 12,500 euros are not a bargain. Otherwise Mr. Meertz would have sold this one a long time ago...

DirtyDozen12 · Apr 6, 2017

Thoughts on this one. The counter hands have been incorrectly switched, which is odd. More odd though is that the chronograph seconds hand appears quite oxidized, the case looks polished, and the dial is essentially spotless. A service replacement dial or...
