The watch below is currently for sale and described by the seller as having a "prototype dial". I suspect that the dial was transplanted from another Longines (seen further below).

 

I have seen many tre-tacche with destroyed dials for sale over the last year or so. I am sure they will slowly resurface on different sites/ auction with some kinda "work" done and sells for many times they are worth.

 

"prototype"

From the archives (and translated from the original French):

"Hey – I have an idea! How about employing a center-second dial with a sub-second hand!"

 

Wow... it would have made more sense to just skip the whole second hand

 

Give Longines a break... This was probably one of the first sub-seconds watches, after the reign of the center seconds. They used what they could at the time for a prototype.

 

Okey, dokey. Break given...

 

Thank you for all of your responses.

Another rare Longines to add to the list.

 

Hi everyone.
The watch in question is mine.
Now it's no longer for sale because I want to examine it for good.
I mistakenly used the word "prototype", it was my mistake.
Your doubts are right but I want to understand.
I will introduce your to the results.
It was also a mistake to sell the watch without being safe.
The watch has also been optioned by a Longines collector, but I prefer to resolve the doubts first.
Thank you all and congratulations for your passion.
David.

 

Looking at your instagram page you look like a well established collector/dealer. Do you think there is a chance that the Longines watch mentioned above is legit?

Best regards, T

 

Thank you.
I think there are few possibilities but vintage always surprises us.
I've been collecting and selling Longines for 20 years, I'm not surprised at anything.
But I believe your doubts are founded.
David
