Presently, there is a Longines 13ZN (ref. 5415) listed for sale on eBay. While the watch is advertised as a "Parts Watch", the dial is described as "original and has not been refinished". Unfortunately, the dial is not original and has been refinished. The font of the signature is an obvious giveaway, as are other details such as the sub-dial fonts. The silver dial foot, in conjunction with the typographical anomalies, acts as further evidence. Additionally, the pusher tubes look unusually clean, the crown is incorrect, and a number of the hands are incorrect.

It should be noted that the chronograph second hand on the Cars and Watches example is not typical for a ref. 5415 that was invoiced in 1946. The circular counterpoise is more typical of chronographs from the early 1940s and before. https://www.carsandwatches.com/watches/rare-longines-13zn-doppio-linguetta Below is a comparison with another example of a ref. 5415 with a different dial variant. This one is presently for sale on eBay. The example on the left has a typical chronograph second hand. https://www.ebay.com/itm/233931574857 Maybe @Radiumpassion can comment on the pushers?
Below is a comparison with another example of a ref. 5415 that Phillips withdrew from an auction in 2017. Notice similarities in the signatures and sub-dials. The Phillips example is also a redial. I posted about it back then: https://omegaforums.net/threads/another-longines-13zn-at-phillips.58495/
But... but... What about Ebay's authenticity guarantee! State of the art equipment! Inspection points!
Thank you for the heads up @DirtyDozen12 Agree on the pushers. They look too big and with no pitting on the crome that would be expected on a used watch. Regarding the chronograph second hand on the cars & watches one, I have seen this before on other 5415 including a scan from a period catalog.
Nice work, @DirtyDozen12 To possibly buttress what @Radiumpassion said about the second hand, here is a scan from a 1949 catalogue, though the watches depicted do feature stick hour and minute hands:
@Radiumpassion and @Tony C. Thank you for your responses, and for posting those catalog images. I am open to the idea that ref. 5415 originally came with both styles of chronograph second hands. It seems that Longines transitioned from the circular counterpoise to the pointed counterpoise in the mid-1940s. These earlier examples of the reference (< 7'000'000) are on the cusp. Here are two more examples from the same order from Sotheby's and Andrea Foffi. Serial number is 6'929'168, order number 23'020, case number 54 https://www.sothebys.com/en/buy/auc...ines-a-stainless-steel-chronograph-wristwatch Serial number is 6'929'170, order number 23'020, case number 56 https://www.vwcweb.com/EN/Scheda/133/longines/rare-1940s-ref-5415-chronograph-doppia-linguetta
It's anyway a 37.5mm stainless steel waterproof 13ZN chronograph. A nice dialed one is way more expensive. I mean, if a watch is redialed, this does not mean that is rubbish. (if the buyer will pay, of course)
