This thread was prompted by a question from @Oku about the dial in Figure 4. My aim is not to depict every single variation of original and non-original 13.33Z dial. Rather, I hope that this thread serves as an introduction so that you can begin to train your eye. The dials depicted in Figures 1, 2, and 3 are all original, as far as I know. Admittedly, I prefer the style of the dials in Figures 1 and 2 over that of the dial in Figure 3, but I have come to accept it. The dials depicted in Figures 4 and 5 are not original, as far as I know. To me, this becomes most obvious when looking at the sub-dials. Finally, here is a potentially useful resource: http://watchexpertise.com/oldlonginespassion/Longines_Passion/quadranti_3.html Figure 1. https://onlineonly.christies.com/s/...ld-hinged-single-button-chronograph-122/34019 Figure 2. https://omegaforums.net/threads/my-13-33-arrived-advice-on-strap-style-needed.43187/ Figure 3. https://watchesbysjx.com/2020/09/longines-13-33z-first-flyback-chronograph.html Figure 4. https://omegaforums.net/threads/omega-33-3-dial-help.131025/#post-1777186 Figure 5. https://omegaforums.net/threads/longines-13zn-monopussante-enamel.44292/#post-523637
A good friend of mine told me to look for sharp edges around the hole for the sub-dials. Picture #4 doesn't even look like there's a hole for the subdials, just printed on the main part of the dial. Picture #5 the edges and the printing would bother me. Thank you for posting this and educating collectors what to look for. I have attached a couple of pictures of mine to illustrate the edges I spoke of.
Thanks for the photos. I agree that observing the edge-sharpness of sunken sub-dials can be useful when assessing originality. However, I have primarily applied this concept to non-enamel dials. As you noted, the dial in Figure 4 does not appear to have sunken sub-dials. This is highly atypical and one of a number of traits which suggest that the dial is not original.

Thanks Larry, i have read this article a couple of times but forgot about it (old age). This time I printed it out, now all I have to do i remember where I put it. Definitely a well researched and well written article, thanks for the reminder. Best John
I do not entirely understand your question. I do think that the dial depicted in Figure 3 is somewhat unusual and uncommon, though I would not necessarily call it rare.
Thank you ,Enamel dial is beautiful, coz I only saw this font in two pusher 13.33z. Is there any model with this dial but Monopusher?
I cannot recall seeing a monopusher (or non-flyback) example with the same dial or numerals, but I am not certain.
Yes, thank you for letting more longines collectors learn a lot and share your knowledage , so I think if there is a Monopusher with these slender font, I think is rare to see and collectible , Of coz, two pusher is already collectible
