Horological Meandering

Not really what I call a fine watch, but certainly a cool watch, with a big presence and a lot of character. This 30 CH is one of the last ( I think there was another one, after this Diving Chrono ) in house chronograph, before the Valjoux slippery slope,...  

Of the Longines chronograph movement. I know that everyone here loves the 13ZN but I prefer the 30CH because of a single "modernity" that is the shock protection. This one that you show here is a little funky (the red bezel) but it carries the symmetry an... 

And the breathtaking detail or information is the incredible variety of 13 ZNs and 30 CHs. I don't think it is possible to build a collection on this theme, which is way too wide. This one, the Diver, I mean, is breaking the code of classicism which is ex... 

Hello, Nilo, "... I know that everyone here loves the 13ZN but I prefer the 30CH because of a single "modernity" that is the shock protection..." Just in case I understood this quote correctly, I'd like to add a little bit of info - you can find the calib... 

Hi Suitbert, Many thanks for this precision. Does it look like something like this claw-like device? Credit P. Boutros for the second picture Do you know whether this form for primitive protection appeared on other models/ watch brands or was it proprieta...  

Hi, Yes, that's it. You'll find it implemented in many Longines calibers oft that period. As said, trademark is 'ShockResist', don't know which supplirr made it, but will check that. Btw, it's far from beeing primitive, :-) -it's just an early, I'd guess ... 

If you find more about the supplier or any other info, I'd love to read here. Best regards Z'

I never paid too much attention to this very important detail. Thank you very much, Nilo

those red bezels are so attractive, and also seen on the sister Wittnauers as well. Cheers, Tony C.

Even if it is not in the context of the Diver Chronograph that I prefer the 30CH. Fx

i wonder if they will ever recover the status they had in the 50's and 60's? will they ever make another in house calibre or will they stick with ETA, Valjoux and Valgrange? if Omega can do it and rise again from the doldrums of ETA to making excellent in... 

Group. There are other brands which reperesent the horological side of this Group. This is not fair, in my opinion, as Longines had such a prestigious past! Best, my FQ friend. Nicolas

To add a vintage diving chrono to the theme. For the miment, I only have the JLC Shark. How do we say? One stone, two birds? ;) Best, Juan. Nicolas.

Dear Nico, Many thanks for posting these very nice pictures. There is imho so much to like about this Longines ref. 7981-2: - a diver chronograph to start with. How many brands did have that? - the end of a long evolution / swan song of the 30ch line. I g... 

Eitan has a photo, if I remember well... Agreed on your points, my friend. Some bands released Diving Chronographs, in the same era. I immediately think about the JLC Shark, for example; But this Lo,gies is really something! Best, And Thank you! Nicolas

here is a Big Eye duo from this week's Paris GTG Matt ...  

Fab Matts! with reference to my previous message just above yours, this is yet another case of one picture saying it better than 1000 words. Many thanks for sharing this. Z'

You are generally faster than me. ;) Best, Nicolas
