question about chronographs
I am a big fan of chronographs, I own a few, but one thing is uncertain to me: are there chrono movements that one can always keep in function without any harm and other where this is not advised?
I have read and heard all sort of opinions, enough to convince me start my chronos only occasionally.
Thanks,
R

That is a good question, which would deserve to be posted in the WatchTech Forum.
Only the watchmakers among us can provide you a serious and elaborated answer, I think. Best, and let's see what they say! Nicolas
I wanted to post it there
But I thought that not many among us are visiting WatchTech regularly. Besides, WatchTech is really "Tech" from what I've seen.
I will try to respond
If you use the chrono module a lot, you may need to raíse the frequency of maintanance and Also the mechanism may loose seconds which may be a good thing, depending on which position you put your watch at night
Answer.....Yes
There are chronographs where the chronograph can be constantly running and, as you may have guessed, there are those where you are advised against doing so. First those where you should not leave the chrono running. Basically any chronograph which uses a ...
I get it!
Thank you for the answer and for the examples. Not only that I get it, I "see" it now. When you meant Patek manual chronos, was the 5070 (or Nouvelle Lemania based watches) included in that category? Is the El Primero exposed if used continually? Many tha...
El Primero: yes
Despite its aura, the Primero is a very conservatively designed movement; originally, cost saving was one of its priorities, which can be seen when looking at the simply stamped "sherriff star", aka column wheel (without columns, though). The current mode...
Thank you, Jeff, excellent reply. radu, yes, the PP5070 and other Lemania based
chronos were traditional clutch designs and thus subject to the caveat about continuous running. The only PP models where this is not a concern are the ones based on the new in house chrono base, with the vertical clutch. Chopard's Chrono One based models...
Thank you, TM!
Now, I've got this issue cleared. I am happy i did not mistreated my 5070 and RD Hommage. Best, Radu
Thank you for this elaborated explanantion, Jeff !!!
I would like to add that the Seiko 6138 en 6139 chrono's (autowind) also use a vertical clutch and can be left running all the time.... Kind regards, Bart
Thank you for your fear explanation ...
And it push me to trade a watch to a Blancpain chronograph that I was "dating". I'm not a frequent user of the chronograph function but I like to know that I can. Cheers, Nilo
To add to the list of "safe" movements
We should not omit JLC cal. 751 family of movements: also vertical clutch (I read somewhere that its design is very close to that of Fr. Piguet/Blancpain), plus some more modern extras (freely sprung balance wheel, two main springs).
