I really don't mean to beat a dead horse here, but considering the expertise present here I'd like to once and for all understand whether it's good, bad, or neutral to run a chronograph continuously. So far I've heard: For laterally coupled (column wheel ... 

I would also be interested in reading the experts opinion, on that. Good idea, Ed. Nicolas

I was curious about this question and I did some research on the past. I also did some live tests using a time machine. Here is what I learned: 1) If the movement is laterally / horizontal coupled (Omega 321/861/1861, Zenith El Primero etc.) there are con... 

... is not subject to wear when it is not running. No system engaged will become better when it is running, but the wear will be more or less serious depending on the construction. Sounds banal, but I think is the quintessence of the issue. Marcus

for ANY mechanism that causes movement of any part in contact with another part- there WILL be wear if it is running. Even if lubricated, there will be wear eventually. Especially with setting mechanism parts. With that in mind, all mechanical chronograph... 

...apart from the fact you might like to watch the chrono second hand. And as a disadvantage, for a watch which is running dry there is a possibility that significant wear might take place over a long period and the timekeeping might be affected. However,... 

Hello All, I've written about this extensively in the past as have others more knowledgeable than myself, but perhaps it's not so easy to find the posts and/or it's just an interesting topic to chat about from time to time. Traditional, lateral clutch chr... 

That was definitely the response I was looking for. I was waiting for you to chime in on this.

explicitly warns about letting the chrono functions run all the time, because of unnecessary wear on the triangular or pointy teeth. Thanks to all for a most instructive thread and your own contribution - which helped to clear up a few vital "points" : -)...
