I was just wondering what the overall opinion is about the lemnia 5100?

Hi Peter,

If you've linked around or done a Google search on the topic, you've probably run head on to my opinion on the movement. But I'm sure others will post their thoughts.

Is it generally considered the most durable chrono movement?

Oh, I don't know. I am not sure even I consider it the most durable chronograph movement. The Omega c.321 and c.861 (Lemania 2310 and 1873 respectfully) are pretty tough movements to beat. But the 5100 is probably the most durable and rugged automatic chronograph produced by anyone to date.

Is there any plastic used in its construction?

Yes, there are synthetic parts, Plastic is really a misnomer, Nylon or Delrin are more accurate ways to define the parts. Yes, Lemania used non-metalic parts in a number of places on the 5100 where they did as good or better of a job than a metal part would have done.

Any insight would be greatly appreciated. Thank you in advance!!!

Dennis and SJackal included a pair of the most useful links for your learning, those being Jean-Michael's Lemania5100.net and my hosting of Watch Legends: The Calibre Lemania 5100 "Not beautiful but Rare" which includes a portal to Sergio Lorenzon's WatchScape pictorals of the Lemania 5100 and Omega c.1045 (Omega's name ffor it's version of the Lemania 5100) teardowns.

Of course and as always, please feel free to post additional queries if you have them. If I can't answer them, I'll point Pascal Straatsma to this thead. Between the two of us, we should be able to assist...

Good Hunting!
