Why The Lemania 2310 Is The Greatest Chronograph Ever Made | Part I | Diving Deep

[@robynsjp]

Great vid. The 321 became and remains my grail. I was lucky to acquire and keep a 145.012-67 for 5 years now. I partly puchased it trading in 2 Tissot 6216 from 1939 and 1945, housing the CH 27.

Very nice!

Great content as always. Looking forward to part 2.🤔

[@amintaslneto]

Great educative video folks. Thanks for sharing!!

[@weezkidtube]

Seriously enjoyed this content. Wei Koh firing it up and the energy generated was great! Aiming to get hold of a 321 Seamaster to match my De Ville standard chrono.

Love the content and enthusiasm! I am a big Speedmaster fan. One thing that I think does not get enough attention when discussing the NASA certification is the robust construction of the case and its components. How the magnetic shield dust cover is held in place, and creates a shock absorber for the movement, and how the hands are riveted to their posts. Love my Speedies!

Thanks for the info fellas!

Wonderful video. A quick point… “in-house” movements. This is marketing that says in-house is something to rave about. Not true. The very fact that PP, VC and such used a lemania movement shows this. And I wan to further say that some folks think ETA movements are sub-par. This is just not true. They are robust and again to be respected for their design. Especially when reworked by the brand that uses them. ETA movements are not all the same. There are various standards for different movements from them. It seems as if some people think that ETA makes only one movement and they are all the same. So think again about “in-house” being that great. 🤝

Well said.

Great video...educational and well made.

The legends: Lemania, Minerva and Longines 13zn.

Minerva ❤

5970 and speedy using it is already enough to make it perfect for me

[@SteveJames-z1m]

Hi Thank you for a great video. May I ask did Lemania make a 5573 calibre? I was told that this movement was in my Chronograph Suisse Chronograph watch from the late 1940s to 1950s. However, I cannot find anything about this movement or a connection with Lemania, consequently, I am not convinced that this movement is in my watch. Thank you for your help in this matter.

[@RevolutionWatch]

I don't think I've heard about a Lemania calibre 5573, but maybe more in-depth research will help

[@sumitagg1]

How do you rate the Patek chronograph movement? Seems derived from lemania..

[@RevolutionWatch]

Part II will cover them throughly. Stay tuned.

Quick note. The 2310 is NOT easy to service. It is actually one of the most difficult movements to service. It is reliable, yes, but not easy. There are a lot of manual adjustments the watchmaker has to make. This is the whole reason Omega discontinued it in the 60s and switched to the 861. Because you need super skilled people even in production of 321. You don't need as many with the 861.

[@RevolutionWatch]

It's hard to produce yes, but for servicing might be subjective, based on the many watchmakers I know and work with.

Take a shot every time the guy on the left says "that's right". I dare you !!!

[@RevolutionWatch]

okay?

@@RevolutionWatch you'd be drunk after 2 minutes

[@petemorbius3936]

not 4130?

[@RevolutionWatch]

Without El primero, there is no 4130

Meg. Opinions are like ______

[@jamesblonde2271]

Venus 175 is still in production so beating Omega by quite a long chalk. You just say stuff don't you?

[@RevolutionWatch]

Read the title again. Or do you need us to read for you?

[@jamesblonde2271]

@@RevolutionWatch By which I mean its not the longest continuous production run, you're first "fact". Nice shade, Im illeterate? Bless your trans- oceanic socks....

[@Judah.Rosenthal]

Perhaps semantics but it appears that a) both were introduced in 1942 and b) Venus stopped production in 1960 and then resumed in China in 1963, meaning it hasn’t been the longest in production.

[@jamesblonde2271]

@@Judah.Rosenthal aaaah, bugger, at least you knew what I was on about, thanks for the info. Also Im pretty sure the 321 hasnt been produced every year has it, before the Ed White revival? All that PR stuff about how difficult it was to reproduce, aha! My riposte Sir.

[@Judah.Rosenthal]

@@jamesblonde2271 Yes. Breguet made it under a different name. I believe others did too, which frankly was why it’s confused me that Omega went on about their laser scanning before reintroducing like, “uh, guys.. just walk next door and pull one out of a tray…”

[@cal.3861]

It's too inaccurate timekeeping for me.
