Hi,
to expand on Roni's post, both the 565 and 2508 are screwback and thus water resistant.
There was the 12-120SC movement used in the 30's and 40's that was also center sweep second.
The 27SC being the most popular, it also had the double geneva seal signifying a chronometer rating... my all time favorite movement

Thank you very much for this.
Btw, since our dearest moderator did not allow the links to be posted, i missed it.
Would you mind PM me the link of the website instead? I'd like to read more!
Don't forget to put spaces between the address as the PM system does not allow webpages and emails to be posted directly.
Looking forward to it!

Cal. 12 SC was equipped with a special device provided from Piguet which modified Cal. 12-120 to a center second movement.
This caliber was widely spread over many different references and I recall several Calatravas Ref 96 and Ref 1491 with this movement.

Erich
Thank you Erich!
Much appreciated

The 3483 is also a screw back.
I dont have any movement I favour more than another. Why do you favour the 27SC John??
2 reasons. I really like sweep seconds vs sub second and it has a chronometer rating which in my book puts it on the top. Very accurate and robust movement.

Sweep seconds are very very beautiful IMHO and the word "Chronometer" just gets me going!
And not to mention "Very accurate"!
Wowsa!
