OP I Movement

Ignore what I wrote earlier

Think DuDro has it nailed - the difference between OPI and OPII is that OPII has a second hand wheel and COSC certification.

Still think they are both 21.6KBPH - be that beefed up 6497-1 or 6497-2 ....this artical sheds some light on early movements used ...

Both OPI and OPII have second "wheel" or gear, it's just that on OPI the second hand pin is shortened or clipped, but still left long enought to sit properly inside the jewel on the base plate (dial side).

If you remove the sec hand gear the watch wouldn't work :)

You're correct, they're both 21.6kbph, ETA/Soprod 6497-2 mov'ts.

cheers,

The preV (pre Vendome) watches which include the 5218/201A logo, 202A etc used the original slow-beat 6497 as the base movement, but the first of the Swiss (Vendome), preA watches used the 6497-2 higher-beat movements. However the preA movements were decorated in a style very similar to the cdg decorated 6497-1 which is currently available.

Still a point of contention amongst gen pre-V owners, many believe pre-V's came as 6497-2 in 21.6kbph flavor, but there's a good deal of those that believe it's a slower 18kbph...hard to say really unless you open one and check the number stamp.

cheers mate,
