    .

    If I'm reading your post right, the picture you attached isn't acutally of YOUR watch? If so, I'd recommend get a picture of the actual watch. Many watches look very similar, with the differences being subtle enough that you can miss them if you don't know what you're looking for.

    Beyond that, what exactly are you looking for? Just the caliber number?

    Thanks, but my caliber is exactly the same. Im looking for caliber number/name, catalog information and anything else.

    I know the year of manufacture approximately by the table.

    Is it exactly the same or is the bridge different?

    36.5-37mm would be a little bigger dial side due to a hidden lip and would be around 38mm, making it a 17''' movement. That movement you show, if 17''', would be a Cal. 17''' V.S.I, without the elaborate fine adjustment on the balance cock, it would be a Cal. 17''' E.P.V.S. Be careful - the exact sizes differ so you have to be sure of the exact movement! The 17''' V.S.I is 38.6mm and has a height of 4.25mm, the 17''' E.P.V.S. is only 38.1mm and 3.4mm high. The escapement wheel cock on the two also differs marginally in shape.
