Omega Geneve Dynamic - 565 or 1000 Cal. - Is there a tell?

[kaplan]

Hi everyone,

I bought this for $100 for spare parts, if it's not a 565 cal. I won't import it, with these Geneve Dynamic models I find it hard to tell since there are so many models

Is there a tell, to determine whether it's a 565 cal.?

That doesn't look like the older case, so my guess would be a 1000 series.

As above. The tell is the case, the sharper edge first gen are the 565s, the soap bar look came in with the 4 digit el cheapo looking movements.
