Hi Guys,

I've been looking into getting a decent Seamaster for the girlfriend and am trying to decide between the 2583.80, the 2571.81 and the 2581.81.

Does anyone happen to know what the difference between the 2571.81 and the 2581.81 models was?
I know the 2581.81 was a Japan only release but haven't been able to find any information other than that.

I realise the colour is slightly different (with the latter possibly being darker) but I'm not sure if this is due to lighting issues.

Also, does anyone know if these are suitable for diving?

Any input would be appreciated.

Regards,
Min.
