... the 40th Anniversary appealed to me more on the pictures, but I was a bit disappointed when I checked it on my wrist. The finish of the dial and hands had a few flaws, the movement finish was - typically for Zenith - a bit technical, but flawless; except one plate of the automatic winding mechanism, that had lots of particles on it. I'd rather go vintage.
However, the Striking Tenth is a different league, and has the bonus of a very unique movement.
