While I am not fan of annual calendars, as I find it in between the complete calendar and the perpetual calendar, I would gladly make an exception, here, because of the equation of time, which is- I don't know why- a complication which speaks very loud to me.
And as always, the case is superb, but the movement is too small.
But, overall, what a watch!
