I do love this watch (I'm generally as GO fan). And I figure one would invent a way to rather immediately know the month—this one's easy, as it's the tenth month. But 52/4=13, and, there being only 12 months in our calendar year… Take January (my month) of this year—if the watch registered wk. 5 we might still be in the 1st month, and the date would make it obvious that wk. 5 would begin in January, but fall predominantly in February. I'm sure theres a way to get tangled up by the time one gets to April or May. But maybe not! I'm certain one of our savvy business-minded members could show us just how easy this turns out to be. Big congrats massi, and I agree, great photo! FH
