I want to bay Master Grand Taille but I heard that it can have tolerance of +/- 10 sec a day. My present cheaper watch have only +2 sec a day. Does anybody ca confirm that?
I don't know where do you heard that but the calibre 889/2 is one of the finest on current watch market. I bought my JLC MGT two years ago and since there is running constantly +/- 1 sec per day
