I had MWO1 since 2014, when the book was published. I have plenty of notes, post-its and annotations inside now. It's been my workbook for three years now. Got myself MWO2 anyway, for all additional infos and watches that weren't in MWO1. It's definitely worth the price !
Will keep MWO1 as workbook and MWO2 as part of my Speedmaster-related stuff collection.
