I'm a huge watch freak and because of such, have always worn automatics. but in the world of dive watches, i find i know nothing. haha. i've been trying to research dive watches for my boyfriend for christmas and am torn between quartz and automatic/self winding. does a quartz movement fair better for diving? i've read that a lot of the automatic movement watches lose time by seconds when used for diving repeatedly. initially, i was drawn to the St. Moritz Shadow II Chrono for its aesthetics but have recently been leaning towards the Citizen Cyber Aqualand NX. can anyone shed some light on this for me? THANK YOUUUU!
