My wife purchased the Trident C60 Day Date for my 50th. Arrived late and had additional delays. Lovely looking watch, well weighted and the day date complications are wonderful. However despite its COSC rating this watch loses over 4 seconds a day. When I returned it CW claimed it tested at only losing 1 second a day. Not sure how they tested this but it' not by wearing it that's for sure. For someone who is obsessive about time keeping and hates to be late for anything - having a watch that loses time is much harder to deal with than one that gains. CW wouldn't refund as they say it wasn't in original condition and by that they mean I' had the nerve to wear it. Save your money - look for a pre-owned prestige brand and give these pretenders a wide berth.
