Let's be clear. The products are great. I purchased the COSC C60 Trident Day Date. The watch is a thing of beauty and feels great on the wrist. However - despite fully winding the watch twice in the first month I noticed it was losing more time than I expected. Having worn the watch every day I wasn't happy with the amount of time it seemed to be losing. Some days it was as much as 7 seconds - way outside what I expected. I contacted Christopher Ward and after several email exchanges I was sent a 'prepaid' returns envelope. Trouble is this wasn't prepaid. £12 later I had sent the watch back. I got no email from Customer Services telling me the watch had arrived until I chased them. Then they informed me that according to their tests the watch was fine and they suggested it had not been fully wound - that is nonsense. There test showed the watch was losing only 1 second. They advised they might be able to make some improvements for £30. Now if it was only losing a second I would be very happy and I don't see how they would be able to much improve on that !. I told them to send the watch back as they said I could not return it as it was not 'pristine'. I've had the watch back 10 or so days. I set the watch on Monday 7th August at 14:00 now 76 hours later the watch has lost 14 seconds. OK that may just be on or over the 4 seconds they can claim for this COSC certified watch but it is nowhere near the -1 second a day they tested at. Really unhappy about the level of customer service as this was the reason I went for this watch over other brands. I was tempted to go for the Tudor Black Bay but thought I would given CW a go. Lesson Learned. Watch is great looking - but time keeping not within my expectations. Customer Service is shocking. Paul
