I have bought C60 Trident Pro 600. Firstly, I was satisfied the process of delivery. It is believed that everyone wants to receive the watch as soon as possible after making order from the website. Christopher ward has made the delivery smooth. So the watch can reach to me on the reasonable time. Also, the quality of the watch is awesome. The design is stylish and unique. The ZrO2 ceramic bezel and steel are charming and eye-catching. The Sw200-1 movement is reliable and accurate. After 12 hours, it only get +1 sec. Although short-time test is not convincing, it has really surprised me. I will keep looking on that. And the box, owner's handbook and receipt are also in good quality. Last but not least, I would like to thank to the customer service of Chr. It always replies email fast. Concluding in one sentence, I don't want to take off the C60 from my wrist.
