The watch is also lauded for its captivating blue-on-blue aesthetic, translucent wave dial, and the compelling story behind its construction from ocean-recovered plastic. Some owners question the ultimate purpose of the #tide's recycled material aspect, viewing it as potentially gimmicky, while others appreciate the conservation narrative and the bracelet's origin. The crown action is noted for its satisfying clicks. Overall, owners rate the Christopher Ward C60 #tide highly for its outstanding value and unique eco-conscious story.
