Ocean7 just released a solid ceramic dive watch the CP-1. I of course ordered one for several reasons: I dont have a ceramic dive watch in my collection, are there others?, and I love to support a local business, Ocean7 is located not too far away from me . Watch is powered by an ETA 2824 is 49mm (not sure if that includes the crown) X 56mm lug to lug, so its a big boy and not for the 39mm is the perfect watch size crew . link to the watch is on their facebook page. I am not affiliated in any way with the brand just passing on info in case anyone here is interested. watch is a limited edition of 100 and price is really nice.
