One thing is certain amongst watch collectors: if not all, at least most of us like a good dive watch. Sturdy, cool, purpose-built and suitable in most environments. So, what if you could combine a pretty good dive watch with helping a good cause, of course linked to the aquatic world. This is exactly what the new Carl F. Bucherer Patravi ScubaTec Manta Trust is, as this limited edition will help protection of manta rays.
