Vecovo's record-setting mission comes as part of a larger project, dubbed "Five Deeps," which will see him reach the deepest points in each of the world's five oceans. To build a watch for an expedition like this is no easy task and while Omega used the Seamaster Planet Ocean as a jumping off point, it's safe to say that the Ultra Deep Professional isn't like any other Seamaster that's come before. First off, the case is made of titanium cut from the body of the Limiting Factor, tying it directly to the submersible itself. Additionally the way that the crystal is joined to the body of the watch is inspired by the way viewports are designed on submersibles to better distribute pressure – a patent is currently pending on this design too. The watch is certified to 15,000 meters, so Omega knew it would be well-equipped for its mission, and it comes in just under 28mm thick. While obviously chunky for daily wear, this actually isn't crazy when it comes to watches like this (of which there are obviously very few).
