The world of dive watches is vast with the likes of Rolex Submariner, Omega Seamaster 300M, Tudor Black Bay line, and the Pelagos line. Of course, we also have the likes of Seiko and Citizen. Longines has had the Hydroconquest, a solid diver dive watch, in their line up but it was in need of an update. Longines finally gave the line a huge update in 2023 by offering the extremely popular Hydroconquest GMT. However, while 41mm is a great size, the watch community has been asking for a smaller and thinner version of the Hydroconquest.
