"An automatic dive GMT with 300m of water resistance — a second time zone that's just as at home in a pool as it is on a red-eye flight."

Author POV

The GMT complication is what separates this reference from the rest of the HydroConquest range I've catalogued so far, and it's a meaningful upgrade — a second time zone genuinely earns its keep on a travel watch in a way a date window never does. At 41mm the case stays wearable, green dial and matching steel bracelet keep the styling consistent with the standard three-hand versions, and the 300m rating carries over unchanged. This is the HydroConquest reference I'd actually recommend for someone who travels regularly rather than someone who just likes the dive-watch look.
