Vasco Grand Large Offshore puts a tide-gauge bezel on a 24-hour diver

Vasco's Grand Large Offshore looks familiar until the eye reaches its numbers. Instead of conventional twelve-hour time, the bright-white dial carries a full 24-hour scale. The surrounding rotating bezel is marked for high and low tide, using the naturally slow progress of the central hour hand to support a sailor's planning. It is a tool-watch idea that asks its wearer to think about an entire day at once.

The steel 39 mm case is equipped with domed sapphire, a 120-click unidirectional bezel, Swiss C3 luminous markers and a 200 m water-resistance rating. Vasco lists a TMI 4R34 automatic calibre, adjusted in its Bordeaux workshop, and quotes 41 hours of reserve. Assembly takes place in Bordeaux, France.

Vasco's original sales material lists the Grand Large Offshore in the 2025 pre-order collection. The white-dial model is now shown at €499 in several canvas and bracelet versions. It is existing collection coverage under New Releases, not a misleading October 2026 launch date.
