What to know

The Corcovado GMT gives the new Presage Cocktail Time GMT silhouette a more nocturnal identity. A deeply fluted blue sunburst dial meets rose-gold-tone indices, hands and casework; the contrasting brown leather strap makes it feel more like a traditional dress watch than a globe-trotting tool.

The 4R34 automatic provides a 24-hour GMT hand, date and about 41 hours of power. Its 40.5mm steel case measures 12.8mm thick and uses domed Hardlex rather than sapphire; water resistance is 5 bar. Released in October 2026 alongside the lighter Daiquiri model, this HCB005J1 is listed at €680 in Belgium.
