The Carrera Seafarer arrived at LVMH Watch Week 2026 carrying one of watchmaking’s more useful complications: a tide indicator calibrated to the 29.53-day lunar cycle. It reads high and low water directly from the dial, with teal and yellow quadrants mapping the tidal rhythm across the face. The complication traces back to a 1949 Heuer patent, dormant for decades, and is now running inside the new in-house Calibre TH20-04.
The movement is an automatic with column wheel and vertical clutch, running at 28,800 vph with an 80-hour power reserve. The 42mm case measures 14.4mm thick, is rated to 100m, and is finished with a domed Glassbox sapphire crystal that gives the dial a pleasing vintage curvature. The beads-of-rice bracelet references original 1960s Carrera pieces directly. This is not a moonphase dressed up as something purposeful. It is a tide complication, which is a different thing entirely, and the distinction matters if you spend time near water.
At $8,800 it sits at the top of the Carrera range but well below the halo territory. For a watch with a genuine in-house complication this specific to its intended use, that positioning is hard to argue with.
