IWC

The first Portofino, 1984's Ref. 5251, used a classic hand-wound movement with small seconds at 9 o'clock and a moon phase indicator at 3 o'clock. In 1988, IWC introduced the Ref. 3730 and 3731 chronograph quartz. IWC released a classically styled dress watch in the Portofino line in 1993. This two-handed Ref. 2010 was just 1.85mm thick, with IWC's Cal. H/849. It lacked the rounded case and Roman numerals and used stick hands, unusual for the line, but lasted through 2005. Another departure from the traditional case style was the 1995 Ref. 3050 Romana Perpetual Calendar with its slab-sided case. Also produced through 2005, the Romana was one of the thinnest perpetual calendar watches at that time.

In 2003, IWC returned to the rounded case with the larger 38mm Ref. 3533. Once again, stick hands and plain markers were used, along with central seconds. The classic Portofino dial returned in 2008 with the "Vintage" model, which literally turned the original Portofino on its side, with small seconds at 6 o'clock and moon phase at 12 o'clock.
