Design: IWC Portofino vs. the Portugieser Chronograph

The design of both these watches from the IWC collection, the Portofino and the Portugieser Chronograph, are inspired by pocket watches. In fact, the very first time-only Portugieser (formerly known as the Portuguese) from 1939 was a hunter-style wristwatch powered by a pocket watch movement. While the Portugieser Chronograph version only the joined the lineup in 1998, it kept most of the signature design details of the inaugural model from 1939. The Portofino, on the other hand, made its debut in 1984, drawing inspiration from Lépine pocket watches.

This IWC Portofino has a few special components about it.

In terms of sizing, the case of the Portofino Hand-Wound Eight Days ref. IW510103 measures a generous 45mm while the Portugieser Chronograph ref. IWC371482 is smaller at 40.9mm. Yet, due to their movements, the 11.7mm thick Portofino is slighter slimmer than the 12.6mm thick Portugieser Chronograph. In our specific examples, the Portofino is crafted in stainless steel while the Portugieser Chronograph is in 18k rose gold. However, both collections offer models in steel and gold.

The Portugieser Chronograph has two subdials that help the user measure time.

When looking at the face of the watches, you’ll notice that they’re both expansive thanks in part to slim bezels. The Portugieser Chronograph ref. IWC371482 has its characteristic duo of registers at the top and bottom of the dials—the minute counter followed by the running seconds, respectively. Furthermore, the slate dial houses Arabic numerals all around in addition to the tachymeter scale on the periphery.

Conversely, the Portofino Hand-Wound Eight Days ref. IW510103 has its characteristic stick indexes encircling its silver dial joined by a sole Roman numeral at 12 o’clock. There’s also a subtle outer minute track. The well-balanced dial includes a date window at 3 o’clock, a running seconds subdial at 6 o’clock and a power reserve indicator at 9 o’clock.

Movements: IWC Portofino vs. the Portugieser Chronograph

Beneath the cases of the IWC Portofino and the Portugieser Chronograph are two very different watch movements.

As its name suggests, it offers the wearer an amazing eight days (192 hours) of power reserve, which is indicated on the dial.

IWC Portofino or the Portugieser Chronograph?

Both the Portofino and the Portugieser Chronograph are incredibly popular models within the IWC catalog. And given their beautiful designs, that isn’t a surprise at all. The Portofino is larger but slimmer while the Portugieser Chronograph is thicker and includes the duo of pushers for more heft. One is manual while the other is automatic. In our examples, one sports a steel case with a light dial while the other has a rose gold case with a dark dial.

As with any other luxury watch, it really comes down to personal preference since either the IWC Portugieser Chronograph or IWC Portofino would be a fantastic addition to any watch collection.
