About This Watch

The IWC Portofino Chronograph IW391036 brings the sophistication of a dress chronograph to IWC's most elegant collection, now powered by the in-house caliber 69355. This represents a significant upgrade from the previous generation, which used an externally sourced base caliber, giving the Portofino Chronograph genuine manufacture credibility. The 42mm case is slightly larger than the time-only Portofino, but the polished finish and thin bezel maintain the collection's dressy character. The silver dial features two subdials in a vertical layout — running seconds at 6 and 30-minute counter at 12 — which mirrors the Portugieser Chronograph's arrangement, creating a visual link between IWC's two most refined collections. The column-wheel chronograph mechanism ensures crisp pusher feel, while the Pellaton winding system with ceramic components provides durability. The Portofino Chronograph occupies interesting territory: it offers essentially the same in-house chronograph technology as the more expensive Portugieser but in a simpler, more modern dress-watch package. For those who find the Portugieser's railroad chapter ring and Arabic numerals too ornate, the Portofino's clean baton indices offer a more contemporary alternative without sacrificing mechanical substance.

In-Depth Review

IWC's 2022 refresh of the Portofino collection demonstrates the watchmaker's disciplined approach to updating a classic sports-elegant design. The 42mm chronograph retains the collection's defining aesthetic—clean lines, a refined silver dial, and a fixed polished bezel—while housing the in-house caliber 69355, a workhorse movement delivering 46 hours of power reserve. At 14.1mm thick, the watch maintains surprising wearability despite its chronograph complications and small-seconds subdial. The sapphire crystal and 50-meter water resistance confirm this is a watch engineered for actual use rather than display-case contemplation. Paired with a black alligator leather strap, the IW391036 sits firmly in the dress-sports category: formal enough for business environments yet capable of handling daily wear.

The Portofino chronograph appeals to collectors seeking understated mechanical sophistication without ostentation. This is the watch for the executive who values Swiss manufacturing heritage, or the enthusiast seeking a chronograph that doesn't announce itself through racing indices or contrasting subdials. The 42mm case accommodates larger wrists comfortably, while the refined execution prevents it from feeling oversized on more modest frames.

In the current luxury chronograph market, the IW391036 competes directly with pieces like the Longines DolceVita Chronograph and TAG Heuer's Aquaracer Chronograph. Against these options, IWC's offering distinguishes itself through superior finishing and the prestige of an in-house movement, though the secondary market price of $5,800—roughly $1,800 below MSRP—suggests stronger availability and slower appreciation curves than some competitors.
