IWC Portugieser Chronograph with Caliber 69355

At the start of 2019 IWC introduced a 150-year anniversary edition of their “Portugieser Chronograph” as a limited-edition. Now they’ve followed it up in 2020 with some extra dial options in a non-limited, current production series. There are other nuances we’ll extrapolate on below, but its core main novelty is a caliber swap: from the previous use of 89000 series to the now 69000 series of chronograph movements. If that hasn’t peeked your interest yet, these new editions will also sell at a lower price.

In terms of casing these models are available in stainless-steel or an18k 5N red gold with a diameter of 41mm. Unlike there previous solid case back releases, in 2020 they’ve been give a sapphire exhibition case back that allows to view the inner workings of the swapped caliber movements.

It comes equipped with two pump-style push-pieces to operate the chronograph functions, plus a setting-crown in between them. All topped by a sapphire convex crystal with an anti-reflective coating on both sides, which also assists with water-resistance on these watches reaching up to 30 meters (98 feet).

Time can be exhibited on either a blue (just like the previous limited edition anniversary)

or silver white dial with stainless-steel lacquered numerals (unlike the applied numerals featured on the limited 2019 releases) embossed Arabic numerals and a ring of smaller minute index markers circling the dial with Arabic numerals for every five minute increment.

There are two recessed sub-dials: a sub-seconds at the 6 o’clock position and a 30-minute counter at the 12 o’clock position.

Except for the 18k 5N red gold models, which consist of a slate colored dial option with black sub-dials;

plus another silver dial that varies from the steel version by using gold for its central hands, numerals and having slightly grayed sub-dials.


They all come equipped with perfectly proportioned feuille central hands that integrated harmoniously with all the other elements, in order to facilitate legibility and include an encircling precision scale.
