IWC’s purple Formula 1 chronograph pays tribute to Singapore after dark

Singapore’s Formula 1 weekend has always looked different.

Held beneath floodlights on the Marina Bay Street Circuit, the race transforms the city into a nocturnal spectacle of speed, heat and saturated colour. It is this distinctive atmosphere — and one of Singapore’s most important natural symbols — that has shaped IWC Schaffhausen’s latest motorsport-inspired watch.

The Pilot’s Watch Chronograph 41 Mercedes-AMG PETRONAS Formula One Team Edition introduces a deep purple dial to IWC’s Pilot’s Watches collection for the first time.

Rather than drawing directly from the race cars, the colour references the Vanda Miss Joaquim, the orchid recognised as Singapore’s national flower. Its vivid purple is paired with numerals, hour markers and luminous hands in the turquoise-green shade closely associated with the Mercedes-AMG PETRONAS Formula One Team.

A matching purple rubber strap completes what is easily the most colourful team watch IWC has produced during its long-running Formula 1 partnership.

A team watch made for the paddock

IWC has been the official engineering partner of the Mercedes-AMG PETRONAS Formula One Team since 2013, with dedicated team watches forming part of the relationship since 2022.

These editions are intended to be worn by mechanics, engineers and other team personnel trackside, as well as staff at the team’s headquarters in Brackley, England. That working role helps explain why the watches tend to prioritise low weight, durability and legibility rather than simply adding Formula 1 branding to an existing luxury timepiece.

For the new reference, IW388121, IWC has selected a 41mm case made from Grade 5 titanium. The metal is approximately half the weight of steel, resistant to corrosion and valued for its strength-to-weight ratio.

Its connection with motorsport is functional as well as thematic. Titanium alloys are used in Formula 1 components subjected to considerable mechanical and thermal loads. Most visibly, the protective Halo structure positioned above a driver’s cockpit is also manufactured from a high-strength titanium alloy.

IWC has given the case a brushed finish, retaining titanium’s understated grey appearance and allowing the purple dial and green details to carry the visual impact.

At 14.5mm thick, this is still a substantial sports chronograph. The reduced weight of the titanium case should, however, make it noticeably easier to wear over a full day than an equivalent steel model.

Familiar engineering beneath a new dial

Behind the colour is a familiar and proven mechanical package.

The watch is powered by IWC’s automatic 69385 calibre, an in-house chronograph movement built around a traditional column wheel. It operates at 28,800 vibrations per hour and provides a 46-hour power reserve.

Its chronograph layout places the elapsed-minute display at 12 o’clock and running seconds at six. The vertical arrangement has been a defining feature of IWC’s Pilot’s Watch chronographs for decades, keeping the displays clear despite the amount of information presented on the dial.

A combined day-and-date window sits at three o’clock, giving the watch additional everyday usefulness beyond its stopwatch function.

The movement is decorated with Geneva stripes and circular graining and can be viewed through the sapphire crystal caseback. Water resistance is rated to 10 bar, equivalent to approximately 100 metres.

The front is protected by convex sapphire crystal with anti-reflective treatment on both sides. IWC also secures the glass against displacement caused by sudden changes in air pressure, a feature associated with the collection’s aviation origins.

The purple rubber strap is fitted with IWC’s EasX-CHANGE system, allowing it to be removed without conventional tools. A titanium pin buckle maintains the lightweight construction.

The fourth Mercedes-AMG PETRONAS team watch

The purple chronograph is the fourth official team watch produced through the partnership.

The series began at the 2022 Miami Grand Prix with a titanium Pilot’s Watch Chronograph 41 distinguished by PETRONAS-green details. A more performance-focused Ceratanium chronograph followed at the 2023 Las Vegas Grand Prix, complete with a black ceramic tachymeter bezel.

In 2025, IWC changed direction with the slimmer, three-hand Pilot’s Watch Mark XX Mercedes-AMG PETRONAS Formula One Team Edition.

The new Singapore-inspired chronograph returns to the original 41mm format but gives it an unexpectedly expressive identity. It also arrives alongside a new Mercedes-AMG PETRONAS collection from team kit supplier adidas, extending the purple colour story beyond the watch.

For collectors, the appeal lies in that balance. The architecture of the watch is recognisably IWC: practical, engineered and highly legible. The dial, meanwhile, is considerably more adventurous than the black, blue and green treatments typically associated with modern pilot’s watches.

It is a tribute to Singapore that avoids obvious images of the skyline or circuit. Instead, IWC has used colour to capture some of the energy of Formula 1’s original night race — and created one of the partnership’s most distinctive watches in the process.

As I watched a Netflix show on Apple’s first foldable, the iPhone Duo, I had two surprising thoughts.

The first: Maybe I don’t need my iPad Mini anymore.

The second: Uh oh, am I about to spend $1,999 on a phone?

I didn’t think folding phones were for me. I’ve been testing Android versions from Samsung and Google since 2019, and those early editions came with too much screen and too many compromises.

Fast forward seven years, and the technology has come a long way. Apple—in its very Apple way—has also come up with some hardware and software trickery to make up for some shortcomings of the basic design. My desire for a folding phone before today was zero. After today, it’s a lot more than zero.

I’m not ready to recommend the Duo, which ships on Oct. 23, just yet. Not until I am able to test it more fully, so be on the lookout for that review in a few weeks. But from what I experienced at Apple Park on Wednesday, I could actually picture myself using this new half-phone, half-tablet hybrid.

Crease camouflage

For months, I’ve been using Samsung’s Galaxy Z Fold 8, a similarly squat, passport-shaped foldable that opens up to a larger screen. It’s impressively thin and can easily fit into the infuriatingly tiny pockets in women’s pants and dresses. Samsung did a lot of work to minimize the crease—the dip between the two halves of the big interior display—but it’s still clearly there.

When I held the iPhone Duo open, the crease was barely visible. As I slid my finger across the display, I could feel it, but it’s more subtle than Samsung’s. Most of the time, the screen looked as flat and smooth as the one on an iPad.

Apple employed both software and hardware techniques to camouflage the crease. The matte surface of the interior 7.6-inch screen minimizes reflections to hide it. (Samsung’s Fold 8 screen is shiny.)

And as you begin to open or close the iPhone Duo, the interface shifts the controls and content away from the center crease. If, say, you’re watching a video on the outer screen, you can open the Duo to switch to the bigger display within. A black fade marks the transition. You don’t see the video full screen until the phone is completely flat.

Heavy handed

My second observation was that, when the Duo is closed, in phone mode, it was harder to use one-handed than I expected.

In the keynote trailer and press release, Apple touted how thin the Duo is. It’s marketed as the thinnest iPhone ever—when open.

But it’s actually thicker and heavier than most of its Android competitors. The Duo weighs 254 grams, and is 11.3 millimeters thick when closed. The Samsung Galaxy Fold 8 is just 201 grams, with a thickness of 9.7 millimeters. Google’s Pixel 11 Pro Fold is 239 grams and 10.1 millimeters.

Because the Duo is also wider than a standard iPhone, I found it quite a challenge to type.

I admit, I do have smaller-than-average hands. So I consulted my colleague Rolfe Winkler, who has a larger grip. He agreed the Duo feels big.

Apple rearranged the interface on the outer screen so it looks different than traditional iPhones. The dock and control center are off to the right to be more reachable. Committing to the Duo as your main device will require adjustments in your handling. You will have to learn a new way to use and type.

Work and play

My most surprising takeaway? I feel a pull toward this device.

I always thought that combining an iPhone and an iPad would mean bigger compromises. The battery life is about the same as the 18 Pro (up to 24 hours of “regular use” on a single charge), though I’ll need to verify that in my real-world testing. And it’s also as durable, with the same IP68 dust- and water-resistance rating as the rest of the iPhone lineup.

There are trade-offs, for sure. Trying out the camera, I immediately missed the 8X zoom in my Pro model. The Duo has just 2X zoom, which wouldn’t cut it for the dozens of pictures I take of my kid every day.

But the dual screens unlock new photo functionality. You can see what your shot looks like from the outside screen. As someone who has tried tirelessly to self-direct a family photo—or a spouse—I am very eager to try this out more.

Foldables, I initially thought, were for classic mobile-warrior jet-setter types, who never sit at a desk and are always on calls. For that crowd, the Duo can run two apps side-by-side.

Me, I’m more of a bed binge-watcher and ebook reader. That’s what my beloved iPad Mini is for.

Watching videos on the Duo is a nice experience—nice enough that you forget the screen is 0.7 inches smaller than the iPad Mini’s. The main screen is also a 4:3 aspect ratio. Very similar, by the way, to the IMAX edition of the Odyssey.

Because I wasn’t able to snag a ticket to one of the sold-out screenings, I will be watching Christopher Nolan’s version of Homer’s epic on the Duo, just as the director intended. (Just kidding! Sort of.)

The Duo costs $800 more than an iPhone 18 Pro, and I’m not sure I want to spend that premium on a first-generation Apple device. But I’m not ruling out the idea that a Duo might one day be in my future. Stay tuned for my full review.
