Two editors. Two wrists. One spectacular collection. United by a love for the Cubitus from Patek Philippe, we debate the watch in the original and medium sizes.
When Patek Philippe unveiled the Cubitus last year, it made a bold statement with the launch of the 45mm version—a daring size that instantly captured attention for its striking architectural presence and modern flair.
This year, at Watches and Wonders, the collection grew with the addition of a 40mm version, offering a more classic and versatile alternative. Naturally, this sparked plenty of conversation among watch enthusiasts—including right here at Tatler GMT.

One of us champions presence: a watch that commands attention across the dinner table. The other favours proportion, believing that elegance is best expressed in subtler, measured tones. So, in the spirit of good fun (and a healthy editorial rivalry), we decided to put our preferences on the page.

What was your initial reaction when you saw the Cubitus?
Edgar Chang (EC) When I first saw the Cubitus last year, I was immediately drawn to its groundbreaking design. It echoes a Gérald Genta creation but with a fresh, modern twist—a bold move for a brand with over a century of heritage. Some collectors might see this approach as lacking sincerity, but the willingness to try something new is commendable.
Annabel Tan (AT) I attended the Cubitus launch in Munich last October and was pleasantly surprised by how well it wore on the wrist. Admittedly, 45mm is large by most standards—particularly for Asian wrists, and even more so for women—but the proportions just worked. It sat beautifully, and the design felt balanced and refined.
I appreciated that the Cubitus marked a bold new direction for Patek Philippe with its first square-shaped case with rounded corners, a departure from the brand’s more traditional silhouettes. The 45mm version had real presence: substantial, confident, and elegant in the way only Patek Philippe can manage.
Some say 45mm is bold, others say 40mm is timeless. What do the different sizes say about the wearer?
EC Comfort will be key for many. With my relatively slender wrist, the 40mm is noticeably lighter and a better fit. It’s perfect for someone like me who prefers to keep a low profile
AT [The 45mm] says the wearer is self-assured, contemporary, and unafraid to challenge tradition. She appreciates Patek Philippe’s history but isn’t stuck in it.

Which size wears the Cubitus design best, and why?
EC To be honest, the 45mm case does a great job showcasing the watch’s architectural lines. That. said, the 40mm version doesn’t fall. short; in fact, it feels more refined and evokes a sense of understated elegance.
AT Architecture deserves space. The faceted structure, the interplay of light and shadow, the bold dial—they all come alive at 45mm. It’s like viewing a sculpture from the right distance; the scale lets the design breathe and assert itself.
Of course, the 40mm may be more practical for some wrists, but on mine, the 45mm feels right at home. It wears like it was meant to—bold yet refined. It’s surprisingly well-balanced. Thanks to the ergonomic lugs and slim profile, the 45mm is flatter than you’d expect.
Which version makes a bolder statement, and is that a good thing?
EC While the 40mm is sufficient to express the design concept, the 45mm version is undeniably more eye-catching. Whether making such a bold statement is a good thing depends on the wearer’s personality.
AT No question, the 45mm. And in the realm of sporty-elegant timepieces, that’s a very good thing. The Cubitus isn’t meant to fade into the background. Its bold geometry and angular case deserve to be seen. The 45mm version amplifies that design language.

Do you think it was a good idea to offer the Cubitus in two sizes?
EC Most brands are downsizing their cases, likely in response to market feedback. The introduction of the 40mm keeps pace with this trend of prioritising comfort through smaller cases.
AT Patek Philippe knows its audience is evolving. Some are purists, others want contemporary flair. Offering both sizes shows they’re listening, while staying in control of the narrative. Launching the 45mm first was the right move. It created immediate impact and set the tone for what the Cubitus represents: bold design, architectural expression, and a fresh chapter for the brand. It captured attention from the outset, paving the way for the more classic 40mm to follow with quiet confidence.
Would you wear the Cubitus every day?
EC Its exquisite craftsmanship, understated style, and comfortable wear would make it my top choice for daily use.
AT Yes, in a heartbeat. It’s comfortable, and the sporty yet sophisticated design makes it incredibly versatile. It pairs effortlessly with everything, and its visual presence instantly elevates even the simplest outfit.
How would you recommend the Cubitus in your preferred size to a first-time Patek buyer?
EC To truly enjoy a watch, comfort is key, and the 40mm fulfills that.
AT If you’re entering the world of Patek Philippe through the Cubitus, you’re clearly not here for a Calatrava. You’re after something different—something architectural, avant-garde, and future-facing. The 45mm delivers exactly that.
