I kept going back to the Sero Signature more than I expected, and that’s a huge compliment. It’s one of those watches that only starts to make sense once you begin placing it against other things you already know, once you start measuring it mentally against references that defined this category in the first place. Not to say that it’s « du vu et revu » as in something we’ve seen before, but to hammer down my point that there’s a clear respect of the traditional way of doing things.

Because whether Sero intended it or not, this watch lives in a space that’s already been written. You don’t approach Breguet numerals, a slim manually wound profile, and a restrained case without inevitably entering the orbit of watches like the Patek Philippe Calatrava ref. 96, the Vacheron Constantin ref. 6073, or even more modern reinterpretations like the F.P. Journe Chronomètre Bleu. Different price brackets, different intentions, but the same underlying language. Again, a compliment.

And that’s where the Signature becomes interesting. Not because it competes with those watches (it doesn’t) but because it clearly understands the framework they established.

The case proportions are the first indicator. 37.5mm is the easy number to read (sweet!), but the 46.5mm lug-to-lug is where the watch really positions itself. It stretches just enough to avoid that compact, almost fragile stance you get with smaller Calatrava-style pieces. It wears more like certain oversized references from the 40s, where lugs carried more visual weight and extended the watch across the wrist. It’s a subtle shift, but it changes the entire posture of the watch.

The 9.5mm thickness is exactly where it should be, and that’s largely due to the Sellita SW210-1. There’s nothing mind blowing about that movement, but from a construction standpoint, it’s coherent. Around 3.35mm in height, manual winding, stable architecture. It allows the case to remain slim without forcing the watch into ultra-thin territory, which often introduces compromises in durability or water resistance; AKA having to take it off to wash your hand. The 100 meters rating here is not just a spec, it tells you the case has been built with actual use in mind. 

But to get into the main part, the dial is where Sero takes a more deliberate position.

Engraving the numerals directly into the dial instead of printing or applying them changes the reading entirely. From a horological perspective, you move from surface decoration to taking away from the material itself. The numerals exist as negative space, and that means light behaves differently. You don’t get the crisp contrast of printed lacquer or the shadow line of applied markers. Instead, you get something more variable, more dependent on angle and intensity.

This is closer, in spirit, to how traditional guilloché dials interact with light, although achieved through machining rather than hand-turned patterns. The vertical brushing underneath adds a directional grain, which keeps the dial from becoming too static while maintaining control over reflections. It’s a measured approach. 

The consistency of execution is what stands out here. The chemin de fer, the numerals, even the signature text all follow the same engraved logic. That avoids the common issue where different techniques compete on the same dial, printed tracks next to applied markers next to stamped logos. Here, everything is resolved within the same surface.

The handset is another area where the watch holds together, and honestly the first thing I noticed. Heat-blued spade hands, correctly dimensioned, doing exactly what they’re supposed to do. The minute hand reaches the track with precision, which is something you’d expect, but not something you always get. The hour hand sits cleanly within the numeral ring, and the seconds hand remains visually light. 

It’s basic watchmaking discipline, but it’s often where watches lose coherence.

Looking at the different dial configurations, the variations don’t try to reinvent the watch. The silver and champagne dials stay closest to classical references, where the engraving becomes more subtle and the watch reads almost like a study in restraint, to be a little more poetic. The blue dial increases contrast and sharpens the overall presence, pushing it slightly closer to contemporary tastes.

The red dial is the outlier, but it still respects the underlying architecture, which keeps it from feeling disconnected. A little different, but different strokes for different folks.

Now, where the Signature really needs to be placed is in its price segment. At around €1,100 to €1,200, it sits in a very competitive space. You’re looking at watches like the Nomos Tangente, the Longines Heritage Classic, vintage Omegas…

Most of those watches take a different route. Nomos focuses on Bauhaus minimalism and in-house calibres, Longines leans heavily into archival design, vintage Omega Genèves are iconic and reliable. Sero doesn’t really sit directly with any of them. It’s closer to what smaller independent or collector-driven brands have been trying to do in recent years, tightening classical codes rather than reinterpreting them.

That’s also where the watch finds a bit of cultural relevance. There’s been a clear shift in the last few years, especially among younger collectors, away from oversized, overly expressive pieces toward something more controlled. Not necessarily vintage, but informed by it. The Signature fits into that movement as a very clear participant.

That doesn’t make it perfect. The “Signature” text still feels slightly more present than it needs to be when you look at how low-key everything else is, and the longer lug-to-lug will not work for every wrist. But when you place it where it actually belongs, within that €1,000 segment, against watches that often get one or two things right and miss the rest, the Signature holds together in a way that’s harder to dismiss.

What was interesting, and something that came up in conversation with Sergino, the founder, after I shared my thoughts, is that none of this is accidental. The positioning, the proportions, even the way the watch sits in this slightly uncomfortable but very deliberate space, it’s all been thought through.

And that also reflects in how they’re bringing it to market. The initial presale starts just under the €1,000 mark, with the first pieces at €899 before taxes, then €999 during the two-week window, before settling at €1,199 retail. It’s a detail worth mentioning because, at that earlier entry point, the watch shifts slightly in how you evaluate it. You’re no longer just comparing it to its immediate peers, you’re looking at it against a much broader field, and in that context, the level of attention given to proportions, dial execution, and overall coherence becomes harder to overlook.

If I were to discribe it in 1 word, I’d say traditional.

There are some projects I cover for Time Telling Magazine because they are interesting, and others because they feel like an ongoing conversation between me and the people behind them, and this one definitely belongs to the second group. Especially because it sits in a place I personally love, a place where Arabic artistic identity meets European watchmaking know-how (le savoir faire), and I always feel like that combination creates something that feels both ancient and modern at the same time. Whenever Abdulaziz and Arnaud work together, it feels like two worlds meeting somewhere in the middle, one driven by emotion and language, the other by precision and craft, and I think that is exactly why I naturally found myself pulled into this new story (again).

So when Abdulaziz told me about this new watch, he started the story very casually, the way he always does. He said his brother in law is the typical tech person who loves devices and numbers, but really hates having anything on his wrist. Nothing at all. Which already makes the idea of building him a watch kind of funny. But before his birthday, Abdulaziz’s sister told him she wanted a watch made specifically for her husband. Not bought, made. Something personal enough that even a person who does not like watches would probably wear it anyway. I immediately understood what she meant because their relationship has this warm and positive energy that you can actually see.

Their family even has a phrase that belongs to them. They always say “أبرك الساعات”, and for anyone who does not speak Arabic, it means something like “the luckiest hours” or “the most blessed moments”. It is the short version of another phrase they say, “أبرك الساعات اللي شفتك فيها”, which means “the most blessed hours are the ones in which I saw you”. It is one of those lines that becomes part of a couple’s identity, very natural, sentimental in an effortless way, and extremely personal. That is why Abdulaziz placed the short version on the dial. It belongs there. It carries their warmth.

Since the phrase needed to look as meaningful as it sounds, he asked Jassim Alnasrallah to write it. If you know Jassim’s style, you already understand why he is the right person. He writes calligraphy like he is building a structure. He chose Thuluth script, which has a formal and elegant tone, and he composed the words in an oval shape that guides your eyes naturally around the dial. Even the tiny details, like the dots and the little hamza and the miniature kaf (look these up), were arranged so that they line up symbolically with the main hours on the watch, meaning three, six, nine and twelve. It’s the type of detail no one notices unless someone points it out, but once you know it, you feel the intention behind it.

Then the whole thing went to Arnaud from L’Artisan Horloger, who now knows exactly what happens each time Abdulaziz brings him a new idea. The first thing he told me was that this was his first experience with something like this, and that it was eye opening, that Abdulaziz always pushes him to new places. 

They are actually developing four different stone dial variations for this calligraphy collection (hence my journalistic involvement), Lapis Lazuli, Meteorite, Tahitian mother of pearl with a blue tone, and white mother of pearl. 

The calligraphy itself is laser cut in a very thin stainless steel, brushed so it has texture, and it is extremely delicate. Arnaud told me it was the most fragile and meticulous part he has ever worked with, especially on the meteorite dial which has an uneven surface that makes everything more difficult.

Inside, they used the Miyota 9015, which beats at four hertz, has hacking seconds, and is accurate and reliable. It is a nice upgrade compared to the usual entry level movements people expect, and it fits the whole spirit of the watch, which is emotional on the outside and practical on the inside.

Before we finished our conversation, Abdulaziz told me to share one last message with my readers, and he insisted on it. The calligraphy watch is now available for order! 

Anyone who wants one can contact Arnaud directly, either on the website or through the brand’s Instagram. It is not a mass piece, it is simply the continuation of the creative relationship I have been lucky enough to witness up close.

And that is honestly what I enjoy most about writing these stories. The watches are beautiful, of course, but it is always the people and the emotions behind them that stay with me the longest.
