Why My First Speedmaster Had To Be The Calibre 321 Fratello
Feb 10, 2026

Why My First Speedmaster Had To Be The Calibre 321

Having been a part of the Fratello team for more than five years, I suspect some people might find it mildly shocking that it’s taken me this long to add a Speedmaster to my collection. With Fratello being so closely associated with the mighty Speedy, not owning one almost felt sacrilegious. The truth is simpler.

Finnish Finishing: Kortela Valta Unveils the Toka SJX Watches

Finnish Finishing: Kortela Valta Unveils the Toka

The Toka from Finnish duo Roope Kortela and René Valta reflects the ongoing appeal of beautifully finished, time-only watches, combining a thoughtfully reworked historical calibre with the brand’s first champlevé enamel dial. With an emphasis on high-grade finishing and increasingly in-house components - including a proprietary free-sprung balance - the Toka is a strong sophomore effort from the startup independent. Rene Valta (foreground) and Roope Kortela Initial thoughts It’s been more than 25 years since Philippe Dufour unveiled the Simplicity, a watch that challenged prevailing wisdom about what fine watchmaking was all about. Launched at a time when brands and collectors were focused on complications, the Simplicity arguably created the niche for highly finished time-only watches and intensified collector focus on independent watchmaking in general. Though the field has become crowded over the past quarter-century, collector demand has proven durable. The Toka is a watch built in this tradition. The Omega calibre inside the Toka has been heavily reworked by Kortela Valta. The watchmakers kept most of the original architecture intact, while applying high-end finishing top to bottom. Furthermore, since the start of 2025, the watchmaking duo has expanded the list of components they’re able to make in-house, including the new free-sprung balance that differentiates the Toka from the Eka and Oma models that preceded it.  The Toka features a fairly traditional...

Hands-On: The New Omega Speedmaster Grey Side Of The Moon With Caliber 3869

Apollo 8 was the first space flight to reach the Moon. On board were NASA astronauts Frank Borman, Jim Lovell, and William Anders. It took them 68 hours to travel to the Moon, and during the first 66 hours, the spacecraft’s windows were facing Earth. Apollo 8 needed to swing behind the Moon (in total, […] Visit Hands-On: The New Omega Speedmaster Grey Side Of The Moon With Caliber 3869 to read the full article.

Record Breaking Konstantin Chaykin ThinKing Debuts at Auction SJX Watches
Patek Philippe Calibre 89 ref 989J May 2, 2025

Record Breaking Konstantin Chaykin ThinKing Debuts at Auction

If you want to own the world’s thinnest mechanical watch, the Konstantin Chaykin ThinKing, you’ll have to fight for it at The Geneva Watch Auction: XXI, which will see the first production example go under the hammer. The 1.65 mm stature of the ThinKing is even more impressive coming from a small Russian independent watchmaker, considering previous records were set by big Swiss brands ranging from Piaget to Richard Mille. Notably, this is not the first time a landmark release has been trusted to an auction that isn’t linked to a charity. The most famous example of this was the Patek Philippe Calibre 89 (ref. 989J) back in 1989 at Antiquorum’s thematic sale. The ThinKing will be sold in the first session of the auction, which starts on May 10, 2025, at 2 pm. The ThinKing in profile. Image – Phillips Mr Chaykin achieved the record-setting height with clever construction, including a “double balance wheel” system that places an intermediate wheel between the balance and escapement, allowing both to sit on the same plane. Another notable technical feature is a barrel that is open on both sides, and no thicker than the mainspring itself. And unlike most serially-produced Konstantin Chaykin watches, each ThinKing is made, finished, and assembled by Mr Chaykin himself. Wearability is enhanced by the bolt-on protective shroud in titanium christened “PalanKing”. This increases the height to 5.4 mm, but adds key-less setting and winding, and automatic winding by a...

Breitling Introduces the Top Time B01 Racing Chronograph with a Little Help From an Automotive Icon Worn & Wound

Breitling Introduces the Top Time B01 Racing Chronograph with a Little Help From an Automotive Icon

While more marketable leagues like Formula 1 entice with hypercars, social media presence, and reality TV, rally racing continues to wow spectators with its gritty and furious breed of off-road motorsport. Still, the rally world isn’t without flashes of luxury, and Breitling’s three new Top Time B01 Racing models look to celebrate the sport in all its dirty, dangerous beauty. Fortunately, the Swiss brand has a wealth of innovations to pull from their Top Time line-most notable is the “dashboard” dual-chronograph dial design that helps give the new Racing models that rally-inspired edge.  All three Racing models are anchored by a stainless steel cushion case that gives the watch a squared-off and recognizably retro-futuristic look. With a 38mm diameter and a 44.4mm lug-to-lug measurement, the Top Time Racing should wear comfortably on most wrists but remain legible-both important factors to consider in motorsports, where one wasted second could spell disaster (or mortal danger). Raised, grooved sections add texture and dimension to each rounded corner of the case and mirror the tight spacing of the ¼ second dashes around the dial. All three models feature perforated calfskin straps nestled within an 18mm lug width, a design that calls to mind vintage racing gloves but still emphasizes durability and sportiness.  The aforementioned “dashboard” dual-chronograph dial mimics an instrument cluster, with “squircle” (yes, Breitling does call them that) subdi...

[VIDEO] Grand Seiko Redefines Accuracy – Again: Introducing the 9RB2 U.F.A. Spring Drive Caliber

2022: the Kodo constant force tourbillon. 2023: the Tentagraph hi-beat mechanical chronograph. 2024: the 9SA4 manual wound, hi-beat, dual-impulse escapement caliber, and Kodo Daybreak. It’s easy to forget that Grand Seiko has brought the proverbial heat to Watches & Wonders every year since the fair started, unveiling something that one could call “revolutionary” for the brand, if on varying scales. Well, it’s looking like 2025 will continue the trend with the introduction of Spring Drive Caliber 9RB2, the first caliber with U.F.A., or Ultra Fine Accuracy, designation. Before proceeding, there are two important concepts to understand: Spring Drive and Grand Seiko’s history with acronyms (which, if you know, feel free to jump two paragraphs ahead). Starting with the former, the elevator pitch, which I will take from our article dedicated to the topic is “Spring Drive combines the best of mechanical watchmaking and the best of quartz timekeeping to create a state-of-the-art caliber that lacks the weaknesses inherent to both of these movements.” A bit deeper, Spring Drive movements use the energy stored in a traditional mainspring to drive their proprietary “Tri-synchro” regulator, which replaces the classic lever escapement. It consists of a glide wheel, the rate of which is controlled by an electromagnetic brake, and is essentially regulated by an integrated circuit with a quartz oscillator. The result is a mechanical movement with quartz-like accuracy and...

[VIDEO] Review: the echo/neutra Rivanera

Over time, I’ve come to realize that my favorite emotion to experience in this hobby is surprise. That could be because I work in the watch industry and am therefore exposed to so many watches that are the opposite of surprising. Predictability, in any job, leads to a certain amount of drudgery. But those moments of surprise, seeing or reading about a watch that you didn’t expect or couldn’t have conceived of, more than make up for it.  By the same token, I understand that for some in our community, surprise or any rocking of the boat is less desirable. If you view watches from a strictly classicist perspective, you might roll your eyes at purely adventurous designs in the same way I do at watches that seem to just be repeating what has come before. Part of me, I have to admit, envies the watch enthusiasts who can see a vintage inspired, black dialed dive watch and be ready to throw the rest of it away. There’s an idea that I keep turning around in my head, that watches were never really intended to be “collected,” that one good one is all anyone really needs, so there’s something correct about seeing a watch like a Tudor Black Bay (a watch I own and love, and even won a Thunderdome with) and feeling like you’ve just a met a watch that will be with you forever.  At this point, that’s just not me, and I find myself seeking out watches that feel obscure, strange, or neglected somehow. I want to discover new, under the radar, and risky designs made by crea...

If 100 people were asked about the first words that come to mind when “Audemars Piguet” is spoken, I wager that almost all would respond with “Royal Oak.” That signals how popular Gérald Genta’s groundbreaking 1972 design has become. However, before this and even after the Royal Oak was released, Audemars offered a very different […] Visit In-Depth: The Audemars Piguet 5043BC “Ultra-Thin” And Caliber 2003 to read the full article.

Hands-On: MB&F; HM8 Mark 2 in Blue CarbonMacrolon SJX Watches
Girard-Perregaux calibre has been MB&F;’s Apr 25, 2024

Hands-On: MB&F; HM8 Mark 2 in Blue CarbonMacrolon

MB&F; has released the third instalment of its automobile-inspired wristwatch, the HM8 Mark 2. Now in blue CarbonMacrolon, the latest HM8 Mark 2 follows on the green and white iterations introduced last year. Inspired by 1970s sports cars like the Lamborghini Miura, the new Mark 2 retains the model’s signature speedometer-like display for the time and “double bubble” sapphire crystal. Although the CarbonMacrolon panels of the case are also found on earlier versions, the material has been tweaked to incorporate ingredients also found in automotive paint, giving the case a metallic, sparkly blue finish resembling a car’s paintwork. Initial thoughts Though only a cosmetic update to the model, the latest HM8 Mark 2 is the most striking to date. Though the change of colour might seem like a trivial matter, the new paintwork is a perfect complement to the styling and concept of the watch – the metallic finish really does evoke the paintwork of a high-end automobile. Interestingly, the new Mark 2 feels sleeker than the earlier versions thanks to the paintwork, even though the watch is identical in dimensions and form. The rest of the watch is identical to the standard version, and the same movement is visible in the “engine bay” through the sloping sapphire crystal. The Girard-Perregaux calibre has been MB&F;’s base movement of choice almost since its founding two decades ago, so something more interesting would be a useful upgrade, particularly since the movement i...

Our Morning with Cartier Worn & Wound
Patek Philippe Cartier can be thought Apr 12, 2024

Our Morning with Cartier

There’s really nothing like the Cartier meeting at Watches & Wonders. Along with Rolex and Patek Philippe, Cartier can be thought of as an anchor brand of the show. They have one of the largest booth spaces, with nonstop foot traffic, and a veritable army of cheery employees who are happy to show you watch, after watch, after watch in your meeting. It’s a seemingly never-ending parade of beautiful objects. To me, that’s what an event like this is all about. Why are we here if not to gawk? In terms of sheer volume, Cartier is your best bet for that.  What’s wonderful about Cartier, though, is that the beautiful objects aren’t necessarily completely unobtainable, and the brand works hard to make even the most head turning pieces feel approachable (at least in the context of the show). While you’ll see your fair share of unique pieces and watches that have no listed price because if you have to ask, well, you know how it goes, there are accessible ways into the brand that give you plenty of what is essential about Cartier.  My favorite example of this for 2024 is a new dial variant for the Santos, in a metallic brown with a gradient effect. It’s lovely, and pretty clearly meant to evoke something that has aged naturally over a period of many years. It’s available as both a large and medium Santos, but it’s very clear that the medium is the “correct” size for this watch. It works considerably better when it’s a little more discreet.  It joins a growi...
