Insight: Regulating a Mechanical Watch Movement
A mechanical watch is not always spot on; less-than-perfect timekeeping can happen, often due to an unruly oscillator. The solution is direct adjustments to the hairspring and balance assembly, either slowing down or speeding up the oscillator, a practice known as regulation. Watchmakers have devised multiple innovations to achieve this, including the free-sprung balance, exemplified by the Gyromax of Patek Philippe and Microstella of Rolex. While a simple concept in principle, the mechanics and practice of regulation are nuanced. Here we’ll delve into the theory of regulation and the primary regulating systems: the curb-pin regulator and the free-sprung (or variable inertia) balance. The Lange L043.4 with a screwed balance inspired by pocket watches Basic concepts In order to better understand watch regulation, we need to first cover some of the basic physics behind the watch oscillator: The component responsible for the running rate of a movement is its regulating organ. The regulating organ is made up of a hairspring paired to a balance, which together are also known as a harmonic oscillator. The natural oscillation period is the time it takes the balance to make a full swing, back and forth. The period is made up of two vibrations, one for each direction of the balance motion, with the escapement being unlocked at each vibration. Notably, the natural period of a balance wheel is intrinsic to itself and does not depend on the escapement type or the going train ratio. ...

Havid Nagan Comes of Age with the Classic One
Having made its debut two years ago with the Schwarz Etienne-powered HN00, Havid Nagan returns with Classic One, a chronometer-certified dress watch with a multi-layered dial. Available in two dial finishes, ebony or ivory, the Classic One takes the nascent brand in a new, more traditional direction. The Havid Nagan brand was launched on Kickstarter in 2019 by Aren Bazerkanian, who at the time was working as Director of Operations at the FP Journe boutique in Los Angeles. One of the guiding principles of Havid Nagan is an emphasis on slimness, which is an obsession that Mr Bazerkanian picked up from his time working for Mr Journe. Initial thoughts The original HN00 and subsequent HN01 were thoughtful and appealing watches, but the Classic One feels like a more mature product. In my opinion, the debut models were a bit overambitious with their proprietary strap system, which, though sleek and attractive, result in the risk of not being able to find replacement straps in the future. The Classic One, on the other hand, is more traditional in its construction, with classic lugs that can accommodate a variety of straps (the watch comes standard with straps from Jean-Rousseau). As a result of being more classical in orientation, the central feature of the Classic One is its multi-part dial with an unusual construction made up of clear sapphire sandwiched by brass discs. Finished with applied Calatrava-style hour markers, the overall effect is dynamic and attractive. In terms of...

The MoonSwatch '1965' Review
If you’re a Speedmaster fan, you know the story. NASA sent out an RFP for an official watch of the space program – a watch that would undergo a litany of tests (pressure, temperature, corrosion resistance, shock, acceleration, and vibration to name more than a few) to prove that it could withstand the rigors of space exploration. Three watches came in for testing: A Longines Wittnauer 235T, a Rolex Daytona Ref. 6238, and an Omega Speedmaster ST105.003 dating to 1964. As you know, the Speedmaster won the contract and on March 1, 1965, it became the aforementioned official watch of the space program. That designation has since been engraved on the caseback of every Moonwatch in production today. This week, the Swatch Instagram account was buzzing with retro video content that would always end with a title card reading “1965.” Today, we know why. Celebrating 60 years since the flight qualification of the Speedmaster, and nearly 60 years from the moment Ed White took a Speedy for a 20-minute space excursion during Gemini IV, Omega and Swatch have announced a celebratory MoonSwatch that marries the past to the present. The first thing you’re going to notice is the white dial, a detail that harkens back to Snoopy MoonSwatch, but more importantly, to the 2024 White Speedmaster that set the watch world on fire after DanielCraig wore it to Planet Omega in New York in 2023. For all of you who wince at the sight of yet another MoonSwatch – and there are plenty of you – ...

Hands-On: the TUUL Filthy 13
It’s hard to deny the outward appeal of a field watch. Tactical but not overly macho, mature but not boring-the traditional field watch “style” is eminently wearable for combatants, explorers, mountaineers, and the regular old civilian crowd. Classics like the Hamilton Khaki Field, Bulova A-11 “Hack”, Seiko Alpinist, Rolex Explorer, and many, many more, are icons of the category, and it’s hard to feel like there’s much more to be innovated or improved upon. The TUUL Filthy 13 is keenly aware of the history of the field watch. Its very name is a derivation of the “Dirty Dozen”-both the 1967 war movie about a squad of delinquent soldiers, and the twelve Swiss watchmakers commissioned to build a watch to help win World War II for the Allied forces in 1945. The Filthy 13 is a reference to Private Jake McNiece, the thirteenth member of the real-life military unit, left out of the film based on the squad’s feats-a cheeky signal of the Brooklyn-based company’s dedication to preserving the history and resilience of the field watch, while carving their own convention-breaking niche. I was given the opportunity to test out the Filthy 13, and was immediately drawn in by the well-laid out history and inspiration behind the watch. My first field watch was a Timex Weekender Indiglo given to me by my grandfather-a watch I still have and wear frequently-and I regularly pine after the Hamilton and Seiko 5 lineups. At first glance, the Filthy 13 is a well...

Hublot’s Latest SAXEM Release is a Green Big Bang Tourbillon Automatic
While I haven’t been doing “this” as long as some who have been in the watch media trenches since a time when you could reliably get a discount on a brand new Rolex at an authorized dealer, I’ve been doing it long enough to get a sense of the rhythms of a new release season. We are, as of yesterday, in the thick of it. LVMH Watch Week is the unofficial (but also kind of official) kick off of a new year in novelties from big luxury group brands, and within the confines of the LVMH experience there’s one tradition that stands out to me that’s become something I look forward to and get genuinely excited about: seeing what kind of crazy sapphire or SAXEM cased watch Hublot has come up with. Pretty reliably, on a year to year basis, Hublot shows us a wild and colorful and extremely expensive watch in an exotic, glass-adjacent material. This year, like clockwork, they’re back with the Big Bang Tourbillon Automatic Green SAXEM, a watch whose name is nearly doing my job for me. I’ve made no secret over the years of how much I enjoy these oversized, translucent watches. If I had to pick a favorite, it would probably be the purple sapphire Big Bang Tourbillon from 2022, but I’ll thank you in advance for not actually making me choose, because frankly these watches all do their thing equally well, and choosing the one you like best is like picking your favorite Coen Brothers movie. Some days it’s Fargo and on others it’s No Country for Old Men but maybe on Sunday...

TAG Heuer’s Long Awaited Formula 1 Update is Here
Was there ever any doubt that this was where this year was headed? Ever since it was announced that LVMH, and specifically TAG Heuer, would be taking over Formula 1 timekeeping responsibilities from Rolex as part of a broader 10-year partnership between the two, it was clear that 2025 would (for TAG Heuer) be all about racing. We just didn’t know what that would look like, at least when it came to the watches. Now we do, and surprise, surprise, TAG Heuer is kicking it off with a brand new generation of (what else?) The Formula 1 Chronograph. Motorsport and TAG Heuer have long been linked (something Zach recently explored), and one obvious example of this is the Formula 1. TAG Heuer launched the first generation of the Formula 1 way back in the ‘80s, and the simple, colorful, quartz watch helped to clearly establish a new sensibility for the brand. Since then, the Formula 1 has evolved, eschewing the almost toy-like quality of the earliest releases to bear the name and moving upmarket while still acting as the clear entry point into the brand’s chronograph offering - a quartz Formula 1 can still be had for under $2000, an almost shocking price tag in the context of the modern market. These new Formula 1s are a decided step up from those watches but still come in under the price of the latest generation of Carrera chronographs. The watches themselves are bold and clearly represent a step into a new generation of design language for the Formula 1 - a refreshing chan...

The Least Expensive Panerai Watches
Panerai might be the most in-your-face example of the quintessential Tool Watch That Made Good as a Luxury Item. Unlike many other contenders for that title, a Panerai watch today looks essentially the same as it did back in the 1940s, when Italian navy frogmen wore them into underwater combat. Few concessions have been made to modern tastes and trends: the luminous material on the dials is no longer radioactive (inarguably a positive change), Rolex no longer makes the cases, and you no longer have to be a naval commando to own one, but otherwise the relatively few models that make up the Panerai family have stubbornly adhered to their military-issue origins. It is this adherence that makes Panerai, for many, an all-or-nothing proposition — either you’re in the brand’s worldwide, rabid coterie of fans and collectors, proudly self-dubbed the Paneristi, or you roll your eyes at the notion of ever owning one: they’re too big, too flashy, too clunky, too Stallone. This article, the latest in our series of Price of Admission guides, is aimed at those aspiring to join the former group — in other words, those wishing to pull the trigger on their first Panerai but possibly intimidated by the breadth of choices — and, of course, by the ticket price for entry to that first tier of Paneristi-land. Without further ado, let’s find the most affordable Panerai watches in each of the current product families. RADIOMIR The Radiomir, first conceived in 1935 but tracing its m...

Year in Review: Eight Predictions for 2025
Twenty twenty-five will be shaped by several factors, ranging from major anniversaries for a trio of important high horology brands, to economic reality where the slowdown in demand will reshape retail channels (and already led one watch brand to go bust). And the coming year will also see the still-unknowable Rolex strategy unfold, which might happen under the radar but will definitely be interesting. Big watches for a big year Next year will be a milestone for trio of important brands. Audemars Piguet (AP), Breguet, and Vacheron Constantin (VC) will all mark significant anniversaries: 150 years at AP, 250 years of Breguet, and 270 years for VC. This implies some major timepieces or even mechanical objects are on the way. Such watches are practically convention as landmark anniversaries are often platforms for brands to launch major watches. Some of the most complicated watches in contemporary watchmaking were anniversary creations – Patek Philippe marked 150 years with the Calibre 89, and then 175 years with the Grandmaster Chime. The Patek Philippe Calibre 89 launched in 1989 for its 150th anniversary. Image – Patek Philippe Museum In 2005, when VC marked its 250th year, it launched the Tour de l’Ile, which was the most complicated wristwatch in the world at the time, and also the most expensive wristwatch sold at auction that year. With that in mind, VC might be working on something that lives up to its status as a maker of haute horlogerie complications. The Vac...

Zenith Looks to the Jungle for a Wild New Limited Edition Defy Extreme
One of my favorite pastimes within the world of watch enthusiasm is to tell anyone who will listen that the “Leopard” Rolex Daytona is my favorite version of the storied chronograph. When the Daytona comes up in conversation (and it does, a lot) I’m always ready to share that the intricate gem and diamond set version inspired by leopard prints and favored by Nicolas Cage is my favorite example. This assertion is only half a joke – I really do admire craftsmanship inherent in these watches (which is somewhat uncommon for Rolex) but mostly I like that the watch exists as a transgressive alternative to the norm. And what better way to do that than with a watch inspired by big cats and the jungle? The new Zenith Defy Extreme Jungle, a watch which immediately made me think of my favorite Daytona, knows that there is, in fact, no better way to gently push on the expectations of the typical watch enthusiast. There’s an important distinction to be made between this new watch from Zenith and the Daytona, and that’s that the Leopard Daytona is, in every way, an outlier in the Daytona collection and for Rolex as a whole. The Zenith Defy Extreme, and the Defy line more generally, are made up almost entirely of outliers. In other words, it’s not actually that strange to see a jungle inspired Defy Extreme when we’ve already seen high concept Defys taking on various themes over the course of many years. This isn’t even the first time Zenith has played with the “jung...
