Automatic Attraction: Corum Debuts New Golden Bridge Automatic At BaselWorld 2013

Something old, something new –that’s the theme that runs through much of watchmaking.  Lest we forget, the basic technology of watchmaking consists of a mainspring barrel, gears, a lever escapement, and a temperature compensated balance controlled by a balance spring.  All of those elements –every one –were in place by 1750, boys and girls, when […]

Cartier Chronographs; Two Watches, One Heart

Chronographs are probably the most popular complication. They are pretty affordable (for a complication) masculine and have a sporty appearance that most men like, weather we’re talking mono poussoir chronographs or the three button chronographs, it’s a type of watch that we find in almost any watch collection. Cartier has currently two interesting chronographs in […]

Promiscuous Wrist: Girard-Perregaux 1966 Minute Repeater, Annual Calendar & Equation Of Time Revolution

Promiscuous Wrist: Girard-Perregaux 1966 Minute Repeater, Annual Calendar & Equation Of Time

Despite the fact that the Promiscuous Wrist, by definition, gets around a lot, it (or I, I should say) has never had the chance to test-drive a watch with an equation-of-time complication. For that matter, we’ve never had a run around the block with an annual calendar either. So, when the chance came to kill […]

In-Depth: Understanding Resonance in Watches SJX Watches

In-Depth: Understanding Resonance in Watches

Resonance watches are among the most elusive machines in modern watchmaking. Creations such as F.P. Journe’s Chronomètre à Résonance perform well at auctions, commanding high prices. While their rarity and appeal are undeniable, watches that purport to harness resonance tend to be viewed with a degree of skepticism. A measure of skepticism is understandable - the concept of sprung balances becoming almost magically coupled is anything but straightforward and requires a profound understanding of oscillators in general.   This story seeks to shed some light on the concept of coupled oscillators by explaining the two models of coupling and explore the nuances of each system. Before exploring resonance, the reader is encouraged to review the basics of sprung oscillators and isochronism in order to become more familiar with the hairspring and balance wheel model.  The F.P. Journe Chronomètre à Résonance Souscription No. 2 sold for more than CHF3 million in November 2025. A confusion of terms First, the term resonance itself requires definition. In classical physics (mechanics, electrical engineering, signal processing, etc.) resonance is a phenomenon where a system vibrates under the influence of an external driving force that matches the system’s eigenfrequency (natural frequency). This is to say that a system at rest, which includes mass and spring elements, can be excited into a state of resonance by an external force when particular conditions are met. An imp...

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...
