INTRODUCING: The Audemars Piguet Ladies’ Royal Oak turns 40 in style

OK, we’re calling it: 1976 was one of the best years in history – for so many reasons. For a start, that’s when Stevie Wonder’s Songs in the Key of Life was released. It was also the year Rocky and Taxi Driver hit cinemas, and superhotties Benedict Cumberbatch and Audrey Tatou entered the world.

[su_vimeo url=”https://vimeo.com/189240316″] It’s 2016, so why would anyone wear a pocket watch? That’s the question I found myself asking this week as I took the Tissot Bridgeport Lepine for a test drive. And look, I’m not going to lie to you, it took more thought to integrate this 45mm little number into my life.

INTRODUCING: The dark elegance of the Cartier Santos 100 Carbon

You’d be forgiven for thinking that Cartier’s only men’s release of 2016 was the Drive de Cartier. But in addition to this handsome new collection Cartier decided to revive one of the dark horses of their collection – the Santos 100 Carbon. Until 2012, if the regular metal versions of the Santos weren’t your thing, … ContinuedThe post INTRODUCING: The dark elegance of the Cartier Santos 100 Carbon appeared first on Time+Tide Watches.

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 […]

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...

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. ...

The Ulysse Nardin Freak – The Saga of a Scientific Timepiece Part III SJX Watches
Patek Philippe Mar 31, 2024

The Ulysse Nardin Freak – The Saga of a Scientific Timepiece Part III

An outlandish concept that originally sprang from the mind of Carole Forestier Kasapi, the Ulysse Nardin Freak of 2001 was perfected by Dr Ludwig Oechslin and then made reality thanks to the advent of silicon in watchmaking. Lightweight and magnetism resistant, silicon was used for the escape wheels but that was only the beginning of the story. [This story, the third and final instalment in the series, details the history of silicium, the proprietary Ulysse Nardin silicium hairspring, and the patented Grinder rotor. The Saga of a Scientific Timepiece Part I covers the origins of the Freak, from its conception to realisation, as well as its distinguishing characteristics, namely the inventive movement construction and unique escapement. Part II deals with the evolution of the unique, high-performance escapement.] Silicon, Silicium, Silinvar Now used interchangeably with silicon, silicium is actually French for “silicon”, but now it is also used as the trade name for the proprietary form of silicon used by Ulysse Nardin for movement components, namely silicon with a hard oxide outer layer that gives the material thermocompensating properties. Silicium was developed by Swiss scientific institute Centre Suisse d’Electronique et de Microtechnique (CSEM) in collaboration with Ulysse Nardin. Notably, the material is also known as Silinvar, which resulted from a separated but related CSEM project backed by a consortium made up of Rolex, Patek Philippe and Swatch Group. As a ...
