In Focus: Romain Gauthier’s Breathtaking Patented Ruby Link Chain From Logical One – Reprise

Here at Quill & Pad we are quite smitten by Romain Gauthier’s award-winning Logical One. But one thing that often gets glossed over somewhat is the subject of one of this watch’s four patents: the incredible high-precision chain made of synthetic ruby links. Combined with the snail cam, it is this element that provides the ingenious movement with constant force.

Aventurine: Sparkling, Glittering, Mysterious, And Placing A Galaxy Of Stars On Your Wrist – Reprise

Despite seeing aventurine in six new wristwatches at SIHH 2018 – more than the number of new tourbillons Elizabeth counted – it remains a decorative artisanal element used only by luxury watchmakers in small series or unique pieces for its beauty and decorative properties. While there is some public uncertainty about the origin of aventurine, it continues to add mysterious shine and scintillating glamour to watches. Here is what aventurine really is and where it comes from.

TAG Heuer Autavia Isograph: Carbon-Composite High-Tech Hairspring For All

Joshua Munchow thinks that TAG Heuer’s move to separate the Autavia into its own collction and have it be fully supported by Caliber 5 with its Isograph carbon-composite hairspring is a definitive step to creating a new, solid base for the brand to build on.

The Schmidt List: Signature Movement Screws – Reprise

The components of a mechanical watch movement are little more than a series of springs and wheels held together by plates and/or bridges. No matter the configuration, complication or finish, the ensemble is secured by the humble movement screw. So it’s a pleasant surprise that several watchmakers have boldly ventured beyond the thread and the slot to reimagine the movement screw.

The Schmidt List: Top 5 Funky Clicks – Reprise

The click spring is one of the smaller components of a mechanical watch, but it is of enormous importance. Ever wondered why the crown doesn’t retaliate furiously and unwind every time you crank it?

Armin Strom Masterpiece 1: Dual Time Resonance

Understanding Resonance, Featuring The F.P. Journe Chronomètre à Résonance, Armin Strom Mirrored Force Resonance, And Haldimann H2 Flying Resonance (Reprise)

Resonance. No, it is not a Tesla-themed Evanescence cover band. Resonance is a physics principle that, to be honest, most people will never need to know to go about their daily lives. So what is all the hubbub about resonance these days? It’s a word that is, even in the watch world, so mysterious and rare that it is heard only once or twice a decade. In this article Joshua Munchow explains how resonance works and why it matters.
