Portrait – David Candaux, An Independent Watchmaker with the Soul of the Vallée de Joux

Independent watchmaking has been on the rise over the past 20 years, and for good reason. Independent watchmakers are guided by passion and personal perspectives, leading to authentic creations and often crafted to a level unattainable in mass production. David Candaux’s motto, “Le Coeur et l’Esprit” (the heart and mind), perfectly captures this philosophy. Raised […]

The Seiko 7559-5010: Admiring the Brand’s First Backlit Analog Movement in its Most Unique Form

In this hobby of ours, there constantly exists the urge to dive down new rabbit holes and subgenres of watch collecting, awaiting the next reason for us to open our wallets and find a reason to justify purchasing another piece. While this typically takes the form of a unique color combination or bezel insert, what about a function like backlights? Sure, Timex’s Indiglo has most certainly found mainstay within the watch industry––as has Casio’s Electro Luminesce technology and of course lume––but what others are out there? For those who haven’t had the pleasure, I now have the honor of introducing you to the fairly forgotten Seiko 7559 movement, utilized here in its most unique application: the 5010 model.  A Brief History of the Cal. 7559 and its Applications As is the story with most watches I tend to develop an interest in, little is known about the design process behind this movement or model outside of repair manuals, blog posts, and owner photographs. The information included here is based on my own research, and I invite anyone interested in this model or movement to include any additional material they may know in the comments section below. Though I’ve attempted to collect as much information on the subject as possible, I would be delighted to hear that more pictures or materials of any kind exist elsewhere.  Production of the cal. 7559 began somewhere in the summer months of 1978 and continued until the late 1980s. The quartz movement itself is a...

Louis Erard and the Horophile Team Up Again for Collaboration #2 Worn & Wound

Louis Erard and the Horophile Team Up Again for Collaboration #2

It should come as no surprise to regular readers of Worn & Wound that we are big fans of Louis Erard. Their irreverent and original approach to watchmaking sets them apart in a crowded market and rarely fails to bring a smile (sometimes literally). But for as good as the brand can be on their own, they are at their best when they aren’t going alone.  Collaboration has been the name of the game for Louis Erard in recent years, and this year’s Louis Erard x The Horophile La Petite Seconde Metropolis is an excellent reminder of why. First introduced around this time last year, the first collaboration between Louis Erard and The Horophile (aka Amr Sindi) was a masterclass in updated Art Deco design, and offered collectors a wonderfully understated and modern dress watch. This latest iteration of La Petite Seconde Metropolis builds on last year’s releases, reimagining the detailed watch with a vibrant green dial. If last year’s trio of Metropoli was Louis Erard reflecting back on 1920’s New York, they would tell you that this year’s release is a more contemporary take on the concept. Nowhere is this more evident than in Louis Erard’s use of color. Where last year’s trio of salmon, slate, and tobacco dials punctuated by rose gold accents were unapologetically old school, the green and silver colorway feels decidedly more modern. Of course, look to the remaining Art Deco icons of New York or Paris, and you’ll see plenty of green - from the stained glass windo...

Is There A Future For The Brick-And-Mortar Multi-Brand Watch Dealer?

It’s no secret that the number of authorized multi-brand dealers for big watch companies has decreased significantly in the last decade. Only the large(r) chains, such as Wempe, Bucherer, Watches of Switzerland, and some local ones, seem to keep their portfolios secure with the big groups and brands. The traditional “mom-and-pop” jewelers are vanishing from […] Visit Is There A Future For The Brick-And-Mortar Multi-Brand Watch Dealer? to read the full article.

Urwerk’s Legendary EMC is Back in a Limited Edition Inspired by the SR-71 Blackbird

Ahead of Geneva Watch Days next week, Urwerk has unveiled what will surely be in the running for “Watch of the Year” talk when 2024 comes to a close. The EMC SR-71 is a new variation of one of the independent brand’s most discussed and honored timepieces. The original EMC, introduced ten years ago, is a former winner of the GPHG prizes in both the “Mechanical Exception” and “Innovation” categories. Even within the strange world of Urwerk, the EMC is an oddity, so it’s always exciting to see them return to this platform with a new variant.  EMC stands for Electronic Mechanical Control, a term that seems to contradict itself but actually does a fantastic job of describing exactly what this watch does. What you need to know about how this watch operates is that the traditional time telling functions (hours, minutes, seconds, and power reserve) all operate mechanically. But integrated into the movement is an optical sensor linked to the balance that, on demand, can record the rate at which it is oscillating. Using light and an integrated circuit, the movement will tell you the delta between the timing rate of the mechanical movement and a reference oscillator (a 16,000,000 Hz mega-quartz oscillator in this case). Pressing a button on the side of the case activates a meter at roughly 10:00, telling you how fast or slow your watch is running. What’s more, the watch is equipped with a timing adjustment screw on the caseback that can be accessed by the owner wit...
