Singer Reimagined Minds its Manners with the Caballero SJX Watches

Singer Reimagined Minds its Manners with the Caballero

Best known for its Agenhor-powered chronographs, Singer Reimagined has just released its first time-only watch, the Caballero. Inside is the Calibre-4 Solotempo representing another first, being the brand’s first proprietary movement. With four barrels powering the Caballero for six days, the Calibre-4’s distinctive architecture can be discerned from the front thanks to jewel portholes in the dial. Spanish for “gentleman”, the Caballero is available in three colourways; the piano black and empire green colours are familiar from the Heritage Collection chronographs, but the petrol blue colour is new for the brand. Though not strictly a limited edition, the watches will be rare enough, assembled in small quantities at the brand’s atelier in central Geneva. Initial thoughts There tends to be a lot of crossover between the worlds of horology and high-end cars. Fans of the latter are no-doubt familiar with Singer Vehicle Design, which has made a name for itself restoring and modifying vintage Porsche 911s – specifically the 964 of the early 1990s – elevating the model to a standard that would have been impractical in its own time. The watchmaking arm, which operates as an independent sister company, has been quietly making interesting watches since 2017, largely focused on vintage motorsport themes. For the Caballero, this inspiration is conveyed most prominently by the golden needle hub that covers up the base of the hand stack, similar to those used by vintage a...

The Power of Community: Expanding My Watch Family at the Brew Summer Popup

Whether you’re a collector or working in the watch industry, the experience is never just about the watches themselves – it’s about the people you meet along the way and finding a sense of community. Not to sound dramatic, but when you do, it changes everything. There are so many subsets of the watch world, and discovering the people that align with you to nerd out, swap stories, and take wrist shots is what makes this hobby and this work fulfilling and, above all, fun.  First off, let’s get a little personal: a lot of people both within the industry and the community may not know I’ve been working in the watch sphere for 13 years. In that time, I’ve experienced firsthand that exclusivity is an inherent and at times more problematic part of horology and that there can be barriers to feeling a part of this incredible watch world, particularly as a woman.  For me, getting here – having opportunities for my voice to be heard on influential platforms like Worn & Wound that are vital to this industry and collector community – has been a slow burn. It took time for me to carve out my place in watches as a woman, as a millennial, and as a freelancer.  Early on, there were a few people who became the foundation of my watch community – people who didn’t care to measure my value by the number of outlets where you could find my byline or the number of watches in my personal collection. They saw my genuine curiosity and infatuation with timepieces and my abiliti...

First Look – Three New Models in the Hamilton Khaki Pilot Pioneer Collection

Hamilton’s latest models from the Khaki Pilot Pioneer collection have been updated with new bezels, dials and strap colours to bring a “civilian” touch to the more conservative, military-inspired watches. The collection is (loosely) based on the World War II Model 23 pocket watch for U.S. Air Force navigators and splinters off into modern 43mm […]

Berneron Jumps Forward with the Quantième Annuel SJX Watches

Berneron Jumps Forward with the Quantième Annuel

One of the headline releases from Geneva Watch Days is, without question, the Berneron Quantième Annuel, a symmetrical annual calendar that brings the brand’s vision into sharper focus. Expensively made and cleverly designed inside and out, the Quantième Annuel is a showcase for founder Sylvain Berneron’s attention to detail. A limited run of 480 pieces in platinum, with production spaced evenly over the next decade, the Quantième Annuel is available in two dial configurations; whether the buyer opts for lacquered silver or piano black, the dial itself, along with much of the movement, is crafted from 18k gold. Initial thoughts I’ve written effusively about user-friendly complications in the past so it should come as no surprise that I like the Quantième Annuel’s legible display and intuitive interface. Visually, it’s a world apart from the oozy Mirage, but it exhibits a similar degree of intellectual sophistication and attention to detail. A jumping hour watch with an instantaneous annual calendar, the Quantième Annuel is distinguished by its oversized windows for the hour, day, and month, with a sector-style dial for the minutes and a concentric retrograde date display. The running seconds dial at six o’clock contains the fourth jumping window for the day/night indicator; a useful addition for any calendar watch. The watch is designed for easy legibility, with the time read top-to-bottom and the date read left-to-right. The sector dial for the minute han...

Introducing: The Bianchet UltraFino Sapphire - A Transparent Take On The Ultra-Thin Tourbillon

Sapphire-cased watches have crept up on me lately. I used to think of them as fragile showpieces, destined for safes rather than wrists, but something has shifted. It probably started with the ArtyA Luminity Wavy collection, which made me stop and think about how sapphire can do more than just look flashy. Now, with Bianchet’s […] Visit Introducing: The Bianchet UltraFino Sapphire - A Transparent Take On The Ultra-Thin Tourbillon to read the full article.

Watches, Stories, and Gear: The Jot N Pop, Stirling Timepiece’s Jarvis GMT, and The Return of Iconic Designs From Tom Bihn and Giant Mouse

“Watches, Stories, and Gear” is a roundup of our favorite content, watch or otherwise, from around the internet. Here, we support other creators, explore interesting content that inspires us, and put a spotlight on causes we believe in. Oh, and any gear we happen to be digging on this week. We love gear. This week’s Watches, Stories and Gear is sponsored by Stirling Timepieces. Check out the new Jarvis Diver GMT and a link to their website below. Notorious EDC and Big Idea Design Create the Jot N Pop Photo courtesy of Dave Svarte These days, collaboration is the name of the game. Whether it’s teaming up with a famous soda brand (looking at you Seiko and Jack Mason), or two EDC powerhouse brands creating something entirely different. When our team was at Blade Show this year, we got a sneak peak of the first Jot N Pop prototype and knew it was going to be something special.  According to Tom Medovich, “The Jot N’ Pop is what happens when you mash up Big Idea Design’s Pocket Pro with the Beer Bomb. A titanium pen that’s built to do whatever you throw at it, as long as whatever you throw at it is writing stuff down or opening bottles.”  Regardless of how they came up with this idea, we can’t think of a more perfect tool for staying hydrated and taking notes! Built upon the design of the Pocket Pro, the new Jot N Pop is entirely machined from Grade 5 titanium (no plastic parts!), with a pocket clip made from grade 4 Ti for spring tension. Arguably the mos...
