Interview - Andreas Wyss, CEO of the COSC, on the Need to Adapt and a “Super-COSC” Certification to Come

If you own mechanical Swiss watches, one of them potentially came to you with a COSC chronometer certificate. But not everyone knows exactly what this certificate means. The COSC is the Contrôle Officiel Suisse des Chronomètres or the Official Swiss Chronometer Testing Institute. COSC certifies Swiss-made movements or watches as chronometers (not to be confused […]

Formex Introduces the Essence Ceramica Skeleton COSC, Featuring a Full Ceramic Bracelet (with Micro-Adjust!)

We talk a lot about Formex here, and for good reason. Now celebrating its 25th year, Formex has built a well-earned reputation for pushing the limits of what we can expect from small, technical brands, and they’ve done it all while cultivating a pretty dedicated audience. Head to a Windup Watch Fair anywhere in the country and you’re sure to find a thick mass of enthusiasts trying to squeeze their way up to the Formex table in the hopes of checking out whatever wild watch the brand has most recently introduced. Formex’s latest and greatest is a new take on their fan-favorite Essence, only this time, it’s ceramic. The Essence Ceramica Skeleton COSC is a serious statement of technical capacity for a brand that has, up until now, never produced a fully ceramic watch (or, at least to my knowledge, a skeletonized one). With the Essence Ceramica Skeleton COSC, they’ve managed to do it while not only maintaining all the complexities of the Essence case - like the suspended mid-case the brand is known for - but also while introducing what they purport to be the world’s first micro-adjustable ceramic bracelet. On some level, it’s not remotely surprising that, with their first-ever ceramic watch, Formex would look to blow the competition out of the water, or that, in that attempt, they would largely succeed. I’ve yet to see these new watches in person (hopefully soon), but at first glance, these seem to be finished to a level far beyond what we normally see from ...

Elegance Meets Accuracy - Going Forward, All Of Serica’s Watches Will Be COSC-Certified Chronometers

Any young watch brand constantly has to make choices about designs, costs, quality, and many other aspects that affect the organization every day. In the case of Serica, a young Parisian brand founded in 2019, elegance, reliability, and accuracy steer the decision-making process. In terms of elegance, I don’t think there was anyone who thought […] Visit Elegance Meets Accuracy - Going Forward, All Of Serica’s Watches Will Be COSC-Certified Chronometers to read the full article.

Serica Bolsters the 5303 COSC Antimagnetic Diving Chronometer from Within

Although Serica has only been around since 2019, it feels like the young watch brand has been around for ages. In my opinion, a lot of that has to do with the maturity in which they conduct themselves, both in brand presence and progression. With any Serica novelty, you can bet that their approach to any watch design is performed with metronomic consistency – typically with minimal branding, steady visual cues, and a general inspiration by way of vintage military timepieces. It seems that any change that’s going to be made within each reference will be incremental, but that doesn’t mean the impact can be monumental. Such is the case with the new and improved Serica 5303 COSC Antimagnetic Diver Chronometer. To understand the latest update to the Serica 5303, we must look within. Serica has opted to keep the movement within the Soprod family, but instead of using the previous Newton P092 automatic, the Serica 5303 COSC now draws its power from the Caliber M100. The Soprod Caliber M100 is buoyed by a glucydur balance, incabloc shock system, a 42 hour power reserve, and most importantly, a 3.2mm movement thickness. With approximately 1.4mm of extra room to play using the transitional movement inside of the 5303 COSC case, Serica has built in several antimagnetic pieces including a soft iron movement holder, soft iron dial and a soft iron inner caseback. As a result, the magnetic resistance for the Serica 5303 COSC diver has skyrocketed from the traditional Swiss standard...
