Burgess Clock B is the World’s Most Precise Pendulum Clock and is Made to a 250-Year-Old Design by John Harrison, Longitude Prize Winner and Inventor of the Marine Chronometer

Two-hundred fifty years ago, Longitude Prize-winning clockmaker John Harrison made clocks losing just one second per month. But that wasn't enough for him: in his later life, Harrison claimed that he could make a wall clock with a then-unheard-of-precision of just one second over 100 days! And 250 years later, it turns out he was right.

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...

Brellum Throws Their Hat into the GMT Ring with the Pilot LE.1 GMT Chronometer

Brellum is an up and coming independent brand that prides itself on its rich familial history in watchmaking. Founder Sebastian Muller can trace his family lineage of watchmakers all the way back to his great grandfather who set up his very own shop in 1910. The rest, as they say, is history. Brellum exists today with the intention of continuing the Mueller legacy by producing highly-crafted timepieces that, not only present with a thoughtful design for the modern day wearer, but to pay homage to their family’s passion for traditional Swiss watchmaking. Their surname is an anagram in the brand’s namesake afterall. Recently, the brand announced a very limited run of a handsome pilot’s chronograph equipped with a GMT function with the Brellum Pilot LE.1 GMT Chronometer. The dial is where the Brellum Pilot LE.1 GMT Chronometer shows a whole lot of flash without straying too far away from the traditional pilot’s watch aesthetic. And by flash, I mean that opalin silver-now dial. From the images, it seems that this dial has its own character all on its own, displaying a luster against radiant lighting, and then a more toned down matted white in neutral lighting. All of the dial markings use black as the main color for unmistakable legibility including the minute track, 24 hour display bordering the outer portion of the dial, and applied numeral hour markers. The subdials take up dial real-estate at six, twelve and nine with a date window sneaking into the six o’clock s...
