Armin Strom, the Swiss luxury watch manufacturer known for its edgy, eye-catching skeletonized mechanics, has just launched a rare and stunning new version of its milestone Gravity Equal Force timepiece. With its off-center grey-toned sapphire dial, the strikingly cool monochrome watch offers an extraordinary view of the exquisitely-finished manufacture movement and further enhances the brand’s reputation for its irrepressible, exuberant independence. Armin Strom’s Gravity Equal Force is the world’s first automatic watch with constant force transmission, which results in consistent power delivery to the balance. In short, it means that the watch always delivers flawlessly constant precision with its in-house ASB19 calibre that offers a power reserve of 72 hours.
The timepiece stands out not only with its groundbreaking technology but by a design and craftsmanship that set it apart from every other watch. With the launch of the Gravity Equal Force Ultimate Sapphire, Armin Strom has reinforced its commitment to providing full view of the mechanics that have been generating an industry-wide buzz since the brand’s beginnings. The watch is distinguished in equal part by its technical and aesthetic innovations.
The movement’s black plate guilloche pattern was created by hand by the celebrated Finnish watchmaker Kari Voutilainen, a close friend of Armin Strom’s founders. The bridges are coated with dark grey ruthenium; the barrel and the micro-rotor are coated with rhodium. The Gravity Equal Force’s ASB19 movement includes a “stop work” mechanism that prevents the mainspring from fully unwinding, thus leveraging only the part of the mainspring’s unwinding process that can deliver power most consistently.
The steel hands with super-luminova are manufactured by Armin Strom and like all of the visible parts of the movement, are meticulously hand-finished in-house. Presented in a classic 41 mm stainless-steel case, the Armin Strom Gravity Equal Force Ultimate Sapphire comes with a black fabric strap with light grey stitching, subtly maintaining the watch’s resolutely cool monochrome color scheme.
Claude Greisler, Armin Strom’s co-founder and head watchmaker, points out that the new watch’s cool, understated monochrome design will appeal to fans of the brand’s design philosophy: “We’ve re-imagined the Gravity Equal Force to more fully embrace our passion for transparent mechanics, while adding complementary aesthetic complexity that enhances the watch’s special visual impact.”
Serge Michel, founder of Armin Strom adds: “The special version of our Gravity Equal Force was extremely well received in early presentations to collectors so we hope to be able to produce 30 more watches next year in addition to the 15 from this year. That may, however, be too ambitious because our capacities are limited and it always has to be a rare piece, which is why we have decided that half of all future productions will be placed on a first-come/first-served waiting list for those who inquire via our website.”
This breathtaking new Gravity Equal Force timepiece was designed and produced in-house at the brand’s manufacture in Biel. Like every Armin Strom watch, its movement has been assembled twice. After its first assembly, the movement was painstakingly disassembled and each individual part was cleaned, dried, reassembled and lubricated before being meticulously regulated, tested, and returned to the case.
Launched in 2019, the milestone timepiece demonstrates Armin Strom’s core principle: to bring innovation to every watch. It combines the brand’s celebrated passion for transparent mechanics and its distinctive design as well as its commitment to redefining the horological landscape with every new product.
The Gravity Equal Force Ultimate Sapphire will be available from October 2021 in a limited quantity of 15 pieces for 2021. Due to the limited production capacity, the special timepiece will be available subsequently in a very small number of pieces per year.
