With a unique guilloché pattern on the vibrant, sapphire blue base plate, the latest edition of the Gravity Equal Force introduces a striking combination exclusively crafted for Oster Jewelers in a series of only 10 pieces. The base plate features a vintage-inspired Tapestry pattern guilloché, expertly engraved in the atelier of renowned independent watchmaker Kari Voutilainen using a traditional rose engine lathe. This striking and regal blue hue is applied through an advanced 3D PVD process, allowing it to display a mesmerizing spectrum of tones as it catches the light.
Enhancing its uniqueness, the small off-centered dial is crafted from transparent sapphire crystal, a feature reserved exclusively for the Gravity Equal Force’s Ultimate Sapphire Editions. Completing this masterpiece is a light grey nubuck leather strap, accented with contrasting white stitching, adding a touch of sophistication.
The Gravity Equal Force Ultimate Sapphire OSTER is a true limited edition, with only 10 pieces produced. This timepiece is a testament to Armin Strom's dedication to innovation, artistry, and unparalleled craftsmanship and the creative partnership with Oster Jewelers.

The Gravity Equal Force stands out as the pioneering automatic watch with an equal force transmission mechanism directly integrated into the mainspring barrel—a patented innovation by Armin Strom. This advanced system ensures consistent power delivery to the regulating organ, maintaining precise timekeeping throughout the watch’s power reserve. The power reserve indicator is integrated within the barrel, fully visible from the dial side, opposite the micro-rotor, which boasts a unique click system with dual springs for enhanced winding efficiency.
This latest creation, born from Armin Strom’s relentless pursuit of superior chronometric performance, was meticulously developed, manufactured, and decorated entirely within the state-of-the-art facilities in Bienne. Reflecting the brand’s commitment to perfection, the Gravity Equal Force Ultimate Sapphire Oster Blue's movement undergoes a rigorous assembly process. Initially assembled to confirm flawless operation and adherence to stringent decorative standards, it is then carefully disassembled and reassembled before being cased in its final, exquisite form. This meticulous process underscores Armin Strom's dedication to creating horological masterpieces of unmatched precision and beauty. Completing this masterpiece is a light grey nubuck leather strap, accented with white stitching and keepers, adding a touch of sophistication.
