A Legacy of Excellence

Founded in 1967 by the renowned master skeletonizer Armin Strom, this Biel-based independent watchmaker has built a legacy around making movements the focal point of their designs. With a leadership transition in 2009 to Serge Michel and Claude Greisler, Armin Strom evolved into a true manufacture, creating in-house calibres like the distinctive Equal Force barrel featured in their System 78 line.

Introducing the Gravity Equal Force Ultimate Sapphire Blue

The latest addition, the Gravity Equal Force Ultimate Sapphire Blue, showcases a breathtaking twist on the open-dial concept. Housed in a sleek 41 mm stainless steel case, its transparent sapphire dial reveals three elegantly designed finger bridges and the intricate gear train beneath, offering a glimpse into its mechanical heart. Measuring 12.65 mm in height and with a lug-to-lug length of 48.09 mm, this beauty is also water-resistant up to 3 ATM.

Artistry and Functionality Combined

Every aspect of this watch is meticulously crafted in Biel. The mainplate features a stunning PVD coating in glacial blue, adorned with exquisite guilloché engraving by the esteemed independent watchmaker Kari Voutilainen. The rhodium-plated hands are not just a design flourish; they are filled with Super-LumiNova to ensure readability in any lighting. Completing the look is a blue nubuck leather strap with ice-blue stitching, secured by a stainless steel folding clasp.

Innovative Engine Under the Hood

At its core, the watch boasts the in-house automatic calibre ASB19. This sophisticated micro-rotor winds a patented Equal Force barrel, utilizing stop-work declutching to maintain a consistent torque from the mainspring to the movement, ensuring reliability throughout its impressive 72-hour power reserve. Running at a precision rate of 25,200 vibrations per hour, this 202-part, 28-jewel movement is assembled twice—first for mechanical accuracy and then for aesthetic perfection.

Limited Availability and Exclusive Pricing

Only 25 pieces of the Ultimate Sapphire Blue will be produced each year, making it a remarkable addition to any collection. Priced at CHF 27,500 (approximately $34,413), this exquisite timepiece is now available from Armin Strom and authorized retailers. Don’t miss the chance to own a slice of horological art!
