Blue Sapphire. Thickness. Precision.

The Ripples Kármán Line brings together everything that defines Speake Marin at its most technically ambitious: a sapphire crystal dial with blue metallisation, the iconic small seconds at 1:30, and the ultra-thin La City case in 904L stainless steel.

Look closer. The dial is not a surface, it is a statement. Crafted from sapphire crystal glass, its blue metallisation shifts with the light, its reverse side adorned with a sunray finish and Côtes de Genève motif that reveal themselves like a sky seen from altitude. The heart-shaped hour hand moves across rhodium-plated baton indices with quiet authority, while the minute flange, in blue PVD with an opal microbeaded finish, traces the outer limit of the dial like the boundary it is named after: the invisible threshold where Earth's atmosphere gives way to space, 100 kilometres above the surface. Beneath the sapphire crystal, the in-house SMA06 calibre beats at 5Hz, its 175 components held within a movement just 2.5mm thin. The tungsten micro-rotor, decorated with an exclusive pattern of raised and recessed rectangles in alternating rhodium and blue PVD, is as quietly spectacular as the dial it serves. At 6.30mm thick, the 40.30mm La City case barely registers on the wrist. The integrated 904L steel bracelet, with micro-adjustment to the millimetre, completes a watch that leaves nothing unconsidered.

The Ripples Kármán Line. Where watchmaking meets the edge of everything.

Calibre SMA06

Ultra-Thin Mastery, Powered by High-Frequency Precision.

The Speake Marin SMA06 calibre is an in-house automatic mechanical movement developed for the Ripples Kármán Line, where high-frequency precision meets ultra-thinness and refined Swiss finishing. Engineered for both performance and elegance, the SMA06 features a fully integrated micro-rotor, ensuring optimal winding efficiency while preserving a remarkably slim profile of just 2.5 mm in thickness (without hands) within a 32.00 mm diameter. Beating at a high frequency of 5 Hz (36,000 vibrations per hour), the movement delivers exceptional chronometric stability and precision, positioning it among the most advanced calibres in contemporary Swiss watchmaking. Comprising 175 components and 27 jewels, the SMA06 incorporates a variable inertia balance wheel and a Swiss lever escapement, enhancing reliability, durability, and long-term performance. It offers a minimum power reserve of 52 hours, ensuring consistent energy delivery and accuracy. The calibre is distinguished by its meticulous finishing: a rhodium-plated, microbeaded mainplate, paired with bridges adorned with Côtes de Genève, enhanced by hand-executed anglage and polished bevels. At its core, the tungsten micro-rotor reveals an exclusive geometric motif, combining rhodium-plated and blue PVD finishes, bringing depth, contrast, and a contemporary signature to the movement.
