This timepiece is in unworn condition. It comes as a complete set including both inner and outer boxes and warranty card. Warranty activated January 31, 2026 — valid through January 31, 2031. MSRP: 79,630 USD. Limited to just 27 pieces worldwide.
The watch that marked the full rebirth of an icon, the Hastroid "Green Nebula" is a 48mm timepiece in black-coated titanium and carbon composite measuring 17.2mm in thickness — the opening statement of an entirely new chapter following the brand's resurrection under new ownership in 2022. At its heart is the proprietary Meca-Fluidic Technology: a retrograde fluid display in which a luminous green liquid flows through a capillary tube arcing around the dial to indicate the hours, driven by micro-pistons and bellows visible through the case architecture. Once the fluid reaches the end of its arc at 6 o'clock, it retrograde-returns instantly to restart the cycle. A central minute hand, small seconds at 9 o'clock, and a power reserve indicator at 3 o'clock complete the display beneath a domed sapphire crystal. Presented on a rubber and embossed Alcantara strap. Retailing at 79,630 USD, this example is offered below current retail. The hand-wound 501-CM comprises 41 jewels, beating at 28,800 vph (4 Hz), and delivering approximately 72 hours of power reserve, water-resistant to 50 meters.
