A legendary icon of space exploration, recreated with VSF’s precision engineering—featuring the authentic manual-wind Cal.1863 clone and the signature sapphire crystal front and back design that earned it the “Sapphire Sandwich” nickname.

Powered by VSF Custom A1863 (Super Clone)

At the heart of this historic timepiece lies VSF’s masterfully recreated A1863 manual-winding chronograph movement, engineered to mirror the genuine Omega Cal.1863 down to the smallest detail.

Unlike inferior replicas with unstable chronograph functions, VSF’s A1863 delivers precise timekeeping, crisp chronograph engagement, and the satisfying tactile feedback of manual winding that purists demand.

Technical Specifications

THE BUILD

316L Stainless Steel Icon

VSF has replicated the legendary 42mm Speedmaster case with exacting precision, capturing the original’s robust yet elegant profileOMEGA®. The lugs feature the correct brushing pattern, while the chronograph pushers offer the iconic “click” feel that has been tested in space. The integrated steel bracelet includes solid end links and the historic Omega folding clasp, providing a secure fit and authentic weight that pays homage to the watch worn on the moon.

THE FACE

Black Dial with Vintage Appeal

The matte black dial features the classic three-subdial layout (30min at 3, 12hr at 6, small seconds at 9) with applied hour markers and luminous baton hands that glow with Super-LumiNova clarity. VSF has meticulously reproduced the font on the subdial scales and tachymeter bezel to match the genuine 3573.50.00, right down to the Omega logo placement and vintage “Professional” text.

THE BEZEL

Black Aluminum Tachymeter

The iconic black aluminum bezel with engraved tachymeter scale is recreated with perfect color accuracy and depth. VSF uses high-grade aluminum that won’t fade or scratch easily, with crisp engravings that provide the same readability as the original moonwatch. The bezel action offers the precise 120-click rotation that professional pilots and astronauts relied on.

REFINEMENT

Dual Sapphire Crystal Design

What makes this reference truly special is its “Sapphire Sandwich” construction—VSF has fitted both front and back with scratch-resistant sapphire crystal with anti-reflective coating. The exhibition caseback reveals the beautifully decorated A1863 movement, allowing you to admire the oscillating rotor and intricate gear train while paying tribute to the watch’s space heritageOMEGA®.
