A tribute to courage, a companion powered by light. The JC01 honours Jerrie Cobb — pioneer aviator, record-breaker, and one of the original Gemini astronaut trainees — with a timepiece that is as forward-looking as her legacy.
Jerrie Cobb’s historic achievements in aviation and spaceflight broke barriers. The JC01 captures that spirit: bold, uncompromised, and visionary in every detail.
No winding, no battery changes. Harnessing sunlight and ambient room light, the Seiko AS01 solar caliber delivers perpetual motion in complete harmony with nature.
Hand-built and regulated in the United Kingdom. Combines a 38 mm stainless steel cushion case, 5 ATM water resistance, and genuine leather with quick-release bars.
Personality through colour: With a vibrant palette of striking colourways, the JC01 isn’t just about telling time — it’s about expressing identity.
An iconic contrast of radiant warm gold and deep matte anthracite. Finished with supple black leather and a quick-release folding clasp.
Crisp mint turquoise ring encircling the deep solar dial. Delivers a vibrant pop of color for both office elegance and weekend leisure.
Pure circular brushed silver dial highlighted by a deep British Racing Green track and fiery red second hand for timeless motorsport heritage.
Deep oceanic midnight blue dial centered within a warm champagne hour ring, handsomely paired with a rich vintage tan genuine leather strap.
Delicate powder pink / candyfloss tone gracefully meeting the high-precision solar cell. Warm, refined, and distinctly eye-catching on the wrist.
Classic champagne sunburst dial accented with cobalt blue hands and an olive green genuine leather strap for authentic retro aviation charisma.
Harnessing the sun’s energy, the JC01 utilizes the Japanese-engineered Seiko AS01 solar movement. Daylight and ambient room illumination pass effortlessly through the dial, converting photons directly into clean electrical energy.
Once fully charged, the high-efficiency capacitor holds an impressive power reserve of approximately four months in complete darkness. No periodic battery changes, no hazardous chemical disposals, and no maintenance hassle. Just perpetual, eco-conscious motion.
Requires regular battery replacements every 1–2 years, creates toxic battery waste, and risks gasket damage.
Perpetual light-powered operation, 4 months reserve, preserves factory seals, and operates in harmony with nature.
