Bespoke Watches
Cosmic Quartet features four meticulously crafted Reserve Edition watches, each bearing a distinct dial and case combinations reflective of our earth, our moon and more remote celestial elements.
Inspired by over 5,000 years of Irish horological heritage, the foursome pays homage to our own planet, and celestial bodies that have guided humanity's understanding of time and other heavenly bodies that continue to intrigue modern day astronomers.
