British Watchmakers' Day 2025 Special Edition.

Gordon Bennett, our special edition timepiece for British Watchmakers' Day 2025, features a lustrous British Racing Green dial.

British Racing Green holds a unique place in the annals of motorsport history, with its roots in the 1903 Gordon Bennett Cup, a landmark event held on Irish soil. This came about because in the early 1900's public road racing was prohibited in England. In a gesture of respect to its Irish hosts, Britain's Napier team chose a rich shamrock green for their racing cars, forgaing an Irish connection to this much loved, archetypal British colour.

This special edition piece is limited to just five examples. The deep lustrous dial captures the timeless elegance of British Racing Green, and evokes a modern aesthetic that's both distinctive and understated. Available to pre-order from 10.00am on Saturday the 8th March 2025.

"We've designed this special edition to celebrate the historical link between Britain and Ireland and the legacy of this much-loved hue that continues to find favour with both automotive and horological enthusiasts. This historical link mirrors the spirit of collaboration and shared tradition that unites members of the Alliance from across the British Isles." Bryan Leech, Co-founder of Sidereus Watches.

British Watchmakers' Day 2024 Reserve Edition.

Cosmic Quartet featured 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.
