Laurent Ferrier: A Conversation on the Brand That Set the Mold for Modern Independent Watchmaking

Two Laurent Ferrier fans, CS members Andrew Kandel and Mike Allen, discuss why they love the brand, what it feels like to wear one on the wrist, and its legacy as the original indie watch brand.

The Bvlgari Octo Finissimo: Geometry and Genius

Every 20 years or so, a watch comes along that changes everything. Aficionados have described the Bvlgari Octo Finissimo as a triumph of modern design, a milestone in the world of icons and a pleasure to wear. Some even say it breathes the same rarefied air as the Royal Oak and the Nautilus. How did the Octo Finissimo capture the imaginations of so many collectors, and what is next for the holder of 10 world records? Can its trajectory be sustained?

200 Years in the Making, 40 Years in the Perfecting – Bernhard Lederer’s CIC Movement And Its Importance To Horology

Collector Dan Adelman contemplates the history of the constant-force natural escapement, and explains why Bernhard Lederer’s CIC is the “natural” successor to inventions by A.L. Breguet and George Daniels. Like collectors before him, the Lederer escapement makes him think more deeply about the beauty of timekeeping.

L.Leroy: The Right Time For A Relaunch

When L.Leroy reappeared on the watch scene in 2025, it was a reflection of a heritage dating back to the 1700s. L.Leroy was on the scene to contribute to the original development of watchmaking’s foundational principles. That history, along with a solid plan for the future, is present in its current collections.

Beneath The Rock – The Royal Navy, Gibraltar & The Rolex MilSub

The strange story of a rocky outcrop, penguins, the military and watches. MilSubs are few in number, the same watches are often seen at auctions exchaging hands frequently, over and over. Rarely does one of the 1,250 known examples emerge from a sock drawer for the first time in 50 years, and stranger still is the story of how and why.

Zenith Calibre 135 G.F.J. – A Masterclass in Heritage, Precision and Revival

Few mechanical movements embody the golden age of precision like Zenith’s Calibre 135. First developed in the late 1940s, it dominated observatory trials and became the most awarded chronometer calibre ever created. Today, Zenith revives this legacy with the G.F.J., a reimagined collection that blends archival precision with modern craftsmanship. It is a continuation, not an imitation, and a reminder that true innovation comes from understanding what once worked perfectly and daring to let it live again.
