From Audemars Piguet’s secret technologies to Breguet’s monumental celebrations, from Richard Mille’s dizzying transparencies to H. Moser & Cie’s futuristic experiences, to the rediscovery of a forgotten Patek Philippe prototype… Each maison reveals a facet of its genius, between centuries-old traditions and innovations that redefine time.

The RD# Tradition

The saga of Audemars Piguet’s “RD#” series, launched in 2015, illustrates the balance between watchmaking tradition and technical innovation. Each model — from RD#1 to RD#5 — represents a quest for perfection, pushing boundaries: RD#1 revolutionized minute repeaters with “Supersonnerie” technology; RD#2 set a record for thinness with the world’s flattest self-winding perpetual calendar; RD#3 introduced an extra-thin automatic tourbillon in a “Jumbo” case; RD#4 brings together all major complications in a self-winding wristwatch with over 40 functions; and RD#5 combines chronograph, tourbillon, and modern ergonomics to redefine the daily utility of haute horlogerie.

A Black Hole on the Wrist

The Streamliner Genesis 2 by H. Moser & Cie represents the second chapter of an experimental triptych. It retains the cushion-shaped case and integrated bracelet of its predecessor while introducing a Vantablack dial that absorbs light to create a striking visual effect. The pixelated hands with Globolight inserts provide legibility and modernity, while the in-house automatic HMC 203 caliber, visible through the sapphire caseback, delivers a 72-hour power reserve. Produced in a limited edition, this watch combines technical innovation, bold aesthetics, and continuity with the first model of the trilogy, designed for collectors.

Flying High Again

A prototype watch — nickel-plated, large, designed as an aviator’s watch, equipped with a disengageable central seconds hand — resurfaces under the spotlight: the rare Patek Philippe ref. 81227. Produced in the 1930s–1940s, it stands as a historical testament to the manufacture’s expertise in aviation timekeeping — a field rarely discussed today. Long forgotten, this 81227 sparks renewed interest in 2025, reminding us that Patek has never ceased to explore diverse applications, blending technical innovation with traditional craftsmanship.
