USA Issue 65
Revolution Fall 2022
In our cover story this issue, we discover Longines’ historical milestones in their use of high frequency timepieces and devices for measuring some of the most important and exciting sporting events, leading up to the current 5Hz caliber in their Ultra-Chron timepiece.
Elsewhere in this issue, Revolution founder Wei Koh shines the spotlight on the Audemars Piguet Royal Oak and its stunning impact on the luxury watch market, while editor-at-large Cheryl Chia looks back at the incredible achievements of Daniel Roth.
And especially for the watch geeks, we put forward technical stories on the concept of equation of time, secular perpetual calendar complication, the high-speed mechanism of Patek Philippe 5470P, and the rare feat achieved by the Grand Seiko caliber 9SA5.
