About Kazuo Hirai’s watch collection
Kazuo Hirai is one of the most recognizable executives in the history of the consumer electronics industry. Born in Tokyo in 1960, he spent the bulk of his career at Sony Corporation, rising through the ranks from a sales and marketing role in the company's music division to eventually becoming President and CEO of the entire corporation in 2012. During his tenure at the top, Hirai oversaw a significant restructuring of Sony, steering the business away from loss-making hardware segments and refocusing it around entertainment, imaging sensors, and gaming — most visibly through the continued growth of the PlayStation platform. He stepped down as CEO in 2018 and relinquished his role as Chairman in 2019, leaving behind a legacy as the executive who helped stabilize one of Japan's most storied technology companies during a particularly turbulent period.
The Kazuo Hirai watch collection, as far as public sightings allow us to document, points toward a preference for well-regarded, broadly respected watchmaking rather than anything ostentatious. He has been spotted wearing a Rolex Cosmograph Daytona reference 116523, the two-tone variant that combines an Oystersteel case with 18k yellow gold bezel, crown guards, and matching Oyster bracelet with a yellow gold Oysterlock clasp. The ref. 116523 occupies the middle ground in the Daytona lineup — not the full steel 116520, not the solid gold 116528 — and is powered by Rolex's calibre 4130, the brand's in-house automatic chronograph movement introduced in 2000 and widely regarded as a robust and accurate piece of engineering.
The choice of a two-tone Daytona says something concrete about Hirai's approach. The reference 116523 is a recognizable watch to anyone with a passing interest in Rolex, but it stops well short of being a flashy choice. For a former chief executive who managed a company with revenues exceeding 75 billion USD, it reflects a measured sensibility — a watch that signals awareness of craft without going out of its way to draw attention.
