1991 Rolex Datejust "IBM" Ref.16620

Few watches are as universally recognized as the Rolex Datejust. Introduced in 1945, the Datejust set the standard for the modern wristwatch, being the first automatic chronometer with a date function that changed instantaneously at midnight. Its timeless 36mm case, fluted bezel, and signature Rolex dial proportions have made it a pillar in horological design for over half a century.

What makes this particular example exceptional is its provenance and corporate connection. Gifted on December 5, 1991to James V. Nocera Jr., then an executive at IBM, this Datejust represents a unique moment in the storied relationship between Rolex and the corporate world. During the late 20th century, Rolex watches were occasionally presented by global firms like IBM to commemorate milestones and recognize distinguished service—a tradition that not only increased the value of the timepiece, but also underscored its role as a token of achievement.

Adding to its distinctiveness, this example is paired with a stainless steel Oyster bracelet—a sportier, less common alternative to the Jubilee bracelet typically seen on Datejusts of the era. The result is a refined yet slightly more utilitarian aesthetic. Accompanied by its original box and papers, and preserved in outstanding overall condition, this Datejust is more than a classic—it’s a piece of professional and horological history.
