The Rolex Datejust reference 1625, often affectionately referred to as the "Thunderbird," occupies a unique and coveted position within the pantheon of vintage Rolex watches. Its blend of classic Datejust elegance with the distinctive Turn-o-Graph feature, a rotating bezel with a luminous pip at 0, creates a timepiece that's both sophisticated and sporty. This article will delve into the fascinating history, design features, variations, and market value of the Rolex 1625 Datejust, exploring its enduring appeal and why it remains a highly sought-after collector's item.
Rolex Thunderbird 1625: A Legacy of Innovation
The nickname "Thunderbird" is not an official designation from Rolex, but rather a moniker bestowed by collectors due to the watch's striking resemblance to the sleek, futuristic design aesthetic often associated with the iconic 1960s television series, *Thunderbirds*. The sharp lines, balanced proportions, and the subtle yet noticeable presence of the rotating bezel contribute to this evocative comparison. However, the watch's true appeal lies far beyond its nickname; it represents a significant moment in Rolex's horological evolution.
The Rolex 1625 Datejust, produced from approximately 1961 to 1977, marked a transition period for the brand. It showcased the integration of several key features that would define subsequent Rolex models. Its 36mm Oyster case, a classic Rolex design element, provided robust protection for the movement within. The Jubilee bracelet, a five-piece link bracelet introduced by Rolex in 1945, offered both comfort and durability, further enhancing the watch's versatility. The inclusion of the date window at 3 o'clock, a hallmark of the Datejust line, added practical functionality. But it's the addition of the Turn-o-Graph bezel that truly sets the 1625 apart.
Rolex 1625 Datejust: The Turn-o-Graph Distinction
The Turn-o-Graph feature, a unidirectional rotating bezel with a luminous pip (often referred to as a "pearl") at 12 o'clock, added a dimension of functionality to the otherwise elegantly simple Datejust design. While primarily intended for timing elapsed durations, particularly useful for divers or pilots, the Turn-o-Graph bezel on the 1625 adds a subtle yet noticeable sporty touch. This unique blend of classic elegance and sporty functionality is a significant contributing factor to the watch's enduring popularity. The bezel itself often came in different materials depending on the specific iteration, with options ranging from stainless steel to gold, contributing to the variety seen within the reference 1625.
Unlike some later models, the 1625 Turn-o-Graph lacks the distinct "clicks" felt when rotating the bezel, a characteristic of later iterations of the Turn-o-Graph feature. This smoother operation contributes to the watch’s overall feel and is another element appreciated by collectors. The luminous pip on the bezel, often a contrasting color to the bezel itself, ensured excellent visibility in low-light conditions, further enhancing its practical utility.
