The early years of the Rolex Datejust produced some of the most charismatic watches in the company's history, particularly the substantial, rounded references that collectors affectionately call 'Ovettone'. Meaning 'big egg' in Italian, the nickname describes the distinctive case architecture of these early self-winding date watches, whose pronounced case backs accommodated the automatic movement and calendar mechanism. Introduced in the years following the Datejust's debut in 1945, the ref. 6105 represents an important stage in the evolution of one of Rolex's most enduring designs. With its generous 36mm case, substantial proportions and characteristic bezel, it established much of the visual identity that would come to define the Datejust.

Dating to 1953, this example is particularly striking in 18K yellow gold, with a black gilt dial featuring applied arrow-shaped hour markers and elegant dagger hands. The contrast between the dark dial and warm gold furniture gives the watch a distinctly different personality from the more commonly encountered silvered configurations. Equally appealing is its matching yellow gold Rolex Jubilee bracelet, with a clasp stamped 4-53, dating it to the fourth quarter of 1953. Together, the substantial gold case, dramatic dial and period bracelet create a wonderfully cohesive example of early Rolex luxury watchmaking, from a period when the Datejust was still establishing the design language that would make it an enduring icon.
