Datejust has evolved and changed frequently over the years. The very earliest examples, such as this reference 6104 which dates to 1953, the "offiacial" was inscribed in red letters similar to the very first Submariner Date and Sea-Dweller watches.
This two-tone reference 6104 also features both a dial and case that are entirely emblematic of early Datejust watches. The “Ovettone” nickname (which roughly translates to “big egg”) refers to the model’s protruding, curved case-back – a necessary design touch that was required to accommodate Rolex’s early self-winding system.
Combined with the 6104’s curved acrylic crystal, the overall shape is somewhat reminiscent of an egg. However, with a case diameter of 36mm, the ref. 6104 is also larger than the traditional “Bubble Back” Oyster Perpetual references. Unlike modern Datejust dials, the dial fitted to this particular reference 6104 features raised, arrow-shaped markers, an elongated coronet insignia, and a matte white surface that has developed a warm “tropical” patina over the years. It has been paired with our gray pigskin strap.
The fact that this watch is almost seventy years old and still retains its original components such as its red text dial and matching red calendar wheel is already impressive.
