Rolex black Waffle dial ref 6605

Dating to 1956, this Rolex Datejust Ref. 6605 in stainless steel combines a black honeycomb dial with a rare Jubilee bracelet bearing the Big Logo clasp. Also known as a waffle dial, its surface is formed by fine intersecting lines that create a dense, diamond-patterned relief. The texture changes with the angle of light, contrasting with the smooth facets of the applied hour markers and hands. Warm-toned luminous plots punctuate the outer track, while gilt-toned upper lettering stands against the black ground. A red date numeral beneath the Cyclops adds a further period detail.

Collector's Note

The Ref. 6605 belongs to a formative generation of the Datejust, preceding the long-running 1600 series. Its adoption of Calibre 1065 marked a technical development from the earlier Ref. 6305, bringing the distinctive butterfly-rotor automatic movement into the collection. The familiar 36 mm Oyster proportions were retained, linking these early references to the design language that would define the Datejust for decades. Textured honeycomb dials are documented within this generation and offer a notably different visual character from the plain silvered finishes often associated with the model.

The bracelet is an important part of this example. Its five-piece Jubilee construction contrasts broad outer links with narrower polished center sections, giving the steel watch a more articulated appearance. Inside the folding clasp, the oversized embossed Rolex name is enclosed within an elaborate scroll motif beneath a coronet. This is the feature described by collectors as Big Logo, a distinctive detail of early bracelet manufacture rather than simply a larger crown on the clasp cover. The combination of this uncommon clasp, the black relief-pattern dial, and the early Datejust reference gives the watch its particular collector interest. These details reward close inspection and distinguish it from later, more standardized Datejust configurations.
