IWC. An unusual, rare and attractive 18K white gold and diamond-set cushion-shaped bracelet watch with lapis lazuli dial and box

With IWC Certificate of Authenticity, confirming production of the present watch ref. 405 in white gold and diamonds on 6 September 1977, service invoice, and fitted presentation box.

This watch is a very rare and unusual model from IWC, characterized by its generous "TV-style" case and lapis lazuli dial. Resonating with an undeniable 1970s vibe, the timepiece is defined by its case construction, centered on the interplay of smooth polished metal surfaces and shiny diamond pavé. This is most evident in the bezel, with the two diamond pavé elements neatly delimited by polished metal borders. The dial, instead, is absolutely sparse, lacking even the IWC signature. This allows the lapis lazuli element to be the undisputed protagonist of the watch, its deep blue hue in stark contrast with the shine of the case. Such design is typical of this age, characterized by clean dials and innovative case designs.
