Launched in 1938, reference 570 was the first large Calatrava produced in series. In fact, watches measuring anything near 36mm were then seen as quite daring. While the model was cased predominantly in 18K yellow gold, it also existed in white or pink gold and stainless steel in small numbers but it is the first time that we see an example in 14K yellow gold with black dial. Confirmed by Patek Philippe’s archives, this possibly unique watch was made using 14K yellow gold and the very attractive pink shine results from the proportion of gold used in this alloy. Such cases were in general reserved for the Eastern European market.

Another particularity of 14K yellow gold cases is that they were made by a Geneva based company called Genevor, that produced cases with noticeable differences in the shape proportions compared to the 18K counterparts. The diameter of the present 570 is 0.5mm larger than the standard model, and it furthermore features thicker lugs.

In production for more than 30 years, this reference exists in many configurations, with multiple dials and movements featuring subsidiary seconds first, and centre seconds in later models. An early example, the present watch powered by a calibre 12-120 features subsidiary seconds. The watch’s stand out feature however, is its extraordinary black lacquered dial, beautifully accented with contrasting Arabic and baton hour markers. An extremely rare dial that is confirmed by the Extract from the Archives.

The case features two hallmarks on the side and one underneath the lug, underlining the excellent condition of the case.

The exquisite black dial of this possibly unique 14K yellow gold reference 570, combined with the watch’s beautifully preserved condition and freshness to the auction market makes this a very exciting trophy for all collectors.
