The present pink gold example of reference 130 not only impresses with its rare case material and wonderful condition, but it furthermore sports one of the most unusual dials found in the reference. The model is most usually seen with Arabic numerals at 12 and 6 and short baton numerals for the rest, or with Roman numerals at 12 and 6 and dot numerals for the rest. Many other dial variations are known though, including sector dials, Breguet dials, and variations of the 2 above mentioned designs.

An example of the former category, the present dial features Roman numerals at 12 and 6 (instead of the Arabic ones more commonly found in conjunction with baton numerals) and thin long baton numerals which at 2, 4, 8 and 10 o’clock arrive to graze the edge of the subsidiary dials. The difference with short baton dials is apparent and enormous, granting the watch a markedly more refined look - in contrast with the more sporty looks of short baton numerals. Reference 130 was the first serially produced Patek Philippe chronograph. Launched in 1934, some of the earliest examples were custom-ordered and occasionally featured a Victorin Piguet ébauche. Shortly thereafter, the model was powered by a heavily modified Valjoux movement, cal. 13 130, designed to fit within the reference 130 case.

The gold cases were crafted by one of the finest casemakers of the time, Emile Vichet, marked by the number 9 inside a key stamped on the inner case back.
