Accompanied by a Patek Philippe Extract from the Archives confirming production of the present watch in 1956 and its subsequent sale on April 23rd of the following year.
The Manta Ray was launched only in 1952 with several variations, from 2554-2 to 2554-10, until it was discontinued at the end of 1960s. Available in yellow, pink, white gold and platinum, the present example is among the rarest of all the variations.
This design is a perfect example of Gilbert Albert's design influence in Patek Philippe production of the 1960s, the case manufactured by Markowski, the well-known case maker specialized in shaped cases, and the dial, considered a work of art from the atelier of Stern Frères.
The streamlined Manta Ray shape, highly unusual for the period, served as inspiration for the celebrated reference 5100 10 Days model launched in 2000.
Another example of reference 2554 is described and illustrated in Patek Philippe Museum - Patek Philippe Watches, Volume II, p. 217
