With Patek Philippe Extract from the Archives confirming production of the present watch with enamel dial and laped hour markers in 1958 and its subsequent sale on 26 September 1958.
Patek Philippe post-war wristwatches made with plain enamel dials are a rarity. Collectors around the world associate only two "time only" models with this highly elegant yet uncommon feature, costly to manufacture and sensitive to careless handling: the celebrated reference 2526 and its successor reference 3428.
Reference 2577, the third in this league, must however be considered one of Patek Philippe's rarest models ever made. According to literature, its production was launched in 1958, in fact the year of manufacture of the present watch. The model went most likely never beyond either a prototype or "special order" status as until to date. Only two examples of this ultra-rare reference are known to have survived in pink gold cases and two examples in yellow gold, one of them being the present watch.
