The ref. 5050 is a highly collectible model, introduced at Baselworld in 1993 as Patek Philippe’s first serially produced perpetual calendar wristwatch with moon phases and retrograde date. The reference was released in yellow, pink and white gold, as well as platinum. Each engraved with the case maker key number 115, all ref. 5050 cases were manufactured by Favre-Perret.

According to research, only an estimated 150 examples were dressed in pink gold, spread across three series throughout its nine-year production run. An evolution of the ref. 5050 can be noticed with the first series featuring thin painted roman numerals, while the second series is defined by the applied baton indexes with an “Automatic” designation below the moon phase. The third series, as per this pink gold example, has applied Roman numerals and excludes the “Automatic” signature. Amongst the series, the configuration with applied Roman numerals are considered rarer (approx. 25% within the production) and therefore more sought-after by collectors.

The present example in pink gold offered in excellent condition with its Extract from the Archives confirming its date of manufacture in 1999 is not only a fine example of the series but is also a highly collectable timepiece with understated elegance.
