Accompanied by an Extract from the Archives confirming production in 1998 and sale on September 25th of that year. Together with a fitted wooden presentation box and corresponding key with outer packaging.

Ref. 5029 was launched in 1997 and produced in very limited numbers. Patek Philippe's promotional literature notes that only thirty pieces were created in total, with ten pieces cased in platinum, white and yellow gold, respectively.

According to our research, the present example is one of four yellow gold examples from this model to appear at auction. To the best of our knowledge, this is the first time the present example has been offered at auction.

The understated design of Ref. 5029 belies the complexity of the movement it houses. This model combines the time-honored tradition of minute-repeating watches with the contemporary desire for self-winding wristwatches.

In order to fulfill both of these demands, Patek Philippe designed the cal. R27PS movement, which utilizes an offset rotor to allow space for the minute-repeating gongs. Ensuring the chime's clarity of sound is a significant challenge in the creation of any minute-repeating timepiece. To meet this challenge, Patek Philippe tested a multitude of alloys, finally developing a new acoustic steel for the sole purpose of minute-repeating gongs.  

In the conception of a minute-repeating watch, the case maker must keep the clarity of sound in mind in addition to the numerous technical and aesthetic demands of the craft. The present model achieves an incredibly clear chime within a hinged Officer's-style case, whose cuvette and straight, screw-set lugs recalls some of the first wristwatches produced by the firm.

The case of the present Ref. 5029 was made by the celebrated Jean-Pierre Hagmann, whose case maker's mark, JHP, is stamped on the inside of the hinged case back.
