The movement is running, however it might require service soon. The dial has some light spots, but generally is clean. It appears to have been washed at some point as the signature is rather faint. The case is generally in nice, clean condition. There is light surface wear to the outside of the back and some light scuffs near the crown. The stamp between the lower lugs is nice and crisp. The case number is stamped on the profile of the movement. The interior of the bezel is also stamped 63, the last two digits of the case. The strap of this watch contains endangered species; please refer to Important Notices for further information.

Accompanied by an Extract from the Archives confirming production on 1958 and sale on October 3rd of the following year. 

Production of reference 2554 began in 1952. To commemorate the beginning of the third millennium, Patek Philippe re-issued the 2554 case design as the reference 5100, known as the Ten-Day.The fluid lines of the design echo that of a manta ray, whose image appears in the reference 5100's promotional material. For examples of Ref. 5100, see lots 162 and 163 in this sale.

The case of this watch was made by Markowski, one of the finest case makers in Geneva. In addition to this model, they were also responsible for the case production of other unusually shaped rectangular watches, including the 'Hour-Glass', Ref. 1593, the 'Top-Hat', Ref. 2480, the 'Tegola', Ref. 2461, and the 'Tegolino', Ref. 425.
