Patek Philippe, Reference 2573 and variations

This reference is launched in 1956 and remained in production until circa 1971.

This round-shaped watch is fitted with three different calibres:

· Ref. 2573, from 1956 to 1961, with Cal. 10-200.

· Ref. 2573-0, idem, with metal bracelet.

· Ref. 2573-1, from 1956 to circa 1970, with Cal. 23-300 (without subsidiary seconds at 6).

· Ref. 2573-2, from 1961 to circa 1971, with Cal. 23-300 PS (with subsidiary seconds at 6).

The majority in yellow gold, more rarely in pink gold and white gold, even more rarely in platinum (of which only two examples are known: one under Ref. 2573-1, the other under Ref. 2573-2).

Extremely few examples were produced with diamond-set dial.

A few other watches with an integrated metal bracelet have been produced, under Ref. 2573-5 for example.

The watch is so-called “Flat” by collectors.
