Perpetual Calendar Split Seconds Chronograph 5004 White Gold / White Arabic

In Context

At 36.7 mm it is classically proportioned: the size a dress watch was understood to be for most of the twentieth century, and small enough to sit under a cuff. The sapphire crystal will resist everything short of deliberate abuse.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 60 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 18,000 vph the seconds hand advances 5 times a second, the slower and more audible rate of an older design.

5004G-001 is one of 3 executions of the 5004G base reference. Underneath they are the same watch; what separates this one is a silver dial and a white gold case. Beyond the time it carries a chronograph and a perpetual calendar.

Patek's split-seconds chronograph, built on the Lemania 2310 ébauche — the same base under the standard CH 27-70 — with rattrapante works and a perpetual calendar added and all 407 parts finished in-house. CHR marks the split-seconds, Q the quantième perpétuel. It powered reference 5004 from 1996, a watch Patek could assemble at a rate of only about a dozen a year.

15 other watches in the library run the Patek Philippe CHR 27-70 Q.
