Gentlemen,
In 1995, Patek Philippe unveiled a new reference, the 5004. It was a very complicated piece with Split-second chronograph and Perpetual calendar functions based on the Nouvelle Lemania caliber.
This caliber CHR 27-70 Q (30 x 8.86mm) was equipped with an isolator (patented) combined to the Split-second function in order to have a lesser impact over the chronometric performance of the watch.
The finishing is trully amazing and the very "tight" construction was really hard to assemble.
The CHR 27-70 Q caliber
The watch being 36.7mm wide looked quite thick at the time. If you remember, the 3970 (Chronograph and Perpetual Calendar) was 36mm.

But they were not the only versions to be produced as the watch was finally available in Steel in 50 pieces to celebrate the end of the reference 5004 and sold only at the Geneva Patek salon.

This reference has been replaced in 2012 by the 5204 reference.
Happy 20 years birthday!
