Did you realise that some of the most valuable Patek Philippe watches ever made were in steel? This Antimagnetic ref.3419 has a unique (and patented!) case construction with removable lugs that allowed for the attachment of an 'integral' bracelet. This example in wonderfully crisp condition sports a remarkably clean silver opaline dial with unusual baton hands. Powered by Patek's manual wind cal.27-AM400 movement, this rare watch is presented with the extract from the Patek archives.
