The legendary "Steel King" Nautilus 5711/1A, meticulously replicated in this Taiwan Factory Ultimate Version. This 40mm masterpiece boasts an incredibly precise 8.8mm thickness, mirroring the original perfectly. It features significant dial upgrades over previous market versions, including pure white luminous markers with subtly green-tinted hands, and a perfectly centered, enlarged calendar window for flawless legibility. The see-through sapphire case back reveals a heavily modified 9015 automatic movement, decorated as the Patek Philippe Cal.324. This is currently the only market version featuring a corrected balance wheel orientation, alongside meticulously polished bridges, exquisite Geneva stripes, and vibrant jewels. A masterclass in understated, sophisticated design for everyday wear.
