Measuring 40 x 38mm, the Nautilus 5711/1A-011 wears the distinctive porthole silhouette first conceived by Gérald Genta. The silvery-white dial features horizontal embossing, gold applied baton hour markers with luminous fill, and matching gold baton hands. A date display sits at 3 o'clock, framed by a stainless steel bezel and protected beneath a sapphire crystal.
Power comes from the self-winding Caliber 324 S C, offering approximately 45 hours of power reserve. A sapphire display case back allows a view of the movement within. The screw-down crown, 100-metre water resistance, and double-fold clasp on the stainless steel bracelet round out a thoroughly considered specification.
The 5711/1A-011 white dial variant has grown notably scarce since production shifted to the olive-green 5711/1A-014, making this reference a significant piece for Nautilus collectors. This example is offered complete with its original box and papers.
