Built around the 5740/1G-001 reference in white gold, this replica Nautilus 57401G white 40mm delivers the perpetual calendar complication inside the coolest-toned version of the 5740 available. White gold case, white dial, and the ultra-thin 240 Q caliber combine to create a Nautilus that leans closer to dress watch territory while retaining every element of the sports-watch DNA Gerald Genta established in 1976.

Build Details

• Case diameter: 40mm
• Case material: white gold
• Dial: white with horizontal embossing
• Crystal: sapphire
• Movement: automatic perpetual calendar (based on 240 Q)
• Functions: hours, minutes, day, date, month, leap year, moon phase
• Micro-rotor winding system

White gold carries a heavier density than stainless steel, so even at 40mm the case has a more substantial wrist presence. The white dial against white gold creates a near-monochromatic silver palette that reads differently depending on ambient light.

What Collectors Notice

Three versions of the 5740/1G-001 exist: this white gold with white dial, rose gold with white dial, and rose gold with brown dial. White gold commands attention among collectors because it visually resembles steel from a distance but carries the weight and finishing of precious metal. The perpetual calendar displays remain identical across all three, but the white-on-white configuration makes the calendar apertures at 12 o’clock and the subdials stand out with maximum contrast. Compare across the entire Nautilus collection to understand where this sits. For a different complication approach at the same 40mm size, the 5712G-001 with baguette bezel trades the perpetual calendar for moon phase subdials and a diamond-set bezel.

This vs Other Versions

Choosing between the three 5740 variants comes down to color temperature. White gold with white dial is the coldest and most formal option. Rose gold with white dial splits the difference. Rose gold with brown is the warmest and most casual. The mechanical package stays identical across all three. This replica Nautilus 57401G white 40mm represents the most restrained and dressy execution of the Nautilus perpetual calendar, suited to anyone who values understatement over visual warmth.
