Key Features:

• Ultra-Thin Perpetual Calendar Logic: Despite the mechanical complexity of tracking days, months, leap years, and moon phases, JLC has maintained a sleek 11.97mm profile, ensuring it fits comfortably under a shirt cuff.

• Dual Hemisphere Moon Phase: A standout astronomical complication showing the moon's progression in both the Northern and Southern hemispheres, featuring a retrograde display for the Southern half.

• The "Red Security Zone" Indicator: Located near the center of the dial, this safety feature alerts the wearer when it is unsafe to adjust the calendar settings (typically between 8 PM and 4 AM) to prevent damaging the delicate gear train.

• In-House Calibre 868: A legendary movement updated for the Polaris line, offering a robust 70-hour power reserve and a high level of finishing visible through the sapphire caseback.

• Four-Subdial Layout: The dial remains highly legible despite the wealth of information, featuring dedicated displays for the month/year, day of the week, date, and moon phases.

• Rotating Inner Rehaut: Managed by the secondary crown, the internal bezel allows for timing events or tracking a second time zone informally, staying true to the Polaris diving heritage.

• Gradient Blue Grained Dial: The multi-textured blue dial transitions from a lighter center to a dark periphery, providing a stunning backdrop for the rhodium-plated hands and markers.
