The sunray dial on this piece is a total standout, catching the light across a bright, airy blue surface that feels like an early afternoon sky. It packs a massive amount of watchmaking logic onto the display while keeping everything clean and easy to read. You get a double moon phase for both hemispheres at 12 o’clock, the date and a 7-day power reserve meter at 3, the month at 6, and a combined day and small seconds indicator at 9. There’s even a rare four-digit year window tucked away between 7 and 8 o’clock. Encased in polished 18K white gold, it pairs perfectly with its matching blue leather strap.
