Equipped with the Manufacture micro-rotor caliber CMM.20, this sleeker version of the historic Navygraf model features a completely redesigned and thinner 39mm case with elegant finishes and a mother-of-pearl dial and bezel protected by a scratch-resistant double-domed sapphire crystal. This slim and versatile interpretation of the Navygraf fits all wrists and makes a sophisticated statement when worn with formal attire. Crafted from natural mother-of-pearl, the dial shimmers with delicate iridescence, revealing unique hues that shift with every movement of the wrist. No two dials are ever identical, making each watch truly one of a kind. The smooth, lustrous surface captures light in tones of silver, violet, and dark blue, adding an elegant depth and sophistication to the design.
