The Ulysse Nardin Maxi Marine Diver 18k White Gold (Ref. 260-32) is a rare, highly collectible luxury timepiece limited to exactly 500 pieces worldwide. This model stands out for its exceptional heft, premium materials, and vibrant maritime styling, beautifully reflecting Ulysse Nardin's historical connection to marine chronometers. Key Specifications & Features

• Case & Bezel: A substantial 42.7mm (commonly classified as 43mm) case made entirely from solid 18k white gold. It features a matching solid white gold unidirectional rotating dive bezel. 

• The Dial: A vibrant, deep blue lacquer dial adorned with a distinctive checkered or wave pattern, heavily applied luminescent hour markers, and oversized skeletonized hands. 

• The Complications: Modeled after historical marine chronometers, the dial layout displays a power reserve indicator at the 12 o'clock position and a subsidiary small seconds dial at 6 o'clock. The circular date window sits neatly inside the 6 o'clock subdial, magnified by an under-crystal cyclops lens. 

• Movement: Powered by the Ulysse Nardin Caliber UN-26 automatic chronometer movement (built on a high-grade ETA 2892 base), providing a 42-hour power reserve. 

• Limited Edition Plaque: Each timepiece features a bolt-fixed, individually numbered plate on the left-hand side of the caseband identifying its specific production number out of the 500 total pieces.

• Straps & Wearability: While it originally retailed on a heavy blue rubber strap integrated with solid white gold elements and a deployment clasp, a tiny handful of special-order units were exceptionally delivered on a full 18k white gold bracelet, bringing the total wrist weight to an astonishing 11+ ounces. 

• Water Resistance: Built as a true luxury adventure watch with a screw-down crown, offering water resistance up to 200 meters (660 feet)
