Ulysse Nardin Maxi Marine Diver

The Maxi Marine Diver is a diving collection from Ulysse Nardin, the Swiss manufacture founded in 1846 in Le Locle, whose reputation was built on marine chronometers. That heritage is visible on the dial: a power reserve indicator at 12 o'clock, small seconds with a date window at 6 o'clock, and a wave-pattern guilloché surface. The line transfers this instrument layout into a large diving case — which is what sets it apart from conventional divers.

The main choices are case material, diameter and strap. The two-tone version combines stainless steel with 18 ct rose gold in a 45 mm case, with sapphire crystal, a black dial and a rubber strap with gold inserts and a folding clasp in rose gold and titanium. The bezel with raised markings rotates in one direction, the screw-down crown is protected by guards, and water resistance is 200 metres. Inside is the automatic calibre UN-26, based on the ETA 2892A2 with the brand's own power reserve module; the movement is COSC-certified, meaning its accuracy has been independently tested, and it runs for 42 hours.

Each listing gives the condition, what is included, the reference, calibre, case size, power reserve and strap.
