Product Details
The SUB 200T Diamonds collection remains true to the original SUB line’s DNA, while embracing modern style and elegance with a more compact diameter. The bezel on each of the seven models in the collection reflects masterful craftsmanship, set with 107 diamonds alongside 13 brilliant-colored gemstones or additional diamonds.
This careful gem-setting beautifully complements the iridescence of the dial made from natural mother-of-pearl. This noble material imbues each SUB 200T dial with an aura of grace and elegance, accentuated by its ever-changing luster. Sourced from the ocean's depths, it reveals a unique interplay of colors and textures, shaped by the shell it originated from. This gives each watch its own distinct character, making no two pieces the same and adding a level of bespoke exclusivity.
Designed with a refined 39mm case and 10.70mm thickness for comfort, the watch features a 316L stainless steel construction, Swiss automatic movement, 38-hour power reserve, and elements like a date window, unidirectional rotating bezel, and screw-down crown. It’s water-resistant to 200 meters, with a scratch-resistant sapphire crystal and Super-LumiNova® coating for optimal readability. The enhanced dial with applied hour markers adds a touch of sophistication, highlighted by the sparkle of the mother-of-pearl dial.
