The new collection, featuring a total of nine models, is notable for its shared use of gradient-colored dials. The smoky hues, which darken towards the outer edge, are combined with a sunray finish, creating a subtle shift in color. Furthermore, the gold-toned hands and indices on each model create a visually striking contrast.
The case comes in three variations: 42mm, 40mm, and 36mm in diameter. The largest 42mm model is available in two colors: "Smoky Silver," which highlights the presence of the hands and indices, and "Smoky Brown," which emphasizes a vintage feel.
