Mondaine releases a new diver in blue

Mondaine has added a new seasonal color to its Numeri line, introducing the 42 mm model in what it calls BlueLake. The update does not change the underlying watch, but it shifts the tone of the piece. The Numeri has always leaned toward a structured, almost architectural design, and this version softens that slightly with a blue dial meant to reflect water.

The case remains 42 mm in 316L stainless steel, with a brushed top surface and polished sides. The defining feature is still the 12-sided fixed bezel, which gives the watch its identity. It is not a rotating dive bezel but a faceted frame with engraved numerals, more about form and legibility than function. That shape, paired with the blue dial, creates a contrast between rigid geometry and a more fluid color palette.
