French independent Serica puts a date into its diving chronometer

Paris-based independent Serica has expanded its signature diver with the Ref. 5330, its first date-equipped diving chronometer. The red date numeral sits at three o’clock, becoming part of the otherwise monochrome layout rather than a distraction. Anthracite-grey ceramic softens the bezel against a matte black dial.

The 39 mm stainless-steel watch is 12.2 mm thick, with a manufacturer-stated 300 metres of water resistance. Its Soprod automatic movement is COSC-certified, while a woven steel bracelet and an additional elastic strap give the instrument two distinct personalities. Introduced in March 2026, this is a French-independent-maker spotlight rather than a new October launch.
