Sicura’s Hexa 400 Sea Green, reference H400.SS.A.40ATM.04.SS, adds a matte green dial to the revived brand’s dual-bezel dive watch. Fratello introduced the new color on October 29, following the collection’s earlier black, blue and orange versions. The Sea Green model retains the hexagonal case and paired screw-down crowns.

Two bezels with separate jobs

The external bezel turns in one direction and carries a diving scale on a black ceramic insert. An internal 12-hour ring provides a second time-zone reading: rotating its scale against the main hour hand establishes the offset. The upper crown, at two o’clock, moves that inner ring; the lower crown, at four, handles winding and setting.

A green-and-white surround borders the matte dial. Applied hour markers include an oversized numeral at twelve, with the date displayed at three. Sapphire glass receives multiple antireflective layers and an anti-fingerprint coating.

Separate luminous colors

The external bezel’s scale and numerals glow green, while the hour markers and hands emit blue light. This separates the elapsed-time markings from the ordinary time display after the luminous material has been charged.

The Swiss automatic movement operates at 28,800 vibrations per hour. Fratello identifies the mechanism as the 26-jewel SW200-1 and reports both manual winding and hacking seconds. Sicura specifies the Elaboré grade for this model.
