The Serica Ref. 5330 is the brand’s first dive watch with a date, introduced in early 2026 alongside the existing 5303. It shares the 5303’s 316L stainless steel case: 39 mm in diameter, 12.2 mm thick with the double-domed sapphire crystal, 46.5 mm lug-to-lug, 20 mm lug width, 300 m (30 ATM) water resistance and antimagnetic construction. The black matte dial has a date at 3 o’clock, and the bezel carries an anthracite grey ceramic insert with a twin 60-minute and 12-hour scale. Inside is the COSC-certified Soprod M100 automatic (28,800 vph, 25 jewels, 42 hours), and the watch comes on the Vesper woven steel mesh bracelet. Serica lists it at 1,690 EUR.

Monochrome, Gear Patrol, Worn & Wound and The Calibrated Wrist covered the launch positively; the main debate was whether a date belongs on a dive watch, and reviewers noted that the minute track was recentered to preserve legibility. The date mechanism means the left-hand crown option offered on earlier divers is not currently available.

The 5330 is in Serica’s current line-up and does not replace the no-date 5303, but both size variants are currently shown as sold out on the official store.
