As far as we know, there aren’t many brands who flat out refuse to put a date window on their watches. In certain categories like dress and field watches, the absence of a date keeps a cleaner dial and/or improves legibility at a glance. But still, there are always exceptions.
French luxury brand Serica didn’t just save date windows for select models, but said no to the feature altogether, all in the name of symmetry. Well, that day is now over, as the watchmaker has decided to put an aperture on its famed diving chronometer.
It’s a Date!
Founded in 2019 by Patrik Hoffmann, a veteran who cut his teeth at Nomos Glashutte and Akrivia, Serica built its reputation on an almost dogmatic commitment to symmetrical dial design. As the brand’s second-ever model, the original Ref. 5303 launched in 2021 with what Hoffmann called “dial furniture” positioned with clockwork precision at 3, 6, 9, and 12 o’clock. No date window was going to disrupt that grid. Even the GMT didn’t get one, which is a rare sight for a travel watch.
The new Ref. 5330 Diving Chronometer Date is an evolution of the 5303, and it does far more than simply punch a hole in the dial.
A Redesign That Earns Its Asymmetry
The date sits at 3 o’clock in an unframed window, with red numerals on a white disc. It’s a pop of color on an otherwise monochromatic watch. Where other brands treat the date as an afterthought, Serica recentered the entire minute track to compensate for the aperture’s presence, which keeps the dial from feeling unbalanced. The lollipop hour markers and broad arrow hands remain, but the dial itself is now matte black rather than the glossy enamel you find on the no-date 5303. This design was deliberate, optimizing for better legibility with the added complication in the mix.
The bezel got a quiet but welcomed rework as well. It’s still the dual-function setup with an inner steel 12-hour ring and outer rotating insert, but the countdown markings from 45 to 0 are gone, replaced by a cleaner (and more symmetrical) 60-minute count-up scale. The ceramic insert also debuts in anthracite gray with a faded gradient, which brings a softer aesthetic to what was already a pretty darn handsome case.
Don’t Fix What Isn’t Broken
The case carries over from the 5303 without changing anything. At 39mm across, 12.2mm thick, and 46.5mm lug-to-lug, these proportions have always been one of Serica’s strongest selling points. Twisted lugs with polished chamfers, a screw-down crown, double-domed sapphire crystal at 2mm thick, and 300m water resistance all stay intact. Lume placement is limited to the hands and hour markers, in the form of Super-LumiNova C3 that glows green. The 50,000 A/m magnetic resistance is a detail that often gets overlooked but speaks directly to the tool-watch ethos the brand has maintained since day one.
Inside is the SoProd M100, running at 4Hz with a 42-hour power reserve and COSC chronometer certification. It’s a dependable Swiss automatic that slots in as a well-regarded alternative to the ETA 2824, and the date version fits the 5330’s new complication cleanly. We should also point out that because of the date mechanism, the left-hand destro crown configuration that Serica offered on previous Diving Chronometers is no longer available, at least for now.
Two Straps, One Strong First Impression
The 5330 ships with Serica’s Vesper flat-mesh bracelet, the same tapering woven steel with integrated, articulating end links found across the Diving Chronometer lineup. It’s one of the better steel mesh executions at this price point. So you can dress it down too, the watch also includes a Polar White PLD strap with a red stripe that complements the date numerals.

Recap
Serica Ref. 5330 Diving Chronometer with Date
Serica just dropped their first-ever watch with a date window, the Ref. 5330 Diving Chronometer Date, which is based on their first diver from 2021. This is a big deal for a brand that famously refused to put one on anything.
