One of watchmaking’s simplest but most iconic complications, the date window, is the source of much admiration, and yes, a little bit of ire. One of the biggest points of contention on any inclusion of a date window is the balancing of it on the dial; after all, how do you place it to not ruin the symmetry (or asymmetry) of a carefully-crafted design? With their new Ref. 5330 Dive Chronometer, Serica has chosen a sleek solution for their first date window inclusion: nestle it at 3 o’clock, taking the place of the marker, and give it a crisp red accent to stand out. Sure, it’s not necessarily revolutionary, but it adds a sophisticated touch to an already clean dial.
The core tenets of the 5330’s design carry over from other models in Serica’s Dive Chronometer lineup, with circular hour markers and a double graduation bezel being the most recognizable, and a 39mm 316L stainless steel case housing an identical SoProd M100 Swiss automatic movement. The matte black dial and anthracite-grey outer bezel ring contrast with the steel of the inner bezel and case, and the cream Super-LumiNova on the hands and hour markers. Similarly, the cream date window and red numeral add both a sense of cohesion and a highly legible flash of color to give the dial an extra layer of aesthetic complication. It’s certainly a welcome addition visually, and keeps the design from feeling too austere.
At 12.2mm in thickness and 46.5mm lug-to-lug, the 5330 is sized well for most wrists, and should be very comfortable on the provided 20mm Vesper stainless steel mesh bracelet. For the more adventurous at heart, a Serica PLD white and red elastic nylon strap is also included, and it transforms the 5330 from a dressy piece into a proper explorer’s watch, a designation that comes with pedigree, since French adventurer Alexandre Gaye will be wearing the watch on his full solo crossing of Iceland’s Vatnajökull glacier in April 2026. Coined the Serica Isskrimsli Expedition, it covers 180 kilometers and will be completed by Gaye without any outside assistance. It makes sense, then, that the 5330 comes with proper rugged dive watch specifications, including 300 meters of water resistance. The date window will surely come in handy too, helping Gaye and any potential 5330 owners keep track of their place in the month, whether powering through whiteout conditions on a glacier or just counting down the days to the next long weekend.
All-in-all, while providing only a small addition to the already-handsome Dive Chronometer line, the Ref. 5330 is a smart evolution of the watch’s design and should make it appeal to even more enthusiasts. The Serica Ref. 5330 Dive Chronometer retails for $2,001 and is available on Serica’s website.
