When Citizen first introduced the Tsuyosa in 2022, it carved out a clear lane for itself. Integrated steel sports watch styling, automatic movement, accessible price, and just enough personality to make it feel premium. It was easy to understand where it fit in the broader entry-level mechanical landscape. With the new Tsuyosa Shore, Citizen nudges that formula in a direction that feels strategic and just plain fun.
The headline change is simple: a unidirectional rotating bezel and an increase in water resistance from 50 meters to 100 meters. People will say this still isn’t a true dive watch; the crown remains push-pull, but the Shore now steps directly into the same practical territory occupied by watches like the modern Seiko 5 Sports dive-style models, which also run 100 meters of water resistance and skip the screw-down crown.
For years, Seiko has owned that affordable, dive-adjacent space. A watch that looks the part, handles the pool without complaint, and gives you a rotating bezel for timing pizza in the oven or tracking your kid’s swim lesson. The Tsuyosa Shore now plays in that same sandbox, but with a very different aesthetic starting point.
The core architecture of the Tsuyosa remains intact. You still get the 40mm case with its integrated, 1980s-leaning profile, brushed surfaces with polished accents, and the recessed crown at 4 o’clock. Sapphire crystal stays, complete with the magnifier over the date, and the caseback’s still transparent and screwed down. The addition of the rotating bezel pushes thickness from 11.70mm to 12.50mm, which is a reasonable trade-off for the added functionality.
Visually, that bezel changes everything. The smooth steel surround of the original Tsuyosa always gave it a slightly dressier lean, even if it was positioned as sporty. Adding a 60-minute scale on a color-matched metallic insert gives the Shore a more tool-forward attitude. It feels less like an integrated sports watch borrowing cues from the luxury segment and more like a summer-ready daily wearer that happens to be integrated.
The dial itself sticks close to the established formula. Sunray brushing remains, applied markers and luminous hands are still present, and the minute track’s been slightly revised with a more detailed sub-second track. The hour and minute hands are larger now, and the seconds hand adopts a lollipop design that reinforces the sportier vibe.
Color is where Citizen leans into the seasonal angle. There are two straightforward steel models, one in navy blue and one in a lighter marine blue that edges toward turquoise. Then things get bolder with a coral red dial and bezel paired to a two-tone steel and yellow gold color-plated case and bracelet. Finally, there’s a fully gold-tone model matched with a moss green dial and bezel. At prices ranging from $495 in steel to $550 for the fully plated version, this feels like experimentation without financial risk.
Inside, the Tsuyosa Shore runs on the familiar in-house Calibre 8210. It beats at 3Hz and offers roughly 42 hours of power reserve. There aren’t any upgrades here, and that’s probably intentional. The 8210’s a known, durable workhorse in this segment. In the context of a budget automatic with 100 meters of water resistance and a rotating bezel, it feels appropriate.
The more I look at the Tsuyosa Shore, the more it reads as a calculated move against Seiko’s accessible dive-style dominance. It doesn’t try to out-spec the Seiko 5 Sports line, and it doesn’t suddenly transform into a professional dive instrument. Instead, it meets it feature for feature where most buyers actually live. Push-pull crown, 100 meters of water resistance, automatic movement, rotating bezel, and a price that I think is easy to live with. By the way… I still feel this kind of watch can handle the average recreational dive. People get too crazy about water resistance and screw-down crowns.
From a collector standpoint, that makes the Shore interesting. If you prefer the integrated bracelet aesthetic but still want the casual utility of a timing bezel and pool-ready specs, Citizen now gives you an option that previously didn’t exist in this side of the catalog. It’s less about turning the Tsuyosa into a diver and more about broadening its legitimacy as a carefree summer watch. Gimme the dark blue one!
