Citizen Tsuyosa Watch Guide
This is a supporting guide to our Citizen Brand Guide.
The Citizen Tsuyosa is an automatic mechanical watch collection featuring an integrated bracelet design, positioned as an accessible entry point to Japanese mechanical watchmaking. Launched in 2022, the name derives from the Japanese word for “strength.”
Design Language
Tonneau Case
Barrel-shaped rather than angular — a softer, rounder profile that reads as dressy-casual rather than purely sporty.
4 O’Clock Crown
Recessed position prevents the crown pressing into the back of the hand during wrist flexion and maintains symmetrical silhouette.
Integrated Bracelet
Three-link “President-style” with brushed outer links and polished centre links. Small Second models include quick-release for tool-free strap changes.
Exhibition Caseback
All models feature a transparent caseback for viewing the mechanical movement in action.
Model Range
| Model | Size | Power Reserve | Feature |
|---|---|---|---|
| Tsuyosa Standard | 40mm | ~42 hours | Sunray dial, original model |
| Tsuyosa Small Second | 40mm | 60 hours | Sub-seconds at 6, guiloché dial, quick-release |
| Tsuyosa 60 | 40mm | 60 hours | Central seconds, geometric texture |
| Tsuyosa 37mm | 37mm | ~42 hours | Compact sizing, vintage proportions |
Sizing Note
The 40mm model’s integrated bracelet creates an effective wearing length of ~49–50mm. The 37mm variant dramatically reduces this, making it suitable for smaller wrists or vintage proportions.
Dial Options
The Tsuyosa emphasises colour variety: Black, Blue, Green, Yellow, Turquoise (“Ice Blue”), plus textured Art Deco patterns on Small Second and Tsuyosa 60 models. Limited editions include Pantone “Nowstalgia” collaboration colourways.

Frequently Asked Questions
Is the Tsuyosa automatic or quartz?
The Tsuyosa is automatic (mechanical). It winds via wrist motion and has an exhibition caseback to view the movement. Unlike Eco-Drive models, it does not use solar charging.
Can I swim with a Tsuyosa?
The Tsuyosa is rated to 50m (5 bar), suitable for daily wear and surface swimming. It is not recommended for diving. For water-focused use, consider the Promaster Marine collection.
What is the power reserve?
Standard models hold ~42 hours; Small Second and Tsuyosa 60 models hold 60 hours. If unworn for longer than this, the watch will stop and need restarting.
