Side-by-side comparison of specifications and features
Compare visual case presence and physical footprint on one shared wrist. Measure your top-down wrist width for a stronger result; lug-to-lug is used when the catalog has it.
Medium (6.7″)
Estimated top width: 56.7 mm
Preliminary range: 54.7–61.8 mm.

Proportional guide only: visual presence and physical footprint do not predict comfort. Weight, thickness, caseback shape, rigid lugs, strap stiffness, wrist-bone prominence, wearing tension, bezel design, and case curvature change how a watch actually wears. Non-round silhouettes use a verified family shape and catalog dimensions where available; missing case height or width is estimated from a conservative family aspect ratio.

Citizen Tsuyosa and Tissot PRX Powermatic 80 can overlap on price or use case, but the buying decision usually comes down to water-ready utility versus dressier everyday wear, casual character versus sports versatility, entry price versus premium finishing or specs. They both touch the sports use case, so smaller spec differences can matter more than brand preference.
Bottom line
Tissot PRX Powermatic 80 is the stronger watch if your budget allows: its finishing, clasp, longer power reserve, and 100m water resistance justify the upgrade. Buy Citizen Tsuyosa when value and a comfortable, colorful integrated-bracelet watch matter more than the clasp and movement upgrade.
