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.
Watch A
Visual presence

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.

This Tissot PR 100 vs Tissot PRX comparison is less about a universal winner and more about wrist presence versus easier fit, dress character versus sports versatility, entry price versus premium finishing or specs. They both touch the dress use case, so smaller spec differences can matter more than brand preference.

Tissot PR 100 — it is 40mm lug-to-lug versus 44.6mm, and lug-to-lug is what decides whether a watch overhangs a smaller wrist.
They are rated the same, so water resistance will not decide this. Choose on strap material and how much you mind scratching the case.
Tissot PR 100 is the value pick at roughly $150 less. Pay more only if a specific difference above matters to you — otherwise the cheaper one is the smarter buy. Confirm live listings, since marketplace pricing moves.
