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
BoldCase covers 76% of your modeled wrist width.
Physical footprint
Near the edgeEstimated clearance: 3.9 mm per side.
Watch B
Visual presence
BoldCase covers 80% of your modeled wrist width.
Physical footprint
Clear spaceEstimated clearance: 4.8 mm per side.
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.
