How we picked
Each watch earns points from published specs only: sapphire crystal (2), water resistance of 200 m or ISO 6425 diver certification (2; 100 m earns 1), screw-down crown (1), power reserve of 70 hours or more (1), display caseback (0.5), hacking plus hand-winding (0.5) and lug-to-lug of 47 mm or less (0.5). We rank by points, then by lower US list price. Near-identical colourways are grouped and we show the lowest-priced one. We cap each model family at two picks so the list isn't one watch in six colours.
