What to know
The white Mastercraft J3 keeps the dial pale and finely textured, allowing the raised metal markers to cast small shadows across it. A polished circular bezel sits inside the compact cushion-shaped case, creating a clear contrast between the two outlines.

The steel case measures 37 mm across and 9.9 mm thick. A Miyota 90S5 automatic provides approximately 42 hours of reserve, protected by sapphire and 50-metre water resistance. The light dial gives this version a restrained appearance, with blue-glowing luminous material on the hands and markers.
