The Baby Morpho was released in 1974 by Seiko, on the heels of the calibre 35 used in the Astron. Using the calibre 38 movement, the Baby Morpho was part of a more "affordable" quartz release to the masses. The Morpho dial is aptly named as it amazingly shows different hues on a spectrum, from aqua green to dark purple, depending on the angle of lighting. The dramatic faceted crystal adds to this visual effect, and the faceted case matches the overall design of this unique piece. The example shown comes on the rare original bracelet, which is easily adjustable with no tools.

The gonio-apparent (angle-dependent colour) visual effect is the standout feature of this piece. To this day, Seiko has still not disclosed how the dial was manufactured. In hand, the effect is stunning and there truly are no modern equivalents to this dial.
