Comparison VST 738 vs VST 717

The colour of the characters displayed on the digital watch face screen (see "Watch Type"). Classic LCDs, most often used as such dials, have black characters — a variant familiar to almost anyone who has dealt with electronic watches. However, modern table clocks may provide other colour options — white, red, blue, green, orange(yellow), etc.; such colours are usually a sign that the dial uses permanently lit indicators and can be seen in the dark without additional illumination.

Some models of "coloured" watches are available in several versions that differ in the colour of the characters. But the colour change function, usually, is not found — it is quite difficult and expensive to provide such a setting in LCD screens that play the role of dials.
