In addition, this clock has no superfluous second time zone, which can play a nasty pranks.
With an alarm clock, stopwatch and 24 24-hour countdown it is limited to the most useful additional functions.
An almost elegant clock: black color, lighting with 2 orange-yellow LEDs, medium-sized dimensions, simple oval shape with a flat surface, dispensing with protruding frame and tassels and focus on a few labels.
25g weight and 9mm thickness is just about acceptable.
Plastic strap, waterproof for swimming and 3 years battery make a sustained clock.
