Funny little watch! Case middle and crystal is plastic, steel case back. Very light! Has a stop watch, dual time, hourly signal, the Alarm is loud. Water resistant. Simple but sturdy japanese movement, cased by Uncle Chang. No trimmer to adjust the rate but it's running at +0.05 s/d so that's pretty accurate.
The hands came in gold color but in low light difficult to see so I've pained them black and now it's perfect!
