Driven by the little lamp, this engine will rotate at speed around 1700-2000 RPM. It's assembled and will run within 5 minutes after opening the package provided you have a bottle of alcohol by your side.

It is a MINI version which can be put into your pocket. A little bit smaller than a 300ml Coca-Cola can. But do not be confused by its size, its quality and performance are guaranteed! We've done special treatment to the machine to avoid rusting and fading; use heat treated high grade spring steel stand to ensure its stability; employ thickened quartz glass cylinder and bearing steel rod to strengthen its robustness; specially designed Lever Mechanism and Crank-rocker Mechanism makes it more ”mechanical”.

It's also a perfect teaching tool demonstrating the process of energy exchange: the hot air in the sealed cylinder enables power piston to move continuously, and flywheel will spin at the same time; periodical air expansion and contraction makes heat energy converted to mechanical energy... Kids will be excited and curious about why. This will enlighten them to explore the world.

Watch is good, but it came with no instructions bc this is very confusing to figure out. Backlight is great effect and really nice for the value. Easy to see and read

Functional and great look!
Color: Black, Color: Black
This is my third watch I’ve had in the last 10 years. I bought my first one in 2014 when I was doing triathlons. My second one just died after surfing/working in a hospital with it for the last 3-4 years. I could of just changed the battery but for $40 and it will last, I thought hmmm let’s just get a new one. No complaints! Shipping arrived in 2 days, and the price can’t be beat. If you are looking for a simple watch to wear and not having to worry about getting it messed up this is it! I had a garmin 410xt that I had to charge etc but this watch is extremely convenient and comfortable. High recommend!

PERFECT
Color: Black
Watch is light weight. Has a good feel on the wrist and easy to read during the day and easy to read with the indigo back light at night. I have large wrists and this size is good. For smaller people it might be to large. The functions work well and its water tight. Its durable and keeps on ticking.
