Its mechanical heart is a precise and shock-resistant quartz movement, which is powered by a battery. The case is made of black plastic which is very light and resistant to small scratches and impacts.The black strap is made of silicone - the material which is characterised by lightness and high level of damage resistance. It perfectly goes with the watch case. The black dial is covered by a mineral crystal, which is renowned for its high resistance to shocks and scratches that are caused during everyday use. Due to a water resistance of 200 meters, the watch can be worn during swimming and freediving at greater depths.

    The watch is well made, I have nothing to complain about. Perfectly packed - nothing was to be damaged. At the moment I am satisfied. As for the fiance, time will tell, but it seems to me that he will have the same opinion as me. I want to point out that this is the third watch that he presents and two have not survived; p (previous watches were not purchased from you), but I give this a chance to survive, looking at a decent workmanship. To sum up, the photos added to the offer are not distorted, the shipment is quick and efficient, and you can take nothing more. I personally recommend. :)
