OBLVLOJorker Men's Creative Design Big Joker Dial Mechanical Automatic Watches Leather Waterproof Luminous Sport Watch JM

I love the Chaykin Joker, but not the price. I took a punt on this watch for the price it is. I have to say I am amazed at the quality. The movement is actually a modified NH35, so actually it a bad movement. The lume is fantastic, the strap quality is even good.You cannot go wrong with this watch at this price.

I've written many times to the maker of this watch asking them to confirm that the crystal is sapphire. I asked them because there are reviews showing the crystal is not sapphire. I take the lack of a reply as confirmation that they are duping customers with a mineral crystal rather than the claimed sapphire one listed in the product details. As such I won't buy from this maker.
