I found this one: Heimdallr Ocean Monster Diver’s with day date, sapphire crystal, 200 m waterproof and a reliable Japanese (Seiko) automatic movement. The Jubilee bracelet looks great and fits perfectly because of the possibility of micro adjustments. No sharp edges or hair pulling with my watch! I like the dark blue dial with the silver Megalodon shark logo, it fits a diver’s watch. In the sun you will see a nice blue light beam shimmering over the dial. I have to admit it’s a little difficult to set the watch because of the crown protection but nothing really bothering or a reason to take one star off. Set it once and forget it because it’s a self-winding mechanical automatic watch as long as you wear it regularly. No need to change batteries ever because it has none! I tested the watch in the ocean and in the pool: totally waterproof. This is your every day watch for all occasions, ever. Review: Sapphire crystal - Your time with Seiko Hardlex ends here. Good luck my friend. ## Features - NH36A Movement: Stainless steel watches for men is powered by Japan 24 jewels fully automatic NH36A Movement, providing precise and accurate time keeping.
