    Every time you hit on your watch, I can feel the shock wave on its movement… Poor Seiko ^^



  2. TechFanatic on December 17, 2021 at 10:14 am

    Hey chris, that bezel fade looks awesome! Did you fade it yourself or is it natural?



  3. Joe Silvia on December 17, 2021 at 10:15 am

    Now you should do a video on polly watch.



  4. Mark Stevens on December 17, 2021 at 10:16 am

    That why AR coatings should be on the underside…



  5. Faith Gil Torres on December 17, 2021 at 10:17 am

    Great vid. Made me feel happy with my recent upgrade to sapphire. Subscribed!



  6. Starlord85 on December 17, 2021 at 10:17 am

    Waste of time



  7. TechFanatic on December 17, 2021 at 10:18 am

    Seiko has no reason of putting mineral glass in their 250+ dollar watches. Its just to save costs. Orient divers starting from the kamasu all have sapphire, and there are even cheaper watches that have sapphire. And if they were really going for the "shatter resistance" like they say they do, then i would prefer they went with acrylic like the vostok amphibia for example. You can use polywatch to polish the scratches out, and it is more shatter resistant than mineral.



  8. jeremy inzeo on December 17, 2021 at 10:18 am

    Bought a $300 cocktail time with a hardlex. Got scratches. Never buying mineral crystal again unless its a cheap quartz like a Casio or Timex.



  9. Maximus on December 17, 2021 at 10:24 am

    My Seiko watch is scratched lime hell, the glass basically only consists of scratches at this point



  10. Dubstep Party on December 17, 2021 at 10:28 am

    Your watch startend working again… Now I know that works lol



  11. Lim Wei Leong on December 17, 2021 at 10:30 am

    Thanks for showing this video, Is good scratch test.



  12. Hyper on December 17, 2021 at 10:31 am

    Damn the difference is actually huge. I already refused to buy hardlex but there you have it.



  13. DzonHMF on December 17, 2021 at 10:33 am

    I’m working in factory producing electric engines and that means working with tools, sandpapers, different type of steel etc. My sapphire on my citizen is good as new, and it suffered a few knocks also and survived. I really don’t get it why seiko put sapphire one $500+ pieces only



  14. Max Sharbanov on December 17, 2021 at 10:33 am

    dude i nearly died ! hahaha thank you for the video i learned a lot!



  15. Emilio Aguilera on December 17, 2021 at 10:34 am

    thank you so much for this video



  16. Harsono Ng on December 17, 2021 at 10:34 am

    In conclusion Hardlex harder than mineral crystal is only marketing hoax



  17. Muscular Chicken on December 17, 2021 at 10:38 am

    Watches with sapphire crystal are expensive but totally worth it.



  18. This Life on December 17, 2021 at 10:38 am

    Great video–although I do think it’s funny that you used the crystal in your actual watch, rather than just ordering another cheap one for the test. As others have said, I appreciate you taking one for the team!



  19. Kevin Harrelson on December 17, 2021 at 10:38 am

    Watches will not come in contact with coral. Divers don’t wear dive watches. They wear dive COMPUTERS on their wrists. Think a G-shock scaled up a bit. LCD display showing depth, time remaining at that depths before needing decompression, etc. Some even have wireless transmitters attached to the regulator that will transmit the air left in the tank to the computer.



  20. Dc on December 17, 2021 at 10:38 am

    Making me so nervous watching u test your good seiko sapphire



  21. Douglas on December 17, 2021 at 10:39 am

    Interesting informative video. Thanks.



  22. Mark Fischer on December 17, 2021 at 10:39 am

    I’m honestly shocked at the durability of the AR coating. I have a couple watches with sapphire, no scratches in the glass but one has a single scratch in the AR coating. Definitely my crystal of choice. Actually getting my Citizen Avion fitted with sapphire



  23. Amin on December 17, 2021 at 10:40 am

    Thank you so much for this video Chris!



  24. EuPass Wood on December 17, 2021 at 10:40 am

    I don’t understand Seiko what they want from they "Hardlex?



  25. TL Pricescope on December 17, 2021 at 10:41 am

    Only Diamond or a sapphire can scratch the sapphire crystal.



  26. Bruh Bruh on December 17, 2021 at 10:43 am

    pretty cool I subbed!



  27. John dover on December 17, 2021 at 10:44 am

    Just for a heads up your screwdriver is not stainless steel



  28. blueconvoy on December 17, 2021 at 10:45 am

    Me at the point of the dremmel test. "You Sir deserve a subscription." Done.



  29. Matteo Favi on December 17, 2021 at 10:49 am

    ..and yet Seiko won’t give you a sapphire unless you give them at least 6-700€ for a watch. That is why I’ll hardly become a customer of them.



  30. MyEnemy on December 17, 2021 at 10:51 am

    I have a Sea Wolf that’s 30 years old and the saphire crystal is unblemished, nothing compares.



  31. A M on December 17, 2021 at 10:53 am

    Seiko hardlex is one the most useless invention



  32. Matt Reardon on December 17, 2021 at 10:55 am

    I work at a Watch repair shop in Scottsdale, AZ. We are authorized Seiko dealers, last week our Seiko rep came to our store and informed us that they are trying to use Sapphire more and more in there upcoming watch lines. Hardee’s will still be used. Also he informed me that the price point of Seikos will be increasing, the cheaper Seiko 5s with the 7s26 are being fazed out.



  33. J S on December 17, 2021 at 10:56 am

    Now that’s putting your money where your mouth is!!



  34. Minty Webb on December 17, 2021 at 10:57 am

    Sapphire is the best.



  35. Carl Tercak on December 17, 2021 at 11:02 am

    This screw driver isn’t stainless.. It’s either carbon steel or chromium-vanadium steel. Stainless is mostly common in knifes/blades.



  36. Jac ReviewsStuff on December 17, 2021 at 11:02 am

    Time to change the sapphire again XD



  37. Bao Nguyen on December 17, 2021 at 11:02 am

    Why don’t they apply reflective coating underside of the sapphire glass ?



  38. Dc on December 17, 2021 at 11:04 am

    Great video! Thanks for doing this



  39. kostek on December 17, 2021 at 11:09 am

    Many thanks for your sacrifice.



  40. Nath on December 17, 2021 at 11:09 am

    I can get scratches out off sapphire using a Dremel and diamond paste but it takes a lot off work!



  41. TechFanatic on December 17, 2021 at 11:11 am

    You should just get rid off the AR coating anyway now. A lot of people actually do this on purpose. Because the AR coating will probably scratch away anyway in the long run and will be annoying to look at.



  42. Shawn Lavigne on December 17, 2021 at 11:12 am

    I’ve never scratched sapphire. Everything else, yes. Seiko should stick to using hardlex on their case backs only.
