    DD Sapphire Crystal Seiko Turtle

    Posted by Darren on Jun 16th 2021

    Will use Long Island for my second Seiko following this order. Sent to me in Wales UK and just fitted the crystal on my Turtle SPR777. Wish I'd done it way back as huge improvement. Great order experience with Long Island Watch. Com. Thanks guys.

    I emailed Long Island way to see if they would be able to help me replace my garden crystal on my flightmaster. Within a min of sending my email, Marc(The President) emails me back with the info I needed. Thanks Long Island Watch

    Blue AR Sapphire Crystal

    This crystal greatly improved the look and strength of my SRP777. The subtle blue tinge is perfect, not unnoticeable but not dark where it hinders the numbers. I highly recommend getting this Crystal to modify your watch.

    Piece of glass

    Posted by Sydney Roberts on Aug 3rd 2020

    It's rather difficult to review a piece of glass I put on my watch. The experience was fine - ordered, delivered and I used Mark's videos on YouTube to help me through the process. Looks much better and works fine. I'll buy from LIW again.

    In Mark I trust

    I've been following Long Island Watches since I started collecting watches and have become an avid watcher of Mark's YouTube channel. I recently purchased a double dome sapphire crystal and couldn't be happier with the product. I had been planning to buy one of the amazing quality Islanders watches prior to Covid but have had to put of it back a little while. I am looking forward to supporting Mark and his LIW brand into the future.

    Great looking Crystal

    Posted by Frank Zeuner on Jun 1st 2020

    No Mod is complete without a sapphire crystal. The double done crystal installed easily after watching Mark's video on changing the watch crystal. I just hope it's still waterproof. Thanks, the Samurai ooks great.
