SEIKO Marine Master Professional 300M Automatic Diver with AR Sapphire Crystal #SBDX023

This is the newly upgraded Seiko Marine Master watch. It replaces the Seiko model SBDX017. It features a high grade Seiko 26-jewel automatic (8L35) movement, a date display, highly luminous hands and markers treated with Lumibrite for awesome low light visibility, a screw down offset crown, a uni-directional diving bezel with luminous PIP at 12:00, and a solid etched case back. The premium 8L35 Seiko movement is self-winding, hacks, and it can be hand wound. The movement has a 50 hour power reserve and it is very accurate to +15 to -10 seconds per day.

This new version now has a new deeper black dial with an anti-reflective coated (inside) sapphire crystal that provides increased clarity compared to the hardlex used in the older Marine Masters. You will also notice that the bezel now has a ceramic insert with Lumibrite applied to the markers on the first 20 minutes.

The watch comes on a stainless steel bracelet with a double locking fold-over push-button clasp with a divers extension. It includes manual, an extra rubber strap and a Seiko Prospex box.

Finally a MM with all the improvements April 11, 2019
Reviewer: Mike from Valley Stream, NY United States  
I have always want a MM300 but the Sbdx 017 had the Harlem crystal and aluminum bezel insert. Now the newt model the 023 has all the upgrades I was looking for so after researching the internet and some reviews . I saw Marc from longisland watch.  He comes across with honesty that you do not see this often in today’s world.
What can I say ! Fast Honest transaction !
Great communication too on other purchases .
