A brief overview of the Seiko Marinemaster 300m SBDX001

This is a brief overview of one of my favorite divers, the Seiko Marinemaster SBDX001. I neglected to mention that it's a 300m diver and comes with a domed Hardlex crystal, which is basically a hardened mineral crystal. It can scratch, but will not shatter. It also works well in conjunction with Seiko Helium Escape system. More can be found on the net regarding this topic. Hope you like the video.

I really like the MarineMaster however the only thing holding me back is the lack of a sapphire crystal. Shatter resistance is not important to me because sapphire is still strong enough for everyday wear. Resistance to scratches is a much more pressing issue. If I pay $2000 for a watch, it needs to have a sapphire.

Email me if you want a source for installing a sapphire crystal made to the same specs of the hardlex. This is a hang up for a lot of people, but according to Seiko, it's done for a reason that would take me a while to explain right now. Thanks for your comments.

Thank you very much for taking the time to make this video. I really enjoyed it.

Along with the MM, the Orient Star 300m diver also uses the same ratcheting clasp. Rolex also put a similar clasp on the new "Deep Sea" Sea Dweller model. I'm fairly sure the MM has been in production since 2000.

Good to know! Appreciate the info.

I've 7S26's rate and beat error adjusted to about 3-4 seconds a day at worst, surely that can be adjust to even half that error? I mean sometimes I don't reset them any more often than after about 5 weeks because I don't notice it getting more than about 25 seconds off!

Informative review without being boring, thanks

Excellent review mate - my resistance to not buy one is weakening!!

Great video JP - thanks for the review. I could not believe the size of it when you compared it to your Sub, It would be too big for me, but it looks like a great watch. Cheers.

@GMCtrk im sure there is a $50 mod that changes the hardlex crystal out for a sapphire one.

Very true. A tritiume vials dial and hands will glow more steady, whereas Luminova and Lumibite for example will glow brightest after being charged (via natural light or some other light source) and then dimish as the hours pass. I stand by my statement that the watch will glow quite strong all night. Strong enough to be easily read, at any rate. Thanks for your comments.  Best, JP

The types of lume are different. Some manufacturers use a radioactive source, which is why they don't need to be activated by light. That is not necessarily a preferable solution, as seen in the fact that most high-end makers don't use it.

Excellent watch but, lume is not as good as my Ball Night Train. My Night Train lume is bright without using a light source.

Excellent and thorough description! Thank you!
