On the Wrist, from off the Cuff: Seiko Marinemaster - SBDX017 'MM300' The OG Seiko Diver Grail 

Truly an icon, especially for us Seiko fanatics and modders. I always admired the MM300, Shogun, and Tuna from my SKX and SRP roots. After owning a MM300 my only complaint is the length of the bracelet links. It wraps around my wrist like a decagon.

Because of the smaller dial size on the MM300, it wears smaller than 44mm, more like a 40 or 42mm.

I agree with you. I think the 017 is the best looking of the MM300s. And if I had the disposable income, I wouldn't buy a Sub or a Seamaster, I'd buy this.

Superb watches the 300m is grail and the 200m is great

Such a good-looking watch. Masculine yet beautiful, with a design all its own.

I want a Marine Master. But, its out of my price range. Maybe somewhere down the line. 😢

Fortunate to have my 2004 SBDX001 Marine master. It has the the 8L35 movement.Also have the original 1968 6159-001.

The Marinemaster is a big beautiful beast of a watch!

My only issue with any model mm300 is the crown tube that is welded to case. If you ever have a threading issue, that whole mono block case needs to be replaced. In 2010 it cost $700 bucks, which means today it would not much less than the cost one of these preowned.

Love the MM200! Wish it had shorter L2L for us smaller wrist folks!

Just bought the 140th Anniversary in green . The Prospecx 300 Professional. Love it

Honestly I wish we had prospex X signed crowns, it'd be such a nice touch

thanks for this video, I've really been eyeing the newer SBDX043 and was curious how the dimensions compare to the mm200

The MM200 is basically what you get by taking the MM300 and removing everything that makes it attractive: the distortion of the crystal, the small, densly furnished dial, the depth of said dial, the chunky handset, the great bezel, the overengineered clasp, and the weird but attractive imbalance between the large, chunky case and the comparatively slim bracelet. Unlike the SPB143, which looks like a modernized version of the SLA017, the MM200 is just a lame version of the MM300.

The new ones are still called the marine master in the label as well as the new Japanese and american reference numbers.

now seiko just needs to do the og mm300 in a 39-40mm case and it would be game over.

Just ordered the SPB 185. Looking forward to it.

The reduced looks much better.better overall package.dont like the 6r35.have 2 of these and my 4r36 and 4r35 and my newest 4r34 run much better . The 300 has the proper caliber though
