The MM 017 is a beast. Bought it impulsively a few years ago. Haven’t worn it often. Put it on today and it’s fantastic

[WatchGeek]

Excellent comparison!!
I love the material upgrades of the new version but prefer the dial markings and writings of the old one

[setter]

Great comparison, as a 017 owner I'd like it if the crystal and bezel from the new models would fit the older ones. I do prefer the older dial with the marinemaster text.

[TomCorbett]

I d say that i agree with people who says the "X" on the dial is too much 'cause the crown is already signed.. i prefer to see the Marine Master written on the dial and a signed (Prospex) crown.

I love my SLA021 / SBDX023... dare say even more than my Omega Speedmaster as it gets more wrist time than all off my watches. Also, SEAL Team 10 guys wore MM300s... not sure if they bought them or what, but that was about 10yrs ago before I really got into watches.

Thanks for this excellent comparison video. After watching this video I bought a SLA021 myself...👍

I got my Seiko MM300 with the blue dial 21 days ago SLA023J1. I got it for a good price, and I wear it every day, I am totally happy with it! It looks and feels great.

Thanks for the video. This is exactly what I am looking for. I own the SBDX001 and now I am interested in the SLA021.

My friend first of all well done for the comparison review.
Your choice for getting the new over the old one is wise, upgrades are welcome. Also I would like to add that the insert on the SLA is zirconia ceramic which is even tougher than the normal ceramic. 😀

The crafter blue is definitely the way to go. It keeps the watch from sliding around and takes away the top heavy feeling it has when it's on the bracelet. The rubber has a nice vanilla smell also.

[superfast]

The MM300 is arguably the best diver under 10k. Yes, i rate it above the Sub!

[johnhealey]

Seiko MM’s are my favorite watch. They are so beautiful!

[adceal]

Great side by side review, Bob! The Marinemaster is a great watch. The new version has the sapphire crystal and ceramic bezel improvements. But, besides that, the watch is the same. A beautiful beast tool watch. Love it

Congratulations to the Raptors from this 76ers fan, we’ll see you in the playoffs next year. Nice review Bob👍

[reggievanness]

Good review. Hopefully i will own a Seiko Marine Master to add to my collection love the looks of both watches!

[floofycatz]

Thank you thank you, this is the first side by side of new vs old, good job!. I have the SBDX017, 0010. I had noticed the meatball indices on the SLA021 looked different than mine and I was thinking they were larger, but you gave me visual proof they aren't. It's like you pointed out, the metal ring is wider. It gives an impression the hour indices are smaller on the SBD017. thanx again :)

[OFD]

Such a great overview of both. The Raps were just beastly. I'm not going the injury route lol. Thanks dude. Now i definitely need a MM!!@🤣🤣🏀💪🏀💪

[dexson]

Congrats on getting one with +4spd ! Mine runs between +8 to +12spd ... oh well.. at some point ill send it back for regulation i guess. that being said, the specs are still within manufacture tolerance of within 15s. I heard but from unconfirmed sources that 8L35 is an unregulated ver of GS 9S movement so i guess with a little regulation it should work like a charm ! The problem will be on getting to the movement in the first place !

[Bitbythewatchbug]

A couple of beauties; Chris definitely knows what's up when it comes to Seiko! currently watching this alongside the champions parade!
