Legendary Seiko Marinemaster SLA023 

Excellent 3 piece collection. Love the blue dial mm300. I have the black dial by the way.

Congratulations on your new job . The Seiko SLA023 is a beautiful watch. Wear in good health.

exactly the same watch in titanium id purchase in a heartbeat

Congratulations 🎈🎉🍾🎊. This is my grail watch as well. I hope to one day obtain this beauty.

Great video and yes the LX series is the new Seiko king but I am glad I went with my MM300

I just got mine this week- previously owned an sbdx017 and loved the “marinemaster” dial but always wanted the blue colour. The sapphire/ceramic upgrades along with being newer were also factors in swaying me back to this watch. Nearly got the black/green too and also love the blue pelagos/bb58 and speedy but having tried them all I came back to this. I sold my last mm300 a few years ago and justified the sale with all the imperfections and the price/profit I was offered after wearing it non stop for a year or so. But I’ve missed it since and have to say it’s one of the best looking watches I’ve ever owned and also one that gives me more enjoyment than any other. Perfectly imperfect in every way. I agree it doesn’t feel “too big”, but it does have a nice solid heft that I like (On my 7in wrist). The speedy and pelagos always felt borderline too big for me on the bracelet (wearable but not just right), probably as the lug to lug is not curved in the same way on those two as it is on the mm300. The Bb58 was perfect too despite being much smaller in spec but this mm300 dial just makes me smile and it’s hand polished and hand assembled. Enjoy yours 🥂(just liked and subscribed)

How would you describe the winding action on yours? Mine isn't rough, but compared to an Omega or a Nomos, it sounds as if I'm winding up a toy. Those other two watches don't make such a loud mechanical noise when I'm winding them.

Seiko divers are the best looking ones when you put it in rubber or leather, seiko bracelets arent good nor comfortable
