SLA023J1 Seiko Marinemaster 300 1 Year 7 Months Later Review 

Since it is a Seiko I'm sure you could do a 10 year review and it will still be ticking.

This is the best Seiko dive watch without a doubt. You need to live with it to appreciate it. I have the SLA021J for 3 years now and accuracy is same since day 1. Excellent video by the way.

Gorgeous watch, certainly worth every cent. Really good review, love your detailed analysis and especially good macro photography. Thank you 🙏 😊

Nice review. Thanks for taking time to make it.

I totally agree. I've had an 021 for a year or so and it's become my go to watch. I have been merciless with it, including body surfing with the Kids and clattering it on pebbles etc. Barely a mark. It's difficult to explain why it feels so good to wear, and also it needs some user time on the wrist to fully enjoy it - first feeling is wow its heavy, but that dissappear quickly. The micro adjust is great for hot days and cold days as my wrist swells up. I like its quiet and unassuming looks. But most of all I like the feeling of total quality it gives the wearer. I have much more expensive watches that don't feel this special to wear. I'd urge anyone thinking to try one on - definitely wear smaller than the specs suggest. My SKX wears bigger.

Nice review, all around and great photography. Beautiful piece.

Thanks for a great review. I have the same watch and the dial is a beautiful colour.

Very nice in depth review! I like it how you broke down the different levels of finish, it's not often you see that. I've got a few Seiko divers but none in this price category and the MM 300 is a very attractive piece!

Awesome video

Hola amigo, me encantó la revisión que le hiciste al reloj, yo tengo el mismo reloj hace casi dos años y la verdad es que es un reloj impresionante, el reloj corre a +5 segundos con la esfera hacia arriba y +1 segundo con la corona hacia arriba, mucho mejor que algunos suizos de mi colección, mi meta a mediano plazo es tener un Grand Seiko Hi-Beat,.me encanta la marca Seiko, tengo el marinemaster, el sarb033, el pogue, y el sarb017. Estube evaluando bastante tiempo si comprarme el Seiko MarineMaster o el Tudor black bay Usado, al final me compré el marinemaster, me enamoró su caja monobloque realmente es única y también su calibre que es de una manufactura increíble, este reloj no tiene nada que envidiar a un reloj suizo de $5000, estoy muy contento con el reloj, Seiko no alardea con su precisión pero en este reloj es mucho mejor que un cosc, lo tengo ya casi dos años y es muy muy estable es su funcionamiento, un saludo amigo desde Chile, recién descubrí tu canal y es de mucha calidad, ojalá sigas teniendo más suscriptores.

I have the SKX Diverse as i also have two Seiko Samurai's my next will be the Seiko Marine Master ! Very well done review.

Oh yes, I totaly agree with you, it´s the best diver you can get for the money! I have my one for a month and it becomes a part of my body after 10 minutes and it won´t change till today! I look my whole live for a diver, then some month ago I saw this beauty and fell in love. Now I know, what I´ve been looking for so many years! Please go on with your videos, thank you for that!

Nice!

its on my list to take it!the best seiko diver ever!

love the review. Try using blu tack to clean the dust off your watches before filming. It will look much more pro

Great work! what do you think of the copies from Heimdallr? I've had another version, and at the price they are mindblowing...

Is it worth buying seiko marinemaster in comparison to tudor pelagos and omega seamaster?what about build quality of the seiko?any issues while using the watch?what about build quality of the watch?any special maintenance needed for the watch?

do you have problem with triangle lume area?mine come with issuses

The end game seiko. I think it's actually pretty cheap for its value.

+5 seconds a day? thats rough, my SLA023J1 is running at +2 in real world use

That's a cool Rollei 35.

If only they'd update the quality of the indicies which is the only weak spot on the watch in terms of quality

No I don’t know “that feeling” 😂😂😂

Its way too tall. The new SLA055 should be released in black and blue with a bracelet. I would buy that. My two MM200s are better fitting watches but with lesser movements So basically my seamaster 300 and sub date are still the best to me.

Seiko, make this in 41mm, 48 lug to lug, 12mm thick. Winner.

Its a Seiko dive watch that looks like every other Seiko dive watch. Too expensive too average.

Automatics are a pain
