[TECH] - SEIKO 8L35 Teardown - Is It ANY Good? 

Love it! Perfect content - good quality video and your explanations thru the video are perfect - I wouldnt take a word away - Congrats!!

I love your videos because you simply don't get to see anything close to them elsewhere, especially this 8L35A deconstruct.

I filed down a cheap screwdriver to remove the micro philips screw (one) on the dial side plate on the 7S26A. I bought quite a few sets,of screwdrivers in the search for one that would work.... they didn't lol so I made my own which worked fine. I'm just a hobbyist so the 7S26a and other like movements are fine and cheap to play with. The most complex Seiko I've worked on (I think) was a 5606 and by complex I mean it had too many pingers (springs that go jump) but I've done a few swiss ones, my favourite being a 1966 Omega Constellation which was beautiful to work on. I enjoyed this video, nice to hear an Aussie voice for a change. ⌚👍🇦🇺

Good day happy to see this video i ll watch it at night ,i have already seen a part of it nice work keep on it

Greatful there are honest watchmakers out there that knows their stuff and are open about Seiko's behaviour in this price range 😅

Wearing it in my SLA043 for a couple of months. Runs like a dream and what i particularly like about it that it is stable in every postion. +2 sec. per day. Greetings and thanks for the good review.

Awesome video! Thanks.

Thanks review,now i service Seiko marina master my self

Great common sense explanations on this movement. Cheers, John.

A really good looking movement 👍 good video

Thank you for this video! I am about to service my GS calibre 9S56. The movement is almost identical to the 8L35 movement. Except the dial side because of the GMT-function. I still have to make this specific 3-prong tool to properly remove the rotor. Some time ago I visited a watchmaker shop in Tokyo, Japan, and it was very interesting to see all the Seiko-tools they offered in their store. Except that little 3-prong rotor tool, of course! Upon asking the shopkeeper for that specific tool, I just got a typical Japanese gesture for 'no, I don't have that' as an answer.

Wow, the modern 8L35's look so much better than these older variants.

This is very interesting and you are esaustive: thanks for the informations! P.S. What do you think about Miyota 9000 calibers? Best regards, Massimo.

This is the original 8L35A since 2015 the newer version, the 8L35B is completely aesthetically pleasing night and day difference. The newer 8L35B looks spectacular.

Very good demonstration. In you opinion which is the reliable movement for Seiko automatic? Thanks

Fantastic video. I didn't see plastic parts in the date mecanism like have in the 7S and 4R. I'm right ?

I note that this video is three years old. I have my 8L35s serviced at the Seiko service centre in Bangkok, Thailand. A service and case polishing is a fraction of the price for a Swiss watch overhaul.

Lighting is great. Is that centre wheel hole jewelled? Ah watching when you removed the calendar side I can see why there is no jewel.

Nothing special Video but a verry special Watch movement that I see!

Good day, For my knowledge, kindly confirm if the 8L35 is same movement as the 9S55 ? If there is a difference, what it might be ? Because I read that the 8L35 is based in the 9S55 but I don't know what it means exactly. Thank you so much

How does it compare quality wise to more common movements in cheaper watches like the ETA 2824 / 2892 or the Seiko 6R15 / 6R35.

Fantastic content - this was great. I'm curious, is there a specific watch or brand you like because of the movement or build quality? I'd be interested to know.

Got a question for you. I have this same movement in my SLA042. I took a quick rinse in the shower and noticed the crown was unscrewed. I haven’t noticed any damage. How worried should I be?

Which movement would you prefer as a consumer? 8L35 or a Breitling ETA in superocean?

Hi Sir, did you manage to service the 8L35 movement successfully ? Or was it abandoned ?

Loved the video thanks for sharing. Watches with the 8l35 are at least $2,000 but you didn't seem impressed with the movement. What brand or specific watches do you like because of a nice movement or build quality?

Hey man, I don’t watch a lot of these types of videos anymore but I have been thinking about buying the Marinemaster 300 and found your video. What do you think? Are they worth it?

What do you think about the 8l55 the sla037 has ?

I live in Middle East and i have no seiko service center so it is scary to buy a seiko with high price tag, my eyes was for a seiko re issue using 6l35

My local watchmaker who has been open since the 60s and really specializes in Rolex would not even attempt to open my marine master 1000 with this movement. They sent it to Japan

So what do you think of the 8l35 movement in comparison to the 4r and 6r movements, is it worth the premium?

For the price range, this movement is a gem! Japanese Movements from Seiko are verry good.

is it possible to buy one of these movements, and if so where from?

how's this movement compare to ETA movement?

What do you think of the new Seiko movements such Hi beats with 80 hours power reserve and Spring drive with 5 days power reserve. What has Switzerland do movement wise lol 😆

How do you remove the movement from a seiko marinemaster 300 with the monocoque case? I want to regulate it because it's now running -13 seconds a day after a slight drop to the floor. Any info or links to a site would help. I can't find anything anywhere online.

Dumb question but will this movement fit inside a Seiko Presage?

Could anyone tell me is there very much difference between the L series seiko movements compared with the R series. Obviously there is a large price increase with the L series so what do you get for the extra money spent?

I have a 8L35 movement, needs overhaul servicing, May I know if you do servicing for this movement?

Hi, do you sell the rotor tool?

Thank you! Very interesting tear down. I unfamiliar with the function of the rocker with the 5 gears on the bottom. Is this a much fancier version of floating nylon gear used in the 7s26 to change the day and date?

So what do you do once its all apart? (I kid!)

What is difference in between 8L35A and 8l35B and 8L35C?????????????????

Would you be able to do a video on how to regulate this movement?

Can u service the SLA021? I am in melbourne

cool👍

the newer 8L35B us manufactured using MEMS and has better finish and overall quality is better

8l35b movement is pretty different from the 8l35a movement with regards to decoration.

When did Seiko start using the 8L35B??

I know the seiko 8L/9S55/65 variant is better than Rolex 3135, but how does this movement compare with Rolex’s newest 3235 or omega 8900?

"Completely unremarkable....." Timekeeping technology came from aliens; #REMARKABLE!

This is hillarious, just a ‘moan-a-thon’ from start to finish!

I'm confused is this a high end grand Seiko movement because I just brought the SLA047 thinking that 🤣

Very interesting construction Adrian but as you said, nothing special. Seems pretty straight forward. Thanks for sharing. John S

It doesn't need to go back to Japan. There are Seiko service centres in Australia.

I was going to buy the Seiko sla051 Willard but now I'm not so sure. I don't like the Idea of sending it back to Seiko for service. Is this movement better than an ETA 2824 movement?

I have a question. Since you said 6R35 is crap, and I want a Prospex Sumo Hulk that uses that movement, I'm wondering what exactly crap means? What do I, as an ordinary person, NOT get if I take that movement. That's a real question. It would help me a lot because in my life, I have to spend my entire salary to buy that watch. I want to buy a solid automatic, but even though I don't have a Rolex, I'd rather wear a battery-operated watch than buy a bad automatic. I'm a little scared of the word "crap" from the man who disassembles the 8L35 and tells us that there is nothing so special that it could not be serviced outside of Japan. Thank you! Can you recommend me some watch under 2000$? I would buy Longines Hydroconquest but it is a bit expensive for me. One more thing, ok, you buy watch becuse of precision and al that, but what's the worth of that if I just dont like the watch... So you need to fit in good movement, design and price. Not easy thing to do.

magic finger, hahaha that's what she needs.

So the 8L35 is not really a 9s derivative? Everyone make it look like the 8L is a superb movement

They're probably really insistent on getting it to service centers because it's more or less a GS movement eithout decor. Still doesn't make sense why they won't let independants do it though

There are far better options with eta2892-a2 based movements. Or get a watch with chronometer grade conventional movement like sw200-1 or sw300 instead of overpriced Seiko SLA. Availability of parts is a major problem, that's why i stick with Swiss movements when it comes to service. I'll take 25 years old Breitling Superocean over brand new Seiko SLA.

I always read presumptions that 8L35 is an undecorated Grand Seiko movement. By seeing this video I can't think but that it is a pretty basic and very rough movement. Nothing special about it.

Seiko - nice watches, servicing at your peril.God help you if you blow a crown tube🤔

What I learned from this is that nothing here is special...

So this movement is what the Seiko Marine Master 300 has? Is it nothing special ? Typical? “Pretty boring “? Nothing special?? I thought this was made in house at Grand Seiko? Some of the reviews I read said that it’s basically an undecorated Grand Seiko movement. 🤔🧐🤔🧐

In short, nothing special at all. I wonder if any movement special at all?

"Nothing special" it's that all?

why are you crying about the phillips heads?

What a buzz! I take a car engine apart and ... it's trivial. Ferrari, Dacia, all internal combustion engines. I'm disappointed. Cogs everywhere, grease everywhere, what a disappointment. What? Is the Ferrari engine running better? No, no, it's trivial, even if you say the opposite. What? A Ferrari gearbox is not sold at Dacia? What the fuXX! What a buzz!

@Vintage Time Australia sir you just talked me out of buying Seiko Uemura SLA051
