Seiko 7S26 Watch Service. Movement Disassembly Tutorial (SKX)

This video is of the disassembly of a Seiko 7S26 movement as part of the watch service procedure. A very popular movement that is found in many Seiko watches and most notably the Seiko SKX. This was my first time inside one of these movements so I take you on my journey into the unknown! The aim of my channel is to try to inspire more people to try watch repair for themselves as a hobby.
I found the movement to be typically Seiko and well made although compared to the 70s Seikos I am used to these seem to have more nylon parts and thinner material. I guess this is progress for you.

If my videos have helped or inspired you into this hobby then I would be grateful if you could support the channel. A little goes a long way.


Thank you for your support.

I am going to service my one, will be my 1st venture into watch repairs. Bought all the tools and oils etc and watching this series diligently. What could possibly go wrong🤣

[SideWalkAstronomyNetherlands]

You sure made a lot of progress in only 4 years :) Better cameras etc too. :)

Brilliant job mate and thank you for working on it for me. Your videos really inspire me to try more myself .

You make it look so easy, I tried to rebuild a module from a Ulysee Nardin, it was a mess, and I had watchmakers all around me helping. You are talented

This was genuinely fascinating and interesting. Thanks for taking the time to explain all the various steps involved.

Nicely done, Mike. I enjoyed this very much as I am beginning my own journey as a watch tinkerer. You DO make it look easy and I hope with lots of practice I will have the confidence to dissemble and reassemble a movement without damaging it or losing any parts ;)

What a wonderful journey! thanks for the ride! I have my seiko movement but it's really old and for what i know, never had a service sadly.

Great video. It reminded me of the time a mate of mine who knows nothing about cars tried to check the water in his. He removed the oil cap and filled it to the top with water.

So cool.Just learned more here than I have collecting for the last 5 years!

I have a 7s26C about four years old, and the outer calendar works hold-down plate is quite different from yours. For one thing, it doesn't have that special screw that you had to modify a screwdriver to remove, just four regular slotted screws, which was nice.

Great video, thanks for taking the time to do it, cheers, Mark

Thanks Mike, great video. Seems daunting to put back all those parts in exactly the same positions again.

Super stuff mate, I'm learning heaps of valuable tips and info from your videos
Big Like👍

Subscribed! Thanks! Let’s do a Silita next!

Thank you Mike. I guess with all that oil, it did inhibit any corrosion from moisture……just trying to look on the bright side. Very nice work and very much enjoyed watching!

My dad was a WD40 man, but fortunately he confined his attentions to clocks. :-)

Many thanks for this, Mike. I have one which needs servicing but have taken the view that it's best put off for as long as possible. Doesn't look especially daunting now though, because there's such a strong Seiko family likeness. Judging by the video it does look like the standard of manufacture is more functional than in the earlier movements, but there's an elegant simplicity to the design especially of the calendar works which looks like an improvement. All very interesting and helpful.

Lol, can't sleep so binge watching your vids as I regulate a Komandirskie, it runs insanely fast and noticed not the fine adjustment arm but the main arm had been moved round like 60 degrees so took my good Amphibia out, looked at the angle of the main arm on that and rough set the Komandirskie's arm to roughly the same and the balance wheel is running a whole lot smoother but time will tell, set it to IAT at 0230am and will check it in 12 hours to guess how much its gained then if I can get my feeble brain in order I might be able to use the magic of maths to work out the angle fore or aft to bring it in to the area of the fine adjustment.

Hello ThE Real MB! Is that a glass of wine or Moebius back there?!?! BTW... this ViDeO is REALLY clear and bright. Well lit! Well done as usual.

I was waiting for this one. Cheers for showing.
