What I have a strong interest in is for the customer to be able to choose who they want to repair their watch. This means the brand would need to sell parts to the trade. Currently, they do not, which means that they could one day refuse to take the 8L series for repair, which ends the life of your watch. Also the conditions and repair timeframes may not be suitable for the owner of the watch, so their choice is significantly limited. I don't need the 8L series for my business at all, I have plenty of work. My concern is mostly for the people that have bought a watch which effectively has, an artificially limited lifespan due to the brand's business practices. Currently I do not take them due to the parts situation. To use an analogy, you've just bought a car, the car manufacturer does not sell parts to the trade and there's no aftermarket parts available. You are forced to always have that car serviced by the brand. One day, the brand decides to discontinue servicing that car. You now have a car which is no longer serviceable. The movement is well made and the finish is reasonably good. For the price you pay, the finish is appropriate. It's a well made, lever escapement movement. There's nothing magic or amazing about it. No "secret sauce" so to speak. Which is again part of my argument why their policy to refuse parts supply is stupid, because any decent watchmaker will have no problem servicing it. There's simply no need to send it to Japan. It just disadvantages the owner of the watch needlessly.

@hal0eight but no one said anything about any secret sauce... you should focus on the quality of the movt instead of the business proposition

That's easy, the entire calendar side interchanges, that's it.

It's a "FAVORITE" brand tool. Probably not made since the 1970's, so you have to buy used now.

Any airbrush style compressor should be OK. You need it to be able to provide about 6 BAR.

I charge a fixed rate for 3 hander and 3 hander chronometer, so it would be 3 hand chronometer rate if OEM parts were available. You do you, if you don't mind sending it to Japan every service cycle, then cool. My main point is what you get for your money. The marketing around these movements pushes them as something mythical, and they simply aren't. That aside, I have a real problem with OEM manufacturers trying to control your watch from the cradle to the grave. SEIKO isn't alone in this, several of the other big brands do it as well. It significantly reduces the freedom you have to do what you want with your property, for no other reason that straight up profits for the OEM. Some people know I'm part of the Right to repair movement and strongly believe you should be able to choose your repairer. Without technical information and parts available, the OEM can choose to kill your product at any time they like. It may be within 10 years, may be 20, who knows. Also, without the parts out there, the aftermarket will not be able to fix your watch when that happens. It's a very nasty problem waiting to happen. There will be no vintage scene for these watches.

Bracelet sucks. As it's a direct re-release of the 1960's watch, it's the same size. Dinner plate sized watches weren't in fashion back then as people wore them, all the time, so smaller was better,

It really depends where the trimmer is set to already. I don't remember which direction it is because I always do it on a Flashtest or QT-77. As the trimmer is so sensitive and just takes a whisker to change, I wouldn't try it without diagnostic equipment.

Up to you really. Just be aware it has to go back to SEIKO for service and they generally have a very long lead time, 9 months at present last I heard.

@@hal0eight Thanks review,now service Seiko marina master my self

No, casing spring.

Thanks, yeah I've never had an A or B here before, but have had dozens of C's through here and didn't check the tech sheets before making the video. I checked a few of my parts books for the crown and it does specify 55W12, which is a crown with a finer spline on it, domed "hat" and no SW. That said, a google image search does show some examples having the old SW crown, so it's a tough one to call. They have been known to change the appearance of parts over a production run. I think you are most likely correct though, that it is the finer spline part and this has been replaced at some stage.
