Todays victim, ain't she purtty.................................
I case you dont know the story, let me bring you up to speed. Long time ago I owned one of the first MM`s, back in 2002. At that time I had pulled off the bezel and had a look see at what there was. What I saw on the crystal retainer at that time made it perfectly clear it required a special wrench to gain access to the movement. So I never went any further in trying to open one. There were more then enough vintage watches to keep busy also,
Now, a few years has gone by and Seiko has changed how this baby is put together, and now I don't need no special stinking tool to get into them. This is a late model 2008 watch, where the change over date is (For the crystal retainer design) I do not know, but I know enough to know now that I`ll be able to get into all of them, I may need to make a wrench for the earlier ones, but thats part of the fun,
OK, So lets get to it,
Whenever I`m working on a watch such as this, she gets protected.................
The bezel pops off easily enough, not more trouble then a SKX diver.
So with that I can see the newer crystal retainer. You` notice I have tapped over the crystal also, and this is what I do on most case backs also before I remove them, I`v just found its too easy and really saves your hide if you slip,
It is not the inner set of lug notches that we need to put the removal tool on (They retain the crystal itself), but the outer set of notches that retain the entire crystal assembly and bolt it to the case just like a case back! Not only that, but the outer ring that comprises the case seal is "Left Hand" thread!! So by turning "Right", it unscrews as easily and as simply as any other case back should,
Previously, I had seen two small flats, and no outer notches on the earlier watches,
Here is a shot of the hold over lands for the earlier wrench, there are two lands like this directly opposite of each other.
OK, crystal ring is out, very far out looking sitting by itself.......................
And turned over. The flats or lands for the earlier wrench are more noticable here.
And this next picture will show you how it bolts down on a standard O-ring gasket in a channel, just like a case back.
I`ll say, the machine work here is absolutely phenomenal. Everything is beyond just being stately and workman like here in this machining , its more polished and perfect! The tolerances and polish and attention to detail here are much closer then you would find in a "everyday" Seiko. This case IS, a WORK OF ART!
And heres our stem release, right at 3 O`clock.
Removing the dial trim ring, it simply lifts off at this stage, gives a little more room to work the steam release......................................
And so that gives us a look at the Marine Masters crown and tube.
OK, I hate to say this, but this crown is anemic. This is no better crown then you will find on a Sumo or even a monster. Its only using one gasket, appears to be the same gasket used on the SKX!! Really sad about this. I would have thought Seiko would use at least two or three gaskets in this, but there is only the one! One stinking gasket!! No back up, its not even large by any stretch of the word. Ohh well. Lets put a trip lock on it! LOLLOLOLOL.
A few more shots of the crown.
Lets move on. To the empty case. In this case, the machine work still impress`s!
There is a thin rubber o-ring at the very bottom of the well you can see. This works as the case spring, butting up against the movement holder and taking up (gently) any slack in the over all height of the internal parts . When you are re-assembling the movement in the case, you have to be very careful not to let this o-ring get up under the movement, or it will interfere with the winding rotor being able to spin.
And now the movement as she sits removed from the case........
And now the back side, always the prettiest part,

And thats about it for now. You`ve been inside the Marine Master now!
I am hoping that in the future I can go inside the 8L35 movement also, These are going to need to be serviced at some point.
