Gasket under acrylic crystals?

The larger one is a Gotham from the 50's that doesn't make any claim to be water proof or resistant unless the back has been refinished.  The second is a clarin that says water resistant.  Could it be back gaskets that got misplaced somehow?

I've serviced a Seiko 8306-8020 where there was a gasket sitting in a groove in the side wall in addition to acrylic crystal having a tension ring. It was also a front loader and the crown had internal o-ring and not in the stem as usual. It was one of those earlier Seikos that still boldly claimed to be water proof and not resistant.

So for the larger case the gasket only fits in the place shown in the picture. So possibly a spacing gasket?  Also I would like to send the case out to be replated and they recommend removing the crown tube and I can't tell if I can even do that with this case. The other one is clearly removable.

The gold one appears to have a removable bezel, which traps or carries the crystal seal?

ps. What place did you find that will re-plate them? I've asked a number of places advertising plating for jewellery etc., but none of those will do watch cases!

A friend of a friend does plating and is considering taking on external work if there's a demand for it?

I thought possibly they were all removable but as close as I can look at this it looks welded or soldered in place. I don't dare to try to press it or force it out in fear of destroying the case beyond repair.  

As for replateit they do also repair cases and prepare them for plating.  I've never used them so I'm not sure if that is an extra charge or all part of the cost of replating.

I doubt the tube is integral to the case, it would make the manufacturing process more difficult. Tubes are either screwed or friction fit. don't forget plating does not cover blemishes, just like paint, so prep work need to be carried out to get the case as defect free as possible. 

Richard do you think it's a screw down sleeve? I'll try to clean it up somewhat with the ultrasonic after work and see if that clears anything up.

After cleaning I found there is an insert in the tube itself.  So the tube is threaded to a certain depth for the insert.  I do believe the tube itself is soldered into the case so to remove that I would have to drill it out completely.  I've never seen that kind of set up before but I'm very new to tinkering with watches.

So I ended up refinishing the case myself.   I am pleased with the results although it would have been cheaper to send it to rePlateit. And they probably would have done an even better job than I can do.  I relumed the dial myself also as it was radium but I didn't do the best job.  As I am just using this watch myself it is good enough.  I may try the relume again at some point.  As a side note because I replated the case myself I was able to take the hardware from the old strap that was on it, replate them and make a new strap with some scraps of leather I had laying around.

      Adding a 'pin' to a regulator 'boot'

      By dnhb · Posted

      Apologies for going on about this issue, but I've seen instances in which the boot is not thus "closed" i.e. the top of the pin is not folded over. What determines which of the two pin designs should be used?

      I once spent HOURS with this...  But for me, it wasn't about the crown position (which I had pulled out as instructed), but that I used a pointy probe to depress the "button". That allowed me to push it down to far and dislodge the keyless works. If one uses a screwdriver that fits the enitre with of the slot (I believe it was the 1.2mm one), you are safe.      Lucky you!

      Shake to start

      The high beat error can be responsible for the balance not starting up by itself.  You should be able to adjust the beat error with the stud carrier here:   When you get the beat error below 1.0,or better to below 0.3, it should start up by itself. If not, you have a different problem.          This may indicate another problem. But first correct the beat error, wind fully (!), and check power reserve again.    Best of luck,  C

      @carlosdv there is a pdf with the operating instructions further up the thread. It looks to me that you put the crown in the right position for the relevant subdial, hold down the reset or start/stop and adjust with the crown.   Tom

      By carlosdv · Posted

      Hello Mediatech, yes the back can be opened with a case knife, it is not very hard to take off or put back on. I would also like to ask a question myself. In my case my Polaris is having issues adjusting the chronograph, the subdials do not seem to work. I place the crown in position 2 to try to adjust them and nothing happens, same thing in position 3 for both of them. Otherwise watch works fine, the main hand for the chronograph was adjusted and works well. I consulted an Omega dealer about a service and got quoted 650€, now my question is about the movement. I think the movement is based or is an ETA 251.262. It does not seem to be in production any more and was replaced by the ETA 251.264. Is there any chance a movement swap would be possible? What are your recommendations? Please keep in mind this watch would not be sold and I plan to keep it with me for a long time.
