..because everyone likes visuals here- just off the bench-  Mimo AS cal 1130. It was an country auction house purchase nobody paid any attention. It took all of a day to fix up start to finish. I only needed to remove the gummy oil and the wrist Rauchkäse. My obligatory new mainspring though there was alloy inside. Hand rubbed the old crystal...

I was quite impressed with the movement and the case here. Hefty and the way the screwback slides open...high quality. 

...Is it from a military batch? No markings on the case back so dunno....and I don't know too much else other than prices for these things are all over the place. I paid less than 100 quid to get it to the states from UK. Imma wear it!

Do you know anything about the bar across the centre wheel? 

...not other than holds the movement in place, wedged between the movement and the case back like the internal case back of a Smiths W10...and suspect it might have something to do with the 'antimagnetic' claim. I saw similar Mimo where the bar is affixed to the plate with case screws but they were missing here and the ends of the bar sit in the screw holes quite solid. I'll mess with finding new case screws if it becomes an issue...

Lovely watch. Have a look here
 https://www.watchprosite.com/girard-perregaux/mimo-wwii-dienstuhr--a-closer-look/6.1004143.7068013/

Are there faint markings on the back? Could it be German military and the marks have been erased?

Looks like the radium is flaking

I looked hard with the microscope but couldn't see any sign of a a 'DxxxxH' stamping and given the original look of the case I don't think it was polished away...

...and yes - radium hands. Bad stuff and you can see the missing piece inside the crystal in the before photo. I take precautions but am not frightened of it, though I will pass on anything where its all turned to dust...

      Rolex 3130/3135 Automatic winding issue

      By clockboy · Posted

      There is a known fault with the 3135 which is if the watch has not been serviced the Auto rotor can wear. See attached pic.

      How do I check that?

      Vertex Dirty Dozen crystal

      By Michael1962 · Posted

      I sort of am expecting that ring to push against the rim of the crystal and possibly a seal against the front of the case. Hence everything comes out the back. Nothing else seems to make sense to me. I am trying to imagine why the crystal would not push out unless the ring needs to be backed off to allow the crystal to be pushed out, but then how does the ring come out? I am new to stripping watches though and am happy to stand corrected. 🙂

      Rolex 3130/3135 Automatic winding issue

      Hi @Roll1ex, welcome to the forum. It's considered good practice to introduce yourself to the forum in this thread: https://www.watchrepairtalk.com/forum/23-introduce-yourself-here/ But no worries. I don't have the spec sheet for the 15xx movements, but when I look at the 31xx information, it stands out that the endshake of the rotor should be between 0.01 and 0.03mm. That is LESS than the pallet fork and the lowest of all endshakes in the movement. Not exactly sure what you mean by that. The rotor itself is a unique part which doesn't have different heights. If you mean the height at which it is installed vis-a-vis the automatic bridge, then yes, that can be adjusted a bit via the two jewels that hold the rotor axle. Height differences vis-a-vis the bridge can also be caused by the strength with which the new axle is hammered/riveted into the rotor. And yes, that can be compensated a bit via the jewels.   This would probably indicate that the axle isn't perfectly perpendicular to the rotor. That could explain why the weight is closer to the rest of the movement at 9 o'clock -- it would then be furthest at 3 o'clock. That would be bad news. A new axle should then be installed... and properly this time.   As I wrote already, there is margin for adjustment via the jewels. As for the spring clip, the 15xx movements only seems to have one spring clip thickness (part 7911 - https://www.cousinsuk.com/PDF/categories/2878_Rolex 1530 Pages 6-10.pdf). The later 31xx movments have several versions with different thicknesses. But there is a good chance that the clip is worn (=thinner than it should) and should then be replaced.   But, in conclusion, if the rotor hits the caseback in one particular postion, then my first suspicion is that the axle wasn't punched in at a perfect 90° angle. That must first be re-done correctly. No other fixes will be solving that problem. Furthermore, if the rotor "dings" against the caseback when the watch is shaken (but not in other situations), then there is likely also an issue of endshake (more an issue of the jewels) or lateral play (more likely the sping clip).      PS: by whom? Independent or RSC?
