Origin of this midcase?

[ck5533]

Recently I've acquired a midcase 16610 T (M serial number) claimed to be Sean (etaswiss) from a member.

 

After cleaned inside & outside of the midcase, found;

1. the crown guard is in a different shape, btw gen crown is on M case.

2. Crown (tube not screw tight yet) sitting much lower compare to my other Sean's sub case (V serial number). I am worry that the crown will touch the bezel once installed.

2. The lugs are pointy rather than flat compare to V case.

3. if you can spot others

 

P/s: the one with insert is from V case.

 

If you have a Sean's M serial number 16610 T case, please tell me this is the correct profile.

 

Thank for looking.

The top case the M95xx is a Sean/ETA Swiss case. The M58xx is not a Sean/ETA Swiss case. Can tell by the finish and the serial number.

 

Cheers!

The top case reads V 9XXXXXX definitely from Sean, because I purchased it from Sean directly.

Now, the bottom one M58XX where is this from??

 

Will be a easy tell if I try to install a gen movement tonight..............

I can see where the crown on the M case is set too far into the case. Looks like it will interfere with the bezel assembly when installed.

I remember this being an issue with the WM9-V3 case, but crown position was higher on that case for a 2824-2/3135 movement. But I can't tell fr pic #2 that the crowns are at a different position- like you say, just that the cgs are shaped differently. If it fits a gen movement, it could be a WM9-V3.

You're right, after google WM9 on net, it looks exactly like mine. I still prefer Sean or TC case though, is the best out of the box.

It does take gen movement without mod. 

 

Which is more accurate comparing to gen, WM9 or Sean/TC??

That looks like the BK case. The little movement notch matches one i bought last year with same serial number

other than that, i wish someone could tell me how it compares to gen in term of accuracy.
