hi all, I have recently acquired a 1967 seamaster chronostop .watch runs great but I have noticed that the 865 movement is a little loose in the case.removing the back I found the movement clamps are tight .should this model have a dust cover over the movement?.would that being missing let the movement move .the spacer ring is in place.any help would be most appreciated,cheers..greasemonkey

 

The movement should be held in place by the case clamps which locate against the inside of the case, maybe these are not located correctly?

If you have a picture of it then it may help

 

No dust cover on any of the ones I have seen. Must be a matter of incorrect location of case clamps.

 

hi,thanks for your replies,please see photo in previous post.the movement clamps hold it tight to the brass outer spacer,its the spacer that moves.its seems as it needs something to take up the space between the back of the case and the movement.

 

Please see the picture below. Seems the clamps are missing all together on your watch (picture "borrowed" from the net).
You need two of parts: Case Clamp, Omega 865 1911.

 

thank you northernman,mystery solved.there are two clamps on my watch under those screws but the are bent at right angles and they fit in the cutouts in the movement ring.that confused me[ its not hard!]i did not realise that omega used two more to secure the assembly to the case. i will order some up.many thanks for all your help.great forum this,makes me fell guilty i dont post more but my knowledge is very limited,cheers..greasemonkey

 

Please not that these are not cheap.... About GBP5 each to watchmakers. "Street price" I do not know.

 

just bought a pack of 5 on ebay for £5.95 inc p+p thanks to you supplying the part no,so looks like i got lucky,thanks again..greasemonkey

 

The metal clamps should pass over the cut outs in the movement spacer and then push out in to the grooves in the case.If the clamps as too short or bent then they wouldnt touch the case.

 

hi ,thanks for that photo,i will wait for the ebay ones to arrive and see what kind of fit they are.cheers..greasemonkey

 

hi greasemonkey, where did you get these omega 865 clamps 1911.. Would u have any extras to spare, sell to me. Thanks.

 

There is an ebay seller selling a pack of 5 of the 865 1911 clamps for $20, thats a very reasonable price
