I finaly managed to get a Connie to complement my Omega collection, it is a Gold Cap model from 1966 with a 561 movement.  I went against recommended practice of " get high definition pictures and ask to see the movement".  The pictures were not at all good, and the seller said that he had no means of opening the back.  I'm sure this put off a few folk, but luckily my offer was accepted and it turned out well.  I did know that the crown was incorrect when I bought it.  After a couple of small adjustments it is holding 0 to +2 seconds on the timegrapher. :)

 

Here are some pictures I've just taken.

A service should smooth out the graph a bit.

One thing. My info says lift angle is 49° but you have it at 52°.

 

Ooh goody, tech stuff!

 

I looked up lift angle and saw what it was in a good little video on YouTube  - 'Classic Watchmaking: How To Determine The Balance Lift Angle Of A Watch Movement '

 

From what I saw, the only way to change the lift angle would be to restrict the amplitude until the desired angle is reached. I think I understand how that is achieved but could anyone give a definitive answer please?

 

Thanks

John

Really nice Watch, I like the looks of those calibers and casings. You can't go wrong with a constellation..!

I once had a seamaster automatic from the same era. Gold filled with black dial and arrowhead indexes, a real stunner. Sold it about 8 years ago,

something I will regret for the rest of my Life.. :pulling-hair-out:

Nice watch Geo. Piepan?

Hi Roberto, It was advertised as a Pie Pan, but t's actually what Omega term a convex dial.

 

You are correct it does have a 49 degree lift angle and that is the setting I used for the one in the thread on servicing a 561.  I was working on another watch yesterday and too  be honest I simply forgot to set the Timegrapher to 49 degrees.  on an 18000 beat watch it doesn't appear to make much of a difference in the real world, it's still spot on time today.  here is a link to a discussion on another forum that is worth a read.

Thats a beauty Geo , nice find ,i'd always thought of them as pie pan so something else i've learnt today  :)

 

I can understand your confusion Andy because a pie pan looks so similar to mine. On a pie pan the area between the indices is flat, whereas the area between the indices on mine are convex although the style is the same.

Thanks Geo , so do Omega do a pie pan or are they all actually convex dials ?

Thanks for the info Gro very interesting, will keep my eyes peeled

If you're looking for one, it's a bit of a mine field. Do a lot of research that way you're not as likely to get your fingers burnt.

I sugest you start off by working your way through everything on this site, it's invaluable! :-

Geo you've got great taste. I love the Omegas from the 50's and 60's. In fact they were my very first watches in my collection watches before I got into all the other crazy watches of the 70's. I have many omegas but I will share these two with you so that I don't hijack your post! My 561 is a fantastic runner and the 504 is somewhat of a rarity with its arrow head markers and low production number. Enjoy the connie "convex" Pie-Pan and wear it well buddy!

      B-Dip residue?

      By KarlvonKoln · Posted

      One-dip or naphtha should be safe, but are you sure it isn't magnetized?  I would also check that.  Although, if that balance is from an Elgin 760 0r 761, I would think it would have a hairspring of non-magnetic alloy.

      Replacing armoured crystal in a front loading watch case…

      By Curare · Posted

      Hi John I just did a Seiko Lord-Matic a front loader without a split stem, I used a crystal lift to remove it, although I had to have it that tight I though I was going to break the lift before the crystal would budge. So I decided that the press would be a better option as I think crystals with tension rings resist a lot of compressing. I used a crystal press to repalce it and the bezel with no issues, obviuosly a different watch to the Omega. I just took my time and kept inspecting the installation progress bit by bit Regards CJ

      Replacing armoured crystal in a front loading watch case…

      By Zendoc · Posted

      Hello All, I’m replacing the crystal in an Omega Dynamic, # 165.039, which houses a cal 552, installed through the front of the case. The replacement Sterncreuz crystal is, like the original, with tension ring. I removed the crystal using a compressed air technique to pop it out.  (I have a crystal lift, but I’m always fearful of marking the crystal edges and so avoid using it as much as possible). Now to the replacement -  any tips on putting the crystal back in?  Am I obliged to using my dreaded crystal lift to complete the task, or how about a crystal press?  I’ve put lots of crystals in using a press, but never with the movement in the watch. The thought of using one with a front-loader makes me very nervous, with the fully assembled watch sitting under the press. How would more experienced folks proceed here? Any advice, gratefully received… John Down Under…

      No thats straight out of the watch as i found it the balance wheel is almost as bad. I've never seen so much material removed.
