This is one of two Constellations Boris from Germany has sent in. I wanted to share this one, as the watch is in rare excellent condition.
It does need a service, as the amplitude is low.
First glance at the movement. No scratches, the screw heads have been used before, but carefully enough.
Spanish if I’m not mistaken 😉 Well, the little “E” gives it away if you are in any doubt.
Everything in almost as new condition!
I start off with a new mainspring.
The basic movement is back together and ticking.
Now it’s time for the bottom plate.
The date and day ring go back on, and I’m ready for the dial.
I case the movement without the auto winder.
Now the auto winder and oscillating weight go back on.
That looks nice!And that looks even nicer …
Omega Cal 751 – Train Wheel Bridge 1003
price?
No idea
I’ve done a good job of repairing you.
Can you tell me the ring part number of the date and date?
I had to replace it, but I couldn’t find it, so I left a question
Sorry, but that doesn’t quite scan. I guess Google translate isn’t as good as it should be. Best send me a photo with the part you need, and I’ll try to help you.
I sent an email “workshop@watchguy.co.uk” here.
I’d appreciate it if you could check it out.
We have this funny thing called “weekend” over here.
I received your reply well. But I am faced with difficulties because 751 rotor.
Is the 751 rotor compatible with 550?
and I need the pin part number to hold the rotor in the middle.
I always thank you for your kindness.
Hi Christian, I have one of these Connie’s with the same movement. It’s running great when hand wound but the automatic winding doesn’t seem to be maintaining the wind, so it just stops when I’m wearing it after about 48 hours. Any ideas what the problem could be?
Thanks
Hi Aaron,
Most likely either the reverser wheel or the rotor post bush.
Very beautiful work.
I am wondering if 168.019 (steel ring) can be replaced/modify to the WG verison to 168.029
Is it still possible to order the original crystal (omega logo) to this watch? Thank you.
I’m afraid I don’t know if that’s interchangeable. The crystals are now out of stock, so you will have to fit a generic one.
Thank you for your reply. I like to regulate the cal.751 (+8 ATM) by pushing the lever in the corresponding R direction, can this be done with a toothpick or a special tool is needed? Thank you.
A toothpick is fine.
Can you give me the size for the crown? I can easily get one from Cousins, I just have no idea which one would suit? I have just obtained a gold version of this watch, but with a badly worn crown. Any advice would be much appreciated.
The watch is of course back with the customer, so I can’t measure the crown. Measure it, and you will find a replacement on the Cousins website.
Great looking work!
What serial number watch crystal did you use on this watch?
I have a 168.029, and the replacement crystal for this watch is supposed to be the same fit. I am trying to find an Omega crystal WITHOUT the Date window for my watch – as I simply prefer the look of it.
Can you give me a part number? Or direct me to one?
Thanks!
Steel ring is PZ5118, gold ring is PX5118. Cousins UK has both of them in stock.
that is a beautiful watch..
Christian, do you post a blog for each watch you serve? or do you just choose to post some of them? I will sign up for the next service batch, my watch aren’t a special one. But to see all the step you do is one of the reason I want to send you my watch for a service.
if your answer is that you only post the more interested watches, would it be possible to get some pictures and a few words about the service on the “personal page” where a you can see how far long gone the service have proceed?
Hi David,
If I write a blog post or not, you will get a full set of photos of the service of your watch, that you can download and use however you like.
Best regards,
Christian
Thanks for the quick reply Christian, what’s nice to hear.
best regards David
Lovely 751. The last of the true great Omega classic movements (3/5/7xx series)!
The dial is also just fabulous.
C-shape case designed by Gerald Genta (if you do not know the name it is time to read up on one of the greatest names in watch design).
A true and timeless classic!
It’s a very similar shape to the case on my 2571 SeaStar that Christian serviced way back in August 2012, but which I cant seem to link to for some reason…
I know Tissot and Omega were merged in the 30s, but don’t know where they were at in the 70s when the SeaStar was made – maybe its shape is due to their common heritage, or maybe Tissot were actively copying Omega at that point. Or maybe it is just a “case” of convergent evolution 😉
Tissot and Omega was under the same umbrella (SSIH) from 1930 until the Swatch Group took over. They are still together.
The C-shape case was designed by Genta back in the 1960s. He made designs for Omega, Universal Geneve, Audemars Piguet, Patek Philipe and several others.
I have C-shaped watches from Omega and Zenith. “Old School” collectors are sometimes skeptical to the shape, but I believe this is changing with a younger generation of collectors.
That is a good-looking movement… indeed a good looking watch!
The winding ratchet wheel – I am intrigued as to how and why the screw holding it in place is eccentric… how does it rotate?
It’s a plate that is screwed onto the barrel bridge, and that itself doesn’t turn. Only the wheel around the eccentric plate turns.
Ahhhh… I see it now 😉
