Hey guys

So my Dad has owned the watch in question from new. He is a very practical man and from the 'use it 'till it dies' camp! 😁 I can imagine this 1970's Omega Constellation has seen decades of mixing up cement, carpentry, drilling holes in walls and working on cars... with zero mercy!

Its one of the few material items I've known him to become attached too, in fact the only one I can think of actually. Its in incredibly poor shape and in need of some serious love, it has spent the last decade or so feeling sorry for itself in the back of a cupboard. Having some time on my hands of late I offered to do an exterior restoration for him.

The watch has NEVER been serviced 😲 yet still works. Once the exterior is done we will be sending it off for a movement service. I really don't fancy getting involved in that house of horrors on a watch so dear to him. If it was a Seiko 7s26 with cheap and easily available parts.... I'd be in. As things stand and with the predicted mess that movement will be in.... I'm out!

As you will see by the end of this thread the work is almost finished. I need your help with part numbers for a new crystal and 1x spare bracelet link please guys.

On with the show:

BEFORE:

AFTER:



First obvious issue -
non genuine clasp hinge has been bodged in due to failure of the original at some time over the years. As you can see its bent and it doesn't fit the bracelet well at all:



On with the strip down:



Always a good sign when the very first thing you touch turns to dust ::facepalm1::



Not a problem, I have many new spares



I wasn't sure if these screws would come out! The one head I could see looked a bit iffy and they were absolutely caked in muck, but they came out fine with some patience.



Lets get rid of that nasty aftermarket clasp hinge:



Time for some much needed ultra sonic cleaning 🤮



First clean complete, ready for sanding and polishing to remove scratches:



Notice this is bent. Gently moved back into position with some light heat and pliers:



On with the sanding! I started with 1000 grit dry, moved onto 1200 wet and finished up in 3000 grit trizac wet. All done by hand, it took hours! Around 5 in total. Why sand? Why not just hit it with the polishing wheel? Sanding carefully is far more controllable and sympathetic as far as material removal is concerned. I did not want to lose any of the many shapes and lines. You can spot a watch that's had the life polished out of it a mile off, I wanted this to remain looking 'crisp'.



Polishing time:


Moving onto the watch head:



Light clean for the exterior of the movement With some Rodico and that's it. I do not want to disturb it at all, its a miracle it still works after all thee abuse and neglect. Safely stored away behind the telly under a glass for the time being:



Old perspex Crystal is toast! Does anyone know the correct part number please?:

Opps, a bit of a picture mix up at the end there! think of it as a small preview 😁

Ok, ultra sonic cleaning of the watch body and screws:



Sanding:



Note how crisp the lines remain, this would be lost if you just hit it hard with polishing.

Polished and ultra sonically cleaned (again) to remove polish residue:



Basic re-assembly started, more of a mock up really:

Lookin good and hopefully the movement will shape up economically as well. That is quite a restoration project you got there but you are on the home stretch now 😀

Isn’t a Constellation 168.0059 supposed to be brushed instead of polished ?

A genuine catch hinge came up o ebay nice and cheap. Not having the original I had to take a punt on it. It 'looked' like it would fit 😕 But of course, it was too wide by about 1.6mm in total. Everything else looked good and fitted well, so I thought I'd see if I could make it fit 😜 Doing this will get the watch usable and the correct one can be sourced at our leisure in the future if needs be.



A lot of sanding and grinding later:



Polished:



BEFORE:



AFTER:



So thats progress to date! Remaining:

New Crystal
1x spare bracelet link
Movement service.

if any one can help with the first two items, please send me a message or reply here. Thanks.

Its not I'm afraid, close but no cigar. If anyone does know what model it is please let me know. I dont want to open up the case back to find out! its gonna be a scary place inside there.

This watch when I received it has no signs of ever being a brushed finish, but that doesn't mean it left the factory that way I guess! I did ask my father what he would prefer and he said polished, I can do both. If he changes his mind in the future or damages it again I will happily brush finish it for him. I'm off to google the model number you just posted 😀

I don't I'm afraid no, I would really prefer not to remove the case back to find out. But if needs must I guess I will have too.
Surely your watchmaker can supply a crystal.

Sadly independent watch makers are few and far between, there are none local to me only big high street stores that have to send everything away.

Lookin good and hopefully the movement will shape up economically as well. That is quite a restoration project you got there but you are on the home stretch now 😀

thanks buddy 😀

PN2105 may work for the crystal

That was a great help thank you!

So my digital Vernier caliper is broken. The manual measurement is sketchy as hell (eBay caliper).

I've found a seller on eBay listing an aftermarket part as a pn2105 equivalent, rather handy he shows measurements.

Best I can see, pn2105 is the correct part. Thank you

Going to order it from cousins and cross my fingers

This is why I use an actual vernier caliper. Yes, I need a loupe to read it but no electronics, no sloppy dial gearing... just steel that ain't going anywhere. Fowler makes a good one. Starrett too. Might be a Japanese brand worth buying. Don't know what kind of tools you have available to you....

Those fume dials are so subtle and stunning.

Not to be a pain, but if it's never been serviced, you need a full movement strip down and servicing as well. The oils will have dried out long ago, and any wearing/running it will exacerbate damage to the movement. Sure it "runs" but it's not good for it. You've done nice work on restoring it for your dad otherwise, but the movement really does need attention too unless he's not going to wear it.

You speaketh the truth! No doubt. 😀

For my day job a digital one is fine, I have a decent one at work, rubbish one in my home kit.

My watch making tools are nice hobbyist grade, nothing special. Should I get more involved in my hobby I will definitely add a good quality manual Vernier to my kit amongst many other toys! Like a decent crystal press, the one I have is a liability 😵‍💫

Not being a pain 😀 this has been the plan since we started this adventure. It's about 40 years overdue! Clearly it's been around water looking at the rusty pins, and in serious need of a professional full strip down. It shall be done 😀 I will keep the thread updated.

I am not worthy. Blown away by your efforts.
And here I thought I did a good restoration job on my 1039 bracelet in restoring the original finish. I too did it by hand sanding and you are right it takes hours.

Amazing job... cool watch too.

If you want to have some more fun, unless the original crystal is cracked it's salvageable, start with 320.
