Restoration: Omega Seamaster 176.007 calibre 1040

IMG_6050Daniel sent this one in, and said that “the watch was dropped in water and the movement has rusted”. Not what I really want to hear 😉

But not only is the movement rusted – somebody had broken off screws, and taken out parts and screws.

This watch will need some serious work and lots of spare parts…IMG_6112One day, I will learn not to accept watches like this one for repair 😉IMG_6123

The dial and hands are in good condition.IMG_6126

And the bottom plate doesn’t look too bad, but there might be more surprises below.IMG_6128

So far, so good.IMG_6134

Some corrosion here as well.IMG_6135

More corrosion …IMG_6136

… oh dear …IMG_6137

The date quick-set mechanism has seen better days.

IMG_6140

And so has the reset pusher.IMG_6142

The setting lever spring is rusted off.IMG_6149

And here comes the real damage – not much of this is reusable.IMG_6461

We manage to find an incomplete and taken apart parts movement on eBay.IMG_6468

The original movement in the two tubs on the left, and the parts movement in the two tubs on the right.IMG_6469

I start off with a new mainspring which I put into the donor barrel.IMG_6470

The gear train on the main plate.IMG_6471

The winding mechanism needs some serious attention.IMG_6499

After some acid treatment, I have at least some bits that I can re-use.IMG_6693

The first batch of new parts arrived – but we will need quite a bit more than that.IMG_6696

I can now put the base movement back together to see how that’s performing before going any further.IMG_6697

The wheel train is in.IMG_6699

Good to have an extra set of parts to chose from!IMG_6700

The winding and setting gears go in.IMG_6800

That’s not bad at all.IMG_6803

Now I can start on the chronograph layer.IMG_6966

Again, lots of new parts are needed.IMG_6967

You can see the new friction spring for the chronograph runner in the middle with the green anti-friction coating on the tines.IMG_6968

I put the auto winder differential and reverser wheel in, but I can’t wind the watch freely. There is too much resistance.IMG_6970

The culprits are the differential …IMG_6971

… and the reverser wheel.IMG_7030

I order them new, but the satellite wheel of the new differential is rusted onto the plate, so it doesn’t move at all! I make a return for the part, and get a new one back that works.IMG_7031

Here is the differential with the satellite wheel visible.IMG_7147

Finally, automatic and manual winding works.IMG_7150

Now it’s time for the minute recorder on the bottom plate.IMG_7154

This movement has a vertical clutch for the minute recorder.IMG_7156

The quick-set mechanism with new and cleaned-up old parts.IMG_7157

The clutch is in place.IMG_7158

IMG_7171

And the bottom plate is finished.IMG_7172

The dial and hands go on, but I notice some white paint missing from the minute hand.IMG_7173

So it’s back to the hand clinic.IMG_7174

The pushers are removed from the case.IMG_7175

The hands looking a lot better now, too.IMG_7176

Clean pushers ready to go back into the case.IMG_7177

Ready for the movement.IMG_7178

The movement before casing.IMG_7179

Look at all the empty parts containers …IMG_7180

The movement is cased.IMG_7181

And the rotor goes on.IMG_7182

I notice that the minute hand resets together with the minute recorder, so the clutch doesn’t separate well enough. I swap it over with the one from the parts movement.IMG_7184

Now all is well, and the bezel ring and crystal can go on.IMG_7185

That looks very nice indeed.IMG_7186

Just a new case back gasket to go, and we are done.IMG_7187

 

 

The case back is on, and an epic job is done.

So, in total, we used a parts movement for £270, and the following parts:

click 320-1104 £20
crown wheel 1040-1101 £52
reduction gear 1040-1432 £35
driving gear for ratchet wheel 1040-1437 £35
blocking lever spring 860-1733 £12
stem bolt for second hammer 1040-1759 £17
setting wheel 1040-1152 £11
winding stem £11
blocking lever 860-1726 + blocking lever yoke 860-1818 together £50 on eBay
spring for bolt-stem for second hammer £21 on eBay
friction spring for chrono runner 1040-1735 £28
wig-wag setting wheel spring £12
differential 1040-1475 £69
reverser wheel 1040-1464 £103
setting lever 1040-1109 £35
screw 2357 £8
screw 2480 £8
crystal £26
case back gasket £13

Not a cheap job, as my labour comes on top of that, but still well worthwhile for this watch.

  1. Hi, amazing work bring the watch back to life.
    I have been given one of these watches and it is very special to me. It is in very good original working condition apart from the strap.
    I have a few of questions to ask if you don’t mind?
    1. Mine has the same flat ended hour and minute hands, many I have seen have pointed hour and minute hands. Is this a rare feature for the ST176?
    2. The paperwork for mine also states model is ST1760007 is this correct or is it ST176.007?
    3. Do you have an original stainless strap for one of these watches? Currently mine has a Geckota strap and I want to find an Omega one to fit. There are some 22mm ones online but no idea they will fit. I think the original is a 3 bar strap with ends which should fit the slight curve of the case.
    I plan to keep the watch due to its sentimental value.
    If you can help with any info I would be grateful?
    Regards, Paul V

  2. Hey!
    Hope you don’t mind me bumping an old post. First of all, great job, as always. Second – the question 🙂 How do you replace the pusher gaskets? As far as I can figure out, they sit behind a “washer” of some sort. Is this supposed to be removed prior to fitting? If so, how do you do it and how do you put it back?
    Thanks and sorry for the many questions :))

  3. Hi, Christian. I see that you were able to find a replacement Omega crystal for this watch. I recently purchased one of these Seamasters but the crystal is an off-brand acrylic model that has some scratches. I’d like to replace it but having trouble finding one. Can you tell me where you ordered yours from?

  4. Hello
    Great explanation and work. May I ask how you did remove the glass : from the top or after removing the movement ? Mine is broken on the bottom side and I am trying to find a spare one for this 176.007 version without omega sign in the middle. May I kindly where you purchased it from ?
    Many thanks in advance

    • The crystal is pressed out from the inside out. You won’t find a generic crystal that fits with the bezel ring – only the Omega original crystal will fit.

  5. An amazing work indeed! Could you please Write the Reference Numbers for the crystal and the Tachymeter Ring and where you bought it from.

  6. Excellent presentation…as a novice restorer I am curious did you refinish both hands?
    If so could you do a presentation on just hand refinishing? I have tried for many years experimenting with different techniques. Some success. Thanks

    • The hands on this particular watch were replaced with new ones, but we restore a lot of hands as well. We will put up a post on hand restoration in the near future.

  7. Even those of us who possess no particular talents in tasks mechanical can appreciate the skills–and patience–of those who do. Thanks for this site and congratulations on another watch resurrected.

    Though some might argue that the expense involved wasn’t worth it in purely practical terms–I suspect none of your readers/fans would fall into that category, mind you–I am reminded of another pair of mechanics and their advice. I’m speaking of Tom and Ray Magliozzi (Tom is now deceased), better known as Click and Clack, the Tappet Brothers, who gave car advice to callers on their show “Car Talk.” Whenever a caller asked how much a major repair would cost and was stunned at their response, the brothers would ask the caller to consider how much a new car would cost Instead. Typically, the caller would then see the question in a new light. And doing the (car) repair rather than simply junking the thing would also serve, on however great or small a scale, to conserve our limited resources.

    Well done, and thanks again for your teaching.

    • Absolutely brilliant!!!!!! I have one of these….it was my 21st birthday present, so I have had it a long time. As a present to myself I decided to have it refurbished through a jeweller and watchmaker in Brigg and he sent it to the Omega factory is Switzerland to get done. It took a long time, some 3 months, but I got it back last Saturday looking fantastic complete with a complimentary (no such thing as a free lunch ) presentation box. The total cost including jewellers fees etc etc was £520 inc VAT. I didn’t have nearly as much done, but included glass, seals, wider, crown wheel, face work, hand work and push button work, but also its steel bracelet repair. These watches are not cheap and I thought it was damn good value. I will never sell this due to its sentimental worth to me and although I have a reasonably large collection of watches, over the last 40+ years my Omega is the only one I seem to wear……speaks for itself really.

  8. Amazing job – it’s great to see a ruined movement lovingly restored and returned to working order. Congratulations and well done to the owner as well for having the watc restored.

    Question is, how did the movement get so badly rusted? It must have been sitting in water for a while to get this badly corroded – normally you’d expect the owner to realise as soon as the crystal mists up.

  9. Worth every penny to get something meaningful working as intended. Great commentary as always C, fascinating to see how these beautiful little things work. Some sick mind to have designed it in the first place though! One day I will get one of your elusive repair slots, one day!

  10. As the owner of this watch I want to thank Christian for his perseverance. I had previously left the watch with two other watch repairers who both returned it as unrepairable – I’m now wondering if it was one of those who was responsible for the missing parts and broken screws.
    This watch had belonged to my best friend and was given to me by his widow so to have the watch working again and looking as good as new was well worth the expense and because the watch was a gift the cost of the repair is covered by it’s current value – not that I will ever sell it – it’s not left my wrist since getting it back!

  11. Christian, why a parts movement and 20 other parts? Were these no good on the parts movement and if so what was used from the parts movement?

    • The parts movement wasn’t complete, and some of the parts were damaged. We needed the bridge, barrel, click wheel, and lots of other parts from the parts movement, which was well worth the money.

  12. Cost is unrelated to worth – which is probably the only reason some of these old watches are still with us. Lots of work, but the result looks well worth the effort 😉

  13. What we have to remember is that even though it did cost a lot for repair….this watch will go on for years to come…..perhaps generations to come. It’s a stunning piece and looks as good as new 🙂 great job!!

    I’m still waiting to get my job to you guys. Sadly I missed out this time 🙁

    Best wishes

    Nick

  14. A great looking watch, its quite unusual and I haven’t seen one before. What a mammoth restoration job too, well done!

  15. Fascinating reading and great work! Good to see another 007 ready to re-enter service!
    Love the layout of the watch, and the 1040 movement is surely one of the finer automatic chronograph movements ever made (when they are not rusted that is).
    The central minute counter is a design feature I am very surprised not more companies have utilized. Nothing comes close to the readability!

  16. In fact not a restoration of one nice watch but of two. The donor also gets to live on – at least some of it. And perhaps the remaining parts of the donor will help restore other fine timepieces.

    Great and masterful work. Well done.

  17. Wow! What a job (read labour)! And equally, what a bill 😉 but for such a beautiful piece I think it’s well worth while 🙂
    How long was it exposed to water if you don’t mind me asking?
    Congratulations Mr owner and great work Christian

  18. Another amazing work! This watch is so beautiful and you resurrected it! You guys are amazing! 🙂 Congratulations Daniel!!
