Omega Speedmaster Iv, Or 4,5 As Some Say..!

Recommended Posts

Greetings to you all from the north of sweden!!


Here you have another watch fanatic, and I don't want to miss this opportunity and introduce myself to the forum.

Daniel is the name and I'm not a watchrepair man by trade, just an advanced nerd so far.. :geek: ..!

I've just finished a service on an old front-mounted Cimier military watch with very good results.

My ambition is that one day being able to service my latest addition to the small collection... My "new" Omega

176.0012 Speedmaster IV, or 4,5 as some people call them. This is a 40th year present which I have treated myself with. 

According to the serial, 39xxxxxx, the watch is exactly as old as me, manufactured in the year 1975. This makes

it a really early one. The timepiece is in fantastic condition, original glass with no chips and almost no dents on the  

casing whatsoever. The case is really nice refurbished with the classic sundial pattern and the polished corners and so on. 

I've fitted a new stem with the "real" crown (st 43238) and have also bought the right omega bracelet(1162-172)

for this watch. I'm also very proud to have the original 70s box, very hard to come by in this good condition. The original

insert for the box is missing though, so a pillow will have to suffice for the moment. But as you can see in the pictures,

the original bracelet is only mounted where it sits in the box. The bracelet which I have fitted now is a really nice, thick,

sturdy and heavy bracelet which I found on a website.  I understand why they have a thicker bracelet on the new retromodel

of the mark II. A thicker bracelet really completes the the bulky 70s style casing and really gives the omega a great

prescence on your wrist. As you can see my bracelet also has tapered links and polished sides that lines perfectly with

the style on the case. The purist in me just wishes that it was an original omega bracelet... Anyway, this is me and my new

best friend...


Many thanks to Mark for your absolutely great videos, they really inspire me for my future projects. And ofcourse this already great forum,

you've started something really good here, keep it up! :woohoo-jumping-smiley-emoticon:

(PS: maybe a service video on the lemania 5100/omega 1045 is something for the future..;-)  ) :judge:


Cheers to all of you other nerds in here! :thumbsu:

Hej Daniel!

You've had good luck, or shown excellent judgement, in joining this forum. Great, down to earth members and excellent videos and guidance from Mark and the Mods. (Okay you oldies, who remembers 'March of the Mods'?)

I like your Speedmaster and your enthusiasm. I'm more of a dress watch man though, as befits my age.

Välkommen ombord

Well hi there rogart63!

Thanks for the comments. I really love the seventies style on many cases. but I'm not equally big fan of the seventies bracelets. 

At least not for many of the big 70s cases anyway. i think most of them are to thin to fit the watch properly.

But as always, exeptions do exist of course. As I said the purist in me would love to have an original omega bracelet, just like

the one on the new retro omega mark II. But the price is just to high on those, so this is a perfect substitute in my opinion.

But you know how it is, the taste varies from person to person...! :thumbsu:

Watch of the day at work...

My Citizen Aqualand analog from the nineties. As the speedmaster, this is also in fantastic condition.

A little bit on the "bling" side with the two-tone gold highlights.. :money: .. But I think it's okey for an everyday watch.

It sits on a thick black pvd-bracelet from the same company as the one on the Omega. Really sturdy these bracelets..!

I haven't begun any advanced service of my citizen. The answer is no, I don't have access to old citizen movements I'm afraid. But you seem to have som really interesting projects going,

so thats why I'm asking. I really like all these projects in this forum, so much ingenuity in everyone. Yesterday I got really hooked in the tread "diy water pressure tester". That's something i

just gotta build for myself. A really nice thing to know that your watch at least is water resistant.. :thumbsu:

Two more everyday watches from the tiny collection.

First a Seiko sportura chrono. All titanium with sapphire crystal, alarm,

chrono and screw down Crown. A really nice and light watch that you

can wear 24/7. I think It's perfect with Titanium as a material for a watch

- never gets cold on your skin.. :camp:













The fossil watch were a tribute(or rip-off) of the early Frontier led watch(yes,to the right).

The fossil is from 2002 and i really like the design with the bracelet lines continuing over the case.

It is a bit small though but it really looks nice and clean on your wrist. The led's seem to have very 

different luminance in the pictures but it is hardly noticeble with your real eyes. 


But...I still rather

have an omega Tc-2 instead..!

Ok, I'll show you my CPR collection...to give it a name.  :)


I got a couple more in a different place so this was a quick on from my cell camera...forgive the quality and brevity, it is my pleasure to post it, I've just been soooo busy lately I barely have had time to even wear a DIFFERENT watch every day!

The first one had to have the bracelet rebuilt and no matter what I did, the severely scored "bezel" is still showing the marks of whatever hit it. There is a post somewhere where I asked for the proper drill bit to do the job. Those are solid Stainless Steel links! I didn't want to be changing too many batteries so the crowns are all the way out! Keep in mind that they were all non functional and in very bad shape cosmetically and mechanically. I wish I had the before pictures!






PS. I found on line my original purchase...the before:

Hi Joe,


Only once, being busy with...more (different) Seikos! :)  Those Bellmatics are good movements to work on though. They have a bar you push to unlock the button... That I remember!


I believe I have like 40 Seikos mechanicals/auto, kinetics and quartzs and some Citizens (No Bellmatics). Funny thing is they are all in a couple of boxes where I have to actually "work" to get at them. Therefore the 3 or 4 Citizens above are more available!  My next projects include a couple of kinetics and a bunch of eta 2846. I'll probably be looking for some cases for the eta in the near future...and I have to finish a couple of 6498's (lazy me!) I'll probably sell. I sometimes work on a number of the same movement, so I can learn them by heart and figure what is the most common failure. Again, this is only achieved with numbers...5 or 10 of the same. Since you get them used and from different places they will show their unique trend to failures. At least that's my train of thought.


As an aside, my friend at work wanted me to "build" him a Seiko, with a blue dial and a new NH36...I'm still thinking about it and looking for the right dial in the meantime. It could be a fun project but not very challenging! :)


In any case, I'm looking forward to your Bellmatic project report!

Excellent thought process! I wish I could afford to buy 5 or 10 bell-matics to learn them inside out--I've only been able to do that with two movements both of them pin pallets: BFG 158 31/7 and BFG 866. These two I can do with no hesitation. I've only worked on Ronda's 1223 type alarms which are very different than Seiko, but I'll take it slow and at least I know you are a good resource for Seiko insights! Thanks buddy.

Damn those watches cleaned up nicely!

Really good work there man. I really like the seiko chrono to the right. The blueish/black dial with the yellow hands look both sport and utility at the same time. Not forgetting the bulky bezel also.

The citizen next to the nice seiko would have been just as nice if it have had som markers/scale on the bezel. But still nice timepieces all of them..! :thumbsu:

Thank you, Daniel, I figured you would like the ones with scales on the bezel, me too! 


BTW, I couldn't find the twin to yours...it is hard work to get at it considering it is in the safe with the other watches...and the safe has all sort of stuff in front so it is even harder to get to it! A word of advise, never put a safe in a closet, it becomes a black hole! :)

He he, a safe in a closet.. :D  It sounds very interesting, a black hole you say.. Don't stray too far inside, you could end up in Narnia...! :lolu:


I don't have a safe to put my "trophy's" in. Actually I'm thinking about buying a wall-mounted glass cabinet for my watches, sunglasses and other gems. It would be really nice

to have every piece on display with great lighting and such. Speaking about piece....I'm a little bit anxious about the end of next week... Guess who's going to get back his

favourite timepiece after service on friday the 24th..? Yes ofcourse, the Omega is coming home to me again. The watchmaker said that I've brought it to him just in time. It

was rather filthy but he didn't need to chande anything, phew! I really wanted to have all the original parts inside so lucky me..!


I only have one picture that was taken during the service, in the strip down. It doesn't look clean att all, but I can safely say that It is very shiny now..!

And not so many plastic pieces in this picture by the way... :cool:

    • Hello forum, i have some things i would like to say today if thats ok. Being here is something of a sanctuary for me, talking about something that i love doing with folk that i have become fond of ( yes quite surprisingly under all that craziness and verbal brawn lays a soft heart of gold 🙂 ). I imagine that the same can be said by many of you , a certain number of us are here daily both learning and offering any advice that we are able to. Quoting our experiences both successful and failures for others to learn from. For me at the moment just making this post is a distraction from my current bubble but also from the world around me for various reasons.  Its a place not just for teaching and learning but to make others laugh and smile and be part of a community. I would even go so far as to say we are a team, supporting and encouraging each other when needed and when we are down, my own situation with my mum being a perfect example of everyone's kindness. Thats the soppy bit out of the way 🙂. So my mum has been moved to a brand new facility after making amazing progress with her speech and word recognition in hospital ( poor mum has had to suffer my company and my teaching to the full extent of her visiting hours barring one day off for me that my sister insisted upon ) her consultant calls my mum his medical miracle 🙂, and will be starting her intensive speech rehab today after her initial assessment. Things I've learned about having a stroke, and I'd really like everyone to take note of the causes and outcomes of having one. Please do your own research I am a joiner and not a doctor 🙂, i just want to make everyone aware and just get checked out if you notice anything in yourself that you are unsure about, any risk of having one can be reduced with either medical intervention or/and a change of lifestyle ( which would be my own preference in an attempt to limit my risk, something i have now noticed in myself ). I do know a few of you here have experience but this is what i have become aware of and how it has affected my mum and me. First i want to touch on the effects of a stroke, not only to the sufferer but to the whole family, we all know how dementia affects lives. A stroke effecting language is almost instant non aggressive dementia. Like being in a foreign country where you can no longer read, write or speak to someone without some form of very basic sign language gesturing ( when annoyed i think everyone understands the middle finger ). But a stroke can affect movement ( fortunately my mum is virtually unaffected with her mobility, the nurses can't believe she is 87 and just had a stroke, she's like bloody Supergran, in fact she is a great great grandmother to 2 toddlers ) . Improvement after a stroke carries on for years afterwards, but from what i understand and now believe after being with my mum almost every day since it happened for 7 hours a day, language rehab should be started as soon as possible when the patient is out of danger and physically able. The brain is ready and set to go and rewire itself soon after injury, in a similar ready state to young children ( when we say kids brains absorb information like a sponge, thats pretty much true in early stroke patients) After the first few weeks maybe a couple of months things start to slow down and lesser progression carries on for the years following . After a day she could manage only one word, which was my cue to get on her back and start pushing her progress. Day two i wanted to see how capable she was so i had her writing on a whiteboard ( it wasn't great tbh ) . Day 3 and until she left the hospital most time with her was spent on picture/word recognition on my laptop, picture books, some writing and teaching her to play cards again ( i refrained from gambling for real money, though i was tempted, as I'm  pretty good at poker , she has a few bob and i have space for another watchmakers lathe in my watchroom 🙂 ) Now i suppose i have to back off as the rehab place is fairly intense focused and visiting times are crap as they interfere with all the physio and rehab going on . So i only have 2 hours max a day with her sometimes only 1 if her grandkids want to visit, but she is in good hands and i know she will get as much help as she needs , and as difficult as it is to admit i probably need a bit of a break and distract myself. I'll end this post for now but i want to come back and talk about what caused this and hopefully remind some of you to think about how we live , what to do in the event of a stroke and how we can lower our risk. I'm not a pussy by any means and very little frightens me, but seeing this first hand has put the fear of god into me if i ever had to suffer the outcome of a stroke. My mum is a tough old cookie and i imagine i will be just as tough, but watching the frustration on her face when trying to communicate completely tore my heart into pieces.  Please dont let this happen to you, do everything you can to avoid it, I'll come back soon to talk more about as long as everyone is ok with it, take care for now x
    • The fact that you have witnessed coils of the hairspring clinging or sticking together explains why the watch is running so fast.  If you reduce the length of a hairspring, the watch will run faster. When hairspring coils stick or cling together, this effectively reduces the active length of the hairspring, so the watch runs fast.  As nevenbekriev has said, the most likely culprit here is oil or other contamination on the hairspring causing coils to stick together. Cleaning the hairspring as he describes will solve the problem. Occasionally the contamination causing the hairspring coils to stick can be very stubborn to remove, in which case I suggest ultrasonic cleaning in acetone, naphtha or a commercial watch cleaning solution. Magnetism can also cause coils of the hairspring to stick together, if the hairspring is made of an alloy that can be magnetised. Finally, your watch has what is called a pin pallet escapement. They are considered to be less refined, but quite rugged compared to a traditional Swiss lever escapement. They are quite forgiving. They do require lubrication, if you haven’t done so already, find instructions for lubrication of these escapements to get optimal performance from this watch. Hope this helps, Mark
    • Murks, In theory, yes. For example I have a Seiko dress watch (dress style case) with a 6309 movement in it which I would not take diving, similarly, I have a Seiko divers watch with the same movement in it (6309) which is a diving watch. The only difference is the case (and crown sealing system), the diving watch case is made for diving due to it's more robust seal system on the case and its a more rugged design. Seiko 6309 divers watch: Seiko 6309 dress watch:
    • I mean let's say a was to make a dives watch is this mean as long the case is a dives case and a fits the movement it should be ok and is this means any movement longs it fit the dives case?
    • Whether my post is pinned there or not, I agree the “Lubrication Techniques, Oils, Greases, Epilame Treatments” forum should have a pinned post explaining why automatic oilers aren’t good for beginners, and better suited to production and service environments where many of the same calibre are lubricated regularly.  There are so many other tools a beginner should buy before automatic oilers, and it’s so important to learn to oil properly by hand. So many beginners and hobbyists have no idea how to apply the right amount of oil to each pivot, and just put some oil (usually too much) in every designated location and call it good. Not through carelessness, but through not knowing any better.   Mark
