Having started out on the watch repair course and spent some time tinkering with a few starter projects (with some success), I am pondering whether to attempt to service one of my main watches, which just recently has not been running very well and seems to be lacking in the power reserve.

The watch is a Breitling Colt Chronograph Automatic (A 13035.1) with a Valjoux 7750 movement. Now, I can obviously download the service sheet and I have seen that Mark also has a service video online of this movement (or very similar). I find marks videos informative and easy to follow..... add that to the knowledge that I have the members of this forum to fall back on should my knowledge fail me and my confidence in undertaking this task is bolstered.

However, my concern is that if I bugger it up and have to concede defeat, would a pro be willing to take the watch in a disasembled state to repair it?

I am sure I could send it back to Breitling in a dissasembled state but no doubt the repair / re-build bill would be astronomical! ?

If you are comfortable working on automatics with date etc., then a 7750 isn't too hard. What is a big issue with Breitling is they fit the chrono hands so tightly that it's almost a given that they will deform when removed, and quite often the seconds hand will leave its pipe on the chrono runner pivot. Of course new Breitling hands are available only to authorized repair shops. So it becomes a matter of redressing the hands as well as can be, and refitting the pipe (sometimes it's easier to make a new one).

I absolutely recommend against beginners working on expensive watches, as too often that doesn't end well. 

Get a cheapest Chinese 7750 that one can find, once you can take it apart, clean, lubricate and have it running same or better than it came, then it will be time to move to an genuine and valuable piece.

Agree with Nickelsilver the issue with some Brietlings is the hands are really tight. The first one I serviced the pipe of centre stop-second hand detached. Getting a genuine replacement was expensive and also difficult to find. However the service was relatively simple you just have to be mythological in your approach. Rule of thumb for me is if not confident don,t.

Did Breitling exactly use a eta Movement or did they change anything? Then the rumor about the hands I've heard that there supposed to be replaced And I believe they come in a set. But that would only be if you're authorized to get Breitling parts which are not. I don't know if you can find a enough replacement generic hands out there in the world are not.

What would be interesting is to see who actually does work on Breitling watches. Then reach out to them and ask them if I played with my watch and give it to you in a bag would you put it back together for me and the answer is probably going to be no. Or it's going to be really really expensive. The problem professional watchmakers have would be the same problem you have and that's getting spare parts and if they can't get spare parts they have a likelihood of not wanting to repair.

I agree entirely with @jdm. Don't touch it until you are comfortable cleaning/lubricating a similar movement and getting it running as it should. Then do it two more times.

    • it would be nice to have the exact model of the watch the or a picture so we can see exactly what you're talking about. this is because the definition of Swiss watch could be a variety of things and it be helpful if we could see exactly the watch your dealing with then in professional watch repair at least some professionals they do pre-cleaned watches. In other words the hands and dial come off and the entire movement assembled goes through a cleaning machine sometimes I think a shorter bath perhaps so everything is nice and clean for disassembly makes it easier to look for problems. Then other professionals don't like pre-cleaning because it basically obliterates the scene of the crime. Especially when dealing with vintage watches where you're looking for metal filings and problems that may visually go away with cleaning. Then usually super sticky lubrication isn't really a problem for disassembly and typically shouldn't be a problem on a pallet fork bridge because there shouldn't be any lubrication on the bridge at all as you typically do not oil the pallet fork pivots.  
    • A few things you should find out before you can mske a decision of what to do. As Richard said, what is the crown and all of the crown components made of . Then also the stem .  The crown looks to have a steel washer that retains a gasket. So be careful with what chemicals you use to dissolve any stem adhesives or the use of heat. You might swell or melt the gasket unless you are prepared to change that also . The steel washer maybe reactive to alum. Something I've just used to dissolve a broken screw from a plate. First drilled out the centre of the screw with a 0.5mm carbide . Dipped only the section that held the broken screw in Rustins rust remover. This is 40 % phosphoric acid. 3 days and the screw remains were completely dissolved, no trace of steel in the brass threads. A black puddle left in the solution.
    • I suppose this will add to the confusion I have a roller jewel assortment. It lists out American pocket watches for Elgin 18 size and even 16 size it's a 50. But not all the various companies used 50-50 does seem to be common one company had a 51 and the smallest is 43. American parts are always interesting? Francis Elgin for mainsprings will tell you the thickness of the spring other companies will not even though the spring for the same number could come in a variety of thicknesses. But if we actually had the model number of your watch we would find it probably makes a reference that the roller jewel came in different dimensions. So overlook the parts book we find that? So it appears to be 18 and 16 size would be the same sort of the arson different catalog numbers and as I said we don't have your Mongol know which Log number were supposed to be using. Variety of materials garnered her sapphire single or double but zero mention about diameters. Then in a section of rollers in this case rollers with jewels we do get this down in the notes section Roller specifications but of course zero reference to the jewel size. I was really hoping the roller jewel assortment would give us sizes it doesn't really. But it does show a picture of how one particular roller jewel gauge is used  
    • Seems to still do it through my mobile data, I use an android phone almost exclusively, but I'll double check it. Thanks mark Strange, I'll try my laptop that utilities edge. I've been on site half hour since I got home, it hasn't done it yet. Thanks John
