Daytona sec@6


LeSentier

Recommended Posts

Guys,

Last week I had a long chat with Domi, regarding several new projects. One thing concerned the unreliable and already discussed Daytona sec@6 movements. Domi told me, that he could make the movement reliable, and since this an interesting point, I would like to support him.

He already modded a sec@6 movt with some parts of an AP sec@12 module, tested it and it worked flawless. The reason is, that he used parts and wheels from the AP movements and exchanged them with the parts of the daytona. He said, that some wheels of the AP are pivoted ( don't know if this the correct word), and they would make the movement reliable although the extra gears.

The problem is, that he has no picture available from the needed parts, and this is the point where I need your help:

Can anyone send me pictures of a dismantled AP module, where you can see the wheels and parts? I am in contact with Domi, and he can help to find out and name the parts that we need.

At the moment, he needs two AP modules, to build one reliable Daytona. I am willing to spend cash, but not buy two sec@12 APs to build one sec@6 movt. :bangin:

If we know the parts, we can try to source them and try to make one of the most desireable reps reliable.

If you have non working Daytonas which are in a great shape ( white dials with champagne subdials prefered) and you want to sell them, I am willing to buy them from you, and finance the project. I will also cover the costs of the needed parts ( I will wait for your pictures and Domis parts list) and will pay Domi to build us a sec@6 Daytona that works.

of course, this would not solve the case issue, but who cares? :whistling:

Would you support this project?

Cheers, J

Freddy, thank you! Of course I have read your graphite thread, and I think that Domi also tried the graphite treatment successfully. But: what if the requested parts could lead to a more reliable movement? I can only tell you what the essence of my chat with Domi was. And this was about the AP parts described above. You are much more specialist then me, so if you think that these mods won't do the trick, please tell me and I save my $$.

But if the wheels used in the AP are a solution, I would buy a dead sec@6, try to source the parts, let build a Daytona by Domi and write about the result on RWG.

All I need are the pics, and a Daytona

Every feedback is welcome

Cheers, J

I have no idea whether that will work. My point is that since the graphite works & is cheap, readily available & easy to implement (during a standard overhaul, which all rep movements should have), why opt for a more expensive unknown?

I respect your opinion, and as you just said in your graphite treatment thread, the first watch is still running. Perfect.

But why not give the exchange of some parts a try, since Domi is convinced that it works? I mean, some wheels cannot cost a house, and of course the watchsmith's labour and the watch itself. I think that sourcing the parts is the more challenging game. But there are also dealers and member that have access to the factories or to the parts, so I am not worried about that at this stage.

And I must say, I thought that there is more interest in this sec@6 theme. But the thread is young, and maybe someone is willing to send some pics, and then we need a source for the parts.

I think it is a good possibility to try it out - if it doesn't work, it's just my money that is burnt, and I can go on to the next project.

Best,J

Apart from those parts working or not working. I highly doubt that you can buy those parts separately from the rep factories. From experience I can tell you that most often they don't want to sell parts.

J,

I think that this sounds like a interesting solution, hope you can gather the parts and give it a try.

As far as the graphite treatment goes, Domis honest opinion is that its just throwing your money away. He performs it if you want but does not recommend spending your money on it.

Anyway, Domi is a very skilled watchmaker so it sounds promising.

ok, Domi just replied to my questions and sent me this pic - thanks to Francisco for his support on this!

We need 4 of the marked wheels including the bearing jewels ( rubies?)to build one Daytona.

The challenge is now, to source the parts. Does anybody have connections to the factories, or do you know who could give me support? If anyone has a clou or could source the parts, drop me a PM - I will pay a commission for it!

Thank you,

J

How much is the modding?

Have you ever heard the expression: "Putting the cart before the horse"? :lol:

Interesting project, I wish you the best of luck! Best bet it to email as many dealers as you can, not a complicated email explaining everything, just a simple one, requesting the pictured parts.....

Let me ask a question:

Why go to all the effort, when the rep A7750 case has such issues? Too thick, bezel slope is all wrong, etc.

I've spent quite a bit of time, money, effort and brain sweat on my reps--but I always started with a case that was near perfect. To me, the stuff inside the case can be fixed, but if the case itself is off then there's no point.

That's my line of reasoning anyway. I'd be curious to hear yours, if you want to share, why you've embarked on this project.

It's good stuff though, always interesting to see research and development being done!

This makes a lot of sense. The case does suck. I have a gen Daytona and a friend has a rep, the two are so totally different it's so easy to tell his is a fake. But on the other hand, the R&D is fantastic and quite intriguing! I think you are both correct. If we can start with the basics somehow, the case, correct the very obvious terrible flaws and then move our way into the remedying the movement issues we then can finally win the obstacle of having a beautiful accurate Daytona! Then when that happens and the factories can't make the reps fast enough, we all will take turns and go to China where they owe us a very nice dinner and drinks while we say, "I told you so!" Well maybe the last part will never happen but hopefully one day there will be an accurate daytona rep!

The key (you will need to research updated URLs as they have changed).

Freddy, don't you think the reliabilty of your Daytonas has something to do, that they are 1st gen?

Very definitely.

That said, I cannot vouch for others who may not have followed the procedure I used, but if any secs @6 Daytonas have failed after having been treated as described in my original tutorial, it is news to me. The 1st test watch, along with the 2 others I treated subsequently, have continued to run without incident.

There was a poll on another forum, the results proved the graphite treatment was not successful on multiple secs@6 watches, it was quite a large and long discussion/poll too.....

I was not aware of such a poll. Odd, that it was not posted here, since this is where the procedure itself was posted. Still, without knowing the background (whether the procedure I used was followed in those cases where it was 'unsuccessful'), I remain unconvinced that powdered graphite, applied as I did it, would fail in an otherwise properly serviced watch. But I appreciate the heads-up, MP.
