Servicing a white gold Daytona

Bas always a treat to read these type threads.

Yes, sort of.

I wonder what the RSC missed?

That sounds like it is either caused by too much or too little lubrication in the setting mechanism.

Thanks for the kind words everyone

It's just my job, and it is fun to share something else than ocd or investment threads

Thank you for sharing, Bas. I love these threads!

Agreed. Fascinating to see beneath the covers.

Thanks Bas

They both appear to have failed at the base of the threaded section which, looking at the photo, looks like the thinnest point.

Oh well !

[Oldfellow]

Really enjoyed this thread, a fine contribution, thanks for your effort.

[Muxi]

Thank you for the kind diagnosis Sir! It is much appreciated.

Great thread. Thank you!

Thank you Bas, really great and interesting

Stuff the majority of us never get to see

Are you always working under magnification to see everything?

Do you ever need to consult reference documents to remember how to tear down / rebuild certain movements?

[Flybak]

Super cool stuff Bas, thank you!

[KeithP]

Fantastic- thank you, Bas!

[nch209]

Over my head, but awesome all the same! Thanks for posting!

I'm quite new to the daytona, so yes I definitely use the Rolex technical documentation just in case, so that I do not forget a lubrication point or something like that.

I use my 4× loupe for most actions, then 10× and 25× for specific things like checking the wearing marks on parts or while lubricating the escapement.
Loupes are essential and I couldn't work without them, even though I still have good young eyes, it is just too small to properly see what you're doing.

Really interesting stuff

How many hours a day do you dedicate to working on these? I can imagine it must get quite taxing

Do you find it quite relaxing or are you typically working to very tight deadlines and it’s quite pressured?

Hi Bas

How long does it take to actually service a watch? By this I mean take it apart, clean the parts and reassemble it. I suspect that this takes a lot less hours than the weeks it is away at Rolex.

Thanks Bas great post , i am always amazed at how intricate movements are combined with the skill and engineering that goes into them in the first place , that's why we love mechanical watches , its certainly not to tell the time as there are much better options for that .

I'm responsible for the whole watch, so I do the movement and the polishing as well. A watch like this will take me a little more than 8 hours because I'm pretty new to this movement.

A DateJust with 3135 for example I can fully service in 5-6 hours including polishing.
Then it will need a few days of running to check if the automatic module works as it should, the accuracy is good, the power reserve, etc.

There's obviously a bit of pressure since you want to keep average lead time at 4-6 weeks, but too much stress and you will make mistakes and this you want to avoid at all cost.

Great post Bas. Please show the finished product, if you can. Cheers

[subtona]

Excellent stuff Bas. Thanks for sharing!!!

Have you ever reassembled and then found a screw and thought ‘hmmm, I wonder where this goes’

[Art 1]

Thanks!

Wait, I thought this would be worth much more after you've worked on it? Are you saying the investment value has now gone down?



Great work as always. Thanks for sharing. The 4130 is still my favorite Rolex caliber.

Hi Bas,

When there is a new/improved part design does Rolex provide the replacements for free, or does the customer have to pay for the part replacements (if they aren't part of a normal service cost)?

Thanks for sharing this with us Bas, always interesting. Looking forward to the updates tomorrow ;)

Any service has to be done on the vertical clutch ? A lot of press release and article talk about how reliable it is and how you can leave chronograph module running constantly without wear.

Thanks !

[Chiboy]

I always enjoy these threads, as well as Bas' reasoned and interesting perspective on things.

I find it interesting that very likely most of us on TRF wish we had the knowledge and tools to do this. It's different than repairing or maintaining even a Ferrari,* where a few readers can or do some stuff themselves, but here MANY, MANY folks are envious that you get to take apart, clean and fix and put back together these mechanical marvels.

* - I do not own a Ferrari; it's just an example of a car on the fun, exotic end of the auto spectrum

[soicanbefree]

Looking forward to seeing the before and after on the case / bezel.

I have always wondered how these bezels can be touched up.

Would love to see a side by side.

Thanks for doing these posts they are a true gem.

[inadeje]

Thanks OP - perfect thread.

[ikincooper]

Great post, love learning a little more about how our obsessions actual work. Thanks Bas
