WD-40 and gaskets
Are the sealing gaskets (caseback, crown) negatively affected by contact with WD-40? This may sound like a looney-tunes idea to some, but i want to 'lube' and 'flush' the Jubilee bracelet on my DJ and also apply some WD-40 to the caseback to ward off corrosion. I know it'll make a mess. Watch is from the mid-eighties and the caseback gasket is new from when I bought it 2 years ago. So does this plan make sense, or.... ?

If you use anything use a silicone spray wd40 is a corrosive penetrant not advisable. Your watch is stainless steel it really doesn't need anything just wash and rinse every couple weeks. Rikki

Well, I see all of those cases (and lugs) posted here with the corrosion and pitted area where the caseback screws in which feeds into my paranoia, not to mention where people here talk about getting the cases repaired (built up).
I won't use WD-40 as your point is well taken re: WD-40 is a penetrant, so . |

Some gaskets don't fair to well with petroleum products

As far as I know, WD-40 is not, properly speaking, a lubricant. It is a "water displacement" solution. Credentialed tribologists and lubrication engineers may weigh in here.
Silicone may be what you need. Perhaps something specific for watch gasket applications. |

What causes case corrosion is a very acidic body chemistry which is not something you can readily fix. So washing is soap and water every other week should be sufficient. Rik

People use it for everything, but, you are correct. If memory serves me, WD, stands for Water Displacement, and 40 was how many tries until they got it right.

I assume you meant a corrosion penetrant since WD40 is not at all corrosive...

WD-40 penetrant oil, will swell rubber seals.

Maybe natural rubber but not the synthetics used in modern gaskets and O-rings...

there is a special lube that is used for gaskets. It's called Fomblin grease. It's the best of the best but it is not cheap. This is what rolex uses as well. It's about 50 bucks for a small container.. using anything else like the cheap lubricants like silicone are not meant for this type of application.. and WD40 is a NO NO.. fork out the cash for the right stuff or send it into rolex.. You will only make the crown and case gaskets worse by using other agents.

OK, dumb idea, then. I just washed my Datejust with soap and hot water for the first time ever (over 2 years). The results were nothing less than spectacular. The watch glistens like new one. So now I've incorporated a weekly regimen of washing it.

Approved secondary use is only done properly if a flame is placed in front of the spray nozzle at the moment one deploys the product, on spiders. |

I've seen wd 40 sprayed on clock movements that 6 months later were rusted and pitted.

Never use paint, it doesn't stay lit. Lysol on the other hand works great.

I'm not suggesting WD40 as a lubricant (it's really not one; it's a penetrant); I am just saying if you get WD40 on your Rolex it won't harm the seals.

It ultimately evaporates, leaving the metal unprotected, hence the rust.
