D-5 okay for Crown seal?


Recommended Posts

I am finding that I have some resistance when pushing the crown back in to wind it closed on an ETA 2824-2. I think that the seal under the crown might be a little dry and that some oil might do the trick. Will a few drops of D-5 be suitable to put on the seal or is grease better...or something else? I seem to use D-5 as my goto magic all purpose oil :-) 

Cheers

Solution, I think, well seems to have resolved the issue was a little KT-22 around the thread and on the seal. 

 

As I suspected, D-5 didn't do much at all.

A silicone grease of some sort should be used. Oil could seep & contaminate.

Thank you for the info. I did wonder whether the oil would seep and contaminate.  It makes intuitive sense that grease is what should be applied to rubber seals/o-rings. I should have trusted my gut instinct I guess 

 

Thanks!

    • Haha. You're just in a wicked mood today John 😅
    • Heres my watch of today, a Smith 13'" RY . My missus bought me this for this Valentines day a bargain 14.99 with a reduction, the seller has occasional 20% off offers now and then so it was about 15ish with delivery. I love Smiths and i love bulleye dials, this is my first one. The watch arrived non working as stated and i knew what was inside and what would be against me, but i enjoy a challenge, we dont expect a lot if anything from pin pallet movements. A balance pivot was broken and i didnt have another staff but i did have another RY with a battered dial so i robbed the balance and tweaked it around to make it work apart from that mostly just a good clean and relubrication. Keyless works are pretty rough by design and the crown is a bugger to get in and out with the dial on, the setting lever hits the dial before it releases it, so a little mod is needed to help that along. Major problem was the pins on the lever were quite worn which make the old tg have a snow storm fit. Its a similar read for most pin pallets, these were brass as was the escape wheel. But perseverance is me, i didn't change the pins but i did spend some time dressing and polishing the worn areas which improved the trace a lot with some straightish lines 😅 and a beat error of .5 . Not sure what the lift angle should be on these and i Wasn't in the mood to work it out and who believes timegraphers anyway, but at the default 52° it runs with 260ish full 210 after 24 hours dial down , the verticals rates were pretty much all over place. So lets just put it in it's superlight aluminium case and see what happens. Been wearing it now for 3 weeks and it's consistently losing around 1.5  minutes a week winding each morning i think pretty good for an old pin pallet watch. I just love this dial, thanks wifey heres my Valentine's gift for yer sweetie x
    • I have a PDF below that will help. The problem was the PDF wasn't designed for this purpose it was designed to tell you what size watch you  have. Then it doesn't take into account movements come conceivably in different thicknesses.   watch-ligne-size-chart.pdf
    • That would be something! Which brings me back to;  
    • you think you're going to sleep tonight you're not, you're going to ponder the question of what makes you think those of the right parts?
