Rolex Crown lubricant Fomblin UT18

[rdwiow]

Hi

I am new to this forum, but quite active with other watch forums, I look forward to participating here.

I have a question that hopefully somebody can help with. I have a 16610 and the crown thread and seal is rather dry, I did a google search on what I should use and it suggests Fomblin UT18. I can only find this in 100g tubes at a horrendous price! Is there an alternative or anywhere that will decant a smaller amount? I have used silicone grease in the past but it doesn't give the same smoothness.

Any help appreciated

Rob
