Hi Rolex Experts,
i wanted to check and ask for your comments on the following:
I got a ETA 2789-1 movement serviced locally and not too long ago..Whilst I was doing some mods on my Snowflake recently, upon removal of the crown, I noticed that there was some dark-looking oil on the stem..
I dismissed it thinking that it was most probably lubricant from the movement and cleaned up the stem..just yesterday being curious, i removed the crown again and noticed that the same dark-looking oil was covering parts of the stem..
Is this normal, especially after the movement has been serviced?
If not, what should I see or not see?
Appreciate your advice..
Thanks!
