Wondering whether anyone else had experienced this. I repaired a colleagues Rolex after she smashed it in a fall, serviced, refitted rotor and fitted new glass. The plastic seal that arrived with the Sternkreuzer glass was too thick so I refitted the old seal. Watch us running really well and has been on the wrist for a few weeks but large amounts of debriefs formed on the dial, hands and glass. In inspection it looks like small particles or shavings of plastic, I can only think this us coming from the refitted seal, any thoughts gratefully appreciated.
