I have a Unitas 498 pocket watch movement (see pictures) which has a shock absorption system I haven't encountered before and I want take out the setting safely so I can clean and lubricate it. I have tentatively identified the shock system as a Vibrax 160E. I have also included a picture of a close up of the system on the balance cock side. Anyone recognize it? What's the best way to take it out? I hope the pictures are clear enough. Thanks! Doug
