Well spotted! I guess it is an automatic bridle winder then. Should be pretty handy as I already have a set of normal mainspring winding arbors/handles, but this Eterna set has odd sizes included which my Bergeon set doesn't already have.

Thanks.

      Hiya watch people,  any more ideas on what to do here yet ? How about just adding ourselves to waggy's list for now. You dont have to add your full name and an email that can be trashed takes minutes to set up.

      Vertex Dirty Dozen crystal

      By Michael1962 · Posted

      Certainly looks like a ring that needs unscrewing in that photo. It definitely looks like a thread above the castellated ring as well. Separate to the caseback ring thread. It even looks to be a smaller diameter. I would expect that. Once undone out of its thread, it should fall out of the case. Would it be possible to make a tool shaped like a letter H with one side of the H engaging the castellations in the ring and the other side of the H for you to be able to unscrew it using your hand? Making a tool with 6 'legs' to pick up all of the castellations would be a labour of love.

      Can anyone advise how to remove the crystal from a Vertex DD case ?  I think I need to unscrew an internal retainer ?  It definitely isn't just pushing out.

      Help for a novice - fused spring bar

      By SamLiddle · Posted

      Alright, the job is done. I first filed down the stubs flat. I then used a Proxxon hand drill first with a 0.5mm bit to score a point to work from, then a 1mm drill bit to properly drill out some lug holes. I just went slowly, checking the depth as I went. I drilled the inside of the lugs, leaving the outsides unblemished. I was worried that drilling at an angle might be a problem, but it turned out fine. Lug holes don't need to be very accurate, so it was actually easy to create holes to easily accommodate a spring bar. The result is a 'good enough' outcome that worked for me. Thanks for your help everyone, loving the hobby so far. I learn so much with each project.

      Welcome to the forum. Yep not a cheap hobby by any means , Ali Express, the Chinese Amazon has some decent tools but should ask the members their thoughts before purchase.  A little reading to help you along. TZIllustratedGlossary.pdf
