Hey guys.

Anyone know anything about these gruen mainspring barrel set up

The arbour is attached to the barrel lid and spins . 

Before i attempt to remove the arbour i thought i better check to see if that's the wrong way to go.

The problem is you cannot see when the mainspring is attached to to arbour.

And i have tried a number of times, sometimes it feels as if its caught. ( it stiffens to turn) so you start to rebuild the watch and hey and behold its not caught at all when winding.

so any thoughts. cheers

      Stem broken - can it be rescued?

      By watchfellow · Posted

      I think that a 814/825 stem would work, there are a lot of compatible parts between these.

      Venus 178 hour counter creep

      By watchfellow · Posted

      Hi everyone, I put together a Venus 178 recently, but found that the hour counter "creeps" ie. runs when the chrono is disengaged. This is the similar type of setup as the Omega 861, where the hour counter is driven off the mainspring barrel, but stopped when the chrono is disengaged by a friction spring.  Am I correct in assuming that the friction spring for the hour counter driving pinion should be dry? I am guessing that the issue will be either the spring or the driving pinion, but while the driving pinion has some wear the spring looks decent.  I've attached a couple of photos in case anyone has any tips. Thanks in advance!

      Setting power reserve on LeCoultre Futurematic

      By watchfellow · Posted

      Thanks everyone for the replies. It seems setting the hand is a bit of a guessing game, and I thought there would be a very specific way to do it. Since the reserve indicator hand moves clockwise as the spring is wound, I tried setting it right at the start of the black side. But setting it there doesn't really make sense, because by the time the spring is halfway wound, the hand is only at the end of the red side... In my head halfway wound shouldn't mean the hand is still "in the red."

      Lovely part of the country! I spend most of my days driving along the A64 for work in and around York. I'll be sure to drop plenty of questions soon! I've actually got a couple of watches on the way that I'm pretty sure I'll need some help with! They look pretty beat up from the pics but I love a challenge and an excuse to buy more tools 🤣

      Help - London Elliott Mantle Clock Night Silence

      By oldhippy · Posted

      I have two of these in my home. You need to remove the movement from the case, take off the hands and remove the dial and take a few good photos of the front plate so I can see what the problem is. The round nut unscrews and the hands pull off pull them off from the center and not the tips as you could break them.
