Starting a 7t27/ym57a - chrono fine, watch not

[tIB]

Looked like the tip of the hour hand was catching the shaft of the subdial - there's quite a bit of play in that hour subdial so I'm guessing each time it caught it stopped it a little to the point where it was at the bottom end of its range of play - assume I missread the four hour difference as I only saw it once.

 

I've had a fiddle and will see how it behaves...

A little update on this - all seems to be behaving since refitting the subdial hand. It hasn't had too much wear as I've been away, but in the few days prior to leaving I had no issues and it's behaved while away. 

 

Think I'm calling this one done!

[tIB]

Yeah, it's not behaving! I'm four hours fast again on that subdial. Who knows - while I have a set of spares from the movement I removed I think it's beyond my skillset and will probably stay in 'dual time mode'(tm)!

[tIB]

Had another crack at this - the hour sundial hand stayed at around 4 hours fast, so I figured it was time to remove and reseat it... I'll be back in a month or so!

So it ended up about 13 hours out somehow! I thought there was an issue with the hands catching (related to my relume) so I took off to fit another pair, one of which killed the plastic hour gear!

 

Not gone well then, though fortunately I kept the old movement for spares, so I've managed to get it all back together and working today after much messing with the date change...

 

I wonder if the date change gear was causing issues, though might be that I reassembled wrong - it wasnt happy but after changing the gear and plate from the other movement it's all working again. 

 

I'm really hoping the hour hand issue is sorted - feel like I deserve so e good luck on that front but won't know for a week or so... I'm likely out of my depth here!

 

A picture to mark the rare occasion that hour dial is more or less correct!
