Hi all! My first post so take it easy on me! 

Thanks for the awesome forum. I'm TK, lover of watches and tinkering. 

I recently acquired a Seiko Solar, SSC017 chronograph. 

Now I'm personally not a fan of chronos and actually, funny enough, sold this exact model not 6 months ago because it didn't get any wrist time. 

But this came up on marketplace as not working, and it looked clean enough so I bought it for $50. 

It was actually an extremely easy fix to get it running again, simply reset the solar by holdi down the Chrono pushers for a few seconds. I had to remove the movement in order to push the pusher buttons, why you'll read below.  

Now the bigger problem that I have, and I'm quite certain it was not the reason this little girl sold it, is that the top chrono pusher, see the picture but you know the kind that you have to unscrew in order to use it? Well I found out when I went to reset the Chrono that the pusher works fine, it's just that locking collar is stripped, it turns very stiffly but it will not actually unscrew to enable me to use the pusher. So while I have everything else working fine and I actually have the pusher removed, I'm stuck at being able to remove locking collar from. I'm assuming the threaded tube. Sorry if this is long-winded. I will include any pictures if somebody requires them. I'm just trying to figure out what to do next. I could take it to my Seiko dealer but I lost all confidence in him and regardless I'd like to do it myself if it's possible.

Again, thanks for the add and thanks for any help you can offer.

    • So i've been trying to source a bellmatic dial for some time that's compatible with the bellmatic i own and theres a handful on ebay but none appear to be compatible. Ebay japan doesn't even let me look at listings but i've heard of various ebay like sites in japan where users sell things and it seems like seiko parts like that would be a lot easier to find in japan. I'm not looking for a watch parts specific place but just a place where people in japan would sell watches to each other and parts and that sort of thing among whatever else they want to sell. the phillipines and thailand also seem to be a pretty rich place to find seiko parts so if there's a market in those places i could search too that anybody knows of that might work also. I've heard of a few over the years but i can't remember the names of any of them. Any help would be appreciated.
    • Thanks! You learn something new every day. I wasn't sure about the difference between a beat and an oscillation. So good to know. 2 beats = 1 oscillation.  I sure will. It's going to be interesting. So far I've turned the balance near 300° before letting it go and on a really healthy balance it has been swinging for about 70-90 seconds in the horizontal positions. Anyway, when doing the test, I'll only swing it 180°. I will be surprised to see it swing for only 25 seconds or less, but we shall see. That could be because I've never tried to count oscillations and only assumed it would be impossible or difficult. Anyway, let's see when I get a chance, hopefully in a month or so as I'm still on vacation and far, very far, from a workbench. Here's Kalle Slaap doing the kind of test that I do (start at 12:30). An interesting observation is that when Kalle starts the balance towards the end of the video at 14:40, it oscillates for about 50 seconds before the video ends. It is difficult to judge whether the balance swings more than 180° at the start, but it looks like it could be close to 180°.  
    • Thanks for the comments I ‘ll pay attention to both points. 
    • I noticed at 0:25 the balance stops because it touches the movement holder. Be aware of that, because if you tighten down the movement holder and something is contacting the balance, you're going to have a Bad Day. When you remove the setting lever spring, I've found it's helpful to loosen the screw a couple turns, then lift the arm of the spring off the setting lever to relieve tension on the spring. I do the same thing for installation--get the screw started, then put the spring arm over the post on the setting lever. Otherwise looks okay to my amateur eyes.
    • Welcome @MartinF! Nice to see more Scandinavians. I myself live in Sweden but have Denmark in my heart. I couldn't agree more. Never use force. Get a bigger hammer! 😉
