Hey guys!

I was wondering where I could find parts for this watch.

Story: My Lemon dial PN's movement was shifting around in the case, and at one point the shifting knocked the coronet off the dial! I opened it up to do the necessary surgery, and found that the case-to-movement standoffs were bent at a 90-degree angle. Good news is I did manage to get the coronet secured back on the dial, but the bad news is I tried to bend the standoffs back to less-than-90, and in the process, one cracked, and the other snapped (on a second bend attempt, it hadn't snapped the first go-around). One thing I did noticed, however, is it seems like the standoffs were too long for this case/movement combo - when I tried setting one when it was unbent, it simply wasn't the right geometry - the length seemed to be keeping it from sitting at the right angle to get the screw in the standoff hole and then into the movement hole to get it screwed down nicely.

All this to say - I need a pair of those case-to-movement standoffs, and one of the screws (lost one in the process of trying to get it screwed back in).

It's a pretty specific part, I'm not sure if generic solutions will work, so wondering if anyone has insight? @yodog @tripdog, @kilowattore... maybe some of the other greats that have built/worked on these pieces?

Did a little research and found that I'm using the wrong terminology - they're "case clamps," and there are several options online to buy - with screws!

If anyone knows the best size for this setup, pls let me know, thanks!

Honestly, just get a kit with the various sizes and find the perfect match. I've found its not always a "one size fits all" kind of deal

Will do. Measured them, though, and it's looking like the clamps that came with it are 1.5mm wide, and just under 2mm long? A unique size, not one I'm seeing readily available. I'm gonna stop by my local watchmaker's shop tomorrow and see if he'll let me grab a couple from him.

Personally I wouldn't bother searching for a single couple of clamps and get the mixed size box. You really never know which one you'll end up using, they're cheap and you'll have some spares for future use

Old post but for anyone else looking for the perfect clamp, just dont. Buy a box of various sizes and sand down a longer one to get a perfect fit. They're just thin bits of fairly soft metal, not hardened billets.
