My son's SNK803 (7s36) has a weight on the rotor that has separated. I tried to glue the weight back to the rotor as there was crosshatching that made it look like that might work. No dice. Any ideas how to re-attach the weight? The watch is $55 on Amazon, so I'm afraid to even consider buying a new rotor (can't find a source on google so far anyway) as it'll probably be as much as the watch itself (or a significant percentage).

Ideas?

Clean both surfaces with scotchbrite pad and rubbing alcohol, let dry, use new tube of a decent brand cyano-acrylate glue such as Loctite or Crazy Glue.
If for some reason that does not work there is a 2-part epoxy made for attaching heat sinks to electronic chips that should work - in fact, any 2 part epoxy should do.

The weight is spot welded together, so not really a fixer.
Just put one on from a 7s25/6 or 7s35/6, they're all essentially the same (some are a half circle -others are slightly smaller in angle - like a smaller wedge).
Put a WTB on the trade forum with a pic of your rotor - someone will have a spare kicking about.
Where are you located???

I considered solder, but was worried about material buildup, but yes, looks like a spot weld was OEM. I'm in Michigan.

I have several used spare 7S26 osculating weights in my collection part 509074. They are not brand new but all are in good shape and the bearings only have slight wear no major wobble. I'm pretty sure you can use the rotor off the 7009 as they are identical in overall shape with just a different pattern cut in the face. Let me know if you can't find it local and I would be happy to help you out. I do have a couple of brand new ones also but I can't see the advantage of spending the extra money to get a brand new one when the used one will work just fine.

The fact that it was spot welded in no way means it's "not really a fixer". :rolleyes:
If you're in the middle of the back of beyond and you need to fix your watch, because you really need it - feel free to glue it together with camel spit, spinifex gum, lizard jizz, ticky tack or whatever you want to use. That's an acceptable "technical repair in the field".
If you do the same thing in a location where the correct part is easily available and the repair takes it back to factory spec - then that's a BODGE - and should not be advocated as a sensible plan of action on a watch forum ( unless there's a "cobble together some tat" sub-forum) :rolleyes:.

Jeeeeeeeeeeeeze just replace it !! :)
+1000 I offer you a free rotor as well as another member though I don't know where your located. As long as you in the states or even the UK just ask and within a week you will have free and proper fix.

On a second topic I can't help but notice that the movement is a 7S26C. I have heard several complains of people who purchses newer Seiko's powered by the 7S26 and they all had one thing in common. The dial said made in Malaysia which means the 7S26 was assembled in China and complains seem to be more frequent especially with accuracy. Some being as fast as over 5 minute a day. Unheard of from the 7S26A.

This ended up being a true facepalm moment as I read the comments and realized, I must have a carcass on the bench with a 7s26 rotor in it? Lo and behold, yes, I did (SKX131 I think?). So, junior has his watch back, he's convinced dear old Dad has a clue, but you all know otherwise!

No need to be offensive. I offered a perfectly reasonable fix that could be done "while he was in there" in a matter of a minute or two without having to put the watch aside for a week while a replacement part was sourced.

I wasn't being offensive, I was stating the truth, and you didn't at any point in your post say that you were offering a temporary fix - so stop back-pedaling.
Epoxy hardens exothermically and gives off volatile chemicals because of that, so if it's locked inside a watch case for a week (for your temporary fix) - will it attack anything in the movement or on the dial/ chapter ring or hands?? I don't know - do you??

No backpedaling at all and I never said it was a temporary fix. Not sure why you're so threatened by someone suggesting a fix you don't agree with but that discussion is probably beyond the scope of this forum.

{"while he was in there" in a matter of a minute or two without having to put the watch aside for a week while a replacement part was sourced"} AKA temporary fix.
You don't present any threat, whatsoever.
