I have a Seiko Kinetic from the mid 90's. I got it second hand. The case seems to be in great condition, so either little wear or the watch was well looked after, or it was not worn a lot. 

When spun, the watch will begin to tick, but it will only tick as long as it is being spun. Sometimes, it doesn't spin even when spun if it is too light of a spin. Seems to hold no charge, or maybe there is something else wrong with it.

Seeing as it is old and a new capacitor wouldn't hurt, I will probably replace it, but I'd like to know if there are any other tests that I could do to find any other issues without manually inspecting each piece? I have done very little work on kinetic watches, so I am not all too knowledgeable.

It's not a universal consensus that they're no longer called capacitors though, even if its technically accurate. For example if you get the replacement from Cousins, they still refer to it as a capacitor and so be aware of that when sourcing the replacement. Just so you can avoid confusion.

Cousins is  just a re-seller which like many others names them wrong. Seiko and the battery manufacturers calls them "lithium rechargeable battery".

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      I kind of think the same, the surface under the oil is the same as the surface around the oil. Can epilame both repel and attract , that doesn't quite make sense in simple terms, but is it more complicated than that.

      I agree with @JohnR725. Oil on an epilamed surface is essentially the same as water on a waxed surface. The same physical properties are at work (surface tension vs. adhesion).

      Without Our Forum

      I think we all get a lot out of this group, and it has been pivotal in my development by the sharing of knowledge, experience and learning from more seasoned experts such as @JohnR725 and others (you know who you are!) as well as fellow novices. I think that having a backup communication plan in reserve so that if there is a future problem just makes good sense. I don't think anyone is trying to undermine the forum, but if something unthinkable happens, like the Ranfft website for example, then it would be good if those who are willing can still keep in contact. Speaking personally, and I know I risk a charge of heresy, it would be good if Mark could be a little more visible in this forum, and maybe give any insight from time to time on the future/progress of forum and instructional videos etc. even if its just to confirm the status quo. I appreciate he is a busy man with a full time job, but so are most of the rest of us and to post a few lines every now and then shouldn't be too much to ask to reassure the restless villagers. Best outcome for me would be a message saying something along the lines of: "Hi guys, all good, no planned changes... enjoy the forum, will message again next month!" Just my two cents.

      Omega cal. 565 - low amplitude

      A nice looking watch !! Did you try 9010, instead of the 9415, on the pallet jewels / escape wheel? And if you did, did you notice a difference?

      Knocked out another 404 last night...when you are in the zone! This watch was a non-runner which I picked up as part of a lot of 8 watches, so works out to be $3.12 per watch. Before:   And the finished watch, new crown and stem and the crystal was cracked so was replaced. I also replaced the mainspring as the original was the old steel type spiral and very 'set' - all else is original: The Movement was a AS 1686, but in reading around a little the ACCRO watch company were sued for their use of the five point crown on their Jacques Pere range as it resembled Rolex, see below: ACCRO then reverted to just ACCRO on their watches - I have done some sniffing around the internet and haven't seen another example of ACCRO and the crown together on a dial so maybe I have something unusual, or maybe I was looking in the wrong places 🙂.
