I have three watches that I want to talk about. The first is a Seiko 5 that was working quite well and I thought I could regulated. Unfortunately it's stopped. Newbie mistake. I've now sent this one in for service.

 

The second watch is a HMT Kanchan Frankenwatch. I bought it for about $10 on ebay. It has a couple of issues, and I don't mind if I break this one. The first issue is that it keeps Bad time while I'm wearing it even though it keeps good time when I leave it on the shelf. I have discovered that the rotor can cause the balance wheel to stop in certain positions. The other problem is that The day of week indicator is off. I will start by trying to fix the first problem.

 

The third watch is a Sea-gull ST5. This watch reports good time when I use an application like a Hairspring on the iPhone. However it loses a minute or two every single hour. Any advice as to what the problem maybe?

If the rate of the balance is correct (as reported by and timing app or Time Grapher) but the hands are consistently losing time then the most likely culprit is a loose canon pinion.

This is a relatively simple problem to fix but must be done with care as it is also very easy to overdo it.

If you do a forum search on canon pinion you will find a number of threads that deal with this specific issue.

I agree! I have ruined many a cannon pinion...Its easy to overtighten them, but once you know how, it is a straightforward issue to fix.

      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

      By Waggy · Posted

      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?

      404 Club

      By Waggy · Posted

      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 🙂.
