just received this one in the post, not sure if I have made an expensive mistake, all I know about it is it's a Dulux chronograph, it's missing the crown and was sold as untested. I think it has a Landeron movement but I can't work out how to remove the back and I'm too scared to force it. It has gold markers but rose gold coloured hands except the sub seconds which looks like a blued hand. Not sure what colour the hands are supposed to be. The case is covered in green from the brass strap pins but should come off easily. The good thing is when I give it a little shake the sub seconds ticks for a couple of seconds and the chrono pushers click nicely. The glass is scratched and the chrome isn't brilliant. What do you think? Any info would be appreciated. I won't even attempt to take the movement apart, that would be a very big mistake at the moment. Sorry about the pic I had to use my phone as I can't seem to upload pics on here from the camera. Cheers, Dave.

A pic of the back would be nice or it could be a front loader does it have a removable bezel on the front i cant tell from your pic.

 

I will take one when I get back from work, it looks like a snap on but there are no recesses or lips, the bezel does look more (roomy).

Looks almost definitely a snap back as the case is plated and the back appears to be stainless. The case looks pretty filthy so you may struggle to find the cutout to insert a case knife. If you carefully roll a scalpel blade round the join and look hard with a loupe you will probably find it

It's gunk from a reaction of the leather strap and the brass? Strap bars.

Sorry about the bad pics.DSC_0097.JPG

I'm going for Landeron 48, although it could be a 54. Can you see a calibre number stamped under the balance wheel?

Looks in a good state. Have you managed to give it a wind yet?

I can't see the number under the balance wheel, I've looked on ranfft archives and it isn't quite the same as the 48, 54 or 248. Did they differ slightly in the same movement at all?

It's not a 47. Very different chrono bridge.

Key difference between 48 and 54 is size, but they share many parts.  148 and 248 are later variants of 48.

If you are planning to tackle it yourself, you will need this... http://shop.joseph-watches.com/joseph/members/FMPro?-db=joseph_archive.fp5&-lay=web&-format=esemblo_details.html&kategorie=esemblograf&-recid=12607829&-token=002&-find

Thank you, I wish I was more clued up on part names and then I could have explained. They only made the 47 in 1937 didn't they? It must just share some of the same parts.

I have now taken the balance out Stuart and there is no calibre number anywhere.

      Vintage pocket watches from e-bay (winding stems needed)

      By Mallard · Posted

      Hi nickelsilver, thanks for the great explanation and the links! I'll take a good look in the article.  Especially this is great news to hear! Looking through forums and youtube videos I was informed to 'fist find a case and then fit a movement for it'. But seems that's not the case for pocket watches at least?  I guess I should be looking to find some 'male square bench keys' for now. I was thinking of winding the mainspring using a screwdriver directly, but I found a thread that you've replied on, saying that it could damage the spring.

      Murks, The rate and amplitude look OK, and the amplitude should improve once the oils you have used get a chance to move bed-in, also I notice that you are using default 52 degrees for the lift angle, if you get the real lift angle (assuming it's not actually 52) this will change your amplitude - maybe higher, maybe lower. I notice that the beat error is a little high, but not crazy high. At the risk of upsetting the purists, if the balance has an adjustment arm I would go ahead and try and get this <0.3 ms, but if it does not have an adjustable arm then I would probably leave well alone. Just my opinion.

      Epilame / Fixodrop

      By Waggy · Posted

      Maybe I'm over simplifying this and I'm a little late to the discussion, but just by my looking at oil when I use it on a treated cap jewel  the oil stays in one nice bubble, but when I don't it spreads out to the edges of the jewel. I'm not sure (but could well be wrong) but the analogy of a waxed car and rain is accurate in this case, the wax is very hydrophobic and repels the water, however, the process epilame works by is a different physical process based upon cohesion/adhesion (oleophilic) not repulsion (oleophobic)  at least as far as I have read/observed. If one were to use a oleophobic substance equivalent to wax (hydrophobic) then one would need to create a donut shape to fence in the oil, however if one used such a strategy with a epilame which is oleophilic then the oil would sit on the ring of the donut and not in the 'donut hole', exactly where you don't want it. Even if the oil is smeared then the oleophilic epilame should pull it back to the center (see diagram below). Reference For interest the chemical in epilame is 2-(PERFLUOROHEXYL) ETHYL METHACRYLATE, CAS NO: 2144-53-8

      Looks lint the teeth on the hour wheel aren't meshing with the teeth on the calendar intermediate wheel, maybe the hour wheel is sitting on top of this instead of meshing?
