Hi everybody,

 

My name is Rémy and i'm a 34 yo french boy from Toulouse (in the south of France) and i really need your help !!!

I've got a 6431/6445 movement (http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&ae&2uswk&Unitas_6431) from pocket watch and i would like to make my own wristwatch .

But there is a problem...i don't know if any case can fit with it...

Could anybody help me or send me a link for purchasing the wristwath case (and hands?) ?

I'm really a noob in watch repairs...so sorry if my question is idiot.. :)

Kind regard,

Rémy

First of all, this would make a 55 - 60 mm wrist watch, so think about real wearability. Anyway, you can buy this kind of novelty / fashion watches on Aliexpress for cheap, possibly you could adapt a case and dial to this mov.t

Anyway you would need to learn first and get tools, for a start check 

 

I also recommend you subscribe to Mark's HD lessons.

Hi, 

First, thank you for quick answer. :)

Are you sure that it will done a 55-60 mm diameter wristwatch? 

The 6431/6445 movement diameter is just 3 mm bigger than the 6497 movement and it is possible to find 40 mm diameter case for this last caliber. So why couldn't I make a 44 or 46 mm diameter wristwatch  case (without crown) with my 6431/6445 movement? 

Is it possible to buy a 46 mm diameter case for a 6497 movement on ebay and adapt it for my own movement? 

Kind regards, 

Rémy.

3mm is an huge difference in watchmaking. Your movement is for a large pocket watch, not a wrist watch, so you will have to be creative if you really want to case it as wristwatch. I recommend that you choose a different beginner's project.

      Elgin Grade 315: Runs/stops with dial down/up

      By docrpm · Posted

      Yep…This makes perfect sense. With that large a gap in the serial numbers, they were almost certainly machined on different equipment, hence one should have no expectation of any cross-batch compatibility. I’ll revert to the original bridge. Regarding bending the bridge @nevenbekriev, I’ll give it a try, but I may have to buy some better calipers. My Vernier calipers are only accurate to 0.1mm. Not very accurate.

      Yes, what I wanted to say is that the cock is part of the main plate, manufactured together with it and not meant to be interchangeable. Even if the other cock gets in place, it is not sure that the balance then will stay upright. You should use the original cock when it exists and is not destroyed. The adjustment needed by bending it is not irreversible. It is minimal deforming that is needed. No tools are needed. I have pointed to all needed references here for the balance staff endshake checking and correctness confirmation. The only tool needed for the correction is You thumb. The cock must be fixed on the main plate, no need of special plate with holes and so on. If You will feel more confident, then measure with Vernier caliper the height of the top of the cock where the stones are against the main plate bottom when the shim is fitted and try to reach the same height when bending the cock (with no balance in place!!!) Caliper with screw for fixing is perfect.

      Thermal Bluing Issue

      By LMS · Posted

      Thanks for the reply. I polished the head of the screw using 1500 to 10000 lapping paper and a screw polisher. This is why I think the head blued and the rest of the screw didn't. Silly question, how do you polish the whole screw inc threads, if that's what it needs to blue? 100% clean, Elna red and heated ultrasonic bath + IPA rinse. Finally, there is definitely heat leak as there's about a 30c difference between the brass bed and the soldering station temp. Having said that, the bed temp was stable. I will try to search out a better brass pot, but I haven't found one yet, hence the stainless steel bowl.

      Agreed but that's where WD40 excels, water displacement.

      Thermal Bluing Issue

      I would change the container to a thick walled brass one to start with. Looking at you screw pictures they don’t look shiny enough, really it’s best to do a black polish on them before trying. Also make sure once polished they are scrupulously clean, I dunk my experiments in acetone before bluing.   i think the thin walled stainless container to leach away the heat from the shavings, most successful bluing videos for example use thick walled brass to hold a good deep amount of shavings which acts as a better holder of heat.   Tom
