Hello everyone, 

This is my second project after building the Skull Watch for my daughter's birthday. 

I also wanted a watch with a Swiss movement for myself; And I found a Unitas 6498-1 for this cool "B-Typ Fliegeruhr" project (that's German for a navigator type pilot watch). 

This time however, I've put my text and photos into the PDF file attached because its easier to edit that way.

Okay, and I'll post one teaser photo right here!

 

Cheers,

Mark

Hi Mark,

 

I enjoyed reading your last project and thought the idea of the brass strips in this watch was a great idea to overcome the problem of the gap.

It appears from the last timegrapher reading that the watch has a mainspring that is too strong. Was the reading the same after servicing the watch? Did you change the mainspring?

I had the same reading in a recent watch. It only had that mad reading after it was wound past three quarters full wind. I removed the mainspring and found that it was too thick, thus increasing the strength past what the watch was designed for. I replaced the mainspring with the correct strength and found it corrected the problem.

Hi Jon, 

the measurements were done on the watch before servicing. I look forward to repeating the timegrapher measurements after servicing. 

The movement was sold to me a New Old Stock. If this is true then it should have the original parts. Hopefully a good cleaning and fresh lubrication will fix it. Let's see.

Mark

      My first Gruens. Precision 510 and N510R movements.

      By rjenkinsgb · Posted

      Snap! I recently finished my Gruen 510 movement - though the case for mine is in a rather sad state; I'm going to try re-plating it (in nickel, it's not a gold one).   Re. the screws, I got a few of the one gram mixed batches from ebay. I've only needed a couple of screws for things so far, both rare, minuscule types - but both in the mix, after enough time sorting through them! The ones such as normal bridge screws are quite common in those lots.

      Any tips to correct a sloppy error?

      By rjenkinsgb · Posted

      Two pins or screwdrivers angled out slightly, pressing through from the barrel centre from the opposite side so they contact just clear of the hole in the lid? eg. Strap pin driver needles or similar.

      That's a good idea - shrinking down the nut and wrench size from the old casebook trick!

      Movement holder made with 3D printer

      By GuyMontag · Posted

      I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.

      Setting lever spring

      By Neverenoughwatches · Posted

      I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.
