A good grade unitas 6497, finally rebadged as ETA.

Definitely not a UT6497, the train layout is completely wrong for a stem at 12 and a sub-seconds at 6.

Not a UT6498 either as although the bridge shapes are very close, the layout of the Crown wheel, ratchet wheel, and the click is wrong. I suspect that it's not big enough for either of these calibers too as they are 16.5'''.

I think it is UT though, possibly a 196, 197, 198, or 199, which are either 10.5''' or 11.5'''.

I think you are roght, Unitas 6431 is more like it, I didn't check this on Dr ranfft site and am not sure if they are of one family generation, not that prices are any different.

The one out of solar says 2adjut, better grade than unadjusted, so I stick with the price though JDR just wants an idea to decide how much to spend on em.

Gear bridge on the last one posted( out of winsor) seem scavanged off of a donor, a turn off by itself. wouldn,t spend much on it.

 The solar looks worth a decent service to me anyway.

Marc and Nucejoe.  Big thanks for this track down and I will spend more time with the SOLAR watch, starting with a hand cleaning of the case (or ultrasonic). Need to see if I can recondition the crystal as well.  And then there is that old strap.  Have never done any leather strap work but would love to get is to shine again.

But this morning is Rolex Oyster Everest Precision (1957) review and perhaps start the disassembly with very shaky hands:)

Oh shoot, lots of variants were made, I hope its a Unitas at least. 

Jd always works on ole good grades and making a staff  again ALWAYS is a pre-requisit.

Regards

That winsor can be a fhf30 variant. Rolex 59CS is based on fhf30-1. worth furthure search, the movement itself isn't worth much, but some of its parts might be rare.

Hi Jd,  So far as I can tell the windsor movement looks fhf30, I am not sure what parts interchange with fhf30-1= Rolex59CS.

Comparing the keyless helps, set spring on a Rolex fhf30-1 is always broke. I think windsor can worth more as a donor to a Rolex and hardly worthy of fixing as a windsor watch, bridge layout usually wont help much with interchangability not as much as a datasheet anyway.

There is always the question of high precision Rolex gears as well.

The marking is UT and 199. So not sure this is a 6497. It has cap jewels on the 3rd, 4th, and the Escapement.

So its back to what Marc was saying all along.

Dr ranffts does list UT199 though shows a different bridge layout.

Says adjusted in 3 positions so you might regain the precision with a good polish of pivots and poise,  then there is the question of hairspring originality/quality .. etc. Though the dollar value might not justify all the work to regain the precision.

I have got a thing for these generations of Unita movements and  personally wouldn't base my decision on dollar worth, but then this was your question from the first.

Good luck and a very happy Chirstmas to you and your familty.

Regs Joe.

I now need a 3rd wheel as the pivot is broken.

      1972 Bulova President "E" Sea King 11ACACB movement

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      By GuyMontag · Posted

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
