Hello All,

Just a quick question here. Had a older Seiko watch that is totally rusted and the cell look like it leaked also. I've been looking to see if i could get a replacement movement for it. But unable to get a 5Y39-4120 from any of my normal suppliers.

 

caliber: 5Y39A

size: 10.5

stem 351-670

battery: 371

function o. SC-D(3)

hands 0.65x1.10

 

would a VX39 work as a compatible?

 

caliber: VX39

size: 10.5

stem : 354-531

function SC-D(3)

hands: 0.70x1.20x0.20

 

Not sure what the hands size would mean and not sure what 0. sc-d(3) vs sc-d(3) under function means

 

I did call Seiko and they said they to see if i could get a replacement moment from them but they said they don't sell movements but did have it in stock if i wanted to send it to them and then get a quote.

 

Was kinda odd since I've always gotten parts from them before crystals/stems/crowns and so on.

 

Any insight would be great

 

Thank you

Here the watch i already check ebay for the same moment but haven't found one yet also notice that most movements has the wholes on the opposite sides.

Here is the movement after a soaking and cleaning already

couldn't get the all the rust of of the one wheel but got most of it off.

I could clean all the rust off of the plate with some sand paper but didn't really see a point since even after a overhaul the watch wasn't running either way the pulse test seems to be a negative. I assume this means the coil or the quartz circuit needs to be replace.

 

Also i believe a 7N32-6 should be a proper replacement for this watch i will most likely give that a shot. it has nearly the same size, has the hole on the right sides and has a cal at the 6

 

• Has 1 jewel
• Stem: 351892, Tap 11
• Date at 6
• Genuine Seiko quartz movement
• Japanese assembled


7N32-6

10 ½

2.50

110/65/20

      Hi Richard,  I keep buying CAL.59 movements to practice on 🙂 Not started yet though, I'm gathering tools and building my confidence to start.

      No main barrel endshake on Waltham model 1900

      By AndrewSi · Posted

      Problem solved. For some bizarre reason, the hook on the wall of this barrel is not properly centered vertically, but is oddly high on the wall, maybe 3/4 up the way up. When replacing the mainspring, this caused the outer coil to be displaced upwards as well such that it protrudes out of the barrel and caused the barrel lid to not sit quite flush to the barrel. Since this is a motor barrel, the lid is actually the first wheel and inner coil tube/hook all in one piece, with no “snap down” action that would have made the problem more immediately obvious. Maybe with an older mainspring the spring’s end hole was enlarged such that this wasn’t an issue, but hard to say how it ever worked otherwise. Replacing the barrel with one from a different model 1900 where the hook was properly vertically centered allowed the lid to sit flush without mainspring interference and the friction problem went away. The bridge was far too thick to be bent (and isn’t), for those of you thinking that was the problem. Placing the removable arbor in the watch without the rest of the barrel proved that the proper end shake was actually there as long as the overall height of the assembled barrel was correct.

      Mainspring winder question.

      By Jon · Posted

      You are so true on a lot of what you have said. The main reason for changing the mainspring even if the old one is in good order is because it will take out your thinking that the mainspring is contributing to poor power output or fluctuations in amplitude. If a new spring is fitted that box can be crossed off as a potential source of a problem. Most customers are happy to pay the extra £20 for a new mainspring if they are already parting with a couple of hundred pounds for a service. A new spring is an investment for good running for the future.

      LeCoultre Memovox dial and escape wheel.

      By nickelsilver · Posted

      According to Borel the 814 and 815 use the same escape wheel. It's kind of an oddball being so long.
