Purchased this Zodiac aerospace gmt calibre 75 a few months back, it was a none runner & in a bad state of repair. During the teardown, clean & service, I replaced the offset cannon friction pinion, mainspring, a few screws & a cap jewel. I managed to source a NOS original dial, rhodium plated the bezel & repainted the worn out numbers. Swapped the rough hands & replaced the cracked glass. post-641-14524288851635.jpgpost-641-14524288935922.jpgpost-641-14524289005997.jpgpost-641-1452428907512.jpgpost-641-14524289106469.jpgpost-641-14524289166161.jpgpost-641-14524289342383.jpgpost-641-1452428951987.jpgpost-641-14524289644183.jpgpost-641-145242898154.jpgpost-641-1452429007341.jpgpost-641-14524290156563.jpgpost-641-14524290364343.jpg

The Omega De Ville. I bought the case as NOS a while ago for a different project that didn't happen, I had a 620 movement in my spares box, I then found a dial & hands on the bay. Then gave the movement a clean & service etc. Cleaned the dial, bought a new glass, replaced crown & reassembled. Looks good I think. post-641-14524295940832.jpgpost-641-14524295995294.jpgpost-641-14524296027249.jpgpost-641-14524296073662.jpgpost-641-14524296105872.jpgpost-641-14524296220873.jpgpost-641-14524296280368.jpgpost-641-14524296336483.jpgpost-641-1452429642599.jpgpost-641-1452429647232.jpg

That's a great result DJT2, both watches look excellent!

Thanks Geo, the biggest issue was finding a replacement offset friction pinion for the zodiac. Tried everywhere & kept getting the same result "obsolete" then I started looking at the movement it was based on, the AS 1687. Again same result, finally I tried another movement that used the AS 1687 as the base movement. The Favre-leuba 1149, tried cousins & they had one for that movement. Purchased it & it works perfectly.

Outstanding! I'm hoping that I'll be able to do similar kinds of things in the future. Getting there, slowly but surely!

Thank you for kind comments, it's been slow process & a big learning curve for me. But I'm finally getting there, I still need to conker manipulating the hairspring, It's a real pig for me.

A couple of nice resurrections, I particularly like the Zodiac.

 

What is the regulator arrangement on the Zodiac? It looks like it's some kind of micro regulator but I can't quite make it out in the photos.

Hi Marc, Yes your correct, there is a micro regulater. I've enclosed the link for my full teardown & better pictures.

Thanks Marc, I tend to take a lot of pictures when I teardown as I still need a road map to reassemble. The hardest thing I find is remembering which screw goes where. That's why I take the individual pictures with corresponding screws, it helps but sadly it's not a fool proof method.

I actually have a dedicated watch bench camera to record anything that I've not seen before, and any movement that I've not worked on before gets the full photo treatment.

 

For making sure that the right screws go back in the right place I'm in the habit of putting the screw back in the hole it came out of once the bit it was securing has been removed.

If you look at any of my photo walk throughs you will like as not see all sorts of screws sticking out of the main plate for no apparent reason.

 

Of course it does assume that the screws were all in the right place in the first place, and it does slow things down a bit, but it reduces the risk of losing a screw, and it does mean that each screw goes back where it came from.

      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 ÂŁ20 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.
