I picked this up at an op shop (charity shop for non-aussies) recently and I've been unable to find anything about this "brand" at all, though searching for "17 jewel incabloc" turned up a lot of very similar looking watches with different brand names on the dial. I assume it's some sort of cheap knock-off or something. However, I'm quite taken with it. I removed the movement to have a look at it and without the knackered crystal, the dial is quite lovely and the movement is running very well. I'm tempted to get a new crystal and get it serviced (i don't have the equipment to do that myself, nor do i want to make a mistake and spoil the watch) - but I'm not crazy bout the case. how easy is it to transfer a movement to a different case, in general? The movement doesn't appear to have any branding beyond "seventeen jewel swiss made", so beyond measuring it and hoping for the best - are there any tips or pitfalls to avoid when shopping around for a potential new case? or would it not be worth the hassle? cheers in advance for any info or advice!

There's not a lot of information on Sonora out there but it was a brand name registered by Complication S.A. in 1953 in Switzerland. I would say that your watch is more 1970's in design.

If it has Incabloc shock protection then it is unlikely to be a pin pallet movement inside. More likely to be a fully jewelled movement, possibly something like an AS1950/51 or similar, however a pic of the movement would help, and better still a close look at the main plate under the balance wheel.

As for re-casing it you have two options.

1. Find any case that appeals and is physically large enough to accommodate it, and then make up what ever spacers are needed to make it actually fit.

2. Find a donor watch that has a case you like and uses the same movement and dial size as yours and swap it out. But for that a positive movement ID would help.

Hey Marc, cheers for replying. I forgot to photograph the movement, helpfully, but I'll take one when I get home.

I can see an "AS" under the balance wheel, (impossible to photograph) and there's some other figures that I can't quite read but I'm hesitant to remove it since I'm still very much a n00b at this.

That's an AS/ST, probably a 974 since it has a calendar. I would also have said 96 except that I can't find a calendar version of that. A closer look under the bridge where you spotted the AS should show a number.

The exact same movement could also be labelled FHF or FHF/ST, or just ST.

It's a good work horse movement which was used by many brands in the '60's through to the '80's in one variant or another so you should be able to find plenty of donors that could furnish a case.

If you look here you may even be able to find a new case to fit as the TimeZone.com watch school used to use the ST96/7 as one of their learning movements.

okay, so I decided to remove the balance wheel to get a look properly. Clearly I needed my glasses on as it now clearly says FHF ST 96. but either, sounds like the same thing. That's great though that I can get one of those cases for it :) thank so much for your help!

    • Righty ho, I re-serviced the chrono module and got a reasonable result with minimal loss of amplitude when not running the chrono and about 30 degrees loss when running. Great. The problem is now that the chrono (and movement) stops running after about a minute or so, a tap on the watch starts it running again. No issues with the movement running when the chrono is stopped. Going to service it yet again, obviously some residual issues with friction in the chrono module (Very frustrating - I wish there was some way of testing it as I go!) I also seem to have a problem with the cannon pinion where the movement is running continuously (with the chrono stopped) but it's losing significant time / stopping. This is one of those two piece ETA style with a driving wheel pressed over the cannon pinion, obviously arranged for driving the chrono module. I had no issues with this prior to service and just added a small amount of grease between the driving wheel and the centre cannon pinion as the technical guide required. What's the best way of tightening these up? I would like to replace it but I guess this is going to be hard to find as it is dedicated to the DD chrono movement. 
    • He uses the micrometer cap, but he leaves the spring out (you can see that in the video). If you leave the spring in, the spindle will move up as well (as shown by @Knebo).
    • Seems like he doesn't have the micrometer cap  attached to the spindle so he can only push down but cannot pull up? If the cap screws into the spindle I guess you don't need the spring? I only have a "normal" Seitz so I really have no idea. 
    • Do you have a part number for the bearing shim lock tool?
    • Yes in my opinion the 3/4HP is plenty but it’s your decision & yes it does come with speed control but foot operation so my reason for changing to potentiometer was because my leg shakes so it was like me revving the lathe & anyway I prefer to set the speed. I & a few others that I recommended the motor to run a Pultra 10mm lathe so if you have a 6 or 8mm B & L then it will be plenty, if you have seen any of my videos you will have seen that when using a graver I run quite slow without any problems.
