Whenever you see a Longines like this for $60, buy it. I think you can at least triple it [emoji3]
I'd like to see a link to that listing, if you have it.

Can’t find the original listing. Here is a similar listing. Similar in the face. I did not compare movements

Yeah, it's not serviced though and parts are nearly impossible to find. It also has a loose crown. The main thing is that it has a diameter of 33mm and my ref 6417 is almost 36mm. Like you said, the movements are also different.

I can just imagine all the little springs in that one.

The jump hour above Yankeedog?

Surprisingly fewer than I expected, only jumpers and clicks for the date and hour wheel. The minutes is directly driven from the equivalent of the cannon pinion, (this being a pressed fit centre wheel) and then the sweep seconds as normal.

You can see the innards of it here. I had no intention of filming this one as it was my first jump hour and I wasn't certain what to expect but the difficulty removing the centre wheel led to the video which is a bit choppy in procedure due to the above reasons.

If I get another I'd enjoy doing a proper strip and service video.

Pictured yesterday, this early ‘60s Josmar, a brand founded in 1928 by Kocher Freres of Bettlach and entirely unrelated to modern watches of the same name. 

Josmar used various movements in their watches, this one having a 21j Oberon pin-lever movement, a subject for another day.

Regards.

Following on from yesterday’s effort, today it’s the turn of this 1950s Oberon from Erwin Rudolf’s now largely forgotten Oberon Watch Co. It has absolutely no connection to the modern day “Oberon” brand and came as something of a cosmetic and mechanical basket-case, needing a strap, new crystal, replacement sweep seconds hand, new crown & stem, new mainspring and a service.

Instead of using their own Oberon calibre, this one runs on a similarly obscure 17j Brac 903, unfortunately absent from the usual archives although it is referenced in Bestfit.

An interesting little company and one who, probably on the grounds of cost, initially used their own solitary movement before sourcing from other, more established, makers.  

Regards.

Cool. That minute track moved inward is a nice unusual feature.

Terms like “De Luxe”, “Extra Special” and suchlike on things like these are almost always a sure-fire guarantee of utter rubbish, and that’s before you even get to all the nonsense usually engraved on their case backs. So this effort was bought for 199 pennies some years ago as a non-runner, purely on the remote chance, just maybe, that something interesting lurked inside.

Well, of course it didn’t, but sorting its mighty 1 jewel Baumgartner 866 gave me a spare. Like I needed another one of these.

The movement is signed for Constructa, suggesting a connection with that Mondaine-owned pin lever outfit. The Ackro name appears to have been one of several used by Gaumont Watch Co of Manchester who would have been the importers before offering these things to the unsuspecting  public.

And I’m afraid that this beauty warrants neither a new crystal nor a permanent strap.

Regards.

Perhaps a little harsh, although I agree that it is not a high end piece, these pin lever movements are still an interesting engineering challenge, well executed. Think of it as the Swatch of its day, engineered to a price.

The fact that it is still working all these years later, and with all of those battle scars tells you that despite the low cost bill of materials, the engineers at Baumgartner were no fools.

I think it at lest deserves a quick sand and polish of that scratched up crystal, as most, if not all of those surface scratches look like they would be easily addressed,  though I must admit, I would probably not replace the crystal either.

One other point, I suspect that it has a rarity value, that your average Rolex from the period does not. Few of these will have survived (perhaps for obvious reasons).

All understood thanks, Andy, and with (currently) 70 various pin levers amongst my rag-tag collection, I have a fondness and huge admiration for what could be made out of not very much, as evidenced by the fact that they are still going strong after so many decades.

Not having been bought for any aesthetic value, this particular one doesn’t, and probably won’t, see any meaningful wrist time so is likely, if somewhat unsympathetically, to remain a potential donor for something a bit more deserving.

Cheers.

They do turn up in some interesting watches, this for example according to the seller has a BG 866 variant.

.. and I must confess that if one of those turned up in need of parts, I  too would be tempted to perform a partial brain transplant with the poor old Ackro De Luxe as the victim. :D

That's exactly the same as my Trafalgar, (see top of page) which has a bfg 866 1 jewel movement, really nice watch. Mines the most recent service and keeps time surprisingly well for the movement type.

    • Re. rust removal: I'm using a formula created by one of the science channels on youtube (Elementalmaker).   It's cheap, not acidic and works in a similar way to  evaporust, but seems milder. It has worked well on everything I've tried it with so far, with no detrimental effects. The formula is: Per 100ml deionised water; 5g Tetrasodium EDTA [from amazon or ebay etc] then enough citric acid to bring it to ~6.5ph, testing with ph paper, plus a few drops of washing up liquid / dish soap. I've only made one, 100ml batch so far and it shows no signs of stopping working, though it is starting to look a bit murky!   These spring winding arbours were the worst rusted items I've put in it - they had quite heavy scaled rust patches; you can see the darker grey areas where the rust ate in to the metal, compared to the untouched areas. The small clock parts are unaffected by the solution, other than the rust having gone. (I've also used it on such as setting levers & other keyless components, that had quite significant rust from water ingress).
    • No, the Peseux 7040 is doing very well as far as the rate (and amplitude) is concerned. The maximum delta measured was 20 seconds between fully wound, crown down (+8 s/d) and fully wound minus 24 hours, crown up (-12 s/d). Compare that to the ETA 2763 having a delta of over 80 seconds. What I was trying to convey was that I observed that the much higher amplitude of the Peseux movement during a 12-minute measuring period could momentarily fluctuate by 30° just like the much lower amplitude on the ETA 2763. I haven't studied the History graph on @praezis PCTM software for any other than these two movements but I wouldn't be surprised to learn that these fluctuations in amplitude during a 12-minute measuring period are the rule rather than the exception for all typical non-high-end-chronometer movements.
    • I'm presently using a cheap supermarket ultrasonic cleaner, with L&R #111 cleaner and #3 rinse solutions. I cut a bit off the bottom of an appropriate size plastic sports drink bottle, which is a perfect fit around the mesh basket I use (~65mm diameter). That allows me to use mostly water in the machine tub and cleaner or rinse only in the small plastic container. I keep the solutions that are still fit for use in small glass jam jars. I use the cleaner then two rinses, then the mesh basket balances on my bathroom radiator (once it stops dripping) to dry the parts with moderate warmth. Prior to that I tried just lighter fluid (eg. generic zippo fluid) and just soaking / swirling parts in the glass jars, but the movements did not run at all well afterwards, they were still acting gummed up. The proper solutions make a world of difference & the watches now work as they should!    
    • Have to agree with you. Will not do another. Did not enjoy the time spent. However, it was worth it to know that I understood how to disassemble, look for defects, repair and then assemble. Timegrapher? No facility to alter anything other than the stud. Everything is metal to metal.
