Beginner's luck, AKA Jason's first attempt at regulating...

Recommended Posts

My Autavia 11630 has been losing quite a bit of time recently. So I decided to have a go at regulating it myself. I've bought a Timegrapher to make things more easy (the iOS app I've got on my iPad is ok, but you've got to get the mic on the headphones in just the right spot and keep it there for it to be effective).

Anyway, it probably wasn't the smartest thing to do, starting on something as complex as the Cal 12... especially when you take the back off and the regulation isn't as per Marks excellent instructional videos and articals. It's done via two screws on the balance bridge, the one nearer the jewel affecting the rate, and the one furthest away the beat. Both screws are excentric and shift the the hairspring appropriately.

That said, after 15 mins of working out how it all relates to one another, and seeing what it was doing - this is what I've managed to achieve. Pretty chuffed. :woohoo-jumping-smiley-emoticon:

So it shouldn't have been loosing time if it had been or if it had they didn't do a very good service it should have been checked and regulated and be good for a few years not a couple of months.

    • Thanks Stuart for the links to Borel and Cousins.  It has been helpful to see what parts are still available for this caliber.   What is the homemade tool you refer to? I have rewound some hairsprings on the 6497 clones I have been working on but  some sources report that it is not good for the mainspring to be wound this way, especially an old one.   Thanks, Jeffrey
    • Yeah definitely feeling some regret as I was getting to the deep innards of the watch, being careful not to inhale the smallest screws, referring to YouTube to try and figure out what I was looking at... The watch came up pretty cheap in my neighbourhood and I couldn't pass it up. I'm not sure it would justify the cost of a professional service though, so here I am
    • I have an omega triple date repair....the issue is that the month wheel is jammed and will not advance....if the date is advanced via one click of the crown it will stop at 31..the only way at this point to advance it to 01 is via the crown while setting the time...now the issue I am having at time with...getting the pressure ring case back off...for some reason on older pieces I have not had an issue...on this one yes!..any advice on how to remove it would be most welcome...there is no where on the  case back indicating where to insert a case knife....my horotec case back remover was no help in this situation either...thanks...
    • Cheers oldhippy beat me to it,  yep as old hippy says that what it does, its cheap aswell, I think I only paid a few quid for my block from cousins, you have to move the brush very fast but nice and light at the same time to get the best results, then peg out all your pivot holes.
    • Did you modify the ergonomic oiler as well? Does the oil sit on yours as it does on mine?
      I just don’t know how I could use them, perhaps for posts, touching them with the side of the oiler. The oil is going nowhere if it touch something with the tip.
