Tag Heuer Aquaracer with SELLITA SW 200 Movement Autowinder issues

Hi all

I need some advice with a TAG Heuer Aquaracer watch that has issues with the autowinding mechanism.  Its fitted with a SELLITA SW 200 movement

This is one of those doing a favour for someone that is turning out to be a bit of a nightmare.  This is the one that the seconds hand fell off its pipe when I first stripped it down.

When the watch came in the auto winging mech did not function, it was doing the common helicopering of the rotor when hand wound and would not auto wind.

I stripped the autowind module, cleaned it and lubricated the reversing wheel with the recommended Lubeta v105 and once reassembled it no longer did its impression of a helicopter so job done I thought, but no it still does not autowind if you look at the hastily recorded video below you will see that there appears no connection between the final gear in the autowinding module and the Ratchet wheel but both look to be in good condition, so I am a little lost in finding the problem.  

Sorry for the poor quality video but can anyone see anything obviously wrong 

It appears that the petals on the pinion are not meshing with the teeth on the ratchet wheel, but to my eyes they don't look damaged or worn. 

Anyone got any thoughts on this

That‘s how I see it too! The video is great!

The only possible cause left is the wheel or pinion being loose on the arbour. It seems to be a circular witness mark there.

Well spotted, that was exactly what the problem was

A few careful hammer blows and my staking set soon tightened it up enough to now work.

Did I mention this movement was cursed.

Put the Auto wind bridge back on the movement and confirmed that the autowind will now work started to refit the rotor and suddenly the screw went loose first thought was (dam it) or words to that effect I have broke the screw but no if only it was that simple

The screw goes into a threaded collar on the A/W bridge and that had broken off. 🤬🤬🤬🤬

Fortunately Cousins have them and they are not too expensive. and I will order a new wheel as well just to be safe.

Don't think I will ever touch another TAG again. GRRRRRRRRRRR

And to cap it all the repair I did to the second hand which popped off its tube when I removed the hands didn't hold so I have got to replace that as well and the only ones I can find are £110 a set GRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR

Did I say I am never going to touch a TAG again

Yikes! I feel your pain. Some watches are just like that, aren't they? Live and learn. Sellita 200 huh?  Thanks for the warning. Good luck completing it and seeing it off...forever. Cheers.

      Help with Hermle ships clock

      By watchweasol · Posted

      Hi Mike I did a ships clock a long while ago, not a Hermle though and without getting the beast in my hands to refresh my memory I can’t recall the timing.  This doesn’t help I know but will start the grey matter turning.

      Of course it will continue Richard.

      Help with Hermle ships clock

      By Rixy · Posted

      I have stripped and cleaned a Hermle ships clock. It was just oily, no major faults, and I reassembled it, following my photos in reverse order. The time train is fine but the strike train will not play the ships bell strike for half-past. Ships bells play a four hour sequence for the 'watches' and play double 'ding' for the hour and the double dings plus one for the half past (eg half past the second hour is 'ding-ding' 'ding-ding' 'ding'). Sounds complicated but it isn't really. The strike wheel consists of pairs of bumps (for the ding-ding) and no single bumps. There must me some mechanism on the half-past that lifts the strike lever over one of the bumps so only one ding is played. When I get to a half past, it still plays double ding. I have a feeling it is to do with the lever in front of the rack (there is a sprung attachment  on it) and the position of the wheel (to the right) with the two pins that lets that lever fall, but no matter where I place that wheel I cannot get a single ding at half past! Please can someone help with advice on positioning so I can fix this? BTW Happy Easter 🐣

      No it's not 52. I had looked at the Pocket Watch lift angles thread, which lists Elgin 6s as something really high like 62° but visually that is not at all what this watch is doing. I think 42° is more correct and that's where my machine is setup. The watch has a million problems but I have made solid progress. Impulse jewel replaced. Hairspring didn't match the balance (which also doesn't match the serial) but I got it down into range this weekend with 8 or 10 huge timing washers. Replaced the mainspring, balance and train are nice and free. At this point it is running consistently and in beat at about 160°, the third wheel has a bend that sends the timegrapher on a little roller coaster every 8 minutes or so. Remaining amplitude problems may be down to the escapement. The banking pins were way out and it didn't run at all before I started. It has one of the old brass escape wheels rather than steel, and I assume the faces its teeth are probably worn or scored in a way I can't yet fix (or see without a microscope). I know this watch is not going to run above 250° but I am going to keep trying to get above 200. But the best part about this watch? Some unscrupulous person stamped "21 JEWELS" on the train bridge sometime in the past, right on top of the Damascening. It's a 15 jewel movement.

      I think it would rather be the blast of high current drain that would do the damage. But if used occasionally to maybe fix a mainspring or do dial feet it might be worth trying especially if the mainspring or a replacement couldn’t be found.    Tom
