Ingersoll Triumph Mainspring problem

Hello all,

A friend sent me an old Ingersoll Triumph wristwatch to repair. I think I found the problem pretty quickly but someone had tried to lubricate it with WD40 so I decided to strip it and service it.

No problems until it came to the mainspring barrel. I don't have much experience of these types of movements and I can't say I have come across this type of arrangement before. Simply put, I can't remove the barrel at all. The screw keeps turning, with it the barrel and the ratchet wheel. I cannot work out what to do and would be humbly very grateful for any advice. 

I have attached some photos to illustrate the thing.

Thanks in advance

you can service the main spring and leave the barrel attached to the plate. it looks like the cover will lift off.  vinn 

If the ratchet screw and wheel are not removed, the barrel arbor cannot be lubricated to the plate. Not a good idea.

Hold the barrel just like one would do with a nut and bolt.


Thanks for your replies but I have been struggling to do that. I am scared of damaging the barrel if I hold it too tight. The screw won't budge.

alert !  that screw is usually LEFT HAND THREAD  most often broken,  even by good  mechanics.   THAT,S  why i suggested leave it  and service the main spring and lube under the screw.      if you break the screw - you are screwed,  cheers vinn

Nick;  on a watch,  it is hard to determine "if it's left handed"  unless you are told or find it in print.  it takes so little tourque to brake it.  if you are lucky,  only half the head brakes off and then it can be turned with plyers ( the other direction).  vinn

It's not hard. The threading is so the screw doesn't get lose with the rotation of the wheel below it. For a ratchet wheel, observe the direction when winding.

      I've bought brands like Citizen, Seiko, Titoni, Tissot, Roamer. Strange thing is many of them were using ST96 movements. I'm not sure if the ST96 is original to that model or whether it was a replacement movement.  All the watches with nice looking dials were obviously refurbished, after-market dials. And all of them had over-polished watchcases. Some of them had non-original hairsprings, rejewelled pallet forks, watch crystals that don't fit and glued in with a generous amount of glue. One of them was totally not working because the pallet jewel was loose to the point that it almost fell off. But the sellers were very nice. The seller of the non-working watch gave me a complete refund. Some of them gave partial refunds. I would say don't by luxury watches on the internet, regardless of the country the seller is from. Don't believe the "serviced by master watchmaker" statement. Have realistic expectations. ( Do expect the occasional complete junk.) Do expect to do a complete overhaul and major repairs. Otherwise, watches from Mumbai are great. For clocks.... I'm not so sure.

      Regulating an F6922 without a timegrapher

      By WpgRob · Posted

      In 2020,I picked up an Orient Mako II online. It ran at +15 seconds per day and after 3 years of resets more than weekly, it was time to crack the seal and take a shot at regulating it. Not having a timegrapher, I used a spreadsheet to track the time, referenced the Canadian NRC website, wore the watch between adjustments, and used the back end of some tweezers to lightly tap the regulator daily until it ran to within one second per day.   Two months later, it’s still running to within 1 second per day when measured over a week or longer, while daily variations are up to 9 seconds per day. For my purposes, its overall stability is surprisingly good. Is this method of adjustment “better” than adjusting to 5 positions using a timegrapher, since during the adjustment period the watch is already in the environment in which it’ll be used?

      @HectorLooi Yes, I would say that Mumbai has the highest liquidity in terms used watches. How was your experience with these used watches and what watch brands did you buy used? I have always found the vintage luxury watch segment in India a bit shady. Quite a few are genuine watches with genuine matching parts but just not from the same one.
