UG Tri-Compax Chronograph (centre) seconds hand can’t turn past 58.5 seconds and the whole watch stops tickingBy IOB
I have a UG Tri-Compax from the 1950s or 60s (Calibre 281): The chronograph (centre) seconds hand can’t turn past 58.5 seconds and the whole watch stops ticking/working (nothing moving/turning in the movement). However, when the reset pusher (4 o’clock) is kept pressed, it enables the seconds hand and watch to move/tick again. The reset pusher is released when the chrono seconds hand reaches 60: the watch resumes ticking and the hands move until the chrono seconds hand reaches 58.5s again. The process is repeated.
It has been noticed that if the watch is held face down then the reset pusher “procedure” doesn’t always work (i.e. the watch does not resume ticking/moving). It’s usually necessary to turn the watch over and try to press the pusher a few times in order to make the seconds hands move again.
The 30-minute sub-dial at 3 o’clock has stopped working, too.
If the chrono is not activated, then the watch seems to run properly.
What do you think is the problem?
Thanks for your insight!
I wanted to share my restoration stories that I have done for a long time and thrown into my archive. First I discussed the Atomic Mars 71 Brand using Valjoux 7734.
As it was seen, scratch and dial is broken. To begin with, I tried to brush the Case as Brushed and make it the first day. If it is decorated, I polished and re-painted the indexes (with acrylic paint). I usually do this in three layers so that the paint is not deleted in a short time.
I replaced the case buttons and tubes with aftermarket buttons.
Since the condition of the dial was in very poor condition, I had it re-painted. The quality is not so good. In Turkey, unfortunately, not doing the job well.
Caliber 7734 (Valjoux) is a special and robust mechanism for me. With good maintenance and lubrication, you can reduce deflection values up to 3-4 seconds per day. I added a short timelapse video about it :)
As a result, such a result came before us.
I want to show you my lately restoration project. This time it was a Seiko 7015-8000 with blue dial. Watch came to me in very poor condition. As you can see on photos the case was scratchty, crystal was totaly tarnished with deep scratches. Everywhere was dirt, gunk and mud...yuck. Movement was running and stopping with very low amplitude. After opened the caseback I wasn't suprised - it looked like as case - dirt and signs of wear. Rotor was loose and fall out the case. When I take off the crystall I saw dial which had faded Seiko logo, some scratches and hands which lost their lume.
Next step was strip down the movement - everywhere dirt and dry old oil. Time to cleaning bath
Look at this - it's my temporary balance wheel stand - I suspect that from temporary it will be permanent. It does job well.
After cleaning it's time to assembly movement. Now it looks better - maybe not pristine but clean and shiny. New oil here and there and movement starts to run. Now it's time for bench testing before install it to the case.
Meanwhile I took care of the case, dial and hands. Case got some polishing work - not to much cause I didn't want to loose the sharpness of edges. That is effect:
Dial and hands got new lume - I am not perfect in this work but I still learn to do this. Additional the seconds hand was repainted to orange color. I didn't change the crystall but i just polished it with waterpaper and on the end polish paste. Effect suprissed me. Time for the pleasant work - putting this all pieces together into the watch.
I started new project - Citizen 67-9119. It's seventies chronograph based on 8110A movement. Watch came to me as "fully working in great condition" As you can see there isn't crystal. The one which was here had chip and wasn't set properly in bezel so when i turned the watch it fall on the floor and broke. As you can see dial is in quite good condition, only it needs to be relumed. Hands needs to be repainted and relumed too. Movement works well but it is too speedy ( +3 min/24h). Chrono buttons work properly, only the hour counter stops at "3h" position so I must to take a look here. I striped down the watch and disassembled movement. There was some much oil everywhere so the cleaning is required.
I open this thread to archive works on Citizen 8110A Bullhead. I purchased this watch in poor condition as You can see on the photos.
Cause I have serviced few chronographs in the past I decide to try restore this watch. Maybe is not ractional from the economical aspect but we do this because we love it So let's open it.
Hands are in good condition (required repaint and relume) but the dial has broken legs and tachy scale is faded :/ I think it's really hard to find orginal and there is no gold aftermarket replacement - sad. Look at the movement.
Gosh, what a dirty place It needs good cleaning and oiling.
But the biggest problems are this.
Broken post on main spring bridge and missing rocking bar core and screw in gear train. I need to find replacement.
While I'll be working on movement the case and pushers are send to renew - putting new gold plated coat

So I fortunately found a Cyma 587 calibre movement on Ebay by chance. The lady i bought it from didnt even have a picture of the movement on her listing but the dial and hands of her watch are exactly like my Gubelin made by Cyma. And for $30 including shipping i took a chance and was lucky. The Cyma 587 wasnt one of the company's most produced calibres. I took the complete balance assembly out of the $30 junker. Staff/roller/hairspring and its stud and balance wheel. And placed that into the Gubelin watch. Using the Gubelin balance cock. So far so good. The watch is running. I used my timer and got the speed to -28 seconds a day. HOWEVER...... The balance only swings face side down or with the plates vertical. If I place the watch face side up, the balance stops. At this moment i let the watch run for 2 days. I wound it twice. Then i placed it back in its case and put it away after it lost power on day 3. While its dormant I bought a microscope. I feel the cock jewels may be amiss. Im unsure. If and when i figure out whats the issue. Ill submit an update
Here is the latest watch I’m pleased to have completed for my collection. I bought this watch in a pretty poor condition described as runs intermittently and in need of a crystal. Well, that was not very accurate. One of the dual springs was snapped, the lower Inca lyre spring was snapped and by fortune the cap stone was found in the works. That explains the intermittent running Anyway, here it is, 2 new mainspring, a new gilt ring crystal and a nice brown leather strap. I only wish it was larger in diameter.

Ok ive scoured the web as much as I possibly could and I cant figure out, what seems to me, to be a pertinent question. I see i can buy Seitz sized jewels from the supply house. So I'm assuming that the jewel press by Seitz/bergeon has reamers with OD's that correspond to their jewel OD'S. much like the bergeon bushing tool has reamers that match the bergeon bushings. They also still manufacture K&D bushings for a K&D bushing tool (or as i have it set up, my bergeon bushing tool using K&D reamers made to fit my bergeon). This leads me to my question of anyone who knows/uses the K&D inverto 18R. This staking set is also a jewel press, yes? And the reamers accompanying the staking set i would assume to be reamers for jewel insertion. Are the K&D reamers obsolete? Or is there some standard for jewel OD'S? I need to purchase a jewel pressing machine but i also wish to upgrade my staking set. And it appears that Inverto 18R would kill two birds but only if i can find jewels to match the reamers. Am I making sense with my questions and info? Thanks Steve
Hi I have attached the tech sheets for the tissot models as there seems to be a lot of parts which are common across the range. The balance complete is 720 without spring and 721 with spring attached, so by the fact it is supplied as a spare it is detachable. the spring its self does not look too bad and most probably be re curved ok. If you could supply a picture of the balance and cock laid upside down so members can see the attachment it would be a great help. cheers 2790_Tissot 781.1,782.1,783.1,784.1 (4).pdf 2789_Tissot 781,782,783,784 (2).pdf 2791_Tissot 783.2,784.2 (1).pdf
