WONDERFUL!!!!..I added a bend to the spring as you recommended and it is working beautifully....THANKS!!

here are two photos

I did check the friction spring, it has a slight upward bend, putting pressure on the underside of heart cam, forcing it into the jewel...would you suggest removing the spring and increasing the bend?....thanks!

interesting problem with a valjoux 7730....timing well...all is good except for one item...when the upper pusher is depressed to stop the chronograph runner the hand falls...this only happens between 07:00 and 011:00....I notice that the runner is not stopped by a brake and the heart drops toward 06:00 when vertical and the upper pusher is depressed to stop the chronograph hand...the hand is tight on the runner...why does the hand fall?...thanks

excellent...thanks!

I have a question about a Rolex 1225....I am very curious about the screw just above the mounting screw for the balance cock...it seems to serve no purpose (I know I am mistaken!!) other then to spin about...it does not seem to regulate the watch nor lock the regulator arm...could you please tell me its proper use...thanks

found out that it is an AS 1315

can you please help me identify the maker of this movement and its calibre number...thanks...

sorry it took so long to get back...thank you so much for excellent foot work and advice...I'm off and running...

just came across a watch with a ronda 1219-21 movement....never worked on one before...so I'm a little confused...I read the pdf on cousins site....and ranfft.de...what is meant by "quickset by reverse setting" and "train and hand gear separately drive by the barrel"..thanks

that is an excellent point about the back lining up....thanks for taking the time to ask the omega watchmaker about this troubling job....

that is a reflection from taking the photograph..it is smooth all the way around....I considered a screw case-back...no notches to fit a tool I tried Bergeon suction grips attached to my case back remover...did not budge.....I am at a loss....

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...

I watch the video and I replaced the spring just as shown....

it appears to be coming from the minute pinion...but how...it is held by a bridge/friction washer and tied to the mainspring barrel...
