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...

I am having such a bad time with a Rolex 2030...I have completely serviced the movement...adjusted the cannon pinion to proper tension...however it takes the minute hand approximately one minute to "catch-up"...I set the hands and about 40 seconds later the minute hand starts moving..on the timer all looks good...if I take a piece of peg-wood and touch the minute hand there is a little play in it before it holds fast so it is not a cannon pinion issue...what on earth is the problems!

I am not familiar with a secondary cannon pinion...just the one in the photo....is that the one you are referring to as secondary?...since that is the one in need and have only found one listed with that R attached to the part number...thanks

I have a question about a ladies Rolex 2030 I am working on....I am in need of a cannon pinion...however I noticed two choices...the 4457 and the 4457R...would someone be kind enough to tell me the difference between the two...thanks..

thank you all so much...a 1010 it is....i can't believe i missed the number when looking in the train bridge depression...thank you again

would someone please help me identify this omega movement...i need to replace the stem and crown...i pulled the balance cock...still not movement numver....thanks...

I can't seem to figure how to open the case-back to access the movement...thanks..
