SOrry Peterburke340, this did not come through if you wanted to attach a document.

Hi all, is there any good source of Rolex service sheets? I am especially interested in GMT movements like 3186. Thanks!

thanks, I also founds this. Rolex 3035 and Rolex 3055 oiling service sheet 3035-3055-Tech.pdf

actually the cal must be 3055 as it is an old day-date with only date rapid change. still looking for service advice and ideally manual link. Thanks!

Hi, Rolex Day Date landed on my bench and I can't find any service sheets online. Would someone be able to help please? The calibre says 3035 Thanks!

Would you say this is a correct end of a mainspring for 613 movement? Seems broken but not sure how it’s suppose to look like.thanks

@JohnR725, thanks this is brilliant. I am guessing that the smaller ladies 2235 movement is fairly similar to this one? thanks

Is there the whole sheet somewhere available for download? Thanks.

Wow, what a deep discussion this developed into ) Well, upon checking the operation in different positions, I discovered that ‘crown up’ the balance wheel started to gradually slow down, I could even hear the roller touching the main plate. When I ran down the mainspring, the balance wheel had a lot of side and up down movement. So the main suspect is here to blame, shortened of balance staff’s upper pivot. That on it’s own wouldn’t make the weird reading, but I think as the roller was hitting the main plate, it produced those extra ticks. I have completely disassembled the balance and ordered new staff from eBay (£8). To be honest the hair spring has seen better days, but it is centred and doesn’t stick. I made some pics so you can have a look, will post to this thread when the new part arrives. Thank you all for your input! Sent from my iPhone using Tapatalk

Hairsping seems fine, but it may be bit old. I will check other positions, my main suspect is now the balance staff. The balance wheel seems to be doing some up and down movement, I am suspecting that the staff’s pinion is short or damaged. I slowed the balance down by moving the regulator as usual. What do you mean by ‘running timegrapher on monochrome’? It is Welshi 1900. Sent from my iPhone using Tapatalk

Hi, I’m servicing vintage Venus 203 movement, triple calendar with moonphase, and on reassembly I get this reading: it is like 4 rows of the usual read... I demagnetise again and get the same reading, then I slow down the balance and now I see this: Any clue? Thanks.

Thanks for the insight. Are there any usual problems which cause the movement to stop? At this point I am not sure what is the problem with my friend's watch, maybe it doesn't wind or it does wind but doesn't run...I will probably have a chance to take a look at it next week...

Hello my friend wants me to look at his Jeager LeCoultre Reverso, mid-size ref. 252.8.86 Does anyone here know what movements did JLC put into these simple hand wound Reversos? And is there a way to shop for parts if something needs replacing? Are there any service sheets available? I won't be able to get my hands on it for some time so that is why I'm asking... Thanks for any help.

The screwdrivers seem to be too big. This particular broken screw is 0.75mm and the smallest driver is 1.1mm http://www.moodytools.com/Moody_Tools_Screw_Extractor_and_Screwdriver.pdf

Thanks you all for the various tips. I will try them
