Hi I already have a staking set and a roller remover on the way. How do you use the roller remover? Can´t find instruction anywhere I dont have a platax tool to remove the staff - can a staking do it? If so, how?

Hi TheFixer Well, I believe good lighting makes it easer. Despite a good sight, I feel more comfortable using loupe when a tool gets in contact with a component. Hand motion is more controllable under a loupe due to reach, which prevents slippery of chosen tool. But thats just my opinion

Hello I realized that I mostly use x6 mag?, distance 45 mm and object display 33 mm, why I now understand it makes me tired because I tilt face to check a lower level of a movement. I hear x4-5 mag is most common and therefore acquired an aplanatic bergeon loupe no. 2.5 with x4 mag. But it works at a distance around 40 mm which is near x6.7 according to attached info from CousinsUK. Seems not right? Should I buy a standard version? I want a loupe for the general screwing and unscrewing major wrist watch movement components, where I can keep the neck stretched and the screw driver away from cheek. I imagine 70-90 mm and strong enough magnification to display a movement around 35 mm.

Hi Melt: There is no ring included in the package, as far as I can see. Rogart: it's 6138-0020 Japanese model. The crystal is an aftermarket. I got it without crystal, so don't know how original looks.

Hi Does anybody know how to fit crystal on this? When I insert the crystal without the ring, it sits loose but don't know if it sit tight if I press (by dies) the ring after. Or do you fit the ring first and then press (squeeze) the crystal after? Kind regards Khan

Hi Nickelsilver Your guess is on spot. Now less depth and it runs as good as without chrono function. You made my day, thanks alot.

Hi Joe You were right. The issue was decades old stuck oil in balance top/bottom jewels, on which I had to use pegwood a couple of times. Even the caps were stuck and not easy to remove. Now it's running and keeping time well!

Hi again! Regarding chronograph runner: I managed to take the movement apart and assemble it, thanks to the knowledge shared and available. It runs like a dream without engaging the chrono. When chrono starts, it still runs good for 10-20 sec. And stops immediately. I can't see what's preventing it to run. The train wheels should be aligned enough. No lubrication in forth wheel, minute runner and sliding gear wheel. A drop of 9010 on top of chrono runner and lower pivot. It's black on the pivot shaft, is it worn out (teeth seems intact)? And should I use 9501 on the chrono and minute runner contact area? Its shown in service manual but not mentioned elsewhere here.

Hello all Thanks to all the constructive advices - I removed the pallet fork (no lubrication in the top/botton jewel, but moebius 9415 for pallet stones on the way) and installed the balance and it has the same slow swing rate. I re-cleaned the diashock jewels in isopropylalcohol (any better cleaning alternative)?. Now it´s swinging freely and much better! + - max 10 sec per day when laying down but loosing 1.5 minute per when upside down according to my clock tuner app. I think the hairspring is few degrees out of level, see attached image.

Hi Nucejoe It runs in a low beat - barely a quarter turn right/left. The impulse jewel looks intact to me. My local watchmaker couldn't see any faults by visual check. But he didn't removed the balance from movement for further analysis.

Hi Melt Yes, the train runs freely when pallet fork removed. The way I clean it is by bathing it in alcohol, lift the wheel and use a blower. I removed the diashock jewel but couldn't remove the jewel from its rear "cover", don't know the trick without it flies across the room.

Hello Thanks to helpful members here, I managed to dismantle the dial followed by servicing the movement. While final testing, I experience lack of swing in the balance wheel (as before service as well). I can't see any visual disalignments or damages. It behaves as if it was gummed up, even though power in pallet fork. Note that it runs freely when lying upside down on the bench. I'd be very thankful if someone can spot the issue. Kind regards Khan

Hello I have for a long time been excited about servicing a chronograph. Are there any cautions I should be aware of? I'm pretty much used to service different manual and automatic swiss movements. I can't find a video or manual for disassembly procedure. What movement is it familiar with?

Jberry - there seem to be a release button between 2 and 3 o'clock. Aac58 - thanks a lot for the relevant link. Looks like same setup.

Hello to you both Thanks alot - it worked! Now how do I access to the movement? Through the dial? Jdm - nothing to hide really. I like keeping the numbers private so that only the owner knows them.
