I got a replica rolex 3235 movement, a complete clone as far as I can see with me. Used for a submariner homage project I embarked on. 2 Months in, when I took the hands out for a polish and cleaned the dial, after I had replaced the hands and recased, the minute hand and hour hand started to intermittently stop and lag behind. The second hand was perfectly running at a nice -5 seconds a day. I took it apart for an inspection, nothing looked broken in the gear train, and the timegrapher numbers were still excellent, but realised that the hands would shift extremely easily when pushed. I never took notice whether that was normal or not, but based on my suspicion and a little extra research I concluded that the canon pinion was loose on the center wheel arbor, So here is the issue, there are no known 'good' watchmakers in Singapore that will work on this replica movement, and its quite difficult to find parts, unless I swap it out with a genuine canon pinion. I've heard of a cheap way to tighten it using a shaved down blunt nail clipper, but would like to know. How 'tight' is tight, when I push the hands while the crown is in the hand-setting position, am I able to push it? will it require alot of force? or just not move at all without breaking it? Is the friction-fit canon pinion just supposed to be tight enough that when the setting gears are tucked away, the centre wheel can continue to power the watch? and while the second hand is hacked, there enough slip that the hand can be set by the crown? Are there any other options to repair it? Im still a student so a cheap option of repair would be nice. Thank you all for reading.
Cheers mates!! Have just put togheter a Lemania 3000 – Hand wound, small seconds. And see that it gain 2 hour on a period on 12 hour. This looks like some canon pinion problem to me or?? Only probleme with this is that I did not take apart the canon pinion and the center wheel, I thought I just let i be in the movment when I cleaned it. I usually let the parts spinn in white spirit for ten minutes (turpentine substitute, petroleum spirits, solvent naphtha (petroleum) Then I spinn for 10 minutes in methylated spirit Then I finish with a 1 minut spinn in isopropyl alcohol After that I did lubricate on all the places needed to be exept the canon pinion... I hva looked at the balance spring, and it seems okay, its difficult to say. How to regulate this also? What is A and what is R on the balance wheel bridge? Pls help me when I still have some hair on my head !!!!
Just recently i have been rather busy with a large intake of repairs & servicing, i figured since ive worked so hard ( and yet still have more to do ) id treat myself to another tool. I know i don't really need it but i do like Bergeon tools and this one i picked up is in mint condition with original box. I normally use my Bergeon staking set but this will make a nice addition to my growing collection. Sad that a new tool makes me excited, or are you guys like me ? Next on my list is the Bergeon hairspring collet tightening tool :) Hopefully i should have some nice watch photos to upload over the coming weeks as i have had an Omega repair frenzy including a rather battered Omega RAF 1953 Cal 283 and also a return of a personal favourite 1956/58 Seamaster, and not forgetting a complete restoration of a Tudor Oyster Princess :D
Some of you may remember the little tool that I made that enabled be to screw in the mean-time screws of an IWC Cal 64T movement that was losing 10 minutes per day. Well with the screws fully in (3 turns per screw) the movement was still running very slow. After more cleaning of the hairspring and undercutting a pair of balance screws by the amount that corresponded to the thickness of a timing washer that would produce a change of 5 minutes per day (when added) ... it was still running slow by 5 minutes per day. Back to shoveling snow and wondering if I should simply remove two balance screws, then enlightenment. The canon pinion might be slipping. With a tightened canon pinion the movement now runs fast, and with a pair of normal length balance screws to replace the undercut ones I am within the range of the regulator. My theory is that because of a stiff spot during the hour wheel turn the canon pinion slipped just a little every hour and this could explain why the regular loss of 10 then 5 minutes per day was so reproducible. Any better explanation?
