As someone who takes the view that if it's been assembled, it can be dissembled and therefore fixed, I make occasional forays into clocks and watches and have a reasonable set of tools.  I've practised on a few Chinese movements for the skill building and entertainment, but I confess I wouldn't take any of my 'real' watches apart - off to the professional for those. I'm more likely to tackle a clock due to the scale.

Strong preference for mechanical, although - putting chronometer definition aside - possibly my most 'accurate' watch is a Bulova Accutron, which I have rated down to around half a second a day over two months.

Built an interesting rating circuit based on the usual piezo element, but not sure i'm willing to open a very good watch to do the adjusting!

I do get a string of more modest value watches for inevitable battery and/or gasket replacement, case polishing and other minor fettling and maintenance.

So, an enthusiastic amateur.

OK R. Yes a man has to know his limitations. We all have to know this. You are doing OK. Watch Mark Lovick and you will learn a great deal. He is extremely knowledgeable and supplies info and courses. I am 75 now so a bit old. Yes, you can easily design a watch timer but need software for different beat timings. Hardly worth the trouble. For us amateurs I recommend a Timegrapher 1000 or 1900. The 1900 I believe supports co-axial escapements but I am not sure, never had one to try. They are cheap. 1000 £118. 1900 £147. I timed another Seamaster 300 yesterday and had to take great care with the screwdriver. (micro adj). This watch had an iso beat adjustment and this was a real help as the beat error as 2.2. After adjustment I settled for 0.02 beat error in 3 positions. The watch was of 1971 manufacture. I averaged + 8 Sec`s a day for timing. Regards, Mike.

Hi RJK, Your Bulova Accutron was the best tuning fork watch.  I had an Omega F300 (not as good as the Bulova)  I smashed it many years ago when a car pulled out and knocked me of my motorcycle. I escaped with hardly a scratch. Watch and bike were wrecked !!. Speak later.

      Epilame / Fixodrop

      By VWatchie · Posted

      Sounds great! And yes, I would use grease for the keyless as well although treating the parts with epilame would make the grease less likely to spread in the long run. Not critical but won’t hurt. My current strategy is to epilame treat all parts getting in contact with oil or grease.

      Epilame / Fixodrop

      By Knebo · Posted

      Hello everyone, for what it's worth, here is my approach: 1. Escape wheel submerged in Epilame, then dried quickly with a hairdryer. Then the final tip of the pivots are cleaned by poking into pithwood. The logic being that the Epilame is removed at the intended contact point (to avoid any residue that may mix with the oil), but remains in the areas where oil is not supposed to spread to (further down the pivot towards the wheel). The escape wheel teeth also benefit from having Epilame to keep the 9415 in place.  2. I use a syringe to treat only the pallet stones. I suspend the pallet fork with some Rodico so that the stones hang downwards. I notably use a rather thick needle where a drop WON'T form, but rather where the Epilame liquid stays in the needle tip, which I then dip into the pallet stones. It requires some practice to get the right amount of Epilame into the needle tip, but it works for me now. This way, no drop will "jump" onto the pallet fork and potentially go all the way to the pivots.  3. I let the movement run for a few minutes without lubricating the pallet stones... to scrape off the Epilame in the intended contact "channel". Then I remove the balance again and lubricate the exit pallet stone with 3-4 successive drops. See the "channel" that forms on the pallet stone in the picture -- not so easy to see, but it's visible.       I am conflicted about the use of Epliame in balance jewel settings. My impression is that the two jewels sufficiently suspend the oil (even 9010). Apparently Rolex recommends NOT to use Epliame there (heard from a former Rolex service center watchmaker), as it could cause additional wear. Apart from that, I follow specific instructions where I can find them. E.g. the infamous Rolex reverser wheels or sometimes (parts of) the seconds wheel. Exception: I'm currently servicing an Eta 2824 and will probably ignore the service sheet that recommends treating the whole keyless works with Epilame and then using HP1300... I'll skip the Epilame and use 9504 grease.

      I'm going to give this a try today/tomorrow on my UTC33/Seiko 66, thanks!

      Don't forget Mark is a hard working watch maker so he is also tied up with work. I'm sure he is keeping his eye on this forum making sure it is running along nicely.
