Hello I just got a lot of gasoline on my omega seamaster bond watch. I immediately put water on it but do you think there is any damage to gaskets or seals. I have tested it for waterproof and it was fine so I hope nothing got in. Any suggestions would be appreciated

No damage. Synthetic rubber (without entering the specific material which can vary) with which the gaskets are made is similar to the ones in the o-rings of a car engine. And these take hot oil, gas and their vapors for hours every day for years.

i don't think you have a problem, BUT,  be careful, gas will go where water  wont,  and the "new gas" with "various aditives and  alcohol"  can cause problems.   i have seen Honda bike carb.  o-rings disolved into a tar like goo that even acetone would not cut..

yeah.. the additives they put in petrol nowadays is pretty vicious. It turns older fuel hoses to jelly and leaves a lot of residue in the carbs if left to evaporate.

If you dive with your watch I'd suggest getting the caseback/crystal rubber and crown replaced. If you only need basic water-resistance (dishes, getting caught in the rain) then you should be ok.

The issues mentioned above with ethil alcohol are exaggerated. For one, not all countries the same amount of alchol in gasoline. Then the decay happens with prolonged exposition for certain types of rubber that are very very old and that have passed useful live already long before seeing e20 gasoline. And for a watch gasket there is absolutely nothing to worry, it may seem strange but the chemist responding to manufacturer specifications prepares a product to resist most common aggressive agents not just water. You can try yourself leave a quality watch gasket in gasoline for a week, report results here.

      AS2063 - hand setting

      By Mercurial · Posted

      The cannon pinion (be it conventional style or what you see in this movement) should slip on its arbour so the hands can be set independently without affecting the gear train.  If there is too much friction between the cannon pinion and the second wheel, turning the hands to set them backwards can sometimes force the escape wheel teeth to overrun the pallet stones, creating the behaviour you describe. The train is running in reverse when this happens.  This can often chip the pallet stones. I’d say at least half of the watches I’ve inspected with very tight cannon pinions had chipped pallet stones. Hopefully this isn’t the case with your watch.  I’m not familiar with this movement but you need to get the friction in the cannon pinion adjusted correctly.  Hope this helps, Mark

      Pallet fork was in. I’d had the movement running ok, and only removed the balance to flip it over and install the keyless works and date mechanism. The pallet fork wasn’t locking the gear train when hand setting - it was oscillating as the escape wheel rotated. This may have been in one direction only - can’t remember.

      Can someone please explain watchmaker service mark interpretation?

      By JohnR725 · Posted

      for the most part no. Each individual watchmaker and/or shop had their own system. One of the shops I worked at basically had a reference to a page number in a book. then there are some shops that do no markings at all as they keep their records on a computer and they don't have to mark the watch. Usually if somebody is marking and they've service the watch before you'll see those next to each other. then as far as anything resembling a standard goes at one time the American watch and clockmakers Institute assigned all of their members a number. but that was a very long time ago and I doubt that they are using it anymore.
