I have just bought 250ml of Priory Polish Watch and clock cleaning fluid after reading good things on here about it. I have just been doing a Seiko 6119 and found it really difficult to shift the old oils etc. There was a greenish crud that was everywhere and it did not want to budge, it took me several goes with my usual degreaser and then lighter fluid to get it off. So I thought I would give some Priory a go on my next victim. I am using a small ultrasonic cleaner at the moment with various baskets and cages for the parts. I was wondering whether it would be ok to dilute the PP cleaner with hottish water, and if there would be any advantage in doing so.  It also says that the fluid can be reused, what are your thoughts on this? I can see how I might use some again to clean the dirtier parts such as the barrel and spring etc but I would be reluctant to put other smaller part into old fluid.

Hi Davey, I dilute the cleaner one part cleaner to seven parts water and put it in a jam jars with a screw top.

First give the parts a rinse in lighter fluid to take off the worst of the grease and oil.

Now place the parts to be cleaned in the jar with the diluted cleaner, and place the jar in the ultrasonic cleaner which has been filled with water at 50C. The parts are then blasted for around five minutes, or as long as it takes to clean them.

I tried out the cleaner a couple of days ago on some parts that I thought were "clean". There was some green debris left in the gear wheels that were stopping the watch from running so I stripped them out again and gave them the Priory treatment. Fantastic results!   I feel as though I have been wasting my time with the other stuff.

Converted now.

 

By the way, I used it as advised here and put some into a small jar containing the parts and plopped it into my small ultrasonic and it is a great method and economical with the cleaner too. Would it be less effective if used in a slightly heavier walled jar or container, would the ultrasonic effect be diminished a bit?

From what I understand glass doesn't interfere with the cavitation process in an ultrasound so thickness shouldn't make a difference. The less solid the container (for example I have heard of people using solutions in plastic bags) the more the interference. It will still work, but not as well as in a glass jar or just straight in the tank. I just use different size glass jars.

      Most all my 404 candidates are coming from swap meets and "antiques fairs". One more $4US plus battery and elbow grease. Unnamed digital on a decent ss bracelet. Gains 10 seconds a day so not that accurate...

      I voted.for the 6.99 assuming £, which works out to $8.74US at the current exchange rate.

      £4.04 originally worked out to $5, or thereabouts accounting for currency fluctuations. Inflation calculator from 2020 (when the thread was started, though not when Andy coined the term) says we're looking at $6 currently. What currency is the 6.99 inflation adjusted figure cited in the poll? $6 may still seem restrictive, but don't forget that's part of the point. It's a challenge. Thrill of the hunt and all. Diamonds in the rough. Also, and my personal angle on the game, a fun and inexpensive way to learn watchmaking skills.

      ETA 9362 check electronic module

      By Cmmb8519 · Posted

      Dear all My first experience servicing a quartz watch after servicing as an hobby my mechanic watches for many years. This is an old Certina that was given to me by a friend, with  a ETA/ESA 9362 movement. Before service I put a new battery and the watch was working. After servicing the movement stopped working. i understand that there might be a lot of reasons for this (including the fact that I used technics and oils from mechanic movements on this one  ), but at this stage I would only need to check if the electronic module is good. Don't have a quartz tester but only a multimeter. You will see on the photos that the battery contact is broken and needs soldering. With the battery in the movement I can confirm that the electronic module had power (1.57v). Question: what basic tests can I do with a multimeter to confirm that the electronic module is good? how to check if the coil is good and if there is pulse in the electronic module? what contacts should I use to test it? (I saw some videos on you tube but was not able to find the specific test procedures for the ETA 9362). Any information to help me check if the reason for the movement to stop is on the electronic or mechanic part of the watch is much appreciated. Many thanks
