Water in case of Omega Seamaster - Valjoux 7750

Question

Hi all,

 

Six months ago I finally took by hobby to the next level and was able to service my Omega Seamaster Professional, valjoux 7750 based movement.

 

I did invest quite a lot on learning how to service the movement and get the right tools and lubrification, and this went very well. The movement is performing over 300° and with zero beat error.

 

But I did not invest on getting the right tools for case closing and water proof test and, as a result, after washing my watch under the tap a couple of days ago I was surprised a couple of hours later with some humidity inside the crystal.

 

I opened the watch straight away and cleaned some small traces of water on the dial and crystal.

 

Question to the group: given that it seemed to be a very small amount of water which I'm not able to find any traces now, would it be enought to leave the watch outside the case for a couple of days to dry out? Or just get to it and make a full service again?

 

Many thanks 6662df8a8c72ea2c0c56482392c16190.jpge775fd7b72b4491195fdf90213e247a3.jpgcfb9ef1c6bcfd7b9a0026ffd3b1b4eab.jpg

It's an Omega with a chronometer grade 7750. There's no damage to the dial, so you're very lucky you caught the moisture and opened it in time. I strongly suggest you take it apart and service again to avoid possible rust, heartache, pain, and $$$ later on.

I agree with J,  furthure, I place the backside of the dial under direct sunlight ( under cover) for a day, dial shows no sign of moisture damage Now, moisture penetrates through pores in the paint, flakes appear much later.  What luminious material is used on hands ?    The sooner you clean the movement the better. 

Shock breakes a part or two, water ruins all.  Regards

TAG HEUER care and caseback seal info.txt

My son had a similar problem with his TagH. I found the attached (copied to txt format) on the TH site. Obviously the amount of condensation is relevant.  I had a similar event with my Omega Seamaster (cal552), I removed the back immediately and left it next to the hot water storage tank for a few hours to warm up and dry out.  I left it on some pieces of cigarette paper (to absorb any damp air) in a large plastic container (to keep out any dirt) and replaced back when fully dry.  Not had any problems, corrosion or otherwise since.

    • It has 'Vaillant a Paria' on the chapter ring I did a search in Goggle and he made high end clocks, one sold for 600,000 at auction and a few others 20,000+ he is also listed in Loomes book. That is why I do not understand the error in the movement. I looked at some of his movements on other clocks and they look the same, however most key holes are in the right place. I think I will contact a high end seller that has one of his clocks for sale to ask if this was one of his, hope I get a reply.
    • Cousinsuk have there own size chart. Which i think is the best. Esslinger have the right one that most other use. U should need a tap 8 crown. As for the crown. older Tissot used a domed crown without logo.    Watch Stem Tap Chart _ mm Size Reference Chart _ Esslinger.com _ Esslinger Watchmaker Supplies Blog.html
    • I get it....and I honestly dont blame them. However theres much more to the story primaruly shitty customer service. The bottom line the price between a tag aquaracer and the Oris TT1 is $0. The reason why I went with the TT1 was its smaller size. With that said this saga has taught me a couple things.......Oris uses a cheaper grade movement and their quality is much less than the TAG do youre better iff with the TAG in the end. For me back then I had no concept of movements etc etc and though each watch manf made everything in house. Had I known then what I know now I wouldnt have purchased the TT1. Hopefully anybody in that same situation may stumble upon this thread and be warned as I was not. Sent from my SM-G950U using Tapatalk
    • Not surprisingly, an ETA 2824-2. https://www.atlantic-watches.ch/en/shop/retro-vintage/worldmaster-original/2355/worldmaster-original?c=80 But a price of RON 125,  or €26 seems too good to be true.
    • What is an "adjustable escapement"? Even the cheapest mov.t can be rate regulated, while adjustment is a sort of obscure art which if you ask about,  you will be told that "starts at the mainspring". Whatever that means
