Este compa' armo un despitorre pero al final lo logró!!! This guy made a messy process but he achieved the goal!!!

[@melissasurgoft7967]

How fun!! I especially like the bubble.

[@theurbanman]

Great video Eric. Very informative and well explained.

[@y0unggilee]

Nice video as I am about to mod one myself. Quick question, I like the bubble floating and I know you mentioned the second hand is spot on, but curious to know if bubble will ever interfere with any of hands especially the second hand.

that's a very detailed tutorial, I have that same watch and can't wait to try it out. Good stuff! Also, do you think mineral oil is a good choice of oil to fill the watch?

[@EricSloferwatchreviews]

No I would not use mineral oil only silicone oil

[@armandomattiaimperatore3192]

@@EricSloferwatchreviews is it because it eats away at the plastic? I've heard people say that it can corrode plastic but I don't know if it's true

[@daddyshark702]

Thank you sir. Gonna try this with a Rangeman.

[@irreview]

Thanks for doing it in one take. Perfect demonstration video. New sub.

[@EricSloferwatchreviews]

Thanks so much for watching I appreciate you !

I've read that you're preferably supposed to use oil with single-digit cSt, or else the oil's viscosity will force the watch to work harder to move the hands, leading to a shorter battery life and worn out components. I think Sinn uses an oil with a cSt of 2 or 3. Sadly, low viscosity silicone oil seems to be really hard to find unless you're buying it by the barrel.

[@EricSloferwatchreviews]

It's working out great still so far no issue

[@Anthropomorphic]

@@EricSloferwatchreviews Cool. I've heard, fairly consistently, that the battery life can be cut down to about a third or so, depending on the oil. Really, though, a person who's comfortable hydro modding a watch can probably change a battery as well, so that's not a huge deal. Thanks for the response! Thinking about doing something like this myself with a cheap, dressier Casio.

Love your channel! What tool are you using to poke the crown stem release button. I need to buy some tools to get into what you're doing!

Bardzo dobry pomysł! Pozdrawiam z Polski! :-)

[@EricSloferwatchreviews]

dziękuję za obejrzenie mojego kanału. Doceniam cię!

[@brazilchem]

Maybe I will get the answer here : does the stopwatch go a bit slower because the viscosity of oil? Can we replace oil with water to avoid it?

[@EricSloferwatchreviews]

Water will damage the electronics the oil won't

[@brazilchem]

@@EricSloferwatchreviews Ok but oil viscosity will slow down the stopwatch. Try to swim in an oil pool to see what I mean. So I might put ethanol instead but my fear is that the time goes faster then, since ethanol is so light in density.

[@dl3691]

Would that work on a chronograph tag heuer?

[@dimpfelmoser]

Is there no danger that this oil damages the seals?

[@EricSloferwatchreviews]

I don't know it was $20 experiment

[@miversen1]

I have enjoyed your video. I did this mod on my Casio Duro. I really like the looks of the dial. It now loses time, like 10 secs per hour, and sometimes stops. Any ideas?

[@EricSloferwatchreviews]

Lighter weight oil

[@miversen1]

@@EricSloferwatchreviews Thank you for your reply. I used uMicroLubrol 50cSt oil which seems to the consensus oil of what I reviewed.

[@miversen1]

@@EricSloferwatchreviews Mystery continues, last night my duro started running at the correct rate. Tracking its run rate now, but close to normal. Running just fine at -.9 sec/day as measured today. Any ideas?

[@EricSloferwatchreviews]

That's really weird 🤔

[@miversen1]

@@EricSloferwatchreviews stopped again, reset hands and it started again. I now am thinking the hands are getting hung up. I had hoped to not have to open and re-oil.

[@ryanfrancisco22]

Does it affect on the battery life span?

[@EricSloferwatchreviews]

Yes

[@markifi]

how is the sound of these? is the tick there?

[@EricSloferwatchreviews]

Pretty much pretty much silent I can't hear a tick.

[@FiveJiggawatts]

If it gets a tiny bit cold the watch stops working. Don't do this mod. I ruined my watch At least it was cheap

[@EricSloferwatchreviews]

I put it in the freezer it kept working. Mebey your oil weight was too thick

[@FiveJiggawatts]

@@EricSloferwatchreviews I don't believe you. I used the same exact oil.
