    The hydro-mod bubble: functional or purely aesthetic?

    Is having a bubble in a hydro-mod watch functional or is it about making it obvious that one owns a liquid filled watch.
    A man wearing a watch, outside of purely social functions (where, strictly speaking, a watch is not supposed to be worn), makes it clear to everyone in his purview that they are in the presence of a man who considers his time something of value, not something to be wasted.




    A man wearing an ostentatiously expensive watch makes it clear to everyone in his purview that they are in the presence of a man who considers little.

    Re: The hydro-mod bubble: functional or purely aesthetic?

    I've hydro modded a few of my G-Shocks and I haven't noticed any oil leak on hot days on watches without a bubble. It's nice to have as a safety measure but I'm not sure if its really necessary. I'm sure that most believe that it's for functional purposes. I'm not sure if something like a 1% increase in oil volume due to high temperatures is enough to cause a watch to leak. Besides, I'm not a fan of the look with a bubble floating around.

    I once hydro modded a 5600E and it was completely functional with alarms working. And there was no bubble.
    BTW, I used olive oil and I'm not kidding

    Re: The hydro-mod bubble: functional or purely aesthetic?

    My Hydro mod is still going strong after more than 5 years - no bubble:



    The main purpose of this mod is to improve the watch's integrity under pressure. This improvement is due to the fact that the oil can not be compressed. This prevents the case from deforming under pressure.

    However, if there is a bubble in the oil, then the bubble can be compressed allowing some degree of case deformation. This diminishes some of the benefit of the mod.

    After the mod, quartz watches will generally have a theoretical depth limit of 5,000 metres. This limit is due to the fact that at that depth, the pressure transmitted by the oil to the internal components of the watch, will crush the "can" surrounding the quartz oscillator in the watch causing it to cease functioning.

    So ... no bubble is better if you want better watch integrity, but cool if you want to prove to others that you acually filled your watch with oil.

    Since I don't dive regularly, the main purpose for me to hydro mod my watches is the increase in legibility of the LCD display. The oil helps to improve display contrast, making the digits darker and easier to read. For this, the bubble isn't needed.

    Exactly, purely for better display contrast.

    Good info, thanks all 'round. I'm looking for increased legibility (and a bit of modding fun).

    The newer Casio W217 will be used for my first attempt at Hydro-modding...

    So all you do is open up the back by removing the 4 screws - immerse in a bowl of olive oil and replace the back / screws ??? Thanks p

    Yeah, I think that's the gist of it. Gotta make sure you let all air escape from the case. I plan on googling hydro-mod threads before I do it...
