    Oil filled Casio!

    Now I have seen it all. Wonder what oil he used, Hope it was extra virgin!

    I think it was Vinstink who did a Gshock oil filled a few years ago. A bit of a laugh as I remember and was a bit different. I bought it off him at the time and flipped it. I can’t find the thread at the moment...

    That bubble bit messy and think there’s ways around it.

    £75 for a £15 watch (Argos) with a big bubble in it. Hmmm, let me think about whether I'll bid!

    I think ‘Cilla might have done this in the past too.

    I've seen this done a few times on here but I'm pretty sure it was always a digital Casio like the F91W. The reason being that analogue quartz movements don't generate a lot of torque, so will have trouble moving the hands through a viscous liquid like olive oil. If this works now, it probably won't for very long.

    Someone here did a Seamaster. I'm sure Huertecilla did a F91-W as commented above. There are a few DIY examples knocking around the WWW. But some manufacturers offer oil-filled analogue quartz watches; don't know if they have strengthened movements but I wouldn't have thought so.

    DIYers might use olive oil but the liquid used by Sinn and others isn't a viscous oil (not really an oil at all) but liquid with viscosity similar to water.

    Rings a bell. Was that olive oil or Fluorinert though? The latter is what Sinn use and AFAIK it is much less viscous than oil. It's also what was used in that CW example above.

    Yes, but this particular example uses olive oil. Edit: just re-read the eBay listing and it says "oil" but isn't specific about which type of oil. It might be old chip fat.

    This example might but your post was in a more general sense about what has been done on TZ.

    Ah yes, apologies. Re-reading what I actually said I wasn't clear enough that I meant filled with oil (like the eBay watch), as opposed to Fluorinert. I'm not sure anyone on here has tried filling an analogue watch with oil.

    What's the big deal, he just added a bubble level complication.

    Have a silicone oil filled g-shock. It needs a bubble for pressure differences. The dial looks great. Makes the solar panel stand out.

    "Complication" - I like that

    I guess he wanted to build and sell a poor man's Sinn. Except it's the wrong kind of watch with possibly the wrong kind of oil. I do wonder how it affects timekeeping on an analogue watch.

    Even if the oil is very thin, moving the hands through it must kill battery life. And then it's a messy job to change the battery also. Why?

    A couple of reasons, legibility, you can read the hands from any angle as the crystal doesn't reflect / refract when there is oil up against it from the inside, the other one is depth rating, the oil makes the watch incompressible. The Sinn UX Hydro is a great example of this.

    I did this a few years back and put it to the test at depth. I just wish I sent a stock control Casio down with it too...

    This is a process offered by a few compadies for sale over the years, Sinn, Beuchat and Bell and Ross spring to mind, all of which offered analogue watches with decent battery life.
    The relative incompressibility of oil means that almost limitless WR can be achieved in a case with little or no inherent strength. By somparison, having air inside a watch absolutely requires strngth to resist the compressive forces at depth.
    Several people here and elsewhere have done their own versions, including Richard Askham who did a Zodiac, a Seiko Sumo and others.
    People have filled with Flourinert, Olive oil, brake fluid and a few other things besides.
    One guy did it to 2 Omega Seamasters.
    I do not have the skill to do it myself, but wanted to see a PRS18-Q done with it.

    Thanks for answering, I was vaguely aware of that. My question why however referred to a 15 quid battery powered Casio, not an expensive piece of specialised kit.
