You can actually see the air bubble under the movement holder both times i put the case back on. Be patient, on camera it's a little hard to see, but if you see that bubble, get it out! Cheers 😁👍
I'm a new MDV106-1 owner. Is there oil in the watch when you buy it originally? What's the purpose of the oil? Will the water resistance remain at 200M? Have you ever replaced the original crystal with a sapphire one?
This modification will significantly reduce battery life. It will reduce it to one year because these are low torque movements, and requires more power to move through the oils as stated in many comments below. Know this before performing this modification.
Hello, Great video, I wanted to give you and your viewers a tip on a better more complete fill method...use a small wide shallow bowl just deeper than the thickness of your watch, fill the bowl with the liquid silicone and submerge opened watch allowing the silicone to completely fill watch , then while watch is still completely submerged in silicone submerge the case back and allow it to completely fill with silicone and assemble watch back wile both pieces are completely submerged. this method allows for a truly complete fill of your watch with zero bubbles. Cheers!
Thank you for resisting the RU-vidr urge of imposing some crappy music background! An amazing demo of this vintage mod. In the old days, folk use to use vacuum machines and all sorts to ensure a no bubble finish. You demonstrated that all you need is an abundance of oil some patience to let it settle, and an amazing finish, well done sir.
Really great video, buddy! Really cool result and love the fact that it takes away ant reflections and makes the watch more legible. It makes it look a bit more premium in fact. Happy Easter and stay safe!❤️
Great tutorial, thanks for sharing. Is there any risk of oil leaking out through the crown when it's unscrewed and pulled out to adjust the date or time? Just asking cuz I know you're never supposed to pull out the crown while underwater. Thanks
There are two advantages. First you get an almost infinite water resistance. No water can get in because oil is denser than air and fills the watch so no water can get in even if the case leaks. Pressure outside is pressure inside. The second advantage is much better readability under water. Air breaks light different than liquid resulting in a mirror effect under water if the watching angle is below about 60°. Oil filled watches show the time even if the angle is very narrow.
I recommend doing this in a small plastic container. Something wide enough to manipulate the crown, and tall enough to stand the case back up in, plus half an inch. You flood the whole thing, minus a quarter inch.
This a great tutorial and help. Does this cause any problems with the watch movement, or anything else concerning? Also, does the oil come out if you have unscrew the crown to adjust time or for other reasons? I'm assuming that you will have to refill with oil every time you change the battery? Thanks for your help and guidance.
Excellent, thanks Aaron so much for showing us how to to the hydro mod, I’ll have to dig through the safe and see if I have a suitable watch, damn Covid stay home boredom.
Nice, I’m glad I and others have some influence in your videos, but I have two questions. #1 can I use KY jelly instead, because I have a shit lot left over from my productive years. #2 what the heck do I do when the battery takes a crap?
Hey be warned guys. Don't use Super Lube O-Ring Silicone Oil. Almost killed a watch, but noticed the viscosity is crazy high (5000 cst). The oil recommended by most is only 50cst 🙃
Dude!!! I've tried this mod on 2 other analogue Quartz and looks absolute stunning but! The hands would no longer move!! I asked a watch guy why and after him questioning me like I was a Russian spy for why on earth I would want to do it and me babbling like a child who has been caught pissing in the fridge...he finally said.." it is proberbly due to the hands being friction fit and so the oil has taken the ability to allow friction to be present" Oh! What is your thought and does this make only the Duro suitable for his mod?
@@kennethmelsen dude.....don't it just grind!!!!! Only option now is to flush the modual thoroughly in lighter fuel...and likewise the case.....the case then can be given a good wash with dish soap dried and polished.....the movement will need to be out in a pot big enought to be able to fill with lighter fuel and the movement to be wibble wobbled in... Remove repeat in clean fuel in another pot...more wibble wobble... Lastly remove movement and squirt with clean fuel and allow to drain and dry.... Should it be needed a couple of passes of the old ladies hairdryer...... Job done....seems a bulls ache but tried and tested and has got me out or more than one failed hydro failure. Hope this helps.
Good video. I can't tell much difference on camera. I have the black and the blue versions of this watch and maybe will pick up the black and gold at some point. I wonder if you have considered a sapphire dome crystal mod as a diy or if that's possible.
Other than enhanced dial contrast and slightly better anti reflex effect... The cons outweight the pros and this mod does not really make sence. Imagine shattering the glass by accident. You don't only get the glass shards, but also oil spill. Reduced battery life, true. Need to refill and all the unnecessary mess related to refilling or battery change. Best mods for MDV-106 are getting proper lume on indexes and getting it on a prefferably dedicated bracelet from casio. No need for hydromod which is more of a disaster rather than mod. Not to mention, the struggle if you ever want to get rid of that oil...
I own 2 MDV-106s although I never did a hydromod (and never will). Anyway... My speculation would be the hydromod might cause some decrease in accuracy. One thing's for sure, it severely decreases battery life.
@OFD Do you have a link or model name to the bracelet you have on your wrist in the video? That is another duro, right? Your bracelet doesn't have any gaps, looks really nice!
Looks like a Tudor to me, so it’ll be a flip-flop Rolex imitation. Probably the reason why he’s rubbishing his three Duro’s. He’s obviously an enthusiast, looking for subscribers, but hey, if he can afford a Tudor, he can probably afford to replace the Duro’s he’s just messed up.
In this case it's only some better dial contrast and some anti-reflex effect. But in this case the cons massively outweight the pros. Just look at all that mess... Dereased battery life. Pssible accuracy issues. What if the glass shatters? Glass shards + oil spill. Refilling itself during service. And what if you ever want to get rid of that oil? Imagine cleaning that.
Great video.I would prefer the bubble but not a big one.Neat to see it expand/contract.How does it affect the longevity of the battery? Do you take orders? I want it done to one of my light powered watches.Or my Marlin.
Thanks for tuning in. I'm going to be monitoring battery life. Only thing i could think is the fluid causing drag decreasing battery life, but this is just a guess? I don't take orders or do these for sale. Just something i wanted to try. All 3 watches are running perfectly still after these mods. No loss of time at all.
Hi, I have copied your idea and have made my Cooper Submaster a hydro diver watch. It was already 300 meters, but now I will be 3000?? ;) Thanks for sharing. Great job!
I did this with the watch fully submerged in oil to eliminate air bubbles. I have noticed the crystal being cockeyed. I wonder if screwing down the case back pushed the crystal up a bit. It doesn’t leak oil. At least not yet. I guess I’ll see if the crystal stays put or flys off in a few days/weeks.
Yeah, liquid doesn't compress. I crack the stem when screwing to let excess oil out, if you do it without submerging the case, do it with the crown at top most position.
Just drill a few more small holes in the plastic movement holder for air to escape through. Problem solved. I am going to try blue dyed oil in a Batman Duro.
Not a fan, but it is a cool concept. What's inside the quartz cylinder? Air or is it a vacuum? What's the theoretical pressure resistance? Good vid. Thanks.
Actually a great question. I'm not really sure. They are using a Myota movement of unknown caliber. I could see that as a possible weak point under extreme pressure. WatchChris on RU-vid had a non screw down crown, 100m Casio that was "tested" to 1000m without issue (test was performed by a non professional watch guy). I wish i could test and verify. Thanks for tuning in and making me think a bit😁👍 Cheers!!
Supposed to increase water resistance and makes the crystal have no glare, and very visible at extreme angles. It wears out the battery much quicker though. Thanks for tuning in 😎👍
Are they still running fine after months? I've also read that the silicone oil makes the lume material turn a little yellow, has that shown any signs of happening on your Duros?
Yeah as you can see while he's modding the watch, the black duro seconds hand on the upper right corner struggle to move at some point during the videos. It might affect with is accuracy.
It's to the second on my atomic clock for the last two weeks. It moves much smoother through the oil, but never struggles to move. I'll track the battery life, which may be reduced by the additional torque required to move through the oil. I'll make an update video if the timing goes whacky, but so far the blue and black are keeping perfect time.
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?
The oil is viscous and creates drag on the movement, left in a car overnight in winter I bet it would stop all together. A neat bit of tinkering anyway.
Yeah, buy yourself a new Duro, throw the other in the bin and live with the feeling of regret every time you look at the new one. If you’re not a deep sea diver, this is the stupidest ‘mod’ to undertake with your watch. So Dumb.
Thanks David!! It's really impressive in the water. It compared it to my Steihart V1 OVM in a pool this morning. The Domed sapphire crystal on the Steinhart mirrored out quickly at a slight angle. The MDV wasn't even an issue at extreme angles under water. Thank you for tuning in!😁👍
I wonder how much weight did it add? I would like to try this, but I envision oil gushing out at the worst possible moment. Who am I kidding. Of course I am going to try this. Thanks for the tutorial, and wear those beauty's in health!
Debería usted de haber calentado el aceite primero antes de ponerlo dentro del reloj.El motivo es que cuando el aceite se calienta se expande,por lo tanto usted ha calculado la medida de llenado en frío.Cuando a ese reloj le dé el sol en un día de playa cualquiera el volumen del aceite aumentará hasta romper el cristal.
I don’t really feel comfortable when you mess around with the inside of a watch. I still don’t see the real benefit except you can read the dial from an angle better, but what about future services for the watch, like changing the battery etc.
