To the guy with the battery question. Just Google search for mbw-150 battery. Replacements are now readily available thanks to xda members.

Moisture is also a leading killer of oled displays. I think our problem is that Sony didn't seal these units as well as they should have.

To everyone else, been busy with work lately, getting the hands removed soon to continue this project. Just gotta find time to get to a shop.

OK, thank you!

I just received my MBW-150 Music! i love it!
Still perfect display

"Fading display" will happen 100%, and it is just matter of time?
Or this happens only on some devices?

I don't have problems, but I will subscribe to your thread, just in case

Mine just arrived from here: http://www.thebatterystore.com/batte...ndmbw-150.aspx

I think $19.95 plus $9.67 shipping and handling is a ripoff, but I was able to get two for the same shipping, so they were "only" around $25 each!

What about this?

According to some internet pages, this should be the same battery, but without connectors and insulation.
Three versions, I guess cheapest one ($7.50) would be OK if you know how to solder.

If changing OLED display will work, then netstat_EVO should buy a lot of displays and batteries, and he could be service center for MBW-150, covering whole world

Hey guys, sorry to spoil the party here, but I have a cautionary tale that will hopefully prevent others from totally destroying their MBW-150.

I was also excited about the prospect of getting my dim OLED repaired. But I got impatient (happens a lot), and decided to dig-in. My thought was to take the good OLED from my "executive" model (I don't care for the metal band), and use it to replace the dim OLED in my "classic" model.

Now, I'm not a watch expert. But I'm relatively tech/mech savvy. So I unscrewed and removed the back without incident. The battery is right there, and can be easily replaced. However, I'd recommend getting a pro to do it, so that they can replace the water seal on the cover before closing it. Anyway, that's about all I'd say can be serviced on the watch.

To get the rest of the watch out of the housing, you need to remove a few more screws, and you also need to remove the crown (the thing you use to set the time on the hands). I don't know how to remove the crown, and ended up breaking the spindle in the process. Oh, well; at that point, I knew I was hosed. So I figured I'd learn what I could so I could post it here. I assume that someone more knowledgeable about watches could remove the crown without damage.

Now, the way the "movement" is constructed, there's a main board sandwiched between the "face" and a rear plastic housing. The OLED is, of course, on the front side of the board, which means you need to remove the face to get access to it. As netstat_EVO mentioned, that involves removing the hands. I couldn't see how to do that without damage. Since I knew I was already hosed, I just broke them off. Again, I assume an experienced person could do that without damage. Then the face slides right off, and there's the OLED.

Now here's the kicker. The OLED is attached to the main board by a short ribbon cable. And that cable, with its two dozen or so thin leads, is totally baked onto the board - no socket there, at least not on mine. Now, I could be wrong, and if so, someone please correct me. But I don't think that cable can be removed from the board without destroying the "landing" area. Probably someone with the right tools could do the repair, but those would be some pretty specialized tools. I'm handy enough with a soldering iron, and I can tell you, that wouldn't do it.

I still have two MBW-150s, and I love them. (OpenWatch on Android rocks!) But now I'm resigned to the fact that eventually the OLEDs will die. And aside from being reasonably good looking watches, they won't be anything special.

If you think you'll have better luck than me, then by all means, please try! I wish you the best. And thank you very much to netstat_EVO for posting your info!

There isn't so much doom and gloom in the disassembly process. Sounds like you ran into some pretty bad luck.

I have already had mine apart to the point where removing the hands to gain access to the OLED was all that I still needed to do.

As for the rubber seal, getting it to seat correctly isn't that big of an issue, and I doubt that a watch shop would be able to replace it with a new one (we all know how Sony is about parts for these )

The crown (thanks btw, I didn't know the name of that part. I just called it the time changer thing) that is actually pretty easy to remove. You just have to pull very very slowly and evenly and it will eventually just pop right out without breaking.

Still trying to find time to get to a watch shop to have the hands removed... I took on a second department to manage at work and time has been at a premium lately.

Completely get the 'hard to find the time' thing as our 18 month old keeps us running, but any change for an update? My screen is totally gone now, but love the watch.

so if i understand it correctly a watch shop could install a new oled display when provided?
oh and what about the expected life span of the displays? i couldn't really work that out from the previous posts
i'd love to try it because i recently bought a second hand mbw-100 with dead oled without knowing that buying a new watch would be better

Any update on this? I bought a second MBW-150 to hold me over until you got this figured out, and now its display is starting to fade too.
