Casio Wave Captor radio controlled watch, WR50M
Every now and then resets to some sort of default, 01 01 2005 data and
Tokyo radio system , so never resets to local time codes. Have to then reset it manually. No problem suggesting a low battery or any other timekeeping problem. I've tried holding down various buttons to check if its due to bad switch contacts but never induces this default. |

There will be a memory-keeping capacitor in there somewhere that is going either faulty (age) or intermittent (cold solder). Either way, replacing it will fix it.

Resetting the thing , before doing so , of course |

Stayed proper time for 2 hours now, whether it stays un-reset for the next week, the longest otherwise, we'll see. |

There's a reset in there by shorting 2 test points - you usually have to do that after replacing the battery. Can't hurt to try that, and its a good excuse to put a new battery in anyway. Lithium coin cell shelf life is somewhere in the direction of 10yrs, but mine uses the oddball CR1620, so who knows how long its been hanging on the display rack. |

I'll probably go in there later this week. At the moment I'm checking it runs normal non-radio control for a few days. Set it to London time yesterday, and did not engage RC!, at some point it decided to move its time zone to New York time so 5 hours behind. Pressing button C, brought it back to UK time, currently still the "normal" slightly wavering correct UK time having passed thr a very cold night |

It decided of its own accord to engage radio control and has run fine since, including very cold nights. I decided to grind back all 4 plastic knobs, so a fingernail is required to operate, and as hollow buttons , some hotmelt in there to stop dirst entry. Why this watch and most of the cameras I've owned plus a "Dremmel" without a shroud around the mains switch (serious safety issue there). A crazy business having to recess switches and shroud switches on handled and transportable mainstream products. I'll give it anothe rweek , on probation |

Change of title, just noticed its Wave Ceptor It reset to 2005 yesterday, so I went inside. Removed battery and delved deeper. Safely got to both sides of the pcb , one SMD had about 200mV on it with no battery supply. Have to find more technical info on all this |
Casio Wave Ceptor radio controlled watch, WR50M
I could not find any pics of the internals of these watches, so pic here
http://diverse.4mg.com/casio_wr50m_r.jpg The wire to the antenna broke , handling the pcb for this pic and self-weight of the small coil, not before, but it is obviously a week point at the solder points if subjected to a lot of vibration. For the moment I'll clean battery and contacts and reaasemble to check that I can and run for a while, until date 2005 returns presumably, and hopefully find out more info on the internals. The yellow caret marks a SMD with 200mV on it 20 minutes after removing the button cell, 3.06V open cct voltage. Seems 3 crystals relate to the radio blob and 1 for the watch. Red is my mark for +ve so I can solder a pair of wires to convenient spot , to power from 3V to monitor some DC levels at least, next time of playing with it that is. Beware of the tiny phosphor-bronze spring dropping out, on disassembly of the 2-part plastic sub-frame, it connects to the piezo sounder. Battery contact simply slides to release battery. A number of tangs need prizing back with a needle to release the metal screen and 4 spring tangs for the button returns. |
Casio Wave Ceptor radio controlled watch, WR50M
Reassembled resoldering antenna wire and a small spot of hotmelt glue
"strain relief", deliberately leaving out the piezo contact. Watch returned to non-rc function but button A spring must have been misplaced and no function. Could reasign London instead of Tokyo and left in timesetting mode , with flashing seconds. It later dropped into normal timekeeping mode and could then select RC! , we'll see if full function returns and then go back inside with more confidence, to take voltages and play with SM or whatever. |

Survived a week, with no 2005 reset , no loss of LCD segment or anything
other than the manageable loss of button-A. The only change was cleaning battery contacts and of course electronic repairman's conundrum - close handling of the pcb, upsetting a bad solder-joint etc interpretted as whatever else done at the time,interpreted asa repair.. |

Half the art of repair is being able to take something apart and then be able to put it back together again. So successfully half way to repairing this thing. |

2 weeks on and no problem, passed through to daylight saving time
automatically yesterday. So perhaps cleaning battery contact points, and bending contact metal is all that was wrong. Otherwise leaving out the piezo spring contact-unlikely or close-handling , the big unknown |

So, how much did this piece of crap cost new? And how many hours did you waste "fixing" it? The one i bought was £60 - £80 by the time I opted for the SS bracelet. Last I saw advertised was somewhere around £140. One of the discount stores did a very basic radio controlled watch for £15. The waveceptor let go of its bracelet mount after at least a decade use, I've gone through a couple of dumpster diver's watches before unpacking the cheapie. There's a growing collection of watches in a drawer - sometimes circumstances align to make one of them a simple repair. |

If it ain't broke, don't poke: replacement battery and disconnected spring contact remain on the outside. I have a Waveceptor, don't know the module number, but it's "solar powered". I don't use the backlight much, but what I remember is I got it in the spring of 2006, and it's still running fine on the first battery. At one time, I accidentally activated the function where if you move the watch at a certain angle the backlight comes on, no need to press a button. Before I figured out how to reset that, the "battery indicator" was down one bar, I think the only time it's never been at "full power". I paid about 20 dollars for it, wanting the "atomic watch" aspect, but it's nice not to have to change the battery. I know on my previous Casio, somehow the replacement battery lasted a very short time, and then the strap broke, so I abandoned it, rather than buy a second battery so soon on top of needing a new strap.

I have a wave ceptor and the tiny antenna has separated from the indentation in the frame of the watch (my fault). Do you know if theres any way of fixing this.
