Seiko 0634-5009: help!!

[bricem13]

Hello

As it is my first post here, let me introduce myself. I am 32 living in Switzerland. I have deep interest in mechanical watches watches in general) and seiko in particular. I especially like divers and mechanical chronographes and own quite a lot of them (30+). I generally take care myself of my watches and feel confident servicing a mechanical watch. However I have a growing interest in digital watches (still seiko of course), amd I came through at a local auction site on a 0634-5009.

Watch was advertised non working and I got it quite cheap. I disassembled it, cleaned it but I believe module is dead (light however is OK). In my first experience I turned to be unlucky : I cleand lcd contacts with lighter fuel but did not wait enough before reassembling lcd on module... what generated some sheer stress on lcd and it broke partially (is now in 2 parts...).

Therefore I come to you, module is available in US but lcd is another story... so if someone here might help then please PM!

Best regards
Brice

ps: of course I chase other lcd and will come back when I catch something interesting.

Welcome Brice to the forum.

first, try to post a picture of the watch in question..a picture is so much easier for everybody..i know the watch from memory but not everybody is a lcd fan.
An Broken lcd is in most cases a problem. It's not easy to find a spare.
Maybe you could ask Seiko Kid (pm him) if he can help you further.

so be patient here cause not everybody is looking at the forum every day.

and yes..post some nice watches for viewing

Hi Brice

The situation with repairing - sourcing a beater is still the same as I explained to you on the Seiko Forum

Modules can be sourced from the US but they are not cheap and you will pay customs. LCDs you have to find out of other watches on Ebay as they are no longer available unless you know a witch doctor. You didnt tell me that you had snapped the LCD??

Lighter fuel is not a good idea to put on circuit boards


Hows the collection growing / going Kasper?

Hi

Yes I was a lot pi**ed off by the lcd that I did not say anything. I did not put lighter fuel on the circuit board (I tried with special spray for electronic circuits). Lighter fuel was used instead of benzine as to be found in the seiko 0634A caliber datasheet. I used it for cleaning the contacts but I apparently did not wait long enough before re-installing the lcd... BTW what's the correct procedure for re-installing the lcd ? the spring shall be on on one side and then simply push on the other side of the spring ? I feel it put a lot of tension on one side of the lcd...

Regards

Well, you learn something new everyday!

Ive never really read the writing on the data sheets. I just follow the pictures and have always known to use alcohol ( isopropanol ) to clean electrical contacts.

Old Tom on here is probably the best person to answer this as he has a good electrical and chemical knowlage.

Moving over to the LCD. These units are difficult if your not experienced with them. Back on my first unit I created a bleed in the LCD due to not having the experience, basically you fit the top half of the LCD spring into the 2 retaining lugs and then, carefully you click the bottom single clip into place. Sometimes you have to push it further onto the clip so it seats properly.

From what you say regarding it snapping it sounds like you slipped or pushed very hard.
