National semiconductor module help!

[pasha_m]

I wonder if anyone can help , I have a qualitron led watch which has a national semiconductor module which is broken,
I have tried endless sites for a replacement module including ebay etc...
Dose anyone have a spare module that I could have / buy ?

Hi buddy, there is not sites that I know selling NS modules, Ebay is where You have more chances of finding one but not by itself
You have to keep an eye for a working module on an ugly case, NS came in many flavors on the 29mm men. early dot display time only, dot time and seconds, dual time with and extra pusher at 8 O'clock, 6 functions "DOW', All are 29mm and interchangeable. almost every watch with the pushers at 2 and 4 O'clock is a NS with the exception of Collins.
someone correct Me if I 'm wrong. You shouldn't pay more than 40 US dollars but aim for less. In me experience You will have not trouble finding one, a lot where made and are very reliable. If You have a problem finding one let me know i can Help. Ismael from california

Thanks for the reply , I have tried ebay in the past and have bought watches in the hope of finding the right module ,
I looked recently and watches are going for around 60 dollars plus shipping and import charges as I live in the uk .
The module is one of those red led ones , 1970s , and dose nothing fancy .
If you do find one please let me know I would be very grateful .

Hello, is your watch a one button or two button variety? NS made both types. Sharing a picture of your watch case will help.

Yes, please post a picture. I just produced a new series of modules, which replaces modules from Girard Perregaux (SASM54) National (SASM55) and Hughes (SASM56+57). I should receive the circuit boards in about 10 days. Maybe that could be an option for you.

Best regards, Hanno.

That will probably work. I have the same module by National Semiconductor, so I will test it with my module first.
