Hamilton QTC/QED

[T_Savalas]

Can any help me please! I have a Hamilton QTC/QED watch from 1974. The
watch Telly Savalas worn on show. The problem is regarding battery
replacement. Originally the watch had RW25 battery and my research found
a replacement a 357 battery with spacer that I purchased from
batterybob.com . Here is what happened when I tried replacing the
batteries today. I put the spacers in each of the two slots and put the
batteries in correctly one up and one down. The watch did show a single
digit light up a zero. Since the didn’t have the magnet handy and
hadn’t secured the ring, I laid watch done removed magnet from clasp
and applied the magnet a second time and the digit didn’t light up.
Does anyone know what the problem could be? Many thanks in advance for
any help you can provide. Does Hamilton even service for a digital 40 year
old watch.

Hi T_Savalas and welcome to the DWF! In the case of your QED the problem might be a faulty quartz crystal or a faulty oscillator.
Please don't forget to write your location in the profile, so we know where are you from!

With a replacement of the quartz crystal, the watch might work again, otherwise the solution to resurrect it is to convert the module to a SASM one.

You can to talk to our administrator Hanno (SASM) at StrikesAndSpares , he can make a SASM module out from your old one. A SASM module is made with the parts of your old module (display, light sensor, reed switches, plastic carrier and the quartz crystal -if it's not faulty, otherwise that part is replaced as well-), to ensure the maximum compatibility and the same look-and-feel of the original module: it'll look and work exactly like the original module, without any visible difference, except for the "SAS" sign appearing for a second when you change the batteries, that shows the module is a SASM one. A SASM module is the best way to make your Hamilton work again. It's reliable, has a lower battery consumption and it has a one year warranty.
