The PLT-1/P4 Replacement LED Module

If you have a Pulsar, Hamilton or Omega LED watch that no longer has the original module installed and sadly looks like the picture below, we now have a solution to restoring this type of modules, a legacy of the 1970's repairs. This revised version of the PLT-1 replacement LED module called the PLT-1/P4 would allow the installation of the later P4 LED displays removed from these modified modules, restoring original functionality as well as Magnet setting capability of the original pulsar watch module. The PLT-1/P4 is now available and costs the same as the standard PLT-1 module. Reed switches are not included but are available separately if needed. The PLT-1/P4

A 1970's Repair! We have had a few Pulsar LED watches and modules come for repair recently that had been repaired way back in the 1970's and look like the picture on the left, Yuk!! This repair / modification was probably done under warranty by Pulsar or soon after as these modules all look very similar with the same layout and wiring. It was probably a standard Pulsar repair to fix dead watches. Maybe when stocks of the original replacement modules ran out, Pulsar or their service and repair centres resorted to replacing the dead faulty modules with later P4 LED modules that were still in production, running wires all over the place to make everything fit together, what a mess!

The early P4 modules were magnet set and the magnet setting was retained in the modification, the later P4 modules were button set. With button set P4 modules, the time and date setting reed switches were no longer necessary and were removed or left unconnected, resulting in a watch that was no longer settable by a magnet!

These P4 modules use a different updated LED display with solidly lit LED segments and a different pin out to the original LED displays that were installed on the original modules. To fix these type of modules we developed a revised version of PLT-1 replacement modules which allows installation of the later P4 displays removed from these modified modules.
