I have a total of 60 of these modules for the Original Pulsar 3502 mens sport model .
They are all in perfect working order.
The price is $75 per item.
These modules will also fit the Gold Filled men dress touch model Pulsar watch.
They do not fit a P2, P3 or P4 model Pulsar watch.
I have personally tested each module..
They are factory leftovers from when my Dad and I ran Pulsar Repair service
In Lancaster, PA back in the early 80's
I will ship worldwide
