Hi,
my favourite Pulsar is a Hamilton.
it's the classic HAMILTON stainless steel with date (one button on each side is better from an easthectical point of view), it has the big H on the clasp, the crystal is signed both Hamilton on bottom and with the H on top.
It has the Pulsar module , magnet set,with dot matrix display.
Same quality, different design.
And they come a little cheaper than the Pulsar but I think they are rarer as you don't find so many on ebay.
Am I right?
