In
December 1975 Pulsar released the worlds first wrist LED 18k
calculator watch.
The first 100 units where offered for sale at the modest price
of $3950.
Story goes Betty Ford refused to buy one for president Ford
as a Christmas present as it was too expensive. I believe he
got one in the end.
The first 100 units sold straight away, so Pulsar I believe
produced another 400 unit, some with different clasp variations.
