Here's one of the greatest hits from Helvetia: a Depth Gauge diver from the 1970s era of funk and functionality.
Take in that amazing dial, in blue and silver, with red outer depth scale pointers and, in an unusual twist, two tiny rivet screws in the dial.
The solid stainless steel sun-brushed case with high polished bevels is a massive 43mm across, excluding the unsigned, screw-down crown...by 43mm from lug to lug.
It is in excellent condition, with only a few light scratches on the back of the case and elsewhere. Nothing to detract from the immense appeal of this classic.
Under the hood a 25-jewel Helvetia automatic movement, keeping excellent time.
