Here's a vintage Certina DS 288 in steel and silver with a glorious NSA bracelet.
Check out that minty dial with the chunky markers.
This hunk of steel is 42mm across, excluding the signed Certina crown...by 44mm from lug to lug. The starburst finish on the case is excellent, with a few scratches as you'd expect. But nothing to detract from the appeal.
The automatic movement keeps excellent time.
The NSA bracelet fits a 7.5 inch wrist snuggly, probably better for a slightly smaller wrist. It does, however, have a spring loaded diver's adjustment.
This is 70s cool.
