Seiko 'Black Monster' SRP307K1 4R36-01J0 200m diver, near mint
$425.00
This is the second generation Monster, with the then-new 4R movement that hand-winds and hacks, and a new 'shark tooth' dial replacing the 1st gen rectangular markers. This particular example was a one-owner watch from new. It's unserviced but keeping amazing time - six seconds off after a week's run time! Amplitudes in the 240s with Seiko standard beat error. Watch is in excellent all original cosmetic condition. Barely any signs of use.
