Needing little in the way of an introduction, the 6138-8020 "Panda" is arguably the most sought after addition to every vintage Seiko collection. Finding clean, unmolested original examples has nearly become an exercise in futility. The market is full of cobbled together goods, rife with aftermarket dials, hands, tachymetric rings, pushers, and overly polished cases. You’ll find none of that here. This example from April of ‘77 is phenomenal. It is in fantastic condition, and absolutely original aside from a replacement crystal. A description of what makes this watch noteworthy and important will be forgone in this listing. It is what it is, and a true opportunity for those looking to add one to their own roster. All functions are operating smoothly, and post service, the 6138B is keeping near perfect time. We’ve strapped it to a smooth chestnut leather with black stitching for clean casual finish, and comfort on the wrist.
