The Seiko reference 6117 was only the second GMT complication the brand brought to market after their World Timer. Today this reference sits up with the iconic 6105 diver as one of their most significant tool watches, especially with the recent news of their limited edition and well-executed reissue. It's worth noting that as a GMT and pilots watch this reference has had documented use in the Vietnam war. Collectors now covet this rare Seiko for its grey dial and slim 38.5mm case. This particular example boasts great overall dial/bezel condition, as well as an unpolished case. The bracelet has seen some use but feels extremely comfortable as a result. Having just come back from a complete overhaul, this piece is ready to go for decades to come.
