The Seiko Presage Style60’s GMT featured in Seiko’s 2023 Laurel anniversary release is reference SSK015. It pairs a mid-century-inspired design with automatic Caliber 4R34 and a separately adjustable 24-hour hand. Seiko announced it as a 3,500-piece limited edition for release from October 2023; its launch specifications and prices are historical, not confirmation of today’s stock or pricing.
What is the Seiko Presage Style60’s GMT SSK015?
SSK015 is the reference for the anniversary Style60’s GMT in Seiko Watch Corporation’s 6 September 2023 announcement. It was one of the releases marking 110 years of Seiko watchmaking, and Seiko stated that production would be limited to 3,500 pieces. The company announced availability through Seiko boutiques and select retail stores from October 2023.
This specific reference should not be confused with other GMT watches currently presented in Seiko’s Style60’s collection. The SSK015’s launch details come from the 2023 announcement; they do not establish whether the model is still sold or what it costs now. (Seiko’s 6 September 2023 announcement; Seiko Presage Style60’s collection)
Design: a mid-century look with a blue GMT hand
Seiko connects the Style60’s design language to its 1964 Crown Chronograph. The collection draws on features such as box-shaped glass, faceted indexes and sharply designed hands. On the SSK015, Seiko highlighted the blue GMT hand, blue hands, a red mark at 12 o’clock and Lumibrite on the hour and minute hands. The company described the result as having “an unmistakable mid-century appearance.”
