The Seiko Presage GMT Rusty Nail Cocktail Time SSK039J is a men’s automatic watch featuring a deep chocolate brown dial, with a 40.5mm case size.This model, part of Seiko’s first Cocktail Time series with GMT functionality, draws inspiration from the ‘Rusty Nail’ cocktail—a blend of Scotch whisky and Drambuie with a hint of smokiness and honey, garnished with lemon peel, which mirrors the watch’s brown dial.The dial’s sunray finish evokes the look through a cocktail glass. The GMT hand resembles a cocktail glass stem, while the second-hand acts as a stirrer. It tracks two time zones with Arabic numerals at each index, Dauphine-style hands, and a date function at 3 o'clock. The watch is paired with a brown leather strap.The SSK039J has a 40.5mm case, 12.8mm thickness, 47.5mm lug-to-lug size, 20mm lug width, and weighs approximately 70g.
