The signature design throughout the series: The unique left-side crown layout: This series continues the U-Boat design… The signature left-side dual crown design features one crown for adjusting the main time and the other for controlling the dual time zone function. This design distinguishes it from the conventional right-side crown design and makes dual time zone adjustment more convenient, aligning with the brand’s unique military-inspired heritage.
Practical dual time zone compatibility: All models come standard with a bidirectional rotating inner bezel, with markings covering the hour and half-hour intervals. It accurately synchronizes with the second time zone hand, allowing business travelers who frequently cross time zones or outdoor adventurers to quickly read the time in different time zones, maximizing practicality.
Differentiated dial craftsmanship: The Capsoil version’s oil-immersed dial is a highlight of the series. The oil not only enriches the dial’s color but also creates the visual illusion of a “crystal-less” dial. The non-Capsoil models feature a minimalist, retro style, using different color schemes and materials to balance luminous readability with everyday aesthetics. popular swiss watch brands
