A distinctive example from Swatch’s early Irony Chrono era, the Swatch Irony Chrono Rough & Rugged YCS400G combines bold 1990s chronograph styling with Swiss quartz reliability and a substantial all-metal construction. The watch features a sporty silver-toned case and integrated stainless-steel link bracelet, complemented by a detailed chronograph dial with contrasting accents and a practical date display at approximately 4 o’clock.
With its 40 mm case, acrylic crystal, four-jewel Swiss quartz movement and unmistakable early Irony design language, the Rough & Rugged is an appealing vintage Swatch for collectors looking for something more substantial than the brand’s traditional plastic-cased models. Swatch identifies the Rough & Rugged as reference YCS400G, while specialist records place examples from the mid-1990s, including 1995–1996.

Collector’s Note
The Swatch Irony Chrono collection represented Swatch’s move toward more substantial metal watches while retaining the brand’s accessible Swiss quartz philosophy. The Rough & Rugged belongs to the early generation of Irony Chronographs and is now increasingly encountered as a vintage 1990s Swatch.
The YCS400G is particularly recognizable for its all-metal construction, integrated link bracelet, 40 mm case and sporty chronograph layout. Contemporary and collector references identify the model as a quartz chronograph with date functionality and 3 Bar water resistance.
Its 1990s proportions and distinctive Irony styling make it an interesting choice for collectors of vintage Swatch chronographs and Swiss quartz watches.

Important Note
This is a vintage pre-owned timepiece. All specifications, including movement details, dimensions, battery type, water resistance, bracelet configuration and other manufacturer specifications, are based on the watch’s visible characteristics and available reference information and are provided for reference only.
For the YCS400G reference, available specialist records identify the case and bracelet as stainless steel rather than aluminium. The case measures approximately 40 mm in diameter and 12 mm in thickness.
Due to age, previous use, replacement of consumable components such as the battery, and service history, actual performance may vary. The original 3 Bar / 30 metres water-resistance specification should not be considered a guarantee of current water resistance. We recommend avoiding exposure to moisture unless the watch has been professionally pressure-tested.
The original acrylic crystal and stainless-steel finishing may naturally show age-related marks consistent with a vintage timepiece.
Please review all photographs carefully, as they form an important part of the description and accurately represent the watch’s current
