The Aquanaut 5164A combines a 40.8 mm steel case with a black embossed dial and practical dual-time functions. Its rounded octagonal shape and Tropical composite strap make it more casual than a Nautilus while preserving the integrated sports-watch feel.
The source listing describes a 40.8 mm stainless steel case, sapphire caseback, black embossed dial with applied numerals and luminescent markers, self-winding travel-time movement with local and home time, day-night apertures, local date, sweep seconds, and a black composite strap with Aquanaut-style fold-over buckle. Water resistance is listed at 120 metres.
The dial combines the embossed Aquanaut texture with readable time-zone information and apertures for day-night indication. During inspection, check hand and date alignment, the local and home-time controls, crown operation, and the fit of the composite strap. The steel case keeps the weight manageable for daily wear.
This reference is suitable for travelers who want the Aquanaut's casual profile with useful dual-time functionality. It is less formal than a Nautilus and pairs naturally with the composite strap, making it a practical everyday option for buyers who value utility over a bracelet.
