The Seac Action HR stands out for its top-quality construction, featuring a special HR (High Resistance) treatment on the case and bezel. This advanced technology offers exceptional resistance to scratches, abrasions, and impacts that are common during the preparation or the course of a dive. Its robust design ensures that the watch will remain like new, protecting the internal electronic systems from intense stress and corrosion caused by seawater.

This dive computer is equipped with the globally recognized decompression algorithm Bühlmann ZHL-16C, which ensures maximum safety during ascent. It supports managing one or two gases in Scuba Mode, allowing you to switch between air and Nitrox (with oxygen concentration up to 99%) during the same dive. All calculations for decompression limits and safety stops are performed with absolute accuracy in real time.

For lovers of freediving and spearfishing, the Seac Action HR features the Freedive Mode function. In this mode, the watch accurately records the current and maximum depth, the duration of the dive, as well as the critical surface time. Monitoring the rest time between dives helps prevent freediving decompression sickness (Taravana), offering complete control and safety.

The LCD screen of the Seac Action HR is designed with optimal readability underwater in mind. It features clear, large digits and a powerful backlight that can be adjusted in intensity and duration, ensuring top clarity in murky waters or night dives. The watch also incorporates audible and visual alerts for ascent rate, decompression stop violations, and approaching maximum depth.

After every underwater adventure, you can refer to the built-in digital logbook, which has a recording capacity of up to 40 hours with sampling every 5 seconds. On land, the Seac Action HR functions as a stylish, everyday sports watch. It includes features such as a digital stopwatch, countdown timer, alarm, and second time zone display, while its highly durable strap fits perfectly both on the bare wrist and over your suit.
