SEAC – Apnea HR (black) Diving Watch

Seac Apnea Computer Watch offers a streamlined design that blends performance and durability. The glass‑loaded nylon polymer case and stainless steel bezel and buttons provide rugged reliability, while the black with steel accents and Seac logo adds energetic contrast.

A 26 cm strap fits most wrists with a 24.5 cm useful length and adjusts easily over thick wetsuits. A 38 mm crystal protects a 34 mm LCD display, where central 4 × 7.5 mm digits show time and depth rate, and smaller 3 × 7 mm and 2.5 × 6 mm characters display dive time, water temperature, and maximum depth.

Customize readability with adjustable contrast, backlight intensity/duration, or manual backlight mode. Base features include dual time, countdown chrono, and pedometer (steps, distance, calories). Dive essentials cover maximum depth, dive time, total dive time, and customizable alarms.

Special functions include the MSST algorithm for minimum surface intervals and a dehydration alert for safe diving. Record descent/ascent speed to refine technique. Download detailed dive logs via USB—date, time, depth, temperature—and dive with confidence. The Seac Apnea Computer Watch delivers professional‑grade reliability for freediving and spearfishing enthusiasts.
