One of the most feature rich watches we've seen, the Oceanus Solar Atomic Chronograph packs atomic timekeeping, solar power, dual analog/digital display, 1/100 second stopwatch, 5 daily alarms, a scratchproof sapphire crystal, 100 meters of water resistance and LED lit dial into a handsome, traditional looking men's watch with high tech accents. Oceanus watches actually synch up automatically several times daily with the national atomic transmitter for exact accuracy anywhere within 2000 miles of Fort Collins, CO. Sunlight or indoor light charges the internal battery which will hold a charge for several months. A power saving feature preserves power when the watch is not in use. Model OCW510LA12 features a dark navy dial, solid stainless steel case and black leather strap.
