By TLex The new DEEP BLUE Sea Chrono 1K houses a Japanese Quartz calibre, the Miyota OS10. The watch has a 45.5mm x 15.5mm case. Further features include: a sapphire crystal, a helium escape valve and a water-resistance of 1'000m. Its 'waffle' dial is available in four colors; black, blue, green and red. MSRP is 499USD. The watch does very little for me I'm afraid! This one's OK, though . . .
