This distinctive, handcrafted timepiece signals the passing of time with gentle, rich-sounding chimes – eight bells at 4, 8 and 12 o'clock to mark the end of a mariner's four-hour watch, with one bell the first half-hour after, plus one additional bell with each subsequent half-hour. Behind its classic, hand-silvered dial, 290 precision brass parts and an 11-jewel movement, ensuring accuracy in time and enduring quality for years to come. Since the first patented Ship's Bell left our factory in 1900, it has been held as the standard by which all other Chelsea clocks are measured. Our classic Ship’s Bell Barometer, designed as a companion piece to the Ship’s Bell Clock, features a double bellows holosteric movement that mechanically measures changes in atmospheric pressure to foretell changing weather. Readings of “Stormy,” “Rain,” “Change,” “Fair,” or “Very Dry” are handsomely displayed in inches and millibars on the piece’s rich, hand-silvered dial. The 4" and 6" dial editions of this precision instrument also include a thermometer tube that provides accurate temperature readings. The Ship’s Bell Barometer features a lacquered solid forged brass case and screw bezel. Barometer movements are automatically calibrated for altitudes up to 2,000 feet, and can be factory-adjusted for altitudes up to 5,000 feet above sea level upon request when placing orders.
