Chelsea's 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, 364 precision brass parts – many plated with gold – and an-11 jewel movement, all of which are made in Chelsea, Massachusetts, ensure accuracy in time and enduring quality for years to come.
