Based on the jump hour star system invented over 150 years ago, the British watchmaker deconstructed this vintage complication four times to display the inescapable passing of time, where hours literally “jump,” advancing from one to the next in the apparent blink of an eye.
The Speake-Marin Jumping Hours contains four small, Foundation-style, blued–steel hour hands. Each of these exquisitely crafted hands is placed in a separate quadrant of a beautifully finished silver dial – at 12, 3, 6 and 9 o’clock respectively. The individual hands are set atop their own brilliant, gilded star wheel, which “jumps” every 15 minutes when a tiny pin – located at each wheel’s centre – sequentially pushes one star wheel after the other as the blued-steel central minute and second hands perpetually march forward.
Jumping Hours’ evolution of time is all housed in the iconic, 42mm red gold and stainless steel Piccadilly case. The entire piece was constructed, machined, hand finished, assembled and regulated by a single watchmaker.
The Speake-Marin Jumping Hours is a unique piece.
