Speake-Marin Jumping Hours

Jumping Hours, part of Speake-Marin’s Cabinet des Mystères collection, boasts four separate jump hour indications, each controlled by its own gilded star wheel, are a constant reminder of the ceaseless passing of time.

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.
In a neat touch, synchronised with this changing of the hours is the appearance of a tiny red dot on the centre plate at each quarter hour mark. Every 15 minutes, a small circular hole near the base of the minute hand lines up with the red dot, indicating that the hour has “jumped”.
The Jumping Hours "dial" is actually the top of the movement mainplate. The movement, crafted from traditional German silver, features circular-grained bridges and plates with hand polished bevels. The distinct curvature of the bridges gives the illusion that the dial is moving in step with the hour hands as time strides forward. So as not to distract from the action of each passing hour, there are no numerals on the dial. Instead, subtly drilled minute markers are neatly arranged around the perimeter of the main plate. The silver dial contrasts beautifully with the 18k red gold bezel. A matching red gold fluted crown and caseback adds an extra touch of classic Speake-Marin style. Serif style text in capital letters is hand-engraved inside the minute markers – an elegant touch and reminiscent of another era.
Visible through the display back is Jumping Hours’ Eros automatic-winding movement with long five-day power reserve and Speake-Marin’s signature ‘topping tool’ mystery winding rotor. Hand engraved around the caseback are “Unique Piece” and “Mechanical Art No. 2”.

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.
