These simultaneous displays of time and astronomical distance are now enriched by an ancient material called electrum, a gold and silver alloy used by ancient Greeks and Egyptians to make their coins. The muted yellow gold appearance is made more distinctive by pleated patterns for a tactile case. Available in a limited edition of 25 pieces.

A central tourbillon, rare even in haute horology, is framed by a circular disc on which two diamond-shaped 'hands' that move along a 180-degree minute track in the bottom half of the dial. The first hand indicates the minutes, and by the time it reaches the 55th minute, the second hand will make a quarter turn in preparation for its turn. The first hand will retract when the second hand takes over. The jumping hour appears in an aperture at '12'. 

This intriguing operation is made possible by the patented Papillon, which consumes less energy than the traditional retrograde hand that jumps back to minute zero. Still, Calibre BVL 332 possesses a robust 60 hours of power reserve, indicated on the caseback. The watch comes in 41mm rose gold case.

MB&F's 14th collaboration with Swiss clockmaker L'Epee 1839 may be aptly called the Orb but it's also flexible enough to take multiple forms. The clock is composed of four mobile wings that can open and swivel—in fact, it can go from a ball to a flower in bloom in seconds. It comes with a saucer so you can also display it with one, two or three wings open. 

Made of aluminium and lacquered for the luxe finish, its mechanical heart is based on a similar mechanism found in L’Epée 1839’s historic carriage clock and chimes the hour like a church clock.

Injecting levity into the series of high-end serious watches is this fun timepiece featuring one of history's most beloved cartoon characters, Mickey Mouse.

For a perpetual calendar, the new Streamliner's understated dial belies its complexity. The date aperture at '4' features instantaneous jump of the numeral at midnight, a novelty consisting of two superimposed discs which operate one after the other, from 1 to 15 then from 16 to 31. To discover the month, one has to have very good eyesight as it's indicated by a very small central hand in white and red, with the hour indices doubling as the month. To keep the dial clean, the leap year indication is on the caseback. 

A flagship model of Girard-Perregaux, pink gold is used for the first time to craft all three bridges, according to its press release. The upper and lower surfaces are coated in black PVD, but the sides are left alone for that hint of shine. A study in lightness and transparency, the bridges, which support the tourbillon, gear train and barrel, are displayed in their full glory on the dial and on the caseback. 

A nod to the 1960s Top Time watches, the latest collection also pays tribute to a trio of racing cars. Sporting a red and black dial, the Top Time Chevrolet Corvette is inspired by Corvette C2, also known as the Sting Ray. The green-and-brown Top Time Ford Mustang is based on the 1964 car that became a firm Hollywood favourite, with numerous appearances on the silver screen. 

Top Time Shelby Cobra features a blue and white dial, and is based on a creation by Carroll Shelby that combines British design and American engineering. All watches are endowed with COSC-certified movements.
