One of the most iconic watches ever launched by Corum was the Bubble in the year 2000 and the watch is making waves since its re-launch in 2015. A super-sized watch with an even larger curved crystal – the Bubble is so far-reaching that it has become a must-have timepiece of the new millennium. The watch has sealed its place as a pillar of Corum’s watchmaking heritage with its large diameter and a towering sapphire crystal so tall it towers above the dial. With a size and shape totally unprecedented in watchmaking, the Bubble has become an instant hit.
The Bubble was the brainchild of the late Severin Wunderman, a relentlessly creative entrepreneur who acquired Corum that very same year. Wunderman, who survived both the Holocaust and cancer, had a roving, creative mind. In one instance, he was inspired by an experimental deep-sea dive watch from the 1960s, which was fitted with an enormous domed crystal to withstand the pressure of the ocean. That formed the genesis of the Bubble, one of the most recognizable wristwatches of its time.
While the Bubble was unquestionably unique, its unorthodox design was merely an extension of Corum’s long-established philosophy. Since its founding in 1955, Corum consistently excelled at designing totally original timepieces, ranging from the Rolls-Royce, shaped like the luxury automobile’s front grille, to the Golden Bridge, distinguished by its remarkably tiny, baguette-shaped movement.
Despite being a mere 16 years old, the Bubble is major part of the brand’s heritage, deserving of elevation into a hall of fame. The Bubble has now been revived as part of the Corum Heritage collection, putting it alongside other landmark timepieces like the extra-thin Coin Watch.
While retaining all the design codes of the original, the 2015 Bubble is not a mere replica of its predecessor. Fitted with a rubber-ringed, spherical crown, the case is a collection of smooth, rounded lines, just like the original. The diameters has been enlarged to 47 mm, lending it impressively striking proportions, especially as it stands some 18.8 mm high, crystal included. But, as always, practicality was high on the mind of the development team, which paired the oversized case with short, curved lugs, allowing it to hug the wrist snugly.
A remarkable 8 mm high, this sapphire crystal is one of the largest of any watch. Sapphire is a material so extraordinarily hard it has to be cut with a diamond-tipped tool. This in itself is challenging enough that even when machining ordinary, flat watch crystals the job can take hours. Crafting the mountainous crystal of the Bubble requires exponentially more work. The task starts with cutting a block of crystal, then grinding it into a bubble-like shape, and finally polishing the crystal to flawless clarity with absolutely no optical imperfections.
Because the sapphire crystal is so tall, it acts as a lens, both magnifying and distorting the dial. Corum’s designers took advantage of this by designing a dial with a clever, op art (short for “optical art”) motif. Taking inspiration from Hungarian-born French artist Victor Vasarely, founder of the op art movement, the dial is decorated with squares in graduated sizes that grow larger toward the center of the dial.
Op art desired to create static patterns that gave the impression of movement or surprising, contradictory perspectives. Likewise, the dial of the Bubble is perfectly flat, formed from a lacquered, brass disc stamped with the cube motif, but appears sharply domed. In fact, it looks so rounded it might pass for the top of a sphere.
This arresting op art dial will be fitted only to a pair of limited edition, PVD-coated versions of the Bubble, each made in an exclusive run of just 350 pieces in bronze-brown and blue. The first is the Bubble Vintage, housed in a bronze-tone, PVD-coated case paired with Super-LumiNova treated for a vintage effect. A modern watch made to look like an antique from an indistinct era, the Bubble Vintage is a nod to the original Bubble now 15 years old.
