At the end of 2015, Corum enriched its Bubble family of watches with three new models – Bubble Sphere 2, Bubble Drop and Bubble Paiste.
The Bubble was actually envisioned by the late Severin Wunderman, who took inspiration from an experimental deep-sea dive watch from the 1960s. This iconic model was tooled with a huge domed crystal to resist the pressure of the ocean.

Corum Bubble Drop Watch Profile
For the past decade and a half, since the very first Bubble timepiece was introduced, this line of contemporary wristwatches, with large and tall sapphire crystal, became a big hit among watch aficionados all over the world. With these three newcomers, Corum celebrates the 15th anniversary of the flagship model.
The original Bubble measures 44mm in width which was for that period a quite wide timepiece. Furthermore, it was distinguished with a pretty unusual design. Although, this iconic model was wide, these newcomers are much wider. Each od them comes with the 47mm wide case with the amazing thickness of 18.8mm – of which 8mm is down to the sapphire crystal alone.

Corum Bubble Drop Watch
Corum designers optioned for “Op-art” (optical-art) dials for two new models. These clever patterns give the sense of movement, together with depth and shadow. Both newcomers have been designed in collaboration with the industrial designer, Nicolas Le Moigne, who recreated two new motifs inspired by Op Art principles. The first model is Bubble Sphere 2 (ref. L082/02849) that features a brass dial and a PVD-coated blue-toned stainless steel case, whereas the second version which is named Bubble Drop (ref. L082/02848) has been completely brown PVD coated.

To create third new model Corum has partnered with a famous cymbal manufacturer, Paiste. Paiste has been enlisted to create a unique dial for the Corum Bubble Paiste special edition timepiece (ref. L110/02871). Its dial is a tiny cymbal crafted by Paiste in precisely the same way they would make a full-size cymbal.

Corum Bubble Paiste Watch
When compared with the Op-art timepieces, the Corum Bubble Paiste watch doesn’t feature the Superluminova, but it possess an attractively muted bi-color scheme of black and brass as a result.
Each of these three new Corum Bubble timepieces is powered with the caliber CO082 automatic movement which is capable to provide around 42 hours of power reserve. The mechanism beats at a rapid frequency of 28,800 vibrations per hour (4 Hz). The water resistance is assured down to 100 meters (about 330 feet).
These beautiful Bubble timepieces are produced in the exclusive limited edition of 350 specimens. The two Op Art models can be purchased for $3,750 each, whilst the Corum Bubble Paiste watch comes with the retail price of $4,200.
The new timepieces are attached to rubber straps topped with leather, featuring a buckle that sports the case finish. The straps start out at 24mm between the lugs and decrease to 20mm at the buckle.
